Full textAbstract:
Software product lines (SPL) is a software engineering method for creating configurable software systems that can be adapted to a variety of requirements. SPL uses feature models to document the commonalities and variabilities of products. The key challenge is to derive a product configuration that satisfies all business and costumer requirements. Customer requirements are usually neglected, although product configuration has already been investigated in the literature. This dissertation presents a search-based approach to tackle the problem of finding the optimal product configuration that maximizes the customer satisfaction. The latter is modeled as an optimization problem. An exact algorithm and a heuristic are proposed to solve the problem and implemented in a prototype tool. Computational experiments showed that the exact algorithm can find the optimal product configuration for real-life instances found in the literature and that the optimality gap of the heuristic is at most 3%.<br>Linha de produtos de software (LPS) é um método de engenharia de software para a criação de sistemas de software configuráveis que podem ser adaptados a uma variedade de conjuntos de requisitos. LPS comumente usa modelo de características para capturar e documentar as semelhanças e variabilidades de produtos. O principal desafio é derivar uma configuração de produto que satisfaça todos os requisitos do negócio e do cliente. Os requisitos dos clientes são normalmente negligenciados, embora a configuração do produto já foi investigada na literatura. Esta dissertação apresenta uma abordagem de engenharia de software baseada em busca para resolver o problema de encontrar a configuração de produto ótima que maximiza a satisfação do cliente. Este último é modelado como um problema de otimização. Um algoritmo exato e uma heurística são propostas para resolver o problema e implementado em uma ferramenta protótipo. Experimentos computacionais mostraram que o algoritmo exato pode encontrar a configuração ótima do produto para instancias reais da literatura e que a diferença entre o resultado heurístico e a solução ótima é de no máximo 3%.

Full textAbstract:
This research helps bridge the gap between conventional product support, where the support system is considered as a stand-alone application, and the new paradigm of responsive one, where the support system frequently communicates with its environment and reacts to stimuli. This new paradigm would enable product support knowledge to be captured, stored, processed, and updated automatically, being delivered to the users when, where and in the form they need it. The research reported in this thesis first defines Product Support Systems (PRSSs) as electronic means that provide accurate and up-to-date information to the user in a coherent and personalised manner. Product support knowledge is then identified as the integration of product, task, user, and support documentation knowledge. Next, the thesis focuses on an ontology-based model of the structure, relations, and attributes of product support knowledge. In that model product support virtual documentation (PSVD) is presented as an aggregation of Information Objects (IOs) and Information Object Clusters (IOCs). The description of PSVD is followed by an analysis of the relation between IOs, IOCs, and domain knowledge. Then, the thesis builds on the ontology-based representation of product support knowledge and explores the synergy between product support, problem solving, and knowledge engineering. As a result, a structured problem solving approach is introduced that combines case-based adaptation and model-based generation techniques. Based on that approach a knowledge engineering framework for product support systems is developed. A conceptual model of context-aware product support systems that extends the framework is then introduced. The conceptual model includes an ontology-based representation of knowledge related to the users, their activities, the support environment, and the device being used. An approach to semi-automatically integrating design and documentation data is also proposed as part of context-aware product support systems development process.

Full textAbstract:
Promoting constructiveness in online comment sections is an essential step to make the internet a more productive place. On online marketplaces, customers often have the opportunity to voice their opinion and relate their experience with a given product. In this thesis, we investigate the possibility to model constructiveness in product review in order to promote the most informative and argumentative customer feedback. We develop a new constructiveness 4-class scale taxonomy based on heuristics and specific categorical criteria. We use this taxonomy to annotate 4000 Amazon customer reviews as our training set, referred to as the Corpus for Review Constructiveness (CRC). In addition to the 4-class constructiveness tag, we include a binary tag to compare modeling performance with previous work. We train and test several computational models such as Bidirectional Encoder Representations from Transformers (BERT), a Stacked Bidirectional LSTM and a Gradient Boosting Machine. We demonstrate our annotation scheme’s reliability with a set of inter-annotator agreement experiments, and show that good levels of performance can be reached in both multiclass setting (0.69 F1 and 57% error reduction over the baseline) and binary setting (0.85 F1 and 71% error reduction). Different features are evaluated individually and in combination. Moreover, we compare the advantages, downsides and performance of both feature-based and neural network models. Finally, these models trained on CRC are tested on out-of-domain data (news article comments) and shown to be nearly as proficient as on in-domain data. This work allows the extension of constuctiveness modeling to a new type of data and provides a new non-binary taxonomy for data labeling.

Full textAbstract:
Context. Successful software product management concerns about developing right software products for right markets at the right time. The product manager, who carries responsibilities of planning, requires but does not always have access to high-quality information for making the best possible planning decisions. The following master thesis concentrates on proposing a solution that supports planning of a software product by means of analytics. Objectives. The aim of the master thesis is to understand potentials of analytics in product planning decisions in a SaaS context. This thesis focuses on SaaS based analytics used for portfolio management, product roadmapping, and release planning and specify how the analytics can be utilized for planning of a software product. Then the study devises an analytics-based method to enable software product planning. Methods. The current study was designed with a mixed methodology approach, which includes the literature review and survey researches as well as case study under the framework of the design science. Literature review was conducted to identify product planning decisions and the measurements that support them. A total of 17 interview based surveys were conducted to investigate the impact of analytics on product planning decisions in product roadmapping context. The result of the interviews ended in an analytics-based planning method provided under the framework of design science. The designed analytics-based method was validated by a case study in order to measure the effectiveness of the solution. Results. The identified product planning decisions were summarized and categorized into a taxonomy of decisions divided by portfolio management, roadmapping, and release planning. The identified SaaS-based measurements were categorized into six categories and made a taxonomy of measurements. The result of the survey illustrated that importance functions of the measurement- categories are not much different for planning-decisions. In the interviews 61.8% of interviewees selected “very important” for “Product”, 58.8% for “Feature”, and 64.7% for “Product healthiness” categories. For “Referral sources” category, 61.8% of responses have valuated as “not important”. Categories of “Technologies and Channels” and “Usage Pattern” have been rated majorly “important” by 47.1% and 32.4% of the corresponding responses. Also the results showed that product use, feature use, users of feature use, response time, product errors, and downtime are the first top measurement- attributes that a product manager prefers to use for product planning. Qualitative results identified “product specification, product maturity and goal” as the effected factors on analytics importance for product planning and in parallel specified strengths and weaknesses of analytical planning from product managers’ perspectives. Analytics-based product planning method was developed with eleven main process steps, using the measurements and measurement scores resulted from the interviews, and finally got validated in a case. The method can support all three assets of product planning (portfolio management, roadmapping, and release planning), however it was validated only for roadmapping decisions in the current study. SaaS-based analytics are enablers for the method, but there might be some other analytics that can assist to take planning decisions as well. Conclusion. The results of the interviews on the roadmapping decisions indicated that different planning decisions consider similar importance for measurement-categories to plan a software product. Statistics about feature use, product use, response time, users, error and downtime have been recognized as the most important measurements for planning. Analytics increase knowledge about product usability and functionality, and also can assist to improve problem handling and client-side technologies. But it has limitations regarding to receiving formed-based customer feedback, handling development technologies and also interpreting some measurements in practice. Immature products are not able to use analytics. To create, remove, or enhance a feature, the data trend provides a wide view of feature desirability in the current or even future time and clarifies how these changes can impact decision making. Prioritizing features can be performed for the features in the same context by comparing their measurement impacts. The analytics-based method covers both reactive and proactive planning.

In some situations firms augment physical products with services related to that product. In other situations the service offered to customers is the primary offering and it is enabled by a product. This paper investigates enterprise resource planning (ERP) software tracking its evolution from predominantly a product with associated services to an offering as a service enabled by the software product. Frameworks have been developed to analyze service offerings. Two such frameworks capture causal relationships to customer value and customer satisfaction. This paper analyzes these frameworks and applies one of them to SAP R/3 ERP software as the offering evolved towards a more pure service offering (product-based). The paper then analyzes the sufficiency and appropriateness of one framework, the service profit chain, to the current offering of the SAP R/3 ERP application service provider (ASP) product, MySAP.com.

Full textAbstract:
The granularity of the information for sharing is one of the essential aspects in project learning. The utilization of information technology has maximised the benefit and extended the scope of sharing at horizontal and vertical aspects, e.g. sharing information between multiple concurrent projects and sharing historic data to new projects. Horizontal information sharing enables the use of common resources in planning and executing projects contained in programmes and portfolio management systems. Vertical information sharing enables a systematic information deposition and dissemination of lessons learned for the knowledge of project management. Information collected throughout a project lifecycle contributes to the project portfolio. Good practises or lessons learnt should be used to guide new projects. Project learning repositories are designed to collect the lesson learnt information and share the information with new projects to better manage them and improve their performance. Current main stream project management methods are process or activity based; making the project portfolio collected and the lesson learnt information granularity process based. Information sharing between projects only happens at the process (activity) level and project level. However, the vast amount of information in between which contains the best practices of producing project's "simple products" (deliverables) are not collected. Portfolios, on the other hand, at each activity level are not easily sharable due to the fact that new technologies, process reengineering and personnel preferences may all affect the chosen activities.

objetivo principal da
ferramenta é permitir que a comunidade de desenvolvimento
de software

de LPSs na produção
de seus sistemas ou partes de seus sistemas sem a
necessidade do
entendimento de modelos e conceitos complexos. A abordagem
implementada
pela ferramenta foi elaborada com base em fundamentos do

(características,
implementação e configuração), a ferramenta permite a
derivação automática de
produtos ou frameworks existentes. O trabalho também define
um conjunto
específico de anotações Java que possibilitam a geração
automática dos
modelos de derivação a partir dos elementos de
implementação da arquitetura
de uma LPS. A plataforma Eclipse e as tecnologia EMF e
openArchitectureWare
foram utilizadas como base para a implementação da
ferramenta. Uma extensão
da ferramenta que atende especificamente aos modelos de
componente Spring
e OSGi, também é proposta nessa dissertação. Tal extensão
permite a
instanciação automática da LPS e aplicações através de
diferentes tipos de
customizações, variando da configuração fina de
propriedades de componentes
até a seleção automática de quais componentes irão compor o
produto final.
Como parte de validação da abordagem, a ferramenta foi
utilizada na derivação
automática de três diferentes estudos de caso: (i) o
framework JUnit; (ii) uma
LPS de jogos J2ME; e (iii) uma aplicação web baseada em
serviços. Diversas

derivation, called
GenArch, which aims to enable the mainstream software
developer community to
use the concepts and foundations of the SPL approach,
without the need to
understand complex concepts or models. The tool approach is
build on top of
model-driven development techniques. It is centered on the
definition of three
models (feature, implementation and configuration models),
which enable the
automatic instantiation of software product lines (SPLs) or
frameworks. A set of
specific Java annotations are also defined to allow
generating automatically many
of the models, based on existing implementations elements
of SPL architectures.
The Eclipse platform, and EMF and openArchitectureWare
technologies are used
as the base for the implementation of the tool. The
dissertation also presents a
GenArch extension that addresses the new abstractions
provided by the Spring
and OSGi component models. Different kinds of
customizations are provided by
this extension varying from fine-grained configuration of
component properties to
the automatic selection of components that will compose the
final product. As
part of the approach validation, the tool was used in the
derivation of three case
studies: (i) JUnit framework; (ii) a J2ME games SPL; (iii)
a service oriented Web
application. Several lessons learned and discussions
resulting from the use of the
tool also are described.

Planning a project with proper considerations of all necessary factors and managing a project to ensure its successful implementation are facing a lot challenges. Initial stage in planning a project is costly, time consuming and usually with poor accuracy on cost and effort predictions. On the other hand, detailed information for previous projects may be buried in piles of archived documents, which make it increasingly difficult to learn from the previous experiences. Current information sharing methods to support project management focus on activity based project operation and processes but lack some granulations on project deliverables, especially when project context and customer requirements are varied. This research develops a product based information sharing (PBIS) framework, which attempts to serve in general project planning and lead to properly and effectively benchmarking and recommending product portfolios for project management purposes. PBIS made contributions in various areas. It introduced a new product based approach to capture and reuse the project information that tackles the issue of information sharing from a very different perspective. The Project Analyser part articulates requirement information at both project and product levels. The analysed results can be used to assist the product based breakdown process which is validated by product refinement rules. The Project Planner part enables project plan to be generated accurately and efficiently through a novel product benchmarking and recommendation mechanism. This mechanism integrated with the strengths of Quartile, Data Envelopment Analysis (DEA) and Analytic Hierarchy Process (AHP) to ensure the right products are selected based on products of which attributes are important for customer criteria during the project planning stage. A novel software system iPAS based on PBIS has been developed to bridge the gap between PBIS main principles and its application, with providing the user with automated planning, monitoring, reports and human resource allocation. PBIS has been trialled with cases studies in two organisations, which clearly shows the business benefits of autonomic project management. It reduced effort to plan new projects and manage project portfolio and decreased estimation bias thereby reducing operational risk. It also automatically benchmarked performance against company best practices. As a result, the PBIS can be used to solve other real world problems in standardised industries such as manufacture, education, medicine, construction and rail industries etc.

Full textAbstract:
Thesis (Ph.D.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2000.<br>Includes bibliographical references (p. 95-97).<br>Platform-based product families have been an effective way for companies to offer increased variety into markets, while containing the resulting complexity of developing large numbers of products. A product platform is the set of resources - components, processes, technologies, and knowledge - that are shared across multiple products offered by a firm. The products derived from that common platform are called the variants, and the set of variants forms a product family. This thesis presents a theoretical basis for modeling the design of platform-based product families, as well as practical implementations based on those models. The problem is formulated as an optimization, where the requirements of the desired variants must be balanced against family objectives, such as maximizing the value of developing the family. A general case is formulated that covers the effects of using a platform-based design on the benefits and investments required to produce the desired family. The problem is then simplified into a two-step optimization approach to apply it to actual design situations for complex products. The first stage considers the technical details of creating feasible product families that satisfy the variants' requirements while optimizing the expected value to the firm. The second stage evaluates the design alternatives generated by the first step, considering the effects of uncertainty during the actual development of the family on its value to the firm. This evaluation is then used to select the most appropriate choice of family design. A case study of the design of multiple NASA exploratory space missions based on alternative telecommunications technology platforms is shown. Applying the approach resulted in several alternative family designs, some of which had not been previously considered viable. The resulting candidate designs were evaluated through the use of decision analysis models developed in this thesis, which calculate the value to the firm of each design. Simulation was then used to evaluate the value of each alternative and its flexibility to changes in uncertain factors during the development process. As a reference, a Pugh-type selection method (a qualitative, multi-criteria approach) was also explored and applied to the example of platform-based spacecraft design.<br>by Javier P.

Full textAbstract:
The gradually increasing competition that occurs in mature markets, pushes the companies to consider new ways of competing. The more mature the market becomes the higher level of competitive fulfillment and edge is needed. E.g. for Scania the dimension high quality was until now considered a competitive advantage, but is currently evolving towards a dimension that is necessary to fulfill to even act within the market. Thus, companies such as Scania have to push their limits everywhere possible across their organization. One way to push the limits of R&D and product development (PD) is, based on this thesis and other work, implementing a simulation based product development (SBPD) process. The aim of this thesis has been, by applying a quality function deployment (QFD) model, to show the influence a SBPD process can have on increased competitiveness. By combining published literature within the field with empirical results mostly gained from interviews, nine components representing a SBPD process could be found. These components were characterized in the following categories: IT-infrastructure, design, model & test, and organizational. Depending on the level of fulfillment of these components the SBPD process is more or less implemented within the company. The two components that are considered the most important for Scania in terms of both increased competitiveness and a possible transition towards a SBPD process are Virtual representa-tion of the product and the process throughout the whole PD process and A model driven/model based approach. The work of this thesis has also shown, in correlations with previous published literature, that a SBPD process can significantly decrease the lead-time and cost of development, and at the same time increase the knowledge about the product and the process. The research has also shown that a SBPD process can considerably improve both the internal and the external collaboration. However attaining such a process where these competitive advantages can be gained affects the whole organization, the way development is performed and also the way resources are used. A fully implemented SBPD process has been shown to positively impact the following competitive dimensions; Frequency of product introductions, Lead-time of development, PD process flexibility, Degree of innovation, Customization of the offer, Collaboration with internal and external partners, Knowledge about products and processes, R&D cost, manufacturing cost, Focus on customers operational economics, Product quality, Product safety and Focus on environmental sustainability of the product & the processes. But, to get a positive impact on all these dimensions the components representing a SBPD process must be implemented and applied. Furthermore, this thesis also provides a framework for other companies to evaluate the impact a SBPD process can have on their competitiveness. The analysis model aims to guide companies that want to adopt a SBPD process. The framework can indicate how a SBPD process would impact the firm's competitive strategy. But also to provide guidance to which components that would be more important to implement in order to reach a competitive SBPD process.<br>Den gradvis ökande konkurrens som uppstår på mogna marknader driver företagen att finna nya sätt att konkurrera. Ju mer mogen marknaden blir desto högre blir kraven på konkurrens. För Scania har faktorn hög kvalitet tills nu betraktas som en konkurrensfördel, men utveckling sker istället mot att det kommer att vara en faktor som är nödvändig att uppfylla för att ens kunna agera på marknaden. Företag som Scania måste således utvecklas över hela organisationen. Ett sätt att tänja på gränserna för FoU och produktutveckling (PD) är, baserat på detta arbete och annan tidigare forskning, att genomföra en förändring mot en simulering baserad produktutvecklings-process (SBPD). Syftet med detta examensarbete har varit att, genom att tillämpa en quality function deployment (QFD) modell, visa effekten en SBPD-process kan ha på ökad konkurrenskraft. Genom att kombinera tidigare publicerad litteratur inom området med empiriska resultat, mestadels insamlat genom intervjuer, kunde nio komponenter som utgör en SBPD-process finnas. Dessa komponenter karakteriserades i följande kategorier: IT-infrastruktur, design, modellera och testa och organisatorisk. Beroende på graden av uppfyllnad på dessa komponenter blir den SBPD-processen mer eller mindre implementerad inom företaget. De två komponenterna som anses viktigast för Scania i form av både ökad konkurrenskraft och en eventuell övergång till en SBPD-process är Virtuell representation av produkten och processen genom hela PD-processen och Ett modellbaserat/ modelldrivet arbetssätt används. Arbetet har också visat i korrelation med tidigare publicerad litteratur, att en SBPD-process kommer att minska ledtiden och kostnaden för utveckling avsevärt och samtidigt öka kunskapen om produkten och processen. Denna studie har också visat att en SBPD-process kan förbättra både interna och externa samarbeten. Men att uppnå en sådan process där dessa konkurrens-fördelar kan vinnas kommer att påverka hela organisationen, det sätt som utveckling utförs på och också hur resurserna används. En fullt implementerad SBPD-process har visat positivt påverkan följande konkurrens faktorer; frekvens av produktlanseringar, ledtiden för utveckling, PD-processflexibilitet, innovationsgrad, anpassning av erbjudandet, samarbete med interna och externa partners, kunskap om produkter och processer, FoU kostnader, tillverkningskostnad, fokus på kundernas driftsekonomi, produktkvalitet, produktsäkerhet och miljöpåverkan av både produkten och processen. För att få en positiv inverkan på alla dessa faktorer måste alla komponenter som utgör en SBPD-process implementeras och tillämpas. Dessutom så presenteras även ett ramverk för andra företag att utvärdera effekterna en SBPD-process skulle ha på deras konkurrenskraft. Analysmodellen syftar till att vägleda företag som vill övergå till en SBPD-process. Ramverket kan ange hur en SBPD-process skulle kunna påverka företagets konkurrensstrategi men också ge vägledning om vilka komponenter som kan vara viktigare att börja implementera för att nå en konkurrenskraftig SBPD-process.

Full textAbstract:
Multi-label classification consists of learning a function that is capable of mapping an object to a set of relevant labels. It has applications such as the association of genes with biological functions, semantic classification of scenes and text categorization. Traditional classification (i.e., single-label) is therefore a particular case of multi-label classification in which each object is associated with exactly one label. A successful approach to constructing classifiers is to obtain a probabilistic model of the relation between object attributes and labels. This model can then be used to classify objects, finding the most likely prediction by computing the marginal probability or the most probable explanation (MPE) of the labels given the attributes. Depending on the probabilistic models family chosen, such inferences may be intractable when the number of labels is large. Sum-Product Networks (SPN) are deep probabilistic models, that allow tractable marginal inference. Nevertheless, as with many other probabilistic models, performing MPE inference is NP- hard. Although, SPNs have already been used successfully for traditional classification tasks (i.e. single-label), there is no in-depth investigation on the use of SPNs for Multi-Label classification. In this work we investigate the use of SPNs for Multi-Label classification. We compare several algorithms for learning SPNs combined with different proposed approaches for classification. We show that SPN-based multi-label classifiers are competitive against state-of-the-art classifiers, such as Random k-Labelsets with Support Vector Machine and MPE inference on CutNets, in a collection of benchmark datasets.<br>A classificação Multi-Rótulo consiste em aprender uma função que seja capaz de mapear um objeto para um conjunto de rótulos relevantes. Ela possui aplicações como associação de genes com funções biológicas, classificação semântica de cenas e categorização de texto. A classificação tradicional, de rótulo único é, portanto, um caso particular da Classificação Multi-Rótulo, onde cada objeto está associado com exatamente um rótulo. Uma abordagem bem sucedida para classificação é obter um modelo probabilístico da relação entre atributos do objeto e rótulos. Esse modelo pode então ser usado para classificar objetos, encon- trando a predição mais provável por meio da probabilidade marginal ou a explicação mais provavél dos rótulos dados os atributos. Dependendo da família de modelos probabilísticos escolhidos, tais inferências podem ser intratáveis quando o número de rótulos é grande. As redes Soma-Produto (SPN, do inglês Sum Product Network) são modelos probabilísticos profundos, que permitem inferência marginal tratável. No entanto, como em muitos outros modelos probabilísticos, a inferência da explicação mais provavél é NP-difícil. Embora SPNs já tenham sido usadas com sucesso para tarefas de classificação tradicionais, não existe investigação aprofundada no uso de SPNs para classificação Multi-Rótulo. Neste trabalho, investigamos o uso de SPNs para classificação Multi-Rótulo. Comparamos vários algoritmos de aprendizado de SPNs combinados com diferentes abordagens propostos para classi- ficação. Mostramos que os classificadores Multi-Rótulos baseados em SPN são competitivos contra classificadores estado-da-arte, como Random k-Labelsets usando Máquinas de Suporte Vetorial e inferência exata da explicação mais provavél em CutNets, em uma coleção de conjuntos de dados de referência.

Full textAbstract:
The work presented in this thesis is concerned with algebraic coding theory, with a particular focus on space-time codes constructed from crossed product algebras. This thesis is divided into three parts. In the first part we will present a method for constructing codes from crossed product algebras and derive bounds on their performance. The second part concerns itself with codes constructed from cyclic algebras. Finally in the third part, constructions based on biquadratic crossed product algebras are considered. It is well known that two important design criteria in the construction of spacetime codes are the rank criterion and the determinant criterion. The rank criterion is closely linked to the notion of fully diverse codes. Constructing codes that are fully diverse led to the study of codes based on division algebras. To give explicit constructions of codes, central simple algebras were considered and in particular crossed product algebras. In this thesis we derive bounds on the minimum determinant of codes constructed from crossed product algebras. A lot of work has focused on constructing codes based on cyclic division algebras. The well known perfect space-time block codes are codes that satisfy a variety of coding constraints that make them very efficient for coding. We consider the performance of these codes and prove that the best known examples are optimal with respect to the coding gain. Finally we consider codes based on biquadratic crossed product algebras, where the Galois group of the underlying field extension is isomorphic to the Klein fourgroup. It has been shown that these codes can satisfy a large number of coding criteria and exhibit very good performance. We prove the optimality of the best known code

Full textAbstract:
Internet est une immense source de données non structurées dont l'extraction et l'analyse devient un enjeu majeur. Ces informations peuvent être plus qu'utiles à des consommateurs et des fabricants dans leur processus de prise de décision quant à un produit. Dans ce contexte, l'exploitation de telles information se révèle être une tâche très difficile. De nombreuses méthodes d'évaluation de produits existent à l'heure actuelle, utilisant principalement les notes et les commentaires disponibles sur Internet. Cependant, ces méthodes rencontrent vite des limites et ne sont donc pas en mesure de répondre aux besoins et aux exigences des clients ou des fabricants. Par exemple, les méthodes existantes d'analyse de sentiments, qui classent les opinions des clients sur un produit à l’aide de leur polarité, ne sont pas en mesure de déterminer le contexte du mot dans une phrase avec précision, ce qui biaise fortement leurs résultats. De plus, les méthodes de traitement des négations utilisées, qui déterminent les sentiments exprimées par les clients dans leur commentaires, ne sont pas en mesure de traiter tous les types de négation, ne considèrent pas non plus toutes les exceptions où les négations se comportent différemment. De même, les modèles existants d'estimation de réputation de produits sont basés sur une source unique, et donc peu robuste aux fausses évaluations ou aux évaluations biaisées, ne sont pas en mesure de refléter les opinions récentes. Ils ne permettent pas aux utilisateurs d'évaluer le produit au regard de critères spécifiques, et ainsi ne fournissent pas une estimation précise. D'autre part, les systèmes de réputation évaluant des produits fonctionnent de manière centralisée, entraînant des problèmes de robustesse et des facilités de manipulation, voire de falsification, d'informations, ces approches ne convenant pas à résoudre un problème aussi complexe. Cette thèse propose des modèles et des méthodes d'évaluation de la réputation dédiées aux produits, fonctionnant à partir des données disponibles sur Internet, et visant à fournir des informations précises aux consommateurs et aux fabricants, les appuyant dans leur prise de décision. Ces méthodes concernent i) l'extraction des données d'évaluation des produits à partir de plusieurs sources; ii) une analyse sémantique des évaluations des clients pour déterminer si les opinions exprimées sur chacune des caractéristiques d'un produit sont positives ou négatives; iii) le calcul des différentes valeurs de réputation d'un produit, tout en considérant différents critères d'évaluation, et iv) enfin, le retour des résultats aux consommateurs ou aux fabricants afin de les aider dans leur prise de décisions. Cette thèse contribue à trois principaux domaines de recherche à savoir i) l'analyse des sentiments exprimées quant aux caractéristiques d'un produit, comprenant une méthode de désambiguïsation du sens des mots ainsi qu'une prise en compte plus fine des négations pour améliorer la performance de l'analyse de sentiments selon différents niveaux; ii) les modèles d'évaluation de la réputation d'un produit, basé sur un modèlemathématique calculant plusieurs valeurs de réputation pour une évaluation d'un produit selon différents critères et enfin iii) une architecture multi-agents robuste, facilitant le déploiement et la parallélisation des tâches. Sur Internet, la plupart des opinions sur des produits sont de nature textuelle, comme par exemple les avis des consommateurs. Afin d'analyser de tels commentaires, une méthode d'analyse de sentiments exprimés ciblant spécifiquement les caractéristiques d'un produit a été développée. Une méthode de désambiguïsation identifiant le sens des mots selon leur contexte tout en déterminant leur polarité a enrichi le processus, qui fût complété par une méthode d'analyse fine des négations, déterminant les séquences de mots affectées par chaque type de négation<br>The extraction of unstructured data from the Web and to analyzing them in order to determine useful information which can be used by customers and manufacturers to make decisions about product is a challengeable task. There are some existing techniques to evaluate products based on the ratings and product reviews posted on the Web. However, all these techniques have some inherent issues and limitations and therefore not able to fulfill the needs and requirements of both customer and manufacturer. For instance, the existing sentiment analysis methods (which classify the opinions in customer reviewsabout a product as positive or negative) are not able to determine the context of word in a sentence accurately. In addition, negation handling methods adopted while determining the sentiment are not able to deal with all types of negations and they also do not consider all exceptions where negations behave differently. Similarly, the existing product reputation models are based on single source, not robust to false and biased ratings, not able to reflect the recent opinions, do not allow users to evaluate product on different criteria, and also do not provide a good estimation accuracy. On the other hand, the existingproduct reputation systems are centralized which has issues such as single point of failure, easy to falsify evaluation information and not suitable approach to solve a complex problem. This thesis proposes methods and techniques for evaluating product reputation based on data available on the Web and to provide valuable information to customers and manufacturers for decision making. These methods perform the following tasks: 1) extract product evaluation data from multiple Web sources 2) analyze product reviews in order to determine that whether opinions about product features in customer reviews are positive or negative, 3) computes different product reputation values while considering different evaluation criteria, and 4) finally the results are provided to customers and manufacturers in order to make decisions. This thesis contributes in three main research areas i.e. 1) feature level sentiment analysis, 2) product reputation model and 3) multiagent architecture. First, a word sense disambiguation and negation handling methods are proposed in order to improve the performance of feature level sentiment analysis. Second, a novel mathematical model is proposed which computes several reputation values in order to evaluate product based on different criteria. Finally, multiagent architecture for review analysis and product evaluation is proposed. Huge amount of the product evaluation data on the Web is in textual form (i.e. product reviews). In order to analyze product reviews to evaluate product we propose a feature level sentiment analysis method which determines the opinions about different features of a product. A word sense disambiguation method is introduced which identify the sense of words according to the context while determining the polarity. Inaddition, a negation handling method is proposed which determine the sequence of words affected by different types of negations. The results show that both word sense disambiguation and negation handling methods improve the overall accuracy of feature level sentiment analysis. A multi-source product reputation model is proposed where informative, robust and strategy proof aggregation methods are introduced to compute different reputation values. Sources from which reviews are extracted may not be creditable hence a source credibility measuring method is proposed in order to avoid malicious web sources. In addition, suitable decay principles for product reputation are also introduced in order to reflect the newest opinions about product quickly. The model also considers several parameters such as reviewer expertise, rating trustworthiness, time span of ratings, reviewer age, sex and location in order to evaluate product in different ways

Full textAbstract:
Requirements from the market on customer responsiveness and pressure on the environmental profiles of companies, both internally and externally, are challenging companies to amend their processes in all possible aspects in order to stay competitive. For product development companies, the challenges often lie in developing and delivering products rapidly, customized and meeting the set requirements. For highly customized products, mass customization is a term describing a company setting in which products meet each customer’s individual requirements but are still produced and delivered at near mass-production efficiency. The concept of mass customization is becoming a prerequisite for the survival of companies within this niche. For more complex engineering products, the complexity increases as new technology is introduced, which needs to be integrated to increase the product’s performance at a rapid pace. Also for complex products, the level of customization is increasing, which motivates the support of tools enabling an increase in customization. In both mass customized and complex products, the obstacles to overcome are the repetitive resource inefficient work, knowledge capture and reuse, uncoordinated processes, and a high number of iterations between departments within the company. This often boils down to the well-established so-called design paradox describing the lack of knowledge about a product and process in the early stages of design, where the design freedom is still high. As knowledge increases throughout the process, the design freedom in contrast shrinks, and the costs of changes increase exponentially. Design automation, design optimization and the use of configurators are all methods used to reduce repetitive work, increase and capture knowledge, and integrate the product development process. This thesis presents how configurators based on optimization can be used and integrated into the product development process of engineering intensive configurable products and components, such as engineer-to-order (ETO) products. Design automation and design optimization have been identified as key building blocks to extend the use of configurators. This has been done in two different application cases within two different research projects, to evaluate how these configurator systems may be modeled and utilized. The first application case concerns the automation of hose routing in vehicles and the second application case concerns spiral staircases intended for mass customization.

Full textAbstract:
This thesis examines the "state of the art" of product innovation in new technology In the UK. The roles in innovation attributed to small and large firms are examined. Growing attention is being focused upon the small firm sector as a seedbed for Innovation and government policy has been changing to encourage the entrepreneurial new technology based firm (NTBF). The novel perspective of this research results from working in such a firm. It provides a longitudinal study of the management of innovation in conjunction with the corporate strategy of the firm. Given that the researcher was a participant and observer in the firm studied, the research is akin to action research in methodology but is better described as grounded theory. Theoretical concepts are drawn from the prescriptive literature describing corporate strategy, and from the empirical literature which has evaluated new product success and failure. Models of the Innovation process are discussed and appropriate strategies and reasons for product innovation failure in NTBFs are described. The strategy, structure and new product development progress of the company are examined, using both the researcher's observations and company documents. This provides information on the methods and practices adopted for product innovation in a NTBF. The thesis analyses the performance of the firm In terms of product innovation. The models and strategies derived from the literature are then tested in the light of the experience of the company. Conclusions are drawn regarding strategies for innovation in NTBFs and about the innovation process in general. The importance of a NTBF adopting a synergistic strategy is shown. Links are established between the existence of synergy in the strategy and coupling in the management of innovation. Innovation is shown to be a laterally interdisciplinary exercise and therefore the "pipeline model" Is criticised. Finally a set of guidelines Is produced for the managers of NTBFs.

Actuellement, de nombreuses entreprises ont besoin de construire des versions\variantes légèrement différentes d'un même système. Ces versions partagent des points communs et des différences, le tout pouvant être géré à l'aide d'une approche ligne de produits (SPL). L'objectif principal d'une SPL est d'exploiter la personnalisation de masse, dans laquelle les produits sont réalisés pour répondre aux besoins spécifiques de chaque client. Pour répondre à ce besoin de personnalisation, les systèmes doivent être étendus de manière efficace, ou modifiés, configurés pour être utilisé dans un contexte particulier. Une approche encourageante consiste à connecter l'approche MDE (l'ingénierie dirigée par les modèles) à l'approche SPL – les SPL basées sur les modèles (MSPL). L'espace de conception, l'environnement du système logiciel que l'on construit (i.e., l'ingénierie du domaine) d'une MSPL est extrêmement complexe à gérer pour un ingénieur. Tout d'abord, le nombre possible des produits d'une MSPL est exponentielle au nombre d'éléments ou de décisions exprimé dans le modèle de variabilité. Ensuite, les modèles de produits dérivés doivent être conformes à de nombreuses règles liées au domaine métier mais aussi aux langages de modélisation utilisés. Troisièmement, le modèle de réalisation qui relie un modèle de variabilité et un modèle de base peut être très expressif. En plus, il faut ajouter que les ingénieurs système utilisent différents langages de modélisation dédiés dans le cadre de projets pour la réalisation de systèmes critiques. Nos contributions sont basées sur le fait qu'une solution générique, pour tous les domaines, et qui dérive des modèles corrects n'est pas réaliste, surtout si on prend en considération le contexte des systèmes complexes décrits précédemment. Nous proposons une approche indépendante du domaine pour générer des contre-exemples de MSPLs, révélant des erreurs de conceptions de modèles et supportant les parties prenantes à construire de meilleures MSPLs et des mécanismes de dérivation plus efficaces. Plus précisément, la première et principale contribution de la thèse est un processus systématique et automatisé, basé sur CVL (common variability language), pour la recherche aléatoire de contre-exemples de MSPL dans un langage donné. La seconde contribution de la thèse est un étude sur les mécanismes pour étendre la sémantique des moteurs de dérivation, offrant une approche basée sur des modèles à fin de personnaliser leurs sémantique opérationnelle. Dans la troisième contribution de la thèse, nous présentons une étude empirique à large échelle sur le langage Java en utilisant notre approche générative. La quatrième et dernière contribution de la thèse est une méthodologie pour intégrer notre travail dans une organisation qui cherche à mettre en œuvre les lignes de produit logiciels basées sur des modèles pour l'ingénierie des systèmes<br>Systems Engineering is a complex and expensive activity in several kinds of companies, it imposes stakeholders to deal with massive pieces of software and their integration with several hardware components. To ease the development of such systems, engineers adopt a divide and conquer approach : each concern of the system is engineered separately, with several domain specific languages (DSL) and stakeholders. The current practice for making DSLs is to rely on the Model-driven Engineering (MDE. On the other hand, systems engineering companies also need to construct slightly different versions/variants of a same system; these variants share commonalities and variabilities that can be managed using a Software Product Line (SPL) approach. A promising approach is to ally MDE with SPL – Model-based SPLs (MSPL) – in a way that the products of the SPL are expressed as models conforming to a metamodel and well-formedness rules. The Common Variability Language (CVL) has recently emerged as an effort to standardize and promote MSPLs. Engineering an MSPL is extremely complex to an engineer: the number of possible products is exponential; the derived product models have to conform to numerous well- formedness and business rules; and the realization model that connects a variability model and a set of design models can be very expressive specially in the case of CVL. Managing variability models and design models is a non-trivial activity. Connecting both parts and therefore managing all the models is a daunting and error-prone task. Added to these challenges, we have the multiple different modeling languages of systems engineering. Each time a new modeling language is used for developing an MSPL, the realization layer should be revised accordingly. The objective of this thesis is to assist the engineering of MSPLs in the systems engineering field, considering the need to support it as earlier as possible and without compromising the existing development process. To achieve this, we provide a systematic and automated process, based on CVL, to randomly search the space of MSPLs for a given language, generating counterexamples that can server as antipatterns. We then provide ways to specialize CVL’s realization layer (and derivation engine) based on the knowledge acquired from the counterexamples. We validate our approach with four modeling languages, being one acquired from industry; the approach generates counterexamples efficiently, and we could make initial progress to increase the safety of the MSPL mechanisms for those languages, by implementing antipattern detection rules. Besides, we also analyse big Java programs, assessing the adequacy of CVL to deal with complex languages; it is also a first step to assess qualitatively the counterexamples. Finally, we provide a methodology to define the processes and roles to leverage MSPL engineering in an organization

Full textAbstract:
<p> System design at the component level seeks to construct a design trade space of alternate solutions comprising mapping(s) of system function(s) to physical hardware or software product components. The design space is analyzed to determine a near-optimal next-level allocated architecture solution that system function and quality requirements. Software product components are targeted to increasingly complex computer systems that provide heterogeneous combinations of processing resources. These processing technologies facilitate performance (speed) optimization via algorithm parallelization. However, speed optimization can conflict with electrical energy and thermal constraints. A multi-disciplinary architecture analysis method is presented that considers all attribute constraints required to synthesize a robust, optimum, extensible next-level solution. This paper presents an extensible, executable model-based architecture attribute framework that efficiently constructs a component-level design trade space. A proof-of-concept performance attribute model is introduced that targets single-CPU systems. The model produces static performance estimates that support optimization analysis and dynamic performance estimation values that support simulation analysis. This model-based approach replaces current architecture analysis of alternatives spreadsheet approaches. The capability to easily model computer resource alternatives that produces attribute estimates improves design space exploration productivity. Performance estimation improvements save time and money through reduced prototype requirements. Credible architecture attribute estimates facilitate more informed design tradeoff discussions with specialty engineers. This paper presents initial validation of a model-based architecture attribute analysis method and model framework using a single computation thread application on two laptop computers with different CPU configurations. Execution time estimates are calibrated for several data input sizes using the first laptop. Actual execution times on the second laptop are shown to be within 10 percent of execution time estimates for all data input sizes.</p><p>

There exists an increasing evidence of benefits with involving suppliers in a new product development activity in the mass production companies. Challenges such as, reduction of a product life cycle, technological uncertainties, and increased cost of R&D activity have made it necessary to extend a new product development activity, beyond the firm’s boundary. However, in a project based industries this trend is not predominant and importance of innovation and suppliers, applies to this industry also. Hence, Objective of the thesis is to establish a framework for involving suppliers for a project based industry. The qualitative research makes use of extensive literature within the field, product development, innovation and project based industry and supplier involvement in product development. Several interviews were carried out for collection the empirical data at the case company, which is a project based organization. Required framework, a result of the thesis is achieved through an extensive empirical analysis.The results show that a value of innovation is different between the project based industries and the mass production industries and it is perceived differently. However, innovation is equally important for a project based industry and it has a potential to include innovation within its processes. On this regard, several challenges and innovation promoting elements have been identified. Project management techniques and disruption in the knowledge transfer are some of the impediments for innovation within project based industries. The thesis provides the suggested framework to overcome these challenges and increase innovation in a project based industry and involves suppliers in its innovative and development activities.

Full textAbstract:
Information is an important part of the manual assembly process. Information provides the user with the means to fulfil assembly tasks so that the right quality as well as high productivity are accomplished. This thesis addresses issues connected to information and information use in a modern manual assembly environment, and how these issues affect human operators, quality and productivity. The overall objectives of the research were to gain further knowledge on how attention affects the internal reject rate, to investigate these phenomena in industrial and laboratory environments and finally to propose a suitable evaluation method to be utilised at the design stage of an information system. Studies were performed with the purpose of investigating how the assembly personnel were affected by the information and how it affected quality and productivity. The studies were performed in an assembly plant and in the laboratory. Quantitative data collection included 10 days and nights of production where the information impact on quality was investigated. Connected to this study was a qualitative survey performed among 171 persons from the assembly personnel. The laboratory study took place during three days, approximately eight hours each day. It involved 30 persons, all experienced assembly workers from the reference assembly plant. The focus of this study was how information affected the personnel and thereby the productivity. The findings revealed that information affected the quality rates and productivity and that this can be linked to how the information is presented as well as when the information is presented. It was possible to link these findings to the outcome of a successful information search process, and to conclude that a use of an evaluation method or work process during the product lifecycle could have made it possible to avoid some of the problems connected to the information presentation. This is the basis for a proposed pragmatic evaluation method. The method was tested as a support system during the design of a prototype user interface to be used at the pilot plant. The major contribution of this research is the connection between attention and quality as well as the connection between attention and productivity. Knowledge regarding the importance of presenting the information at the right time must also be regarded as an important and proven contribution.

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2000.<br>Includes bibliographical references (p. 94).<br>An experimental study was carried out on the applications of four information-based product development tools supported by the MIT Center of Innovation in Product Development (CIPD). The names of these tools are Assembly Designer, Distributed Object-based Modeling Environment (DOME), Design Structure Matrix (DSM) and KCTool. Sample applications of these currently independent software programs were constructed based on data from a product development case provided jointly by the Naval Research Laboratory and the Lockheed Martin Tactical Defense Systems. Possible tool interactions were investigated and potential integration opportunities were explored utilizing an integration framework commonly employed in the software development industry. The result of the study suggests that the tools can be integrated according to four relationships: Presentation, Data, Control, and Process. Some of the proposed integration opportunities include the implementation of a common user interface and a service exchange system through DOME, the consolidation of data format between Assembly Designer and KCTool, and the support of a program execution order starts with DSM, DOME, Assembly Designer, and ends with KCTool. Future opportunities in this tool integration research include the exploration of tool capabilities with different sets of industrial data and the addition of other tools into the research, such as portfolio management and customer data collection tools.<br>by Tze Ho Lee.<br>S.M.

Full textAbstract:
Distributed system simulation can increase performance, re-usability and modularity in model-based product development. This thesis investigates four aspects of distributed simulation: multi-threaded simulations, simulation tool coupling, distributed equation solvers and parallel optimization algorithms. Multi-threaded simulation makes it possible to split up the workload over several processing units. This reduces simulation time, which can save both time and money during the product development cycle. The transmission line element method (TLM) is used to decouple models to independent sub-models. Different simulation tools are suitable for different problems. Tool coupling makes it possible to use the best suited tool for simulating each part of the whole product. Models from different tools can then be coupled into one aggregated simulation model. An emerging standard for tool coupling is the Functional Mock-up Interface (FMI). It is investigated how this can be used in conjunction with TLM. Equation-based object-oriented languages (EOOs) are becoming increasing popular. A logical approach is to let the equation solvers maintain the same structure that was used in the modelling process. Methods for achieving this using TLM and FMI are implemented and evaluated. In addition to parallel simulations, it is also possible to use parallel optimization algorithms. This introduces parallelism on several levels. For this reason, an algorithm for profile-based multi-level scheduling is proposed.

Previous issue date: 2018-02-15<br>Contexto: Técnicas de verificação têm sido aplicadas para garantir que sistemas de software atinjam níveis de qualidade desejados e atenda a requisitos funcionais e nãofuncionais. Entretanto a aplicação dessas técnicas de verificação em linhas de produto de software é desafiador devido à explosão combinatorial do número de produtos que uma linha de produtos pode instanciar. As técnicas atuais de verificação de linhas de produtos utilizam model checking simbólico e informações sobre variabilidade para otimizar a análise, mas ainda apresentam limitações que as tornam onerosas ou inviáveis. Em particular, as técnicas de verificação do estado da arte para análise de confiabilidade em linhas de produto são enumerativas o que dificulta a aplicabilidade das mesmas devido à explosão combinatorial do espaço de configurações. Objetivo: Os objetivos dessa tese são os seguintes: (a) apresentar um método eficiente para calcular a confiabilidade de todas as configurações de uma linha de produtos de sotware composicional ou anotacional à partir de seus modelos comportamentais UML, (b) fornecer uma ferramenta que implemente o método proposto e, (c) relatar um estudo empírico comparando o desempenho de diferentes estratégias de análises de confiabilidade para linhas de produto de software. Método: Esse trabalho apresenta uma nova estratégia de análise feature-family-based para calcular a confiabilidade de todos os produtos de uma linha de produtos de software (composicional ou anotacional). O passo feature-based da estratégia divide os modelos comportamentais em unidades menores para que essas possam ser analisadas mais eficientemente. O passo family-based realiza o cálculo de confiabilidade para todas as configurações de uma só vez ao avaliar as expressões de confiabilidade em termos de uma estrutura de dados variacional adequada. Resultados: Os resulstados empíricos mostram que a estratégia feature-family-based para análise de confiabilidade supera, em termos de tempo e espaço, quatro outras estratéfias de análise do estado da arte (product-based, family-based, feature-product-based e family-product-based) para a mesma propriedade. No contexto da avaliação e em comparação com as outras estratégias, a estratégia feature-family-based foi a única capaz de escalar a um crescimento do espaço de configuração da ordem de 220. Conclusões: A estratégia feature-family-based utiliza e se beneficia das estratégias feature- e family- ao domar o crescimento dos tamanhos dos modelos a serem analizados e por evitar a enumeração de produtos inerentes a alguns métodos de análise do estado da arte.<br>Context: Verification techniques are being applied to ensure that software systems achieve desired quality levels and fulfill functional and non-functional requirements. However, applying these techniques to software product lines is challenging, given the exponential blowup of the number of products. Current product-line verification techniques leverage symbolic model checking and variability information to optimize the analysis, but still face limitations that make them costly or infeasible. In particular, state-of-the-art verification techniques for product-line reliability analysis are enumerative which hinders their applicability, given the latent exponential blowup of the configuration space. Objective: The objectives of this thesis are the following: (a) we present a method to eciently compute the reliability of all configurations of a compositional or annotationbased software product line from its UML behavioral models, (b) we provide a tool that implements the proposed method, and (c) we report on an empirical study comparing the performance of dierent reliability analysis strategies for software product lines. Method: We present a novel feature-family-based analysis strategy to compute the reliability of all products of a (compositional or annotation-based) software product line. The feature-based step of our strategy divides the behavioral models into smaller units that can be analyzed more eciently. The family-based step performs the reliability computation for all configurations at once by evaluating reliability expressions in terms of a suitable variational data structure. Results: Our empirical results show that our feature-family-based strategy for reliability analysis outperforms, in terms of time and space, four state-of-the-art strategies (product-based, family-based, feature-product-based, and family-product-based) for the same property. In the evaluation’s context and in comparison with the other evaluation strategies, it is the only one that could be scaled to a 220-fold increase in the size of the configuration space. Conclusion: Our feature-family-based strategy leverages both feature- and familybased strategies by taming the size of the models to be analyzed and by avoiding the products enumeration inherent to some state-of-the-art analysis methods.

Previous issue date: 2013<br>Software testing is recognized as a fundamental activity for assuring software quality. Furthermore, testing is also recognized as one of the most time consuming and expensive activities of software development process. A diversity of testing tools has been developed to support this activity, including tools for Model-based Testing (MBT). MBT is a testing technique to automate the generation of testing artifacts from the system model. This technique presents several advantages, such as, lower cost and less effort to generate test cases. Therefore, in the last years a diversity of commercial, academic, and open source tools to support MBT has been developed to better explore these advantages. In spite of the diversity of tools to support MBT, most of them have been individually and independently developed from scratch based on a single architecture. Thus, they face difficulties of integration, evolution, maintenance, and reuse. In another perspective, Software Product Lines (SPL) offers possibility of systematically generating software products at lower costs, in shorter time, and with higher quality. The main contribution of this Ph. D thesis is to present a SPL for testing tools that support MBT (PLeTs) and an automated environment to support the generation of these tools (PlugSPL). Furthermore, our strategy was initially applied to generate some MBT testing tools which were applied in two examples of use performed in collaboration of an IT company. Based on the feedback from the examples of use we can infer that SPL can be considered a relevant approach to improve productivity and reuse during generation of MBT testing tools. Moreover, we also performed an experimental study carried out to evaluate the effort to use an MBT tool derived from our SPL to generate test scripts and scenarios. Thus, the results point out that the effort to generate test scripts, when compared with a Capture and Replay based tool, was reduced considerably.<br>O teste de software é uma atividade fundamental para garantir a qualidade de software. Além disso, teste de software é uma das atividades mais caras e demoradas no processo de desenvolvimento de software. Por esta razão, diversas ferramentas de teste foram desenvolvidas para apoiar esta atividade, incluindo ferramentas para Teste Baseado em Modelos (TBM). TBM é uma técnica de teste para automatizar a geração de artefatos de teste a partir de modelos do sistema. Esta técnica apresenta diversas vantagens, tais como, menor custo e esforço para gerar casos de teste. Por este motivo, nos últimos anos, diversas ferramentas para TBM foram desenvolvidas para melhor explorar essas vantagens. Embora existam diversas ferramentas TBM, a maioria delas tem o seu desenvolvimento baseado em um esforço individual, sem a adoção de técnicas de reuso sistemático e com base em uma única arquitetura, dificultando a integração, evolução, manutenção e reutilização dessas ferramentas. Uma alternativa para mitigar estes problemas é adotar os conceitos de Linhas de Produto de Software (LPS) para desenvolver ferramentas de TBM. LPS possibilitam gerar sistematicamente produtos a custos mais baixos, em menor tempo e com maior qualidade. A principal contribuição desta tese de doutorado é apresentar uma LPS de ferramentas de teste que suportam TBM (PLeTs) e um ambiente automatizado para apoiar a geração dessas ferramentas (PlugSPL). Além disso, esta tese apresenta uma abordagem para gerar ferramentas para TBM, que foram aplicadas em dois exemplos de uso. Com base nos resultados obtidos nos exemplos de uso, podemos inferir que LPS pode ser considerada uma abordagem relevante para melhorar a produtividade e o reuso durante a geração de ferramentas de TBM. Além disso, também foi realizado um estudo experimental com o objetivo de avaliar o esforço para se utilizar uma ferramenta derivada da PLeTs para geração de scripts de teste. Os resultados apontaram que o esforço para gerar scripts de teste foi reduzido consideravelmente, quando comparado com a uma ferramenta de Capture and Replay.

碩士<br>國立臺北大學<br>資訊管理研究所<br>93<br>Due to the rapid development of e-Commerce, the Internet users can search product information easy through the online store in accordance with their own interests. When the users browse the product online, the inappropriate sort make the users hard to find the target goods they need. How to classify the products efficiently and properly is now an important issue for online store managers. This study proposed an automatic product classification mechanism classify products according to similarities. The similarities are calculated according to products’ specifics. This mechanism assigns all products into the proper groups. The online store websites may display products according to this obtain groups data and similarities of all products. Once a new product record is inserted into the database, all products in the database including the new one will be re-classified according to the automatic product classification mechanism this study proposed, and the similarities and groups would also be re-new. This can make products classification automatically. In the traditional classification methods, the users have to leave their personal information and use an account/password if the websites hope to sort the product messages according to customers’ preference. Nowadays, the Internet user pays more attention on privacy and information security, consumers may be unwilling to leave their personal information. However, the automatic product classification mechanism this study proposed let users could choice the product classification they prefer without providing personal information. Users pick one of the representative product items and then all the other products would sort according to the similarities of products to this selected item. Since that the products are sort according to consumers’ preference, the purchase rate might be raised. With this automatic merchandise clustering system, online store managers would not be worried about how to classify and how to sort the new added products. All they need to do is to put all the specifications of the new product into the database correctly and the automatically classification mechanism would do all the others.

Tese de doutoramento em Informática<br>Two main problems have been hindering the adoption of source code metrics for quality evaluation in industry: (i) the difficulty in doing a qualitative interpretation of measurements; and (ii) the inability of summarizing measurements into a single meaningful value that captures quality at the level of overall system.
This dissertation proposes an approach based on two methods to solve these problems using thresholds derived from an industrial benchmark.
The first method categorizes measurements into different risk areas using risk thresholds. These thresholds are derived by aggregating different metric distributions while preserving their statistical properties.
The second method enables the assignment of ratings to systems, for a given scale, using rating thresholds. These thresholds are calibrated such that it is possible to distinguish systems based on their metric distribution. For each rating, these thresholds set the maximum amount of code that is allowed in all risk categories.
Empirical and industrial studies provide evidence of the usefulness of the approach. The empirical study shows that ratings for a new test adequacy metric can be used to predict bug solving efficiency. The industrial case details the quality analysis and evaluation of two space-domain simulators.<br>A adoção na indústria do uso de métricas de código fonte para a avaliação de qualidade tem sido dificultada por dois problemas: (i) pela dificuldade em interpretar métricas de forma qualitativa; e (ii) pela impossibilidade de agregar métricas num valor único que capture de forma fiel a qualidade do sistema como um todo.
Esta dissertação propõe uma solução para estes problemas utilizando dois métodos que usam valores-limite derivados de um benchmark industrial.
O primeiro método caracteriza medições em diferentes áreas de risco através de valores-limite de risco. Estes valores-limite são derivados através da agregação das distribuições de métricas preservando as suas propriedades estatísticas.
O segundo método, dada uma escala, permite atribuir uma classificação a sistemas de software, usando valores-limite de classificação. Estes valores-limite são calibrados para permitir diferenciar sistemas baseada na distribuição de métricas definindo, para cada classificação, a quantidade máxima de código permissível nas categorias de risco.
Dois estudos evidenciam os resultados desta abordagem. No estudo empírico mostra-se que as classificações atribuídas para uma nova métrica de teste podem ser usadas para prever a eficiência na resolução de erros. No estudo industrial detalha-se a avaliação e análise de qualidade de dois simuladores usados para missões no espaço.

Today when environmental consciousness resumes day by day, the countries all over the world have already begun to make the regulation that have wanted enterprises to face the issue. As if WEEE and RoHS have already become the focus that enterprises have paid attention to. So, enterprises must channel into the green concept in the products, it is since Plan, Design, Build, Manufacture, Sale and Distribution, Scrap and Recycle, consider the impact of the environment and norm of the regulation. Thus, the fund, equipment, manpower cost to input that the green products want of enterprises are an inevitable doing in the test amount focal point, it is really important which cost information is invested so how enterprises to know.
This research structures the enterprises’ value chain procedure and find out the important working project to the incurred cost information and structure the incurred cost model.
The value chain procedure includes the main activity and the supporting activity, the main activity contains every stage workflow of green product life cycle, and supporting activity contains the activity with added value.
In addition, in all green products value chain procedure, these important working projects will be incurred out than the information of the extra cost increased before not channelling of enterprises into the green products in the past, call green products incurred cost working projects.
According to these projects, them could be subdivided into incurred cost details and structured the incurred cost model. It is hope to offer the enterprises clear cost information and the cost is put into an important basis considered.

碩士<br>國立清華大學<br>工業工程與工程管理學系<br>98<br>Many countries have enforced environmental protection directives due to the recent awareness of environmental issues. They require the products imported have to comply with the directives by lifecycle assessment. This results in a huge impact on product development. Currently most products perform lifecycle assessment at the production/manufacturing stage. Any problems discovered so late can only be corrected through engineering changes, which involve high cost but low efficiency. The assessment needs to be conducted at early stages of a product lifecycle. However, previous studies failed to offer rigorous or quantitative methods on this matter. Thus, this research proposes a systematic method that reduces the environmental impact in the system design stage based on automatic variation of product structure. Product structure is optimized with the objective as minimization of CO2 emission of the entire product development process. CAD technologies are integrated for automatic product assembly and interference check of assembly process. Genetic Algorithms are applied to optimize selection of components while maintaining the product design functions. The assembly sequence is determined by Tabu search. Dynamic programming techniques are employed to choose suppliers. The results are combined to obtain optimal product structure design in consideration of CO2 emission during three major phases of a product life cycle: raw material production, assembly/manufacturing, and transportation. This work is the first study that utilizes domestic LCA data for quantitative analysis of the environmental impact during product development. It realizes the concept of sustainable design using actual data. The proposed method works as a decision-making tool in product design for reducing environmental impact.

Understanding how consumers evaluate products is of great interest to market researchers. Different approaches focus on how consumers compare, combine or process attributes (Bettman, Luce and Payne 1998, 2008; Chen and Chaiken 1999; Cohen, Fishbein and Ahtola 1972). While attribute evaluation is clearly central to these approaches, what makes particular product attributes influential to consumers’ overall evaluation of the product is not entirely clear. One of the central goals of the current work is to examine why certain product attributes are appealing or unappealing, and to explore the implications of this for product evaluation research, including work on choice and persuasion, and more focused investigations on the role of trivial attributes.
I structure this framework around two broad issues: First, I suggest that product evaluation is based on an attribute’s ability to fulfill a particular goal. Furthermore, I examine the specific processes by which activated goals influence the role of product features on the evaluation of the product itself. Specifically, I suggest that goals are more likely to influence the impact of product attributes on product evaluation when goals are activated and perceived to fit with the product.
Second, I focus on three product related features within the consumption environment that are likely to activate certain goals, especially extra-consumption goals (i.e. goals that are not directly relevant to the function of the product, but that may nevertheless exert an important influence on product evaluation). Those aspects include the context in which the product is evaluated (e.g. choosing between multiple products versus evaluating an individual product), product category associations (e.g. fair trade and coffee), and even specific features of the product being evaluated (e.g. shampoo with “eco-friendly” ingredients). These aspects can activate goals that influence the role of the product’s specific features on overall evaluation.<br>Thesis (Ph.D, Management) -- Queen's University, 2010-11-29 16:55:13.751

Full textAbstract:
碩士<br>國立中山大學<br>資訊管理學系研究所<br>98<br>Before making a purchase, more and more consumers in recent years are consulting other consumers’ product reviews online, to assist them in making a purchasing decision. However, due to the massive amount of online reviews, consumers can hardly get useful information effectively. Hence, information overload has become a problem. Query functions in search engines like Yahoo and Google can help users find some of the reviews that they need for specific information. Nevertheless, the returned pages from these search engines are still beyond the visual capacity of humans.
Therefore, this study aims to develop a new concept of personalized recommendation based on consumer product reviews to solve the afore-mentioned problem. A series of laboratory experiment examines the effectiveness of the proposed approach and compares this approach with other traditional approaches on precision of recommendation. Meanwhile, the meaning of the recommendation behind each approach is explained. Lastly, the prototype of recommendation system based on the proposed approach is illustrated. Our system can display the trend of the gathered consumer reviews in a graphical way, such as a product satisfaction run chart. The development of recommendation systems is not only beneficial to consumers, but also advantageous to sellers.

碩士<br>國立交通大學<br>資訊管理研究所<br>101<br>With its flourishing development of Web 2.0, people not only passively receive the information, but actively share the information with others by web 2.0 technology. Yet, for people, there is the information overload problem to filter the explosive information and find what people want hard. To solve the problem, the recommendation systems such as based on users’ preferences or the contents of items are the widely utilized solution. However, the interest influence, follow influence and personalized weights of influences may be the important factor for recommendation. Besides, the related researches do not consider the review influence and the time factor in recommendation.
In our work, we proposed the novel recommendation method base on two types of influences including the interest influence and follow influence, and personalized weights for each influence for recommending products in cosmetic-sharing website, Urcosme. The experimental results show our proposed methods improve the performance of recommendation.

This paper presents the release of clustering process (Release Grouping Procedure, RGP) method Connector distinction, trying to simplify the complexity of the product disassembly planning. On the other hand can be to assess the value of dismantling Connector , there will be no dismantling value Connector choose not to disassemble, reduce unnecessary dismantling costs in order to improve the overall product recovery efficiency.This study was to verify the feasibility of disassembling Connector based planning, so will do total disassembly and selective disassembly planning.First, do total disassembly planning to build the release diagram and breadth-first search and then use the Forward phase heuristic to seek out the best solution, after cost estimates for the Connector, and then the non-economic Connector for design improvements to improve product recovery efficiency. After the completion of the total disassembly planning, then selective disassembly planning established demolition selected release diagram, do the same with total disassembly planning process step, the final selection results selective disassembly planning will choose not to have economic Connector , the product can be reduced unnecessary waste disassembly process, helps to improve product recovery efficiency.
