Abstract:

Nowadays, industries face very strong challenges because of the high competitiveness between them. In fact, they are required to offer products with high quality and minimum cost in the minimum time. Since most of the characteristics and costs of the product and its manufacturing process are fixed in the design phase, this paper is focused on this strategic phase. Indeed, a new integrated product design approach is presented. It considers at the same time design requirements, materials characteristics, manufacturing parameters and the assembly process specifications. The developed approach is quantitative. Actually, the decision making is based on all its steps on objective and subjective indicators. To validate the integrated approach, a case study on the Schrader Robot is developed. This application allows to choose the most appropriate materials, manufacturing processes and assembly solution of its different components.

Abstract:

For problems, such as evaluation model selection is not appropriate and accuracy of the assessed value is low, exist in the reliability assessment of mechanical and electrical product, we propose a comprehensive reliability assessment process for mechanical and electrical products. In this paper, we discuss methods of reliability data collection and collation first. Then, criteria of preliminary screening for failure data are established. Furthermore, considering that life cycle of product is characterized by varied environment and varied population, it gives the method and steps for reliability assessment of produces. In addition, the process is used in the reliability assessment of products, and the calculation result illustrates that the process can be successfully applied to engineering practice. The process proposed in this paper provides a technical means for model selection in reliability assessment of mechanical and electrical product, and serves as the theoretical guidance for reliability validation and reliability design of product.

Abstract:

Product alternatives, which emerges from large number of websites during searching, accounts for some hesitation experienced by customers in selecting satisfying product. As a result, making useful decision with many trade-off considerations becomes a major cause of such problem. Several approaches have been employed for product selection such as, fuzzy logic, Neuro-fuzzy, and weighted least square. However, these could not solve the problem of inconsistency and irrelevant judgement that occur in decision making. In this study, Ontology-based Analytic Hierarchy Process (AHP) was used for enhancing selection of product preferences. The model involved three fundamental components: product gathering, selection and decision making. Ontology Web Language (OWL) was utilized to define ontology in expressing product information gathering in a standard and structured manner for the purpose of interoperability while AHP was employed in making optimal choices. The procedure accepts customers’ perspectives as inputs which are classified into criteria and sub-criteria. Owl was created to foster customers’ interaction and priority estimation tool for AHP in order to generate the consistency ratio of individual judgements. The model was benchmarked with Geometric Mean (GM), Eigenvector (EV), Normalized Column Sum (NCS) Weighted Least Square (WLS) and Fuzzy Preference Programming (FPP). First and second order total deviations and violation rate were the performance parameters evaluation with AHP. The results showed that the minimum and maximum units of products are 2,452and 3,574, respectively. These implied that the proposed model was consistent, relevant and reflected a non-violation of judgment in selection of product preferences.

Abstract:

The development of additive manufacturing allows the transformation of technological processes and the redesign of products. Among the most used methods to support additive manufacturing, the design can be optimised through the integration of topology optimisation techniques, allowing for creating complex shapes. However, there are critical issues (i.e., definition of product and process parameters, selection of redesign variants, optimised designs interpretation, file exchange and data management, etc.) in identifying the most appropriate process and set-ups, as well as in selecting the best variant on a functional and morphological level. Therefore, to fully exploit the technological potentials and overcome the drawbacks, this paper proposes a systematic redesign approach based on additive manufacturing technologies that integrate topology optimisation and a tool for selecting design variants based on the optimisation of both product and process features. The method leads to the objective selection of the best redesigned configuration in accordance with the key performance indicators (KPIs) (i.e., functional and production requirements). As a case study, the redesign of a medical assistive device is proposed, previously developed in fused filament fabrication and now optimised for being 3D printed with selective laser melting.

Abstract:

The thesis presents research carried out in the field of design for microassembly (DFµA), a field that has hereto been characterised by the absence of well defined methodologies intended to facilitate transfer of prototypes from the research lab to production on industrial scale. A DFμA methodology has been developed, serving the purpose of integrating product and micro assembly process development. It aims in particular at increasing the efficiency of the microproduct development process, decreasing the development time and the product and process cost, and enhancing the product quality. Chapter 1 presents the motivations, objectives, and structure of the thesis. The work carried out is inspired by the need to overcome barriers currently existing between the making of single research products and production on an industrial level. The main objective is to contribute to the creating of a novel DFμA that supports product design and process selection, thereby facilitating the efficient assembly of complex three-dimensional miniaturised devices. This is complemented by a range of secondary targets that deal with the development and verification of supporting methods and models related to DFμA. The summary of a comprehensive literature review is given in chapter 2. The survey provides results of studies closely related to the work reported in this thesis and relates that work to a larger ongoing dialogue about the topic of assembly and design in the microworld. Chapter 3 outlines the research approach adopted here for the developing of a DFμA methodology. It carefully analyses the way in which the knowledge gaps identified can be addressed and how the stated objectives can best be achieved. The key contributions made to the developing of a DFμA methodology are presented in chapters 4,5, and 6. The micro assembly process capability model is described first, in Chapter 4. It constitutes the first attempt made at introducing a general framework for capturing of microassembly characteristics. The model developed enables selection and characterisation of microassembly processes. A framework to characterise the model's application to microjoining, -feeding, and -handling is as well suggested. Chapter 5 concerns the actual DFμA methodology. The methodology's layout and structure are introduced in detail. Moreover, the main functions and key phases of the methodology are explained. Special attention is paid to the integration of the microassembly process capability model and to the development of further elements used within the methodology, such as support in product design. Provided in Chapter 6 is a comprehensive analysis of conventional DFA guidelines, intended to explain how the microspecific guidelines have been formulated. The chapter also describes how these are implemented within the overall DFμA methodology. The procedure of validating and illustrating the methodology, which includes applying it to practical test cases, takes place in Chapter 7. The thesis is concluded in Chapter 8, wherein evidence of the originality of the knowledge contribution achieved through the work presented is highlighted.

Abstract:

In this thesis, a subset of materials and products have been considered - those of sports equipment. First the relevant information about each is explored and structured in a database. This information is presented in a standard profile - a description of the character of a material - or as a 'map' of the space of materials - a visualisation of material behaviour. Two-dimensional maps displaying pairs of technical properties of materials are well known. In multiple dimensions, a completely new technique is required, that of multi-dimensional scaling. This is a technique for revealing 'similarities' and relationships in complex data sets; the full attribute profile of a material is precisely such a set. Both two-dimensional and multi-dimensional maps are explored as tools for product design. For visualising similarities between lightweight structural products a second technique is required, that of mapping material properties (like elastic modulus and yield strength) with specific geometries (like second moment of area and section modulus). Here, these maps are used to compare similar functional elements in specific products and their relationship to material possibilities. The intention of this thesis is to develop an understanding of the interaction of materials and design (MAD). These interactions require new methods of selection which are then demonstrated in a set of design tools: one for material selection and a second for structured inspiration. For each, a database of materials is linked to one of products. With this process, two methods of material selection, based on the visualisation techniques described earlier, are integrated with those of analysis - selection by similarity and selection by synthesis. In selection by similarity, the set of possible material solutions is expanded by comparing materials based on technical or aesthetic attributes. In selection by synthesis, innovative material solutions are created by assembling elements from those that are found in existing products. The same database is manipulated by a digital viewer for structured inspiration - for this, a series of images of materials are presented to the designer in random order. The viewer provides a visual stimulus for material selection and the designer is immediately linked to the appropriate information if requested - selection by inspiration. The MAD process of material selection requires the creative combination of each of these methods.

Abstract:

Product improvement is a serious issue facing industry today. And while response surface methods have been developed which address the process mean involved in improving the product there has been little research done on the process variability. Lack of quality in a product can be attributed to its inconsistency in performance thereby highlighting the need for a methodology which addresses process variability. The key to working with the process variability comes in the handling of the two types of factors which make up the product design: control and noise factors. Control factors can be fixed in both the lab setting and the real application. However, while the noise factors can be fixed in the lab setting, they are assumed to be random in the real application. A response-model can be created which models the response as a function of both the control and noise factors. This work introduces criteria for selecting an appropriate response-model which can be used to create accurate models for both the process mean and process variability. These two models can then be used to identify settings of the control factors which minimize process variability while maintaining an acceptable process mean. If the response-model is known, or at least well estimated, response surface methods can be extended to building various confidence regions related to the process variance. Among these are a confidence region on the location of minimum process variance and a confidence region on the ratio of the process variance to the error variance. It is easy to see the importance for research on the process variability and this work offers practical methods for improving the design of a product.

Abstract:

The following report consists of a master thesis (30 credits) within product development. The thesis is written by Philip Ragnartz and Axel Staffanson, both studying mechanical engineering at Mälardalens University. Developing new components for a production line is costly and time consuming as they must be made from manual measurements and must go through all the conventional manufacturing (CM) steps. Eventual design mistakes will be discovered after the component have been manufactured and tested. To fix the design a completely new component must be designed and therefore double the overall lead time. The purpose of this thesis is to establish how additive manufacturing (AM) can best be used to minimize the cost and lead time in the development of new components. The study was performed by looking at the current product development process in the automotive industry at a large company, here by referred to as company A. 56 components already manufactured at company A´s own tools department was examined and compared to different AM methods. The aim of this was to get a larger pool of data to get an average on production time and cost and see how this differ to the different AM methods. Additionally, two work holders were more closely examined in a case study. Work holder one is a component in the production line that occasionally must be remanufactured. It was examined if this problem could be solved with a desktop plastic printer to hold up for a production batch. Work holder two was the development of a new component, this was to examine the use of printing the component in an early stage impact the development process. The findings from this study is that AM can today not be used in a cost efficient way in manufacturing or development of simple components. This is due to the cost of a metal 3D-printer is still very high, and the building material even higher. This results in components that gets very expensive to make compared to producing them with CM. For design evaluation to be cost efficient there will have to be a design fault in over 12 % of the newly design components for it to be cost effective to print the design for validation before sending it to be manufactured. There are however a lot bigger potential savings in the lead time. Producing the end product with a metal 3D-printer can cut down the lead time up to 85 %. This is thanks to the fact that the printer will produce the component all in one step and therefore not get stuck in between different manufacturing processes. The same goes for design evaluation with printing the component in plastic to confirm the design and not risk having to wait for the component to be manufactured twice. Despite the facts that it is not cost efficient to use AM there are other factors that play an important role. To know that the designed components will work will create a certainty and allow the development process to continue. In some cases it will also allow the designer to improve the design to function better even if the first design would have worked. As AM is expanding machines and build materials will become cheaper. Eventually it will become cheaper to 3D-print even simple components compared to CM. When this occurs, a company cannot simply buy a 3D-printer and make it profitable. There is a learning curve with AM that will take time for the designers to adapt to. Therefore, it is good to start implementing it as soon as possible as it allows for more intricate designs and require experience to do so.

Abstract:

Context: At the core of choosing what features and level of quality to realize, and thus offer a market or customer, rests on the ability to take decisions. Decision-making is complicated by the diverse understanding of issues such as priority, consequence of realization, and interpretations of strategy as pertaining to the short-term and long-term development of software intensive products. The complexity is further compounded by the amount of decision support material that has to be taken into account, and the sheer volume of possible alternatives that have to be triaged and prioritized; thousands or even tens of thousands of requirements can be the reality facing a company. There is a need to develop the functionality that is strategically most significant, while satisfying customers and being competitive, time efficient, cost effective, and risk minimizing. In order to achieve a balance between these factors, all the stakeholders, within an organization, need to agree on the strategic aspects and value considerations to be considered, and their corresponding relative importance. Objective: The objective of this thesis is to provide enhanced decision support for product managers faced with decision-making challenges. This involves, but is not limited to, enhancing the alignment between the product and portfolio management with respect to product strategies, and enabling the use of value as a basis for product management and development related decisions. Method: A number of empirical studies, set in industry, have been performed. The research methods used span from systematic mapping, and systematic reviews to case studies, all aligned to identify possibilities for improvement, devise solutions, and incrementally evaluate said solutions. Close collaboration with industry partners was at the core of the research presented in this thesis. Result: The MASS method presented in this thesis can be used to evaluate strategic alignment and identify possible root causes for misalignment. To strengthen strategic alignment, the Software Value Map and corresponding decision support material, proposed in the thesis, can be used by product managers for making effective and efficient strategic decisions in relation to portfolios, products and process improvement, following a systematic and aligned process. Conclusions: The area of software product management, in the context of market-driven software intensive product development, is a field with unique challenges. The specifics of the solutions are based on industry case studies performed to gauge state-of-the-art, as well as identify the main challenges. The decision support developed takes the form of maps and frameworks that support software product management on product and portfolio level decisions, strategic alignment, value-based requirements selection, and value-based process improvement.

Abstract:

To optimize biodiesel manufacturing, many reported studies have built simulation models to quantify the relationship between operating conditions and process performance. For mass and energy balance simulations, it is essential to know the four fundamental thermophysical properties of the feed oil: liquid density (Ï L), vapor pressure (Pvap), liquid heat capacity (CpL), and heat of vaporization (Î Hvap). Additionally, to characterize the fuel qualities, it is critical to develop quantitative correlations to predict three biodiesel properties, namely, viscosity, cetane number, and flash point. Also, to ensure the operability of biodiesel in cold weather, one needs to quantitatively predict three low-temperature flow properties: cloud point (CP), pour point (PP), and cold filter plugging point (CFPP). This article presents the results from a comprehensive evaluation of the methods for predicting these four essential feed oil properties and six key biodiesel fuel properties. We compare the predictions to reported experimental data and recommend the appropriate prediction methods for each property based on accuracy, consistency, and generality. Of particular significance are (1) our presentation of simple and accurate methods for predicting the six key fuel properties based on the number of carbon atoms and the number of double bonds or the composition of total unsaturated fatty acid methyl esters (FAMEs) and (2) our posting of the Excel spreadsheets for implementing all of the evaluated accurate prediction methods on our group website (www.design.che.vt.edu) for the reader to download without charge.

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR
A quantidade de websites de comércio eletrônico vem aumentando rapidamente, no entanto, questões envolvendo a usabilidade muitas vezes são esquecidas. Esta pesquisa partiu do pressuposto de que a ineficiência da apresentação de produtos em websites de comércio eletrônico no momento de compra prejudica a realização da tarefa pelo usuário, resultando em frustrações e perdas econômicas. Objetiva-se com esta dissertação melhorar a usabilidade de websites de comércio eletrônico, através da identificação de fatores que facilitem o processo de seleção de um produto pelo usuário no momento da compra; contribuir para o aprofundamento de questões de usabilidade; além de colaborar para o fortalecimento dos estudos de IHC (Interação Humano- Computador) no país. Alguns métodos e técnicas foram usados, em quatro etapas: Primeiramente, através da Análise da Tarefa observaram-se as ações de clientes no momento da seleção de 2 produtos no ambiente real. Posteriormente, através da Avaliação Heurística buscou-se avaliar a interface dos websites de eletrodomésticos selecionados para a pesquisa com base na lista de heurísticas vindas da Análise da Tarefa. Em um terceiro momento, através da técnica Avaliação Cooperativa analisou-se o processo de seleção dos mesmos produtos pelo cliente em websites de comércio eletrônico (ambiente virtual). Por fim, foram analisadas e comparadas as ações dos usuários nos dois ambientes (loja física e virtual) a fim de avaliar as diferenças existentes entre estas no momento de seleção do produto. Através deste trabalho, a hipótese pôde ser confirmada e evidenciou-se que as páginas de apresentação do produto em websites de comércio eletrônico possuem níveis baixos de usabilidade, prejudicando a realização da tarefa pelo usuário, resultando em frustrações e na maioria das vezes a não efetivação da compra.
The amount of e-commerce websites has increased rapidly. However, issues involving their usability many tomes have been overlooked. This research is concerned about the inefficiency of the presentation of products in general, in ecommerce websites at the moment of purchase. This incompetence jeopardizes the accomplishment of the task by the user, who will become frustrated and unsatisfied not to mention the economic losses. It is intended, with the research, to improve the usability of the e-commerce websites through the identification of factors that will enable the user to select better his products at the moment of purchase. Moreover, it is intended to contribute to the development of solutions of usability issues and to improve the studies of IHC. Some methods and techniques were used, in four stages: First of all, through the Task Analysis, we could observe the clients actions at the very moment of selection of two products from the real store; Secondly, through the Heuristic Evaluation, we tried to study the interface of the domestic appliance websites selected for a survey from the Task Analysis; On a third stage, through the Cooperative Evaluation, we analyzed the process of selection of the same products mentioned above by the clients on virtual store; At last, the actions of the users were both analyzed and compared in the virtual store and the real store, in order to verify the differences between them at the moment of the products selection. By means of this work, the hypothesis could be confirmed and became evident that the interfaces of the e-commerce websites showed low levels of usability, risking the performance of task by the users besides leading the user to frustration and most of the time making him give up the purchase.

Abstract:

Cette recherche vise à proposer une approche intégrée permettant la prise en compte simultanée des paramètres Produits / process dans le cadre d’une fabrication par ajout de matière. Le développement produit est en profonde mutation, prenant en compte les contraintes de personnalisation, de temps de mise sur le marché de plus en plus court, la volonté d’une approche eco-responsable etc. Ce changement de paradigme conduit à s’intéresser au choix du couple matériau /process dès la phase de conception afin de prendre en compte les contraintes liées au procédé identifié. Cette approche multi critère s’intéresse à la fois au couple matériau procédé mais prend en compte les aspect fonctionnels de la pièce. Ainsi ce travail de thèse présente une méthodologie de décision générique, basée sur des outils de prise de décision multicritères, qui peut non seulement proposer une solution satisfaisant les contraintes liées aux matériaux, processus et processus par addition de matière, mais propose également de servir de guide aux concepteurs permettant un choix raisonné basé sur des combinaisons matériau-machine orientées conception et obtenu à partir d’une base de données de 38 fournisseurs internationaux de machine de fabrication par ajout de matière
The doctoral research focuses to build an integrated approach that can simultaneously handle the product and process parameters related to additive manufacturing (AM). Since, market dynamics of today are constantly evolving, drivers such as mass customization strategies, shorter product development cycles, a large pool of materials to choose from, abundant manufacturing processes, etc., have made it essential to choose the right compromise of materials, manufacturing processes and associated machines in early stages of design considering the Design for AM guidelines. As several criteria, material attributes and process functionality requirements are involved for decision making in the industries, the thesis introduces a generic decision methodology, based on multi-criteria decision-making tools, that can not only provide a set of compromised AM materials, processes and machines but will also act as a guideline for designers to achieve a strong foothold in the AM industry by providing practical solutions containing design oriented and feasible material-machine combinations from a database of 38 renowned AM vendors in the world today

Abstract:

The substantial demand of the customer for the conservation of natural resources and of the environment puts pressure on the automotive industry to reduce fuel consumption and emissions. One response to this challenge is to reduce car body weight. Hence car body development has shown an increase in the use of light weight materials that demand new production methods and joining technologies. Accordingly car body engineers have progressively less time to assess the manufacturing cost of an increasing number of new design concepts with new material and corresponding joining techniques. A review of the pertinent literature shows that there is no established methodology enabling automotive body engineers to make a rough manufacturing cost estimate of different new design concepts in the early phase of the Product Development Process. The aim of the present thesis is to provide car body engineers with a cost estimating methodology that makes it possible for them in the preliminary phase of the design process to estimate the manufacturing cost of new design concepts more systematically, hence more reliably, thus enhancing cost reduction. The methodology is based on the notion of Standardised Working Contents, which, as fundamental units of work, enable designers to compare the financial requirements of various new design options with greater facility and greater accuracy. Furthermore the methodology identifies the most cost efficient Joining Technique combination with a high degree of reliability. Economical and technical data required for the methodology are gathered from an industrial survey in collaboration with the design, planning, finance and manufacturing departments of a leading automotive company. Dynamic Programming taken from the area of Operations Research is employed to provide the optimal Joining Technique combination in terms of manufacturing cost of the car body design concept under scrutiny. Results obtained from an automotive industrial case study confirm the effectiveness of the methodology while pointing out its limitations and possibilities.

Abstract:

The stainless steel industry is an industry which manufactures one of the most used ma-terials in the world. Even though the vast size of the industry many might not reflect werethe steel comes from when buying their IKEAcutlery etc. But in fact this industry is moreintricate and complex than one might think.During the manufacturing process, the steelgoes through several processes. One of thoseprocesses is done by treating the steel withstrong acid. This chemical process is calledpickling. The pickling process is what createsthe characteristic smooth and shiny surface ofa product made in stainless steel.This thesis is about the development of a testunit that is able to effectively test the ASRA(Acid Sludge Removal Apparatus) filter cloths.The ASRA is a filtration system developed by Scanacon in Stockholm that filtrates and puri-fies acid that is used during the pickling pro-cess of a steel manufacture process. Today, it is complicated, time consuming and dangerous totest and evaluate different filter cloths in orderto find the cloth that provides the best result,since the tests has to be conducted on the realsystems. The aim of this thesis was therefore tosolve these problems. Scanacon wanted to findan alternative solution, that would not includeinteraction with the real filtration system. Theyalso wanted a portable and safe solution. To solve the problem a iterative design pro-cess called RDCD which stands for research, design, create & delivery was developed. Theprocesses was heavily influenced by the CDIO process (Conceive, Design, Implement & Ope-rate). After the research phase was conducted it was decided that a small filter analysis productwould be the best way to solve the problem. The product was then developed one com-ponent at a time. During the project several prototypes and test was created and conductedin order to validate the design.The result is a small filtration unit speciallydesigned to simulate the ASRA system. Theproduct is able to rapidly test various filtercloths in an easy way, without putting the user in harm’s way. After the tests has been perfor-med can the user can identify which cloth that worked the best. The product is small enoughto be possible to be carried in a hard case bag,which in turn affords portability.
Stålindustrin är en industri som tillverkar ettav de mest använda materialen i världen. Trotsindustrins enorma storlek är det kanske intemånga som reflekterar varifrån stålet kommerifrån när man köper exempelvis IKEA bestick.Men faktum är att den här industrin är mycketmer invecklad och komplex än vad man kan tro. Under tillverkningsprocessen går stålet ige-nom flera processer. En av de här processerna genomförs genom att behandla stålet med starksyra. Den kemiska processen kallas för betningoch är det som ger en produkt tillverkad i stålden karaktäristiska lena och glänsande ytan. Den här examensrapporten handlar om ut-vecklandet av en test enhet som effektivt kan testa filter dukarna till ASRA (Acid SludgeRemoval Apparatus) systemet. ASRA systemetär ett filtreringssystem utvecklat av Scanaconi Stockholm som filtrerar och renar syran som används under betningsprocessen vid stål-tillverkning. Idag är det komplicerat, tidskrä-vande och farligt att testa och utvärdera olika filterdukar för att ta reda på vilken duk somger bäst resultat, eftersom att testerna måstegenomföras på de riktiga systemen. Målet fördet här examensarbetet var därför att lösa dehär problemen. Scanacon ville ha en alternativlösning som inte kräver interaktion med deriktiga systemen. De ville också ha en portabeloch säker lösning. För att lösa problemet utvecklades en itera-tiv designprocess kallad RDCD som står för research, design, create & delivery. Processen var tungt influerat av CDIO (Conceive, De-sign, Implement & Operate) processen. Efter att researchfasen var genomförd bestämdesdet att en liten filteranalysatorprodukt var detbästa sättet att lösa problemet på. Produktenutvecklades sedan en komponent i taget. Underprojektets gång har flera prototyper byggts och flera tester genomförts för att validera designen. Resultatet är en liten filtreringsenhet som är specialdesignad för att simulera ASRA syste-met. Produkten kan snabbt testa oliak filterdu-kar på ett enkelt sätt, utan utsätta användaren för fara. Efter att testerna genomförts kananvändaren identifiera vilken duk som funkatbäst. Produkten är tillräckligt liten för att fåplats i en hårdplast väska, vilket ger produktenden efterfrågade portabiliteten.

Abstract:

In the modern competitive environment, firms have to offer a variety of products to their customers in a cost effective manner. One way of achieving this goal is through the use of product platforms and product families. The choice of product materials and manufacturing processes has a significant effect on the ability to derive variants from these product platforms and families. Unfortunately, most economic analyses of materials selection rarely include the effect on the product family, and if they do they are viewed as static and passive investments. In reality, the decision to produce an additional variant is a “right, but not an obligation” — it can be viewed as a real option. A methodology to value the option of producing a follow-on variant product for an a posteriori (or bottom up) product family is proposed. This method uses inputs that are readily available for most product development teams. An automotive instrument panel beam case study is used to illustrate the method. Results from the case study show that while the follow-on variant option did not affect the relative economic preference of the materials, the value of the options associated follow-on variants accounted for a significant portion of total development project value. Valuations performed using both the binomial and Black-Scholes methods did not show significant differences between the methods. Material and manufacturing process characteristics are shown to have an effect on follow-on variant option value. The product lifetime and annual production volume of the follow-on variant are shown to have significant effects on option value. Initial variant product lifetime and underlying asset risk are shown to have less of an effect on option value.

Abstract:

Although a similarity between software and product development processes exists, concept selection is not treated as a core stage in software development whereas it is an important stage in product development. In this paper, we propose to apply concept selection methodologies in design engineering (modularized Quality Function Deployment (QFD) and perceptual concept evaluation methodologies) to software development. In particular, we demonstrate how these methods may be used for software architecture and software module concept selections. Modularized QFD matrices help software developers relate customer requirements to software requirements, and then to software module requirements. At the same time, importance of customer requirements is allocated to software requirements and then to software module requirements. These requirements and normalized worth serve as concept evaluation criteria and their weights. The proposed approach is illustrated using image search software as an example.

Abstract:

Abstract This paper describes our proposed methodology for process selection that applies to the early stages of product design. We focus on net-shape manufacturing processes and identify the major factors that affect the selection of an appropriate process. The sequence at which designers typically make decisions depends largely on the nature of the product and the development environment. Thus, a versatile methodology should consider all the factors simultaneously in assessing the suitability of the candidate processes. The paper describes three types of knowledge that represent the compatibility of various processes to a given set of specifications: a) Case-based knowledge, i.e., templates of good, bad, and poor combination of decisions, b) Ordinal relationships among candidate processes based on interval analysis of cost, and c) Life-cycle cost estimate. Each type of knowledge gives an evaluation of suitability (compatibility) of candidate processes. Our future challenge lies in combining these measures at various stages of product development. Our initial studies on relationships between process selection and influencing factors lead to a HyperCard stack which stores information in an object-oriented fashion. This stack contains information which is the basis for our future computer-aid for process selection.

Abstract:

There is a dire need for the development of an integrated information model for organizing and managing material and manufacturing related information, required for any product realization. In this paper, such an information framework for product, process and material modeling has been proposed to support the product’s form, function and behavior, its physical and functional decompositions, its design requirements and design rationale, and its material and process needs. A detailed, real-life case study of the water jet intensifier design system has been presented to show how this proposed framework could support, capture and utilize all necessary information required for the selection of the intensifier’s high-pressure cylinder material. The framework will also be able to provide sufficient information to quantify the eco-compatibility of products.

Abstract:

Abstract The design of modular products, or modular-product design, is a powerful design strategy that can boost the competitive edge of a company that employs its benefits. We introduce in this paper an approach for managing the influence of product modularity during concept selection of consumer products. We propose a process that consists of four steps. The first step is to define the business strategy and associated objectives for the product, based on an expanded definition of modularity. The second step is to prioritize the objectives using an objective tree. The third step is to establish design metrics and the final step is to weigh each metric by the design objectives. The outcome of the process is an overall objective metric (composite score) that is used for concept selection and is a measure of the balance of design objectives affected by modularity. Finally, three product concepts of varying modularity are analyzed using various design objectives to show that the selection of the best (most suitable) concepts depend fully on the design objectives and that the most modular designs are not necessarily the best.

Abstract:

This document is part of a series of technical notes describing the compilation of a new companion database that complements the UNU-WIDER World Income Inequality Database. It aims at facilitating the analysis of inequality as well as progress in achieving the global goal of reducing inequality within and across countries. This new dataset includes an annual series reporting the income distribution at the percentile level for all citizens in the world, regardless of where they live, from 1950 to the present. The global distribution is displayed along with the country-level information used to produce it. The dataset also includes estimates of various global absolute and relative inequality measures, and the income share of key population groups. All estimates are further disaggregated by the contribution of inequalities within and between countries, as well as by each country’s geographical region and income group. While previous technical notes described the selection of country income distribution series and the integration and standardization process to overcome the heterogeneity in original welfare concepts and other methods, I here describe all the necessary additional steps and assumptions made to construct the new global dataset.

Full text

Abstract:

This manual presents best practices on project selection, mix design, and construction to ensure a superior product when constructing thin asphalt overlays. Experience shows these treatments provide excellent performance when placed on pavements in fair to good condition using proper construction techniques. Though sometime referred to by other names, thin asphalt overlays have been widely used for pavement preservation throughout the world for over 50 years. Limited infrastructure funding at the local, state, and federal levels has resulted in greater emphasis on the use of pavement preservation techniques to extend pavement life and reduce maintenance costs. Thin asphalt overlays are one of many preventative maintenance treatments. Thin asphalt overlays are placed directly on existing pavement and can range from 1/2 inch to 1 1/2 inches in thickness. Thin asphalt overlays have proven to be an economical means for maintaining and improving the functional condition of an existing pavement since the 1960s. Specifically, this manual provides guidance for engineers regarding where and when to use thin asphalt overlays including: (1) Types and variations of thin overlays; (2) Materials and the design process; (3) Construction; (4) Quality Assurance; and (5) Troubleshooting. This chapter by chapter guidance enables an Agency’s engineers to design and construct a successful thin asphalt overlay project to completion. This manual is one of four new manuals prepared by the California Pavement Preservation Center (CP2Center) using funding from California Senate Bill 1 (SB-1), passed in April 2017. The other three manuals provide detailed design and construction information for (1) chip seals, (2) slurry surfacing, and (3) Cape seals. The creation of these manuals was a task funded entirely from SB-1 monies for the purpose of disseminating training and technical information on highway pavement preservation to local agencies throughout California.

Full text

Abstract:

Heavy minerals (HMs) are minerals with a specific gravity greater than 2.9 g/cm3. They are commonly highly resistant to physical and chemical weathering, and therefore persist in sediments as lasting indicators of the (former) presence of the rocks they formed in. The presence/absence of certain HMs, their associations with other HMs, their concentration levels, and the geochemical patterns they form in maps or 3D models can be indicative of geological processes that contributed to their formation. Furthermore trace element and isotopic analyses of HMs have been used to vector to mineralisation or constrain timing of geological processes. The positive role of HMs in mineral exploration is well established in other countries, but comparatively little understood in Australia. Here we present the results of a pilot project that was designed to establish, test and assess a workflow to produce a HM map (or atlas of maps) and dataset for Australia. This would represent a critical step in the ability to detect anomalous HM patterns as it would establish the background HM characteristics (i.e., unrelated to mineralisation). Further the extremely rich dataset produced would be a valuable input into any future machine learning/big data-based prospectivity analysis. The pilot project consisted in selecting ten sites from the National Geochemical Survey of Australia (NGSA) and separating and analysing the HM contents from the 75-430 µm grain-size fraction of the top (0-10 cm depth) sediment samples. A workflow was established and tested based on the density separation of the HM-rich phase by combining a shake table and the use of dense liquids. The automated mineralogy quantification was performed on a TESCAN® Integrated Mineral Analyser (TIMA) that identified and mapped thousands of grains in a matter of minutes for each sample. The results indicated that: (1) the NGSA samples are appropriate for HM analysis; (2) over 40 HMs were effectively identified and quantified using TIMA automated quantitative mineralogy; (3) the resultant HMs’ mineralogy is consistent with the samples’ bulk geochemistry and regional geological setting; and (4) the HM makeup of the NGSA samples varied across the country, as shown by the mineral mounts and preliminary maps. Based on these observations, HM mapping of the continent using NGSA samples will likely result in coherent and interpretable geological patterns relating to bedrock lithology, metamorphic grade, degree of alteration and mineralisation. It could assist in geological investigations especially where outcrop is minimal, challenging to correctly attribute due to extensive weathering, or simply difficult to access. It is believed that a continental-scale HM atlas for Australia could assist in derisking mineral exploration and lead to investment, e.g., via tenement uptake, exploration, discovery and ultimately exploitation. As some HMs are hosts for technology critical elements such as rare earth elements, their systematic and internally consistent quantification and mapping could lead to resource discovery essential for a more sustainable, lower-carbon economy.

Gender mainstreaming in local potato seed system in Georgia. International Potato Center, 2020. http://dx.doi.org/10.4160/9789290605645.

Full text

Abstract:

This report presents the study findings associated with the project “Enhancing Rural Livelihoods in Georgia: Introducing Integrated Seed Health Approaches to Local Potato Seed Systems” in Georgia. It also incorporates information from the results of gender training conducted within the framework of the USAID Potato Program in Georgia. The study had three major aims: 1) to understand the gender-related opportunities and constraints impacting the participation of men and women in potato seed systems in Georgia; 2) to test the multistakeholder framework for intervening in root, tuber, and banana (RTB) seed systems as a means to understand the systems themselves and the possibilities of improving gender-related interventions in the potato seed system; and 3) to develop farmers’ leadership skills to facilitate women’s active involvement in project activities. Results of the project assessment identified certain constraints on gender mainstreaming in the potato seed system: a low level of female participation in decision-making processes, women’s limited access to finances that would enable their greater involvement in larger scale potato farming, and a low awareness of potato seed systems and of possible female involvement in associated activities. Significantly, the perception of gender roles and stereotypes differs from region to region in Georgia; this difference is quite pronounced in the target municipalities of Kazbegi, Marneuli, and Akhalkalaki, with the last two having populations of ethnic minorities (Azeri and Armenian, respectively). For example, in Marneuli, although women are actively involved in potato production, they are not considered farmers but mainly as assistants to farmers, who are men. This type of diversity (or lack thereof) results in a different understanding of gender mainstreaming in the potato seed system as well. Based on the training results obtained in three target regions—Akhalkalaki, Akhaltsikhe, and Marneuli—it is evident that women are keen on learning new technologies and on acquiring updated agricultural information, including on potato production. It is also clear that women spend as much time as men do on farming activities such as potato production, particularly in weeding and harvesting. However, women are heavily burdened with domestic work, and they are not major decision-makers with regard to potato variety selection, agricultural investments, and product sales, nor with the inclusion of participants in any training provided. Involving women in project activities will lead to greater efficiency in the potato production environment, as women’s increased knowledge will certainly contribute to an improved production process, and their new ideas will help to improve existing production systems, through which women could also gain confidence and power. As a general recommendation, it is extremely important to develop equitable seed systems that take into consideration, among other factors, social context and the cultural aspects of local communities. Thus, understanding male and female farmers’ knowledge may promote the development of seed systems that are sustainable and responsive to farmers’ needs and capacities.
