Texto completoResumen
To study engineering can be difficult, especially transforming theoretical knowledge into practice. To address this issue, Otto and Wood have developed a reverse engineering and redesign methodology, suggesting that it can be used as a tool in the process of learning mechanical engineering and design. The aim with this report is to
evaluate this statement, emphasizing on the reverse engineering process and evaluating its usefulness as an educational tool. In order to fully understand the process, two cordless screwdrivers will be reverse engineered, functioning as an example throughout the report. A theoretical background of the process will be
introduced, including descriptions concerning the different steps and their encompassed tools, tests and methods. Trough the implementation, the screwdrivers are disassembled, analysed and experienced, resulting in a clear product specification
with information of components and product functions. One example is the assembly plan, were the product structure is presented as two subassemblies with “layer on layer” assembly. Another result of the implementation is that the reverse engineering
process was experienced in reality, exposing the required modifications necessary in order to function as an educational tool. The main issue for the process is its focus on customer needs instead of product focus. Therefore, it is suggested that a new reverse
engineering process based on the existing one should be developed, focusing more on the product and less on the customer to better suit an educational purpose.

Texto completoResumen
This thesis presents a software engineering process improvement study. The literature on software process improvement is reviewed. Then the current design verification process at one of the Software Engineering Departments of
the X Company, Ankara, Türkiye (SED) is analyzed. Static software development process metrics have been calculated for the SED based on a recently proposed approach. Some improvement suggestions have been made based on the metric values calculated according to the proposals of that study. Besides, the author'
s improvement suggestions have been discussed with the senior staff at the department and then final version of the improvements has been gathered. Then, a discussion has been made comparing these two approaches. Finally, a new software design verification process model has been proposed. Some of the suggestions have already been applied and preliminary results have been obtained.

The way engineers and engineering companies do their work has significantly changed over the past twenty years. This is mainly due to the simultaneous development of computers (particularly personal computers) and software. Most engineers are likely to use several engineering application programs and mainstream software packages. Hence, information from one application must be capable of being transferred into other packages for further processing or analysing and reporting or documentation purposes. This thesis aims to investigate aspects of data management and applications integration in process engineering design. It proposes a new method and model for data storage, manipulation and representation, on which new process design environments may be based. Several aspects of integrated process design database systems are examined, including data models, data handling, program control and integration. A system called PREMIS has been developed which uses an object-oriented approach to data management. It utilises templates which mimic specification sheets used in process industry for defining objects in a design environment. The use of methods promotes a consistent look and feel to the tools in the environment. The application of PREMIS to a real process engineering design example illustrates the benefits of object-oriented techniques to the process systems and design community. Templates can be manipulated as entities. They are displayed on the screen where they serve as the data input device for design information. Data on the templates and stored in the database can be shared and accessed directly by design programs. The dynamic nature of the object definitions encourages experimentation with the new data types and methods. The system also aims to demonstrate the advantages of employing advanced integration features of the Microsoft Windows operating system.

Texto completoResumen
Studies of the software engineering process are a natural extension of scope from that of conventional software development methodologies meeting the requirement for engineering large-scale software development. A new approach for dealing with the difficulties of large-scale software development in software engineeering is to establish an appropriate software engineering process system. This work researches into software engineering process system modelling and analysis. The delivered aims of this thesis are to investigate empirical software engineering process research and practices to solve current problems identified in software engineering process system modelling, to integrate current process models into a well founded and unifying framework and to lay theoretical foundations for the software engineering process as a formalised discipline.

As the demand for high-performing complex systems has increased, the ability of engineers to meet that demand has not kept pace. The creators of the traditional system engineering processes did not anticipate modern complex systems, and the application of traditional processes to complex systems such as spacecraft has repeatedly led to disastrous results. Too often, system safety is considered late in the design process, after much of the design is set. This thesis presents an iterative safety-driven system engineering process to address this problem. The process integrates safety into the design process, ensuring that safety is designed into the system, rather than added on. The techniques used in this process are: I) Intent Specifications, a framework for organizing system development and operational information in a hierarchical structure; 2) the System-Theoretic Accident Modeling and Processes (STAMP) model of accident causation, a framework upon which to base powerful safety engineering techniques; 3) STAMP-based Hazard Analysis (STPA) a novel hazard analysis technique; and 4) SpecTRM-Requirements Language (SpecTRM-RL), a formal modeling language. Intent Specification is used to document the design with complete traceability from system goals, requirements, and constraints to the operational design and software code. The STAMP framework is used to apply concepts from control theory to system engineering. STPA is used to identify hazards and eliminate them or mitigate their effects to ensure a safe system design. Finally, SpecTRM-RL is used to create the blackbox behavior models. An example of this process applied to an outer moon exploration mission is presented (in the form of an intent specification) and discussed. The specification focuses on the design of the control system and functionality of the scientific instruments, while also including a high-level design of the entire spacecraft. The application of the process described in this thesis demonstrates that design decisions are safety-driven, and that the results of the hazard analysis are integrated into all aspects of the design.

Texto completoResumen
The construction industry in the United Kingdom is a multi-billion pound business that contributes, on average 10% of the UK Gross Domestic Product (GDP). However, it is seen by many to be underachieving in terms of service delivery and investment opportunities. Projects are frequently late and over budget much to the disappointment of those involved in the industry and especially clients. Many investigations have been commissioned and resulting reports have suggested improvements in the way the industry is organised. Procurement of construction projects in the main are undertaken using methods that support fragmentation and adversarial relationships. However, with the introduction of partnering and prime contracting some improvements have been made. Procurement of a construction project begins with the strategies developed during briefing and is only complete when the facility is handed over to the client, some contract strategies allow for the facility to be completed once it is in operation, has been maintained and eventually is demolished. Costings and programmes are then related to life-cycle issues and aspects such as maintenance have to be taken into account during the facility development stages. The adoption of Concurrent Engineering (CE) is seen to offer the construction industry a way forward. Having been adopted extensively by manufacturing in its product development stages a similar adoption by the construction industry would go some way to achieving the 30% improvement in real terms suggested by Latham [1994] and Egan [1998]. The research described in the thesis aims to develop a new procurement method for the delivery of construction projects. The approach adopted was to identify current methods of procurement and the problems associated with each method. Then using Concurrent Engineering as a basis, a new procurement model was developed that offered potential improvements in the construction process between the stages of Clients Briefing and Detailed Design. The resulting model was evaluated through the application of CE principles into the process and by the presentation and discussion of the method with a number of industry participants, followed by the completion and assessment of a questionnaire. The model was shown to fulfil the principles of CE and could be adopted into construction. It offers a new approach to procurement which in turn would save costs and time and potentially improve the quality of the final construction product.

Abstract
A fundamental problem in the software engineering community
is how to achieve a state of continuous improvement. Over the last
ten years a number of studies have been made concerning various
tools, methods and software process improvement project life-cycle models,
but the problem persists and in many cases the software process
improvement program dies off within a year.
This thesis takes the assumption that the answer cannot be
reduced to a single tool or method, as there are no silver bullets
to complex problems. Instead the entire Software Process Engineering
system should be studied to find out what elements are necessary
for sustaining improvement activity on a long-term basis. Through
understanding the fundamental elements of a Software Process Engineering
system, the organization can manage and improve the system, tune
it up to the environment and make it efficient and effective. When
the system is operational, the software process improvement program,
which is a part of the system, can be sustained.
This research studies a case in which the Software Process
Engineering system of a large, multi-site telecommunications company
was successfully revised to meet the increasing improvement challenges.
The revised system has proven to be capable of sustaining continuous
improvement and case is used here to derive architectural design
models of a Software Process Engineering system.
Two such models are established here. One is a system model
that is independent of implementation and identifies the main elements
of a Software Process Engineering system. With the help of this
model, those responsible for process improvement in their organizations
can design, evaluate, and revise complete Software Process Engineering
systems. The other model is a design of a multi-site Software Process
Engineering organization, and identifies not only the operative
part of the organization but also the key non-operative elements
that a Software Process Engineering system needs to work with. With the
help of this model a multi-site organization can set up the operative
Software Process Engineering organization and plan for strategies
for managing the cooperation with the interfacing entities up front,
rather than ending up managing such contacts on a reactive fashion.

Texto completoResumen
In this study, an approach is proposed to model and simulate the systems engineering process of design projects. One of the main aims is to model the systems engineering process, treating the process itself as a complex system. A conceptual model is developed as a result of a two-phase survey conducted with systems engineers. The conceptual model includes two levels of activity networks. Each first level systems engineering activity has its own network of second level activities. The model is then implemented in object oriented modeling language, namely SysML, using block definition diagrams and activity diagrams. Another aim is to generate a discrete event simulation model of the process for performance evaluation. For this purpose the SysML model is transformed to an Arena model using an Excel interface and VBA codes. Three deterministic and three stochastic cases are created to represent systems engineering process alternatives, which originate from the same conceptual model but possess different activity durations, resource availabilities and resource requirements. The scale of the project and the effect of uncertainty in activity durations are also considered. The proposed approach is applied to each of these six cases, developing the SysML models, transforming them to Arena models, and running the simulations. Project duration and resource utilization results are reported for these cases.

McDonald, Andrew Gregory. "The Agile Web Engineering (AWE) process". Thesis, University of Glasgow, 2004. http://theses.gla.ac.uk/4065/.
Texto completoResumen
During the late 1990s commerce and academia voiced major concerns about the problems with development processes for Web Engineering. These concerns primarily centred upon the perceived chaotic and 'ad-hoc' approach to developing Web-based applications in extremely short time-scales when compared to traditional software development. Based on personal experience, conducting a survey of current practice, and collecting supporting evidence from the literature, I proposed a set of seven criteria that need to be addressed by a successful Web engineering process: 1. Short development life-cycle times; 2. Delivery of bespoke solutions and different business models; 3. Multidisciplinary development teams; 4. Small development teams working in parallel on similar tasks; 5. Business analysis and evaluation with end-users; 6. Requirements capture and rigorous testing; 7. Maintenance (evolution) of Web-based applications. These seven criteria are discussed in detail and the relevance of each to Web engineering is justified. They are then used to provide a framework to assess the suitability of a representative sample of well-known software engineering processes for Web engineering. The software engineering processes assessed comprise: the Unified Software Development Process; Dynamic Systems Development Method; and eXtreme Programming. These seven criteria were also used to motivate the definition of the Agile Web Engineering (AWE) process. A WE is based on the principles given in the Agile Manifesto and is specifically designed to address the major issues in Web Engineering, listed above. A number of other processes for Web Engineering have been proposed and a sample of these is systematically compared against the criteria given above. The Web engineering processes assessed are: Collaborative Web Development; Crystal Orange Web; Extensions to the Rational Unified Process; and Web OPEN. In order to assess the practical application of A WE, two commercial pilot projects were carried out in a Fortune 500 financial service sector company. The first commercial pilot of A WE increased end-user task completion on a retail Internet banking application from 47% to 79%. The second commercial pilot of A WE used by an Intranet development team won the company's global technology prize for 'value add' for 2003. In order to assess the effect of AWE within the company three surveys were carried out: an initial survey to establish current development practice within the company and two further surveys, one after each of the pilot projects. Despite the success of both pilots, AWE was not officially adopted by the company for Webbased projects. My surveys showed that this was primarily because there are significant cultural hurdles and organisational inertia to adopting different process approaches for different types of software development activity within the company. If other large companies, similar to the one discussed in this dissertation, are to adopt AWE, or other processes specific to Web engineering, then many will have to change their corporate goal of a one size fits all process approach for all software technology projects.

This paper will provide guidelines for the application of the System Engineering Process to Test Set Development. It will examine how to ensure customer's needs are met and that potential problems are avoided.
Furthermore, this paper will do more than compare the SE process to the Test Set Development. The processes recommended in this paper will enhance the test set development to reduce cost and increase reliability, and the paper will show the pay off of applying sound SE concepts.
The target of this paper will be Test Set Development related to Unit-Under-Test (UUT) Development. The keys to successfully designing a test set that are hinged on the UUT design will also be identified.

Texto completoResumen
Requirements engineering (RE) tools are software tools which provide automated assistance during the RE process. However, the RE practice relies on office tools rather than RE-tools provided by various companies. Reasons for not using the RE-tools include financial causes. The part of the problem also lies in the difficulty to evaluate such tools before acquisition to support the RE process. Hence, to support the completeness and effectiveness of RE-tool evaluation, a sound framework providing methodological guidelines is needed.
This work proposes an RE-tool evaluation approach (R-TEA), which provides a systematic way of the RE-tool assessment using two evaluation frameworks. The framework for the functional RE-tool requirements consists of three dimensions: representation, agreement, and specification. The representation dimension deals with the degree of formality, where requirements are described using informal, semiformal and formal languages. The agreement dimension deals with the degree of agreement among project participants through communication means. The specification dimension deals with the degree of requirements understanding and completeness at a given time moment. The second framework categorises the non-functional RE-tool features to process, product, and external requirements. Process requirements characterise constraints placed upon the user’s work practice. Product requirements specify the desired qualitative characteristics of RE-tools. External requirements are derived from the user’s internal and external environment.
Both frameworks are applied to a specification exemplar which application initiates preparation of the requirements specification for the RE-tool selection. Assessment of the RE-tools’ compatibility to the specified RE-tool requirements is performed using different evaluation techniques. Decision about RE-tool selection is made after summarising all the assessment results.
A prototype tool is developed supporting the frameworks and R-TEA. The R-TEA method is tested in a number of case studies. The findings report on positive trends of the frameworks, prototype and the R-TEA method.

Texto completoResumen
Research findings in requirements engineering (RE) report that software organizations still struggle in establishing processes that lead to proper requirements handling. This leads to the acknowledgement that the adoption of good requirements engineering practices by industry is still not common. Although some initiatives have been made to spread the use of good practices of bespoke RE, the area of market-driven requirements engineering (MDRE) still lacks a contribution in that direction. MDRE is characterized by strong market and strategic orientation, which contrasts with the customer/development organization relationship of bespoke RE. This poses several challenges to software product organizations, such as the need for aligning development activities with organizational and product strategies. In an attempt to help these organizations to realize the benefits of MDRE, this Master Thesis presents the Market-Driven Requirements Engineering Process Model (MDREPM). MDREPM is both a collection of good practices in MDRE, and an assessment tool for organizations to get a snapshot of the current state of their MDRE practices. The assessment intends to reveal problem areas of organization’s requirements process, which can then be worked upon by introducing good practices described in the model. The thesis describes the motivation for creating MDREPM, both from an academia and industry perspectives. In addition, it describes the process of developing the model, from its creation through to its validation within academia and industry. As the series of three case studies conducted indicate, the MDREPM has been shown to be useful for industry practitioners. A unanimous opinion has been found as to the good coverage it provides of issues related to MDRE, and as to its usefulness for driving improvement efforts in requirements engineering.

Texto completoResumen
The thesis starts by examining the environment surrounding UK universities and concludes that external pressures are forcing universities to change. Internal pressures, largely resulting from rapid growth and lack of business systems are also adding to the argument for change. Having concluded that UK universities do indeed need to become more: customer focused; flexible; and efficient - the thesis then puts forward the hypotheses that: • Business Process Re-engineering (BPR) may provide UK universities with a methodology for change; but that the contextual differences between UK universities and business enterprises are so great that existing BPR methodologies couldn't be easily adopted by universities in the UK; • yet, existing methodologies may be used as a basis for creating a methodology designed specifically for UK universities. On reviewing existing BPR methodologies in light of the contextual differences between UK universities and business enterprises, it was concluded that existing methodologies were indeed inappropriate for the university context. The remainder of the thesis documents work carried out in order to develop a more appropriate methodology for the UK university sector. Firstly the results of a quantitative survey aimed at establishing how many UK universities have tried to use Business Process Re-engineering are reported. Secondly the results of a more in-depth, qualitative, investigation are documented. The qualitative research took the form of in-depth interviews with personnel involved in "BPR" exercises in ten UK universities. The drivers for change, the methodologies employed, the problems and the success factors are documented in this thesis. Having analysed the results of this research, a methodology for Business Process Re-engineering in UK universities is developed and documented. Based on feedback received from academics, practitioners and consultants alike, the thesis concludes that the methodology represents a contribution to current knowledge.

Laguda, Alima. "Aggregate assembly process planning for concurrent engineering". Thesis, Durham University, 2002. http://etheses.dur.ac.uk/4144/.
Texto completoResumen
In today's consumer and economic climate, manufacturers are finding it increasingly difficult to produce finished products with increased functionality whilst fulfilling the aesthetic requirements of the consumer. To remain competitive, manufacturers must always look for ways to meet the faster, better, and cheaper mantra of today's economy. The ability for any industry to mirror the ideal world, where the design, manufacturing, and assembly process of a product would be perfected before it is put mto production, will undoubtedly save a great deal of time and money. This thesis introduces the concept of aggregate assembly process planning for the conceptual stages of design, with the aim of providing the methodology behind such an environment. The methodology is based on an aggregate product model and a connectivity model. Together, they encompass all the requirements needed to fully describe a product in terms of its assembly processes, providing a suitable means for generating assembly sequences. Two general-purpose heuristics methods namely, simulated annealing and genetic algorithms are used for the optimisation of assembly sequences generated, and the loading of the optimal assembly sequences on to workstations, generating an optimal assembly process plan for any given product. The main novelty of this work is in the mapping of the optimisation methods to the issue of assembly sequence generation and line balancing. This includes the formulation of the objective functions for optimismg assembly sequences and resource loading. Also novel to this work is the derivation of standard part assembly methodologies, used to establish and estimate functional tunes for standard assembly operations. The method is demonstrated using CAPABLEAssembly; a suite of interlinked modules that generates a pool of optimised assembly process plans using the concepts above. A total of nine industrial products have been modelled, four of which are the conceptual product models. The process plans generated to date have been tested on industrial assembly lines and in some cases yield an increase in the production rate.

A Web Semântica já está deixando de ser uma visão de Tim Berners-Lee para virar uma realidade. Diversos projetos em todo mundo já exploram as potencialidades dessa segunda geração da Web para tornar seu conteúdo processável por máquinas. Infelizmente (ou felizmente!), os computadores não são capazes de desenvolver por livre e espontânea vontade uma linguagem consensual de comunicação. É nesta etapa que entram em cena as ontologias. Conhecida no ramo da filosofia como teorias sobre a natureza da existência, as ontologias têm sido encaradas de maneira consideravelmente diferente no universo computacional. Representam um entendimento comum e compartilhado sobre um domínio específico e têm como o objetivo principal permitir a comunicação entre organizações, pessoas e o uso de metodologias, processos e/ ou métodos bem definidos. Com o aumento de sua importância, o projeto e desenvolvimento de ontologias vêm deixando de ser uma arte para se transformar em um processo de engenharia. Diversas propostas já foram apresentadas para o problema de engenharia de ontologias, muitas delas apoiadas por estudos acadêmicos e industriais. No entanto, é importante notar que nenhuma dessas metodologias - que em muitos casos resumem-se apenas a heurísticas extraídas da experiência de seus autores ou a orientações sobre como alcançar bons resultados - atende por completo aos requisitos potenciais do projeto de uma ontologia. O que se propõe neste trabalho é a unificação de disciplinas e atividades oriundas de metodologias distintas em um framework de processos abrangente, entitulado KUP - Knowldge Unified Process, que permite um adequado projeto e desenvolvimento de ontologias e bases de conhecimento. Entende-se como um processo um conjunto de atividades e resultados associados a essas atividades com o objetivo de garantir a geração de um produto final, seja este produto um software, uma ontologia ou uma ontologia associada a sua base de conhecimento. A unificação deste processo segue as melhores práticas em engenharia de software existentes na indústria e é apoiada por um framework de avaliação de metodologias consolidado na academia. Foram realizados dois estudos de caso para este framework de processos, um envolvendo o desenvolvimento de uma solução de gestão de conhecimento em segurança da informação e outro envolvendo a integração de uma ferramenta de gestão de competências para ambientes de educação a distância.
The Semantic Web is now a reality. Several projects all around the world are already using tools technologies developed to support the second generation of the Web to provide machine-processable content for software agents, web services and applications. However, computers can not agree on a consesual language by themselves. Ontologies can be used as a way to provide this shared conceptualization, making posssible the desired communication among organizations, people and apllications. Several proposals have been already presented regarding ontology engineering - many supported by academic and industrial case studies. However, none of them encompasses all the requirements identified for an ontology construction project. This work describes the unification of different features extracted from those methodologies to build a process framework named KUP - the Knowledge Unified Process. This unified process is based on several industry best practices and on a well accepted ontology methodology evaluation framework. Two case studies were developed so as to support and validate this process framework. The first was the development of a semantic web solution for security information knowledge management and the second one was the integration of a skill management tool to a learning management system, through ontologies.

Continuous manufacturing offers a number of operational and financial benefits to pharmaceutical companies. This research examines the critical blending step for continuous pharmaceutical manufacturing and the characteristics of continuous downstream pharmaceutical manufacturing systems. Discrete element method (DEM) simulations were used to develop novel insights into the mechanism of mixing for continuous blending of cohesive pharmaceutical powders and to examine the effects of particle properties, blender design and operating conditions on blend homogeneity. To place continuous blending into the context of pharmaceutical manufacturing, the scope of the analysis was expanded to process system models of continuous downstream pharmaceutical manufacturing. DEM simulations were used to study the mechanisms of mixing in the continuous blending of pharmaceutical powders. Diffusive mixing from the avalanching particles appears to be the dominant mechanism of mixing in both the axial and radial direction for the double helical ribbon blender. This result can guide the development of future continuous pharmaceutical powder blenders by optimizing the mixing elements to increase the amount of particles transported to a position where they can avalanche/flow and diffusively mix. A range of particle properties, blender designs and operating conditions were examined for their effects on flow behavior and blend homogeneity. Three particle properties were examined: particle size, polydispersity and cohesive force.
(cont.) Particle size was observed to be positively correlated to both flow rates and blend homogeneity. Polydispersity had no effect on flow rate and was negatively correlated to homogeneity. Cohesive force was negatively correlated to flow rate and had little to no effect on homogeneity. Two modifications of blender design were analyzed: changes in blender size and changes in shaft design. Blender size was observed to be positively correlated to flow rate and negatively correlated to homogeneity. The paddle shaft designs created a more homogeneous powder blend than the double helical ribbon shaft. Two operating parameters were also studied: rotation rate and fill fraction. Rotation rate was positively correlated to both flow rate and homogeneity. Fill fraction had the interesting result of being positively correlated to the absolute flow rate, but negatively correlated to the fill mass normalized flow rate. In addition, fill fraction has a clear negative correlation to homogeneity above fill fractions of 0.55, but is inconsistent for fill fractions lower than this. This research on particle properties, blender designs and operating conditions will help to guide the operation of continuous pharmaceutical blenders and the design of continuous pharmaceutical manufacturing systems. Process simulations comparing model batch and continuous downstream pharmaceutical manufacturing systems have quantified some of the potential size, cost and performance benefits of continuous processes. The models showed significant reductions in process equipment sizes for continuous manufacturing particularly in the blending step.
(cont.) This reduction in equipment size translates to capital cost (CAPEX) savings for both the continuous process equipment and manufacturing facilities. The steady state operation of continuous processing also reduces the labor requirements and gives the continuous processes an operating cost (OPEX) advantage over batch processes. This research has contributed to the understanding of continuous pharmaceutical powder blending and quantified some of the benefits of continuous downstream pharmaceutical manufacturing. This work is being continued by the Novartis-MIT Center for Continuous Manufacturing whose work is providing the foundation for future industrial scale pharmaceutical continuous manufacturing systems.

It has always been the case that talented individuals with an innate understanding of their subject have been able to produce works of outstanding performance. The purpose of engineering science is to define ways in which such achievements can be made on a regular,predictable basis with a high degree of confidence in success. Some tools, such as computers, have enabled an increase in speed and accuracy, whilst others have given a dramatic increase in the insight into the operation or behavior of materials; the electron microscope for instance. Still others have enabled the creation of devices on a scale unimaginable to our predecessors, Molecular Beam Epitaxy for example. This work is the product of the availability of an understanding of complex theory on microwave transistor operation, significant increases in mathematical processing and data handling, and the assembly of a ‘tool’ that not only allows the measurement of high frequency waveforms, but their manipulation to simultaneously create the environments envisioned by the design engineer. It extends the operation of previous narrow band active load pull measurement systems to 40GHz and importantly facilitates the design of high efficiency modes at X band. The main tenant of this work is to propose that rather than the linear approach of characterisation, design, test, re-iterate, that has been the standard approach to MMIC design to date, the first three stages should be integrated into a single approach which should obviate the need for design reiteration. The result of this approach should be better performance from amplifier designs, greater probability of success first time, and lower costs through less wafer real estate being consumed and fewer sign ‘spins’.

Texto completoResumen
The subject of this Thesis is that of engineering design. The primary objective of the Thesis is to produce a model of the engineering design process. This model represents the way engineering design takes place regardless of the scale of the design project or the type of object which is being designed. The model is consensus based and has been produced through an extensive review and analysis of literature, (the literature review being completed in 1987) taken both from the field of engineering design and from disciplines concerned with related issues. In addition to the review and analysis of literature, a large number of interviews and consultations were undertaken with design experts and designers. The Thesis is divided into three main sections. The first section is concerned with a discussion of the evidence gained through the processes of literature review and interview/consultation. The second with a description of the model and its origin. The third is concerned with a description of the means by which design takes place. The model is essentially sequential, but has also incorporated the major elements of process type models of design. By demonstrating that an accommodation is possible between these two design theory approaches, an advance has been made into the understanding of the way in which design takes place. The model consists of sequential stages each of which characterises a major type of activity wi thin the process and which describe the design process from the initial perception of need through to the production of the finalised design configuration. Designs are developed by passing iteratively through these stages. Solutions and partial solutions, along with other design information are stored within the Blackboard. The means by which designs are developed is also examined in terms of the type of aid they give the designer, and their informatie relationship to the design process.

Previous issue date: 2007A reutilização de software o processo de criar sistemas através de artefatos existentes, ao invés de desenvolvê-los do zero é um aspecto chave para melhorias em qualidade e produtividade no desenvolvimento de software. Qualidade pode ser melhorada por reutilizar todas as formas de experiência, incluindo produtos e processos. Por outro lado, a produtividade pode ser aumentada por utilizar experiências existentes. Entretanto, esse processo é mais efetivo quando sistematicamente planejado e gerenciado no contexto de um domínio especifico, onde as aplicações compartilham funcionalidades comuns. Neste cenário, a Engenharia de Domínio a atividade de coletar, organizar e armazenar experiências anteriores na construção de sistemas ou partes de sistemas, de um domínio particular, na forma de artefatos reutilizáveis tem sido vista como um facilitador para obter os benefícios desejados. No entanto, os processos existentes de engenharia de domínio apresentam problemas cruciais, como, por exemplo: eles não cobrem os três passos da engenharia de domínio, a saber, análise do domínio, projeto do domínio e implementação do domínio; além de não definir de forma sistemática as atividades, as sub-atividades, os papéis, as entradas e as saídas de cada passo. Assim, este trabalho define um processo sistemático para realizar a engenharia de domínio, baseado no estado da arte da área, incluindo os passos de análise, projeto e implementação do domínio. Essa definição foi embasada por surveys detalhados sobre reutilização de software e processos de reutilização, cobrindo pesquisas informais, estudos empíricos e relatos de empresas. Esta tese primeiro apresenta os resultados desses surveys e, em seguida, descreve o processo proposto discutindo suas atividades, sub-atividades, entradas, saídas, princípios, guidelines e papéis. Por fim, são discutidos os resultados de um estudo experimental para análise da viabilidade do processo proposto em um projeto de engenharia de domínio

"Discover Mechanical Engineering" (DME) is a student-run Freshman Pre-Orientation Program at the Massachusetts Institute of Technology which, in the time since its inception in 2002, has developed into a popular, professional, and well-organized pre-orientation program MIT. Yet despite its success, it routinely experiences difficulties with respect to personnel and timeframes, both of which continually threaten the well-being of the program. It appears, however, that such difficulties are not a result of the students' motivational level, since all of DME's student volunteers contribute a great deal of time to the program. Rather, the problem may be that DME student leaders (and their supporting volunteers) are attempting to run the program prior to having taken MIT's Product Engineering Process course (also known as 2.009), a required senior-year mechanical engineering course which is expressly designed to teach students how to manage projects similar to DME. This course teaches tools most useful for the management of personnel and of time - the very areas which DME seeks to improve - through the use of Gantt charts, delineation of the project's critical path, and sundry other methods.
(cont.) It is reasonable to believe that bringing a Product Engineering Process methodology to DME would help rectify existing problems, thereby benefiting the program as a whole. This thesis studies the DME program, examines PEP approaches as potential solutions to recurring problems, and suggests several areas for further improvement of DME as a whole.

Production systems typically involve significant uncertainty in their operation due to either external or internal sources. The existence of uncertainty transforms conventional deterministic process models to stochastic/parametric problems, the solution of which requires the application of specialized optimization techniques. The main objective of this thesis is to develop suitable algorithms and numerical techniques for the efficient solution of process engineering problems involving uncertain parameters. Based on modelling issues regarding uncertainty classification (deterministic and stochastic uncertain parameters) and design objectives with respect to uncertainty (fixed degree of flexibility and optimal degree of flexibility), a unified multiperiod/stochastic two-stage optimization formulation is proposed and a decomposition based algorithmic procedure is developed for its efficient solution. The proposed algorithm forms the basis for addressing process design problems, planning and scheduling problems and problems related to behavioural analysis under uncertainty. For batch plant design problems involving uncertainty in the description of process parameters such as transfer coefficients, kinetic constants, etc., as well as variability of external parameters such as product demand, economic cost data etc., the exploitation of the special structure coupled with the relaxation of feasibility requirement regarding product demands enables the transformation of the stochastic two-stage programming problems to a single optimization model where the structure of the deterministic problem is fully preserved. For the case of continuous size of equipments, an efficient global optimization procedure is proposed, whereas for the case of discrete equipment sizes the algorithm reduces to the solution of a mixed integer linear programming problem. For short term production planning and long-range planning problems including capacity expansion options, the application of the proposed approach results in the optimal production plan (i. e. process utilization levels, purchases and sales of materials) and/or an optimal capacity expansion policy that maximize an expected profit and ensure an optimal level of future feasibility. Finally, an attempt to address the question of the future "value" of uncertainty is presented based on the concept of value of perfect information. It is shown that the proposed algorithmic developments can be effectively extended to include both the solution of the here-and-now and the wait-and-see models in order to analyze and integrate the

Nous développons des modèles de processus pour décrire et gérer efficacement la conception innovante, en suivant la méthodologie DRM. D'abord, nous présentons un modèle descriptif de la conception innovante. Ce modèle reflète les processus fondamentaux qui sont utiles pour comprendre les différentes dimensions et étapes impliqués dans la conception innovante. Il permette aussi de localise les possibilités d'innovation dans ce processus, et se focalise sur les facteurs internes et externes qui influencent le succès. Deuxièmement, nous effectuons une étude empirique pour étudier la façon dont le contrôle et la flexibilité peuvent être équilibrés pour gérer l'incertitude dans la conception innovante. Après avoir identifié les pratiques de projets qui traitent de ces incertitudes en termes de contrôle et de flexibilité, des études de cas sont analysés. Cet exemple montre que le contrôle et la flexibilité peuvent coexister. En se basant sûr les résultats managériaux issu de cette étude empirique, nous développons un modèle procédurale de processus et un modèle adaptatif à base d’activité. Le premier propose le cadre conceptuel pour équilibrer l'innovation et le contrôle par la structuration des processus au niveau du projet et par l'intégration des pratiques flexibles au niveau opérationnel. Le second modèle considère la conception innovante comme un système adaptatif complexe. Il propose ainsi une méthode de conception qui construit progressivement l'architecture du processus de la conception innovante. Enfin, les deux modèles sont vérifiées en analysant un certain nombre de processus et en faisant des simulations au sein de trois projets de conception innovanteWe develop a series of process models to comprehensively describe and effectively manage innovative design in order to achieve adequate balance between innovation and control, following the design research methodology (DRM). Firstly, we introduce a descriptive model of innovative design. This model reflects the actual process and pattern of innovative design, locates innovation opportunities in the process and supports a systematic perspective whose focus is the external and internal factors affecting the success of innovative design. Secondly, we perform an empirical study to investigate how control and flexibility can be balanced to manage uncertainty in innovative design. After identifying project practices that cope with these uncertainties in terms of control and flexibility, a case-study sample based on five innovative design projects from an automotive company is analyzed and shows that control and flexibility can coexist. Based on the managerial insights of the empirical study, we develop the procedural process model and the activity-based adaptive model of innovative design. The former one provides the conceptual framework to balance innovation and control by the process structuration at the project-level and the integration of flexible practices at the operation-level. The latter model considers innovative design as a complex adaptive system, and thereby proposes the method of process design that dynamically constructs the process architecture of innovative design. Finally, the two models are verified by supporting a number of process analysis and simulation within a series of innovative design projects

Approved for public release; distribution is unlimitedThe application of systems engineering methodologies to the creative process provides opportunities to improve the creative capabilities of individuals and organizations. Through creativity and systems engineering research, the creative process is equated to the systems engineering process. This allows creativity itself to be defined as a system. Defining creativity as a system permits the analysis of the creative process and the construction of a systems engineering based process model for creativity. Process based creativity theories are decomposed and reformulated into a process flow that acknowledges the iterative and recursive nature of the creative process. The derived process flow is then integrated with systems engineering process elements to construct a process model for creativity. The production of a systems engineering derived process model for creativity allows future opportunities to improve that process model by incorporating new creativity research and/or additional influences on creativity, increasing the fidelity of the model. The proposed process model also invites future research into the efficacy of the model. Through the use of systems engineering, creativity research may be incorporated and refined to build an evolving process model for creativity.

This thesis provides an extensive overview of the issues involved in adopting a knowledge based approach to the development of an integrated process design environment. The majority of the work described requires a good understanding of topics from several research areas outwith mainstream process engineering. The topics covered include logic, graph theory, knowledge representation, and theories of comprehension in cognitive science. Introductory reviews of these subjects are provided in order to make the thesis understandable to an engineering audience. The thesis consists of four main sections. The first section consists of a critical review of previous attempts to develop integrated design systems using database technology. The section highlights the problem of the use of such systems in terms of data and knowledge integrity. A novel AIP (Appropriate and Incremental Parallelism) systems engineering framework is proposed along with a long term research framework to investigate the use of knowledge representation techniques to implement this design methodology. The second section provides a review of the basic aspects of graph theory, logic and production systems that are essential to understanding the rest of the work. The third section describes the development and use of rule based techniques, blackboard systems, and object oriented/frame based systems. A novel representation system, (Combined Logic and Procedures - CLAP), is described that is specifically designed to represent the various types of information needed in a process design environment. Drawing on these developments, the fourth section provides an extensive review of the many problems associated with the use of production and frame based systems. This is followed by a review of more advanced ideas on theories of comprehension in cognitive science. In particular the study of conceptual categorisation and mental models is discussed in some detail. The preliminary development of a system, Designer's Assistant, is then described that attempts to embody these ideas in a working system. The main conclusion of the work is that current knowledge representation techniques are far from adequate in terms of being able to provide the tools needed to develop an intelligent design environment. The work described in the latter half of the thesis indicates that considerable research remains to be done.

Texto completoResumen
Knowledge Based System (KBS) development is a difficult and challenging task, in particular in knowledge intensive domains. The traditional view of knowledge engineering is one of mining experts' knowledge and somehow transforming it into a machine usable form. This process, in general, suffers from insufficient or misconstrued representation of experts' problem solving behaviour. It is also unstructured and unduly biased at an early stage by design and implementation issues - normally in the form of incremental prototyping. We believe that both knowledge acquisition and KBS development for real life applications will require a 'structured' approach. This approach should harness a KBS developer's ability in extracting knowledge and developing systems. The structure should also be sufficiently flexible to allow the knowledge engineer to use his sense of creativity in developing a KBS. This thesis puts forward such a structured approach, in which KBS development is carried out in an engineering fashion. A process in which the worker is provided with an environment for developing knowledge based systems as an engineering process, as opposed to that of an artform or crafting. The main emphasis of this work is that part of the process which deals with the analysis and design phases in developing KBS. The analysis is performed at an 'epistemological' level, not coloured by design or implementation issues. The output of this phase captures both an expert's problem solving capability, and the business constraints placed upon the intended system. This is then used by the design process in order to create an optimal, workable, and elegant design architecture for the ultimate system.

Dealing with security is a central activity for todays organizations. Security breaches impact on the activities executed in organizations, preventing them to execute their business processes and, therefore, causing millions of dollars of losses. Security by design principles underline the importance of considering security as early as during the design of organizations to avoid expensive fixes during later phases of their lifecycle. However, the design of secure business processes cannot take into account only security aspects on the sequences of activities. Security reports in the last years demonstrate that security breaches are more and more caused by attacks that take advantage of social vulnerabilities. Therefore, those aspects should be analyzed in order to design a business process robust to technical and social attacks. Still, the mere design of business processes does not guarantee that their correct execution, such business processes have to be correctly implemented and performed. We propose SEcure Business process Engineering (SEBE), a method that considers social and organizational aspects for designing and implementing secure business processes. SEBE provides an iterative and incremental process and a set of verification of transformation rules, supported by a software tool, that integrate different modeling languages used to specify social security aspects, business processes and the implementation code. In particular, SEBE provides a new modeling language which permits to specify business processes with security concepts and complex security constraints. We evaluated the effectiveness of SEBE for engineering secure business processes with two empirical evaluations and applications of the method to three real scenarios.

Texto completoResumen
In System Test, there is currently no common test procedure validation process across commercial, civil and government programs. Enterprise processes simply state to perform verification and validation. The method of satisfying that requirement is left to each individual organization and/or program. The process is generic in order to support an Enterprise of products that can vary from military weapons to commercial satellites.
A common test procedure validation process can be adopted which is platform and program independent to provide more guidance than the top level Enterprise process. The method of allowing each System Test program to define their own validation process results in inconsistencies between programs. Important Lessons Learned which could result in an improved validation process for a particular program are not captured. Costly rework is incurred without standardization. The root causes for Test Procedure rework fall in three common categories as shown in Table 1.
Program X is an example of a program which does not follow a standard validation process. Therefore their process is incomplete and results in significant rework. This document will limit its scope to focus on standardizing Program X's process to the validation process currently used by the majority of programs in System Test. The goal is to develop a standard procedure and in tum reduce the number of validation process issues (rework) currently plaguing Program X. During this process, techniques from Lean and Quality courses will be utilized.

The micro embossing process on polymethylmethacrylate (PMMA) is demonstrated experimentally to be a useful process to produce micro fluidic and optical devices. Because this process is a one step thermoplastic deformation process, it is possible to reach high production rates and low cost in manufacturing compared to the standard clean room processes. Currently, the research about this process is still on the feasibility level, with not a quantitative work to optimize the process parameters and assure product quality. In this thesis, an experimental study on process window and variation of Micro Embossing is presented. This study includes the design and manufacturing of an embossing die, the development of an embossing product quality assessment protocol, the process window characterization and the process variation identification. The research results based on the experimental set up in this thesis show that we should apply constant 800N embossing force at an embossing velocity of 1000N/min in order to obtain well formed parts to maintain low process cycle time.
(cont.) An embossing temperature of 120°C and de-embossing temperature of 55°C are shown to be the optimal embossing condition to yield good replication and repeatability. These embossing parameters operating window can change with the variation of working piece material, die material and die design.
