International Telemetering Conference Proceedings / October 30-November 02, 1989 / Town & Country Hotel & Convention Center, San Diego, California / Computer Sciences Corporation, Realtime Data Systems Center has developed, integrated, tested, and delivered several large telemetry systems to various ranges over the past eight years. One key to the success of these systems has been the ability to build on a software base to meet unique range processing requirements for aircraft, missiles, and related weapons systems. Reusable software means reduced procurement and life cycle costs. The ability to successfully reuse software for new systems with new requirements lies not only in the fundamentals of modular system design, but in the ability of the people to comprehend the design, and adapt the software to new requirements. As advanced telemetry processing needs meet reduced budgets, the successful systems integrator will be relying more and more on an ability to adapt existing systems to meet new challenges.

"Concepts in manufacturing such as CIMS (Computer Integrated Manufacturing Systems), JIT (Just In Time), Lean Production, Virtual Manufacturing, and Flexible Fixturing have been proposed to meet the fundamental requirements of manufacturing - decrease the cost and satisfy the needs of customers. Fast fixture generation and fixture reusability are essential in the current manufacturing environment. The dissertation focuses on the models, methods, and algorithms for fixture synthesis and variation that satisfy the functional requirements specified by on-site industrial engineers. With the reusability of a fixture base combined with variation of other fixture components, fixture configuration can be rapidly adapted and accommodated to the new workpiece. The dissertation presents methods and algorithms for fixture base synthesis, which directly result in fixture reusability. Optimization functions are derived based on engineering requirements due to the mass production nature of automotive parts. Specific optimization algorithms are developed and their complexities, compared to other alternatives, are comprehensively evaluated according to different optimization functions. The fixture variation and reusability provide an engineering tool to rapidly generate and validate fixtures in production planning stage. It applies scientific reasoning methodology in combination with best knowledge of fixture designs, which heavily relies on designers' manufacturing knowledge and experience. It also provides means to bridge the gap between CAD and CAM integration and therefore reduces the new product and production development cycle time and cost while maintaining the quality of fixtures."

<p>Component-based Software development is a promising way to improve quality, time to market and handle the increasing complexity of software management. However, The component-based development is still a process with many problems, it is not well de_ned either from theoretical or practical point of view. This thesis gives a brief overview of Component-Based Software development and starts with brief historical evolution followed by a general explanation of the method. A detailed discussion of the underlying principles like components, component framework and compent system architecture are then presented. Some real world component stadards such as .net framework, CORBA CCM and EJB are given in detail. Finally, simple fille-sharing-program based on Apache's Avalon framework and another one based on .net framework are developed as a case study.</p>

O reúso de software enfrenta inúmeras barreiras gerenciais, técnicas e culturais na sua adoção, e a definição da estrutura de ativos reutilizáveis de software é uma dessas barreiras técnicas. Para solucionar isso, o Reusable Asset Specification (RAS) é um padrão de facto proposto pela OMG. Uma especificação como o RAS define e padroniza um modelo de ativos (assets) reutilizáveis, e é a base para a construção e para o uso de um repositório de ativos que apoia a reutilização de software. No entanto, para ser adotado na prática, o RAS necessita resolver suas lacunas através da sua extensão e da definição de informações complementares. Essas lacunas estão detalhadas neste trabalho. Solucionando estas lacunas, o RAS torna-se útil para auxiliar efetivamente na padronização do empacotamento dos ativos reutilizáveis e para guiar a estrutura do repositório de reutilização de software. Alguns trabalhos anteriores já responderam parcialmente essa questão, porém eles atendiam propósitos muito específicos, não possuíam uma ferramenta de apoio ou não haviam sido avaliados em contexto real de (re)uso. Esse trabalho propõe o Software Profile RAS (SW-RAS), uma extensão do Profile de componentes do RAS, que propõe soluções para diversas de suas lacunas, incluindo informações úteis e artefatos relevantes apontados na literatura, baseados em outros modelos de ativos reutilizáveis, em outras extensões do RAS e na experiência do processo de reúso no desenvolvimento de software. Particularmente, o SW-RAS estende as categorias de classificação, solução, uso e ativos relacionados, cujos detalhes estão descritos no texto. Visando à experimentação da proposta através de um estudo de caso, desenvolveu-se o Lavoi, um repositório de ativos reutilizáveis baseado no SW-RAS, que foi avaliado num ambiente real de reutilização e desenvolvimento de software de uma grande companhia pública de TI. Uma descrição deste processo de avaliação em um contexto real é também apresentada neste trabalho. A principal contribuição desta dissertação é a proposta, a avaliação e a consolidação de uma extensão do RAS que atende várias de suas lacunas e é suportada por uma ferramenta de software livre. / The software reuse faces numerous managerial, technical and cultural barriers in its adoption, and the definition of the structure of reusable software assets is one of these technical barriers. To solve this, the Reusable Asset Specification (RAS) is a de facto standard proposed by OMG. A specification such as the RAS defines and standardizes a reusable asset model, and it is the foundation for the construction and for the use of an asset repository that supports the software reuse. However, for being adopted in the practice, the RAS needs to solve its lacks through its extension and the definition of complementary information. These lacks are detailed in this work. Solving these lacks, the RAS becomes useful to help effectively in the standardization of packaging reusable assets and to guide the structure of the software reuse repository. Some previous works have already partially answered this question, but they attended very specific purposes, did not have a support tool or have not been evaluated in a real context of (re)use. This work proposes the Software Profile RAS (SW-RAS), an extension of the component Profile of RAS, which proposes solutions for its various lacks, including useful information and relevant artifacts pointed out in the literature, based on other reusable asset models, on other RAS extensions and on the experience in the reuse process at software development. Particularly, the SW-RAS extends the categories of classification, solution, usage and related assets, whose details are described in the text. Aiming at the experimentation of the proposal through a case study, the Lavoi was developed, a reusable asset repository based on the SW-RAS, which is was evaluated in a real environment of reuse and software development of a large public IT company. A description of this evaluation process in real context is also presented in this work. The main contribution of this dissertation is the proposal, the evaluation and the consolidation of an extension of RAS that addresses several of its lacks and is supported by a free software tool.
