This work addresses the problem of finding an improved solution to Computer Integrated Manufacturing (ClM) Architecture and Systems Design. The current approaches are shown to be difficult to understand and use, over complex. In spite of their complexity of approach they lack comprehensiveness and omit many factors and dimensions considered essential for success in today's competitive and often global market place. A new approach to ClM Architecture and Systems Design is presented which offers a simpler, more flexible and more robust format for defining a particular ClM System within a general architectural framework. At the same time this new approach is designed to offer a comprehensive and holistic solution. The research work involved the investigation of current approaches and research and development initiatives focusing particularly on the CIM-OSA and GRAI Integrated methodologies in the field of ClM Architecture. The strengths and weaknesses of the various approaches are examined. Developments in other related fields including manufacturing systems, manufacturing management, information technology and systems generally have been investigated regarding their relevance and possible contribution to an improved solution. The author has built on his practical experience in creating, designing and managing the implementation of a global CIM system. The authors work on several publicly funded collaborative research and development projects relevant to the problem area is described. These include CIM-OSA, IMOCIM and TIQS projects. In the latter two projects the author was instrumental in developing the methodological approach based on a systems approach to business processes in connection with the design of quality and manufacturing systems. Both of these projects have contributed to this work. The author has also participated in the global IMS programme as a rapporteur for the European Commission and this helped to provide a global perspective on the problems of manufacturing companies as they attempt to compete in a world wide market place. The results of this work provide the basis for a radically improved approach to ClM Architecture and Systems Design based on the holistic view of an enterprise. The approach developed supports the business process view of an enterprise; addresses the people and organisational aspects; leads to ClM solutions focused on meeting enterprise goals; and is able to deal with a significantly increased scope and complexity compared with existing methods yet is easily understood and more simple to simple to apply than current approaches.

Esta dissertação analisa a utilização do modelo de dados padronizado pela norma IEC 61970 (CIM), tida como uma ferramenta para troca de informações cadastrais e operacionais entre empresas de energia elétrica, com sistemas computacionais de diferentes fabricantes. O propósito deste padrão é criar um mecanismo para troca de informações baseado em XML, denominado de CIM/XML – um formato, especificamente, utilizado pelos Centros de Controle de Energia Elétrica para troca de dados. Os modelos de dados do padrão IEC 61970 são apresentados, bem como a avaliação do CIM/XML como uma ferramenta de interoperabilidade de dados entre empresas de energia que apresentam bases de dados de diferentes modelagem e implementação. Um dos méritos deste modelo, além de fazer uso de uma tecnologia aberta (XML) disponível em qualquer tipo de computador, e que possibilita armazenar e transferir não só dados cadastrais de equipamentos, mas também dados de topologia da rede, curvas de carga, programação de geração, saídas programadas de equipamentos, bem como medições de sistemas SCADA, indicações de estado e alarmes. Possibilita ainda armazenamento de resultados de simulação, tais como resultados do programa de fluxo de potência. Adicionalmente, é apresentado em detalhes informações sobre: a implementação do modelo lógico orientado a objetos do CIM, numa base de dados relacional; os registros de equipamentos e a topologia de um trecho de linha de sub-transmissão aéreo e subterrâneo; as informações (exportadas e importadas no formato CIM/XML) inseridas na base de dados, e a geração do documento CIM/XML. / This dissertation provides an analysis about the application of a data model based on IEC 61970 (CIM) standard – a tool for exchanging operational and equipments information among different Electrical Power Utilities' computing systems. The purpose of this standard is to create a mechanism for information exchange using XML, called CIM/XML – a format specifically used by Electrical Power Utilities' Control Centers for data exchange. The IEC 61970 standard-based data models is presented as well the evaluation of CIM/XML as a tool for data interoperability among Electrical Power Utilities' databases, that uses different modeling and implementation approaches. The benefit of this model – besides of using a open standard technology (XML) that can be found on any type of computer – is the capability of store and transfer information not only from equipments, but also from network topology, load flow curves, generation scheduling, equipments outages, SCADA system measurements, status indication and alarms. It also enables the storage of simulation results, such as the power flow bus voltage and lines loads. Additionally, is also provided highly detailed information about: the CIM object-oriented model implementation mapped to a relational database; the records of equipments and topology of an aerial and underground subtransmission line section; the information (exported and imported using CIM/XML format) included in the database, and the CIM/XML document generation.
