Enterprise modelling is concerned with representing and assessing various aspects of an enterprise in order to better understand, restructure or design enterprise operations. It is the basis of business process re-engineering, a major concern in most companies in industrial countries, and the first step to advising enterprise integration. Enterprise integration is a rapidly developing technical field which looks at the interworking of business applications. It has already provided proven solutions for system interconnection, electronic data interchange, product data exchange and distributed computing environments. This text combines these two methodologies and advocates a systematic engineering approach called enterprise engineering, for modelling, analysing, designing and implementing integrated enterprise systems. It presents the essential set of knowledge, which every industrial engineer and postgraduate student should possess to face industrial requirements for enterprise modelling and integration. Three main themes are explored in this book. The most significant enterprise modelling and integration architectures are presented.Enterprise modelling principles are then introduced and state-of-the-art methods to model various aspects of an enterprise system are discussed and compared. The final part is devoted to enterprise integration principles and techniques.

Modern manufacturing systems must be engineered as any other complex systems, especially in the context of their integration. The book first presents the all-embracing concept of the Extended Enterprise as way of inter-enterprise integration. It then focusses on Enterprise Engineering methods and tools to address intra-enterprise integration using a model-based approach. Business process modelling and re-engineering isssues are particularly discussed and tools presented. Formal specification and Petri net-based analysis methods for manufacturing systems complete the set of tools for Enterprise Engineering. Coordination and integration issues of manufacturing systems and their business processes are then covered and examples of integration platforms presented. Finally, standardization and pre-standardization issues related to enterprise modelling and integration conclude the book.

M. Silva Significant changes have been occurring in industrialized countries since the Second World War. Production is moving towards sophisticated high qUality products, economy of scale has been replaced by economy of scope, jerky demands are progressively replacing steady demands, and competi tiveness is becoming a worldwide phenomenon. These trends require highly automated manufacturing systems with small set-up times and high flex ibility. As a consequence, implementation and running costs of modem manufacturing systems are drastically increasing, whereas their fields of application remain limited, and every day become even narrower, which increases the risk of early obsolescence. This is the reason why designers are trying to improve the preliminary design phase, also known as the 'paper study phase'. The preliminary design phase includes, but is not limited to, the func tional specification, and the evaluation of the system. Many tools exist to support the functional specification of manufactur ing systems. IDEFO is one of these tools. It leads, using a top-down ap proach, to a precise functional description of the required system. However, its use cannot be extended further. In general, the evaluation starts with a modeling step, which depends on the evaluation tool used, and ends by applying the model to find out its main dynamic characteristics. Two main approaches can be used to perform this task, namely simulation and math ematical approach. Using simulation, the modeling tool is either a classical computer language, or a simulation language.
