Integration of decisional and physical systems in the design of manufacturing systems

The design of Computer Integrated Manufacturing Systems is becoming more and more complex. This complexity is the result of the high degree of automation of such systems and the need for integrating various components (technical, economic, social and human) and various functions. Considering the life cycle of a manufacturing system, we can bring out several steps : analysis/ design, development, implementation, operating. The experience shows the importance of the analysis/ design phase on the cost of following task if we can use a method.
