Computer integrated hybrid modeling support systems for enterprise management decision making in concurrent engineering

The enterprise management decision making (EMD) in concurrent engineering (CE) is first discussed. Secondly, the role of modeling support in CE is described. By analyzing the advantages and disadvantages of four commonly used modeling methods, namely, Petri nets, neural network, interactive modeling and OR, we show the importance of computer integrated hybrid modeling support systems. To build such a system, a formal description of a general model is presented and four basic modes of integration upon the general model are introduced. Finally, a framework of the system is proposed.
