A GENERAL APPROACH OF BUILDING VIRTUAL PRODUCTION SCHEDULING SYSTEM FOR CONTINUOUS INDUSTRIES IN CIM ENVIRONMENT

A general production scheduling system in CIM environment for continuous industries is introduced in this paper. With this approach, we can build a virtual production and scheduling system for special continuous production plant conveniently. A general model of most continuous production units is applied in this paper, based on which a general object class of integrating production simulation and logical analysis is provided. This object class is established with OOP (Object Oriented Programming), with integration of some logical analysis method based on hybrid dynamic system theory. The structure of this object class is open and embedding. External production simulation module can be linked to the object. By this means, a system of production prediction, analysis and scheduling for special units can be established. Both stable simulation module and dynamic simulation module can be used in this approach. This makes it possible to use many existed simulation softwares. Thus the software reusability of this approach is high. Several simple rules are need when making use of this general approach in special plant.
