摘要：A new generation of industrial revolution represented by intelligent manufacturing has come. Multi-product and small batch have become trend in market demands nowadays. Cyber-physical production system is a useful tool to meet this trend by performing tasks intelligently. Since cyber-physical production system performs tasks intelligently and autonomously, tasks and resources should be defined in standardized form in order to be identified and analyzed. Thus, how to define and analyze tasks and resources become the prerequisite for the operation of cyber-physical production system. In this article, a tasks and resources matching and analysis method is proposed for cyber-physical production system. First, the form of process knowledge base is designed, and the method for tasks and resources definition and matching is discussed. Next, the model of system operation logical based on colored Petri net and processing route generation algorithm is built. The parameters forecast method for non-standard processes is designed based on backpropagation neural network. Finally, implementation mechanism and effectiveness of the method are verified by a prototype system.
