A Reconfigurable Assembly System Modeling Method Based on Agent-based Timed Colored Petri Nets

Abstract

A reconfigurable assembly system modeling method based on Agent-based timed colored Petri net in the field of automatic control and artificial intelligence technology, aiming at the complexity, reconfiguration, intelligence and autonomy of reconfigurable assembly system Features: Based on the classification of assembly resources, the internal behavior of assembly resource Agent is encapsulated, the ATCPN model of assembly resource Agent is established, and the reconfigurable assembly unit ATCPN model is synthesized through transition transition. According to the logical relationship between each reconfigurable assembly unit, the message transmission relationship of the whole system is determined, and on this basis, the rapid reconfiguration of the assembly system is realized. Analyze the performance indicators of the ATCPN model of the reconfigurable assembly system, and propose the mapping rules from the AUML model to the ATCPN model and the interactive protocol modeling method based on ATCPN, and the deadlock existing in the model can be solved by introducing the corresponding multi-agent interactive protocol model and conflict.

Description

technical field [0001] The invention relates to a reconfigurable assembly system modeling method based on an Agent-based timed colored Petri net, which belongs to the field of automatic control and information technology of production lines. Background technique [0002] Modeling of reconfigurable assembly systems is one of the most basic issues in the research of reconfigurable assembly systems. By constructing a dynamic stochastic model that accurately reveals the connotation of reconfigurable assembly systems, the uncertainty of the market, the diversity of customer orders and the The randomness of various unpredictable factors in the manufacturing process is analyzed, simulated, optimized and controlled. According to the existing literature, most of the current modeling methods for reconfigurable assembly systems are to establish the model of the manufacturing system from a certain point of view and at a specific level - function model, information model or dynamic model...
