A Virtual Model of Manufacturing System Based on Hybrid Automata

In view of the current virtual manufacturing system models lack the expression of the static structure affected by dynamic manufacturing process, which leads to the virtual model cannot express the change of the physical manufacturing system accurately, then affects real-time analysis of manufacturing system adversely. A fusion model combines the static structure and dynamic manufacturing process is established based on hybrid automata, which describe the manufacturing system static structure by hybrid automata state and the dynamic process by hybrid automata state transition event, then describe how the dynamic process acts on the static structure of the system by different event-driven state transition. In the end, by the implementation of the former work to modeling a manufacturing system from task assignment to exception handling.
