Optimization and control for mixed batch/continuous processes based on hybrid time Petri net

This paper address an efficient way to maximize the throughput of mixed batch/continuous process based on hybrid time Petri nets. The scheduling problem of process is mapped as the solution of the optimal regional state sequence in HTPNs. The transition firing decision model is developed according to the enabling and firing rules, and the scheduling algorithm based on backtracking method to search the approximately optimal feasible scheduling policy is presented. In addition, algorithm is illustrated through case studies.
