Holonic Reconfiguration Model Based on Time Petri-Net and Its Solution Method

The manufacturing system change from hierarchy to parallel structure, from concentration to distribution based on notion of Holonic Manufacturing System. In this paper, the problem of how to demarcate the unit of the manufacturing system, management style of the unit, control structure and the corresponding control method are settled. The model on order settlement in system reconfiguration model based on time Petri-net is put forward, order intelligent operation series is guided by a hybrid particle swarm optimization(HPSO) algorithm with Differential Evolution(DE) algorithm. PSO provides initial solution for DE during the hybrid search process. Such hybrid algorithm can be converted to tradition DE by setting swarm size to one particle. Simulation results show that the proposed model and algorithm are effective to order evaluation and implementation.
