Abstract:
A Petri net with controller is used to model discrete events in flexible job shop scheduling problem (JSSP). It not only has the modeling capability of a traditional Petri net, but also it can depict system characteristics, such as equipment maintenance, different types of priorities, and so on. It is flexible in responding to unexpected scenario changes and is thus robust to system disturbances. The JSSP is characterized by flexible routings, and flexible machines and labors; and the scheduling results are obtained based on genetic algorithm and simulated annealing algorithm(GASA). Themethod is developed to address the dynamic scheduling problem in manufacturing systems constrained by machines and labors. After using crossover, mutation, probabilistic updating strategy and re-assignment strategy and so on genetic and simulated operation a best or second best scheduling plan can be found. Simulation results based on job shop scheduling show that the method is feasible and efficient.Received on January 13, 2006References: 13
