Research on scheduling problem in lean production for crane service system based on queue theory

A simulation system is designed and realized under the guidance of lean production principles and methods.The article advances new scheduling methods with a considerate priority rule.The new scheduling methods considers the affects of the latency time of all the work areas,the moving distance of the crane and the crane’s service time for the different work area’s request.A simulation study is performed to compare the new job shop scheduling problem in lean production with traditional scheduling methods and the simulation result shows that the designed new scheduling method is superior to the traditional ones evidently.
