Abstract: Based on the analysis of the differences and similarities between the scheduling problem of 4S autodealership maintenance service system and the manufacturing system,the form erresearches designing the former scheduling problem with the goal of minimized customers waiting time and describing it as a dynamic FJSP problem exists obvious bottleneck.Then this paper decompose and simplify the problem by the theory of constraints,set the buffer and build the buffer management mechanism to realize the scheduling schemes coordination between the bottleneck and non bottleneck resources.The rescheduling strategy is designed with the consideration of bottleneck and non bottleneck resources characteristic and the dynamic scheduling is achieved.Finally,the example verifies the algorithms feasibility and effectiveness.
