Abstract：To solve the assembly problem of the aircraft engine with uncertain rework, an optimization model of rescheduling and teams self-reconfiguration of knowledgeable manufacturing system (KMS) oriented to aircraft engines assembly line is build, and an integrated optimization algorithm of both is proposed. In the scheduling phase, dominance relations of operations aiming at optimizing weighted completion cost are derived and applied to generating an initial oper-ation sequence. Three neighborhood structures are defined. A variable neighborhood search (VNS) is used to optimize the the assignment and the schedule of operations on parallel assembly teams. In the self-reconfiguration phase, the configura-tion of the assembly teams is generated according to the assembly line workload balancing without violating the assembly skills constraints, and then optimized by a tabu search (TS). The simulation experiments validate the effectiveness of the proposed model and algorithm.
