This paper presents an optimization method for maintenance scheduling in re-entrant production lines using Lagrangian decomposition coordination method. The proposed approach regards maintenances as jobs within limits of starting and finishing time, so that the schedule can realize not only proper maintenance to prevent facility troubles but also high productivity. A case study is presented for a semiconductor manufacturing system, in which it is difficult to find a proper plan because of complex process flow so that the jobs often re-enter into the facilities. The feasibility of the proposal is discussed using computer simulation results; the proposed method can realizes feasible solutions in the problems where the objective function is set to minimizing total tardiness.
