Abstract: Traditional workshop scheduling problems assume that machines are always ready to be used. It is ignored that machines are needed to be maintained. There is a complex coupling relationship between maintenance plan and production scheduling. In order to minimize maintenance costs and improve production efficiency, it is needed to integrated optimize preventive maintenance and production scheduling. As operation hours of machines are essence for preventive maintenance, an integrated optimization model of preventive maintenance and flexible job shop group scheduling is proposed aiming at minimizing total completion time of the last operation of each machine and total costs. In order to improve local search abilities, an improved artificial bee colony(ABC-AN) algorithm based on an adaptive variable neighborhood search mechanism is proposed. Test cases from literatures and three different size practical cases are used to verify the proposed and algorithm. The proposed integrated optimization model is validated by comparing results of integrated optimization and that of separated optimization.
