【Abstract】 To ensure the throughput and improve the system reliability, a model for decision-making of preventive maintenance for series systems with buffers is presented. First, by analyzing the relationship between reliability of each execution unit of production line and operating parameters, a maintenance model considering the operating parameters of execution unit and buffer is established. On this basis, integrating the characteristics of series production lines, a multi-objective optimization model considering maintenance cost, effective operating speed and buffer capacity is established. Finally, a heuristic algorithm is constructed to solve the objective function, and the simulation of a serial packaging production line is carried out, and the results show that the presented model is effective and practical.更多还原
