摘要: 为提高并联系统生产过程的连续性,提出了考虑缓冲区库存分配的并联系统(3M1B)预防维护模型。首先,考虑并联系统每台设备的故障率与维护率,在并联系统中上下游设备之间建立缓冲区,构建3M1B系统。其次,考虑设备不完美生产的可能性,以缓冲区库存量与设备运行周期为决策变量,以设备最小生产成本率为目标函数建立预防维护模型,求解最佳的预防维护策略与缓冲区库存分配策略。针对此维护模型,采用离散迭代算法与遗传算法进行求解,并比较了2种算法的优劣,结果表明,对于此模型,离散迭代算法优于遗传算法。最后,通过算例验证模型的可行性和有效性。

Abstract: To improve the continuity of parallel production process, a parallel system preventive maintenance model (3M1B) considering buffer stocks allocation is proposed. The possibility of imperfect production of the equipment is considered, that is, when the equipment becomes incomplete, there is a certain probability to produce defective products. The strategy of optimal preventive maintenance and the buffer stocks allocation are devised by establishing the preventive maintenance model with the minimum production cost rate as the objective function and taking the buffer stocks and equipment operation cycle as the decision variables. For this maintenance model, the discrete iteration algorithm and genetic algorithm are used to solve the problem, and the advantages and disadvantages of the two algorithms are compared. The results show that the discrete iteration algorithm is better than the genetic algorithm for this model. At the end, the feasibility and effectiveness of the model are verified by a numerical example.

Key words: parallel system, buffer stocks, preventive maintenance, imperfect production, minimum cost rate
