【摘要】 在经典EPQ模型基础上,考虑周期性不完全预防性维修策略下,以单位产品总成本最小化为目标,构建最优经济生产批量的决策模型.在产品生产总成本模型的构建中,结合设备故障率及次品率随时间增加这一实际问题,引入役龄回退因子和等效役龄概念进行动态预防性维修成本、故障维修成本及次品修复成本的构建.考虑目标函数的复杂性,本文采用粒子群算法对模型进行数值求解,并验证其合理性.更多还原

【Abstract】 Based on the classical EPQ model, considering the periodic imperfect preventive maintenance strategy, construct the optimal decision model of economic production quantity with the goal to minimize the total cost per unit of product. In the production total cost model, considering the practical problem that the equipment failure rate and defective rate increased with time, the age reduction factor and equivalent service age concept are introduced to construct the dynamic preventive maintenance cost, fault recover costs and defective repair cost. Considering the complexity of the objective function, this paper uses PSO algorithm to solve the model, and verify its rationality.更多还原
