摘要
针对2M1B生产系统由于发生故障将造成生产停滞,增加短缺成本的问题,构建了多情景模式下考虑产品次品率的预防维护模型.分析缓冲区库存变化的轨迹,确定不同的缓冲区库存情景模式,构建生产周期内不同情景下缓冲区库存持有成本模型.以预防性维护时的次品率阈值水平,建立缓冲区库存时次品率的阈值水平和缓冲区库存量大小为决策变量,以生产周期内单位时间总费用最小作为目标建立生产系统预防维护模型,总费用包括预防性维护费用、库存持有费用、返工费用、短缺费用以及保修维修费用.运用离散迭代算法对模型进行优化求解,通过数值算例验证了所提出模型的适用性与有效性.
This paper proposes a preventive maintenance model under multi-scenario modes to solve the problem of production stagnation and shortage cost caused by the failure of 2M1B production system.This paper analyzes the buffer inventory change track,determines different scenario mode,and develops the buffer inventory holding cost models under different scenarios in the production cycle.Considering the rate threshold level of defective rates during preventive maintenance,a preventive maintenance model with the threshold level of defective rates when establishing the buffer inventory and the size of the buffer inventory as decision variables,and with the minimum total cost per unit time in the production cycle as the objective,is presented.The total cost includes preventive maintenance cost,inventory holding cost,rework cost,shortage cost and warranty maintenance cost.The discrete iterative algorithm is used to solve the model,and a numerical example illustrates the practicality and effectiveness of the proposed model.
