外协生产能力不确定下生产控制指标的研究
|
摘要
研究了在外协生产能力不确定和阈值控制机制下,外协在制品的库存和运输在制品到外协企业的时间,对在制品的平均库存成本及外协系统能力平均损失率的影响。建立了平均库存成本及外协系统能力平均损失率指标模型.采用系统仿真法得出了系统的平均库存成本和外协系统能力平均损失率随阈值点改变和运输时间延迟的变化规律.
This paper studies the influence of the WIP inventory that needs for outsourcing,and the transportation time transporting the WIP to outsourcing enterprise have an average inventory cost and outsourcing enterprise capability loss rate under outsourcing enterprise production capacity uncertainty and threshold control mechanism,so average inventory cost and outsourcing system average capability loss rate index model are established and finally adopting system simulation method to find the rule of inventory cost and outsourcing capacity loss with threshold point and transportation time delay changing to assist the company in choosing proper outsourcing enterprise and optimal threshold control points.
