研究原材料价格波动下多级生产-库存系统的控制问题.所有的原材料价格、半成品加工成本、成品的生产成本、库存费用率和产品的需求率都随时间变动,为此,分析了最优采购、加工、生产决策的必要和充分条件,得到了在某些假设条件下的最优生产-库存策略为JIT(Just-in-time)采购、加工、生产策略,或者为在最开始阶段以最大能力进行采购、加工、生产活动的Bang-Bang策略.
Researching the control of multi-level production-inventory system under the fluctuation of raw material prices.All the raw material prices, the processing cost of semi-finished products, the finished product production cost, the inventory cost rate and the product demand rate all fluctuate with time.Therefore, , Processing, production decision-making necessary and sufficient conditions obtained under some assumptions optimal production - inventory strategy for JIT (Just-in-time) procurement, processing, production strategy, or in the beginning to the maximum Ability to conduct purchasing, processing, production activities Bang-Bang strategy.
