【摘要】：研究多维组件,单一产品的双需求型面向订单装配(Assemble-to-order,ATO)系统.产品需求为延期交货型,当其不被满足时将产生缺货等待成本;而独立组件需求为销售损失型,其不被满足时将产生缺货损失成本.该问题可以抽象成一个动态马尔科夫决策过程(Markov decision process,MDP),通过对双需求模型求解得到状态依赖型最优策略,即任一组件的最优生产库存策略由系统内其他组件的库存水平决定.研究解决了多需求复杂ATO系统的生产和库存优化控制问题.提出在一定条件下,组件的基础库存值可以等价于最终产品需求的库存配给值.组件的基础库存值与库存配给值随系统内其他组件库存的增加而增加,而产品需求的库存配给值随系统组件库存和产品缺货量的增加而减少.最后通过数值实验分析缺货量及组件库存对最优策略结构的影响,并得到了相应的企业生产实践的管理启示.
[Abstract]:This paper studies multi-dimensional components, a single-product dual-demand oriented assemble-to-order assembly ATO system. The product requirement is delayed delivery. When it is not satisfied, there will be a cost of waiting for the goods out of stock; And the individual component demand is the sales loss type. This problem can be abstracted as a dynamic Markov decision process (MDP). The state-dependent optimal strategy is obtained by solving the dual demand model. That is, the optimal production inventory policy of any component is determined by the inventory level of other components in the system. The production and inventory optimization control problem of multi-demand complex ATO system is studied and solved. The underlying inventory value of the component can be equivalent to the inventory ration value of the final product requirement. The underlying inventory value and the inventory ration value of the component increase with the increase of the inventory of other components in the system. The inventory ration value of product demand decreases with the increase of system component inventory and product shortage. Finally, the effects of stock shortage and component inventory on the optimal policy structure are analyzed through numerical experiments. And has obtained the corresponding enterprise production practice management enlightenment.
