随机需求环境下网状供应链运作中多级库存控制问题研究

摘要

针对供应链库存控制问题研究的重要性和不足,从供应链运作的实际环境出发,假设客户需求和订货前置时间随机变化,并在此条件下研究了网状供应链运作中多级库存控制问题.在给出了网状供应链结构的基础上,重点研究了网状供应链多级库存控制中的费用函数关系,从订货费用、仓储费用和运输费用三个方面研究了供应链节点企业的库存总费用,并将多级库存控制问题转化为为节点企业寻找和求解最优订货临界点和最优订货批量的问题,基于此构建了供应链多级库存控制模型并对该模型有效性的检验提出了相应的方法.%In this paper, in view of the importance and jarring shortfall of the study on supply chain inventory control, starting from the practical environment of supply chain operation and assuming that customer demand and ordering lead time would change stochastically with time, we studied the multi-echelon inventory control problem in the operation of the netted supply chain, then by presenting the structure of the netted supply chain, focused on the cost function relationship in the multi-echelon inventory control of the netted supply chain and the total inventory cost of the supply chain nodal enterprises from the aspects of ordering cost, warehousing cost and transportation cost, and at the end, converted the multi-echelon inventory control problem into the optimal critical ordering point problem and the optimal ordering quantity problem of the nodal enterprises, on which basis, we built the supply chain multi-echelon inventory control model and verified its effectiveness.
