随机需求下的供应链库存控制策略研究

考虑了由多个供应商、一个配送中心组成的二级供应链系统在市场需求为随机情况下的多品种库存问题。通过确定各变量之间的关系，以配送中心损失期望值最小为目标函数，建立了一个混合整数非线性规划模型；利用求解多元函数条件极值的办法来求解该问题模型；最后给出了一个算例进一步诠释了该解法，从而丰富了在面对市场为随即需求下的多品种库存控制策略的研究工作。

Strategy research on supply chain inventory control under stochastic demand

Taken into account by multiple suppliers,a distribution center consisted of two supply chain system in the market demand for the random case of many species inventory problem.By identifying the relationship between each variable to the smallest expected loss distribution center for the objective function,the creation of a mixed-integer nonlinear programming model,while the use of multi-function solution of conditional extremum approach to solving the problem model,and finally gave the a numerical example to further interpretation of the solution.Thus enriched the market immediately in the face of demand for many varieties of inventory control strategy studies.
