构建了单供应商两分销商的VMI系统在需求随机情况下补货发货模型，并设计价格补贴机制协调VMI实施后供应商与分销商的利益．假定需求服从正态分布，总成本函数中考虑分段的运输成本函数，带安全库存及服务水平约束，供应商拥有库存的两级供应链．算例结果显示：实施VMI后采用基于共同补货期的时问协调决策模型能够降低供应链总成本，当采用等分法进行利益协调时，在设计的价格系数下，供应商与两分销商均有不同程度的获利．最后参数敏感性分析显示：分销商的缺货成本B的变化对价格系数影响不大，而分销商1的年需求均值u1、供应商处理分销商1每一个订单的固定成本S01和实施VMI前分销商1每次的订单处理成本S1的变化均会对价格系数产生不同程度的影响．

The replenishment policy of VMI with one supplier and two-distributors is studied under stochastic demand and price subsidy mechanism is designed to coordinate the interests of the supplier and distributors after the implementation of VMI. Demand is assumed to obey normal distribution, and the transportation cost function is assumed to be piecewise. The safety stock and service level constraints are also taken into account. Results show that, total supply chain cost is reduced through the use of common replenishment epochs after VMI replenishment. When using equal allocation method in the coordination of interests, the supplier and distributors have different levels of profit improvement with the price factor designed. Finally, parameter sensitivity analysis shows that, the change of distributors＇ stock-out cost B has little effect on the price factor, while the changes of Ul （the average demand of distributor one）, S01 （the supplier＇s fixed processing costs for each order of distributor one） and S1 （per order processing costs of distributor one before VMI） have different degrees of impact on price factor.
