基于需求和缺货预测改进的补货-服务水平组合策略优化

Optimizing of Service-Replenishment Policies Based on Improved Forecast Accuracy of Demand and Under-Stocking on Cooperation

针对单周期产品、易腐产品、耐腐产品和季节性产品,系统地研究了供销节点之间在成本分担合作模式下的补货和服务水平组合策略优化,对每种典型产品给出了组合策略优化方法。对耐腐和季节性产品提出了基于需求和缺货预测改进的变周期向前改进的补货-服务组合策略,可根据实际缺货损害程度改进缺货成本计算精度,从而提高策略的优化程度和实际操作性。结论表明:对各种典型产品,合作的补货-服务组合策略维持了较高而稳定的最优服务水平和补货量,从而有利于供销双方的协调运作。

Joint strategy of service-replenishment policy based on cooperation and cost sharing between vendor and retailer, is analyzed for typical products as single period, perishable, imperishable and seasonal product. Service-replenishment policy is proposed for each typical product. An improved-forward with changing cycle service-replenishment policy based on improved forecast accuracy of demand and under-stocking is also proposed for imperishable and seasonal product. With increased accuracy of cost of under-stocking accounting, according to the real under-stocking hurt, this policy will also increase both the optimal degree and actual operation. The conclusion is that: joint strategy of service-replenishment policy optimization keeps higher and stable service level, and then, incurs higher and stable replenishment lot size as a result, which will help to har-monize the operation and cooperation of the two parts in reality.
