考虑到易变质商品在一个销售周期内会有一定数量的商品发生变质,构建了一个考虑在一个销售周期内所产生的变质数量可折价回购以及库存水平影响需求的易变质品的库存模型,而且针对销售周期内的缺货数量,模型假定采取部分延迟订购的策略。针对这一模型,给出了平均利润函数并证明了其存在最优解,然后通过算例完成了不同销售价格、不同折价回购比例和不同库存影响因子条件下的最优订货策略的确定以及其余相关参数的灵敏度分析,分析结果可对零售商的订货策略有一定的参考价值.
Considering that a certain quantity of commodities will deteriorate in a sales cycle, a stock model of deteriorating products considering the deterioration of the quantity of metamorphic refunds generated in a sales cycle and the impact of the inventory level on demand will be constructed. And for the out-of-stock quantity during the sales cycle, the model assumes a partially delayed strategy. According to this model, the average profit function is given and its optimal solution is proved. Then, the optimal ordering strategy under different selling prices, different discount repurchase ratios, and different stock influencing factors is determined through an example. The rest of the sensitivity analysis of the relevant parameters, the analysis of the retailer’s ordering strategy can have some reference value.
