摘要
通过构建库存优化模型，提出一个基于供应商资金短缺前提下采购两种原材料的最优采购策略。首先利用库存水平和初始资金联合决策求解模型，得到在某一特定库存水平之内只需采购易腐原材料，在该库存水平之外需采购两种原材料的采购策略，且两种情况均考虑资金约束情形。然后在拓展中将单周期库存融资决策延伸到多周期动态库存决策。最后运用控制变量法解决决策过程中涉及到的各种成本参数和采购策略的关系。通过算例验证模型和结论的合理性。
By constructing the inventory optimization model, an optimal procurement strategy of purchasing two kinds of raw materials based on the shortage of suppliersf funds was propose＆ First,the joint decision-making model of inventory level and initial capital was used to get the procurement strategy of purchasing only two kinds of raw materials out of the stock level and purchasing the perishable raw materials within a certain inventory level, both taking the capital constraints into consideration. Second, the single-period inventory financing decision was generalized to multi-period dynamic inventory decision. Third, control variable method was used to {igure out the relationship between cost parameters and procurement strategy in the decision-making process. Finally, the rationality of the model and conclusions was verified through case analysis.
