| 摘 要： | 针对LR型模糊提前期需求问题，建立了连续盘点库存策略中提前期为可控变量且具有服务水平约束的库存模型，并运用可信性测度理论对模型进行反模糊化求解。分析表明：1）通过额外投资对提前期进行压缩时，存在一个合理的压缩范围；2）高的服务水平要求高的库存成本，在设定服务水平时，应综合考虑服务水平与库存成本，选择最优的平衡点。

| Abstract: | Aim at the demand of LR-fuzzy lead time,a continuous review inventory model with variable lead time and service level restriction was established,and the optimal order quantity and lead time were derived by using the theory of credibility measure.Numerical analysis shows(1) a reasonable crashed range is available in the process of compressing lead time at the expense of an additional investment;(2) high service level depends on high inventory cost.When setting the service level,decision-makers should compre... |
