摘 要: 基于模糊数的可信性理论.引入利润率、需求率、库存成本率.根据它们对库存总成本的影响赋予不同的权重得到库存评价指标.据此对产品库存规模进行分类。假定多产品的库存容量为LR型模糊数.根据库存评价指标定义了与单位存储空间相关的额外库存成本.从而确定了最优订货策略。最后通过算例探讨了此模型的有效性和稳定性。 Based on the theory of credit, the paper introduces profit rate, demand rate and inventory-cost rate, puts the different weight to the three rates according to their effects on the inventory total cost in order to get the inventory value index, classifies the items by inventory quantities. The storage capacity of multi-item is supposed to be LR fuzzy number, the paper defines the added inventory costs that are related to unit storage space based on the inventory -value index and gains the optimal order strategy.
