【摘要】 库存管理模型在现实生活中有着广泛的运用,同时它也为管理决策者能有效地确定最佳的订购批量有很大的帮助。由于历史数据的缺乏,需求量在很多情况下往往被主观地确定。不确定情况下的两种不同类型的模糊需求模型被建立,即一种是离散的需求模型,另一种是连续的需求模型;不同的模糊总成本对应不同的订购批量,文中针对两种不同的模糊需求类型运用模糊理论去寻找使得总成本达到最小的最佳订购量。本文中的数学方法能被广泛运用于其它模糊需求的库存模型的建构中。更多还原

【Abstract】 The single-period inventory models have wide applications in the real world in assisting the decision maker to determine the optimal quantity to order. Due to lack of historical data, the demand has to be subjectively determined in many cases. The models for cases of two different fuzzy demand types are constructed; that is, one is the model of discrete demand, the other is the model of continuous demand. Although different fuzzy total cost resulted from different order quantity, in this paper, a fuzzy theory is adopted to find the optimal order quantity in terms of the sum of cost about two different demand types.The methodology of this paper can be applied to construct other inventory models with fuzzy demand.更多还原
