| 摘 要： | 库存管理模型在现实生活中有着广泛的运用,它为管理决策者有效地确定最佳订购批量提供帮助.然而,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,因而带有一定的模糊性.本文针对两种不同类型的模糊需求:离散型与连续型,运用模糊理论分别建立了相应的模糊库存模型.该模型不同于已有的模糊库存模型如下:在现有的模糊库存的文献中,大多采用的是利用模糊集的知识对确定EOQ模型加以研究,而本文从模糊理论的角度对报童问题进行研究.

| Abstract: | The inventory management models have wide applications in the real world in assisting the decision maker to determine the optimal order quantity.Due to lack of historical data,the demand has to be subjectively determined in many cases.Two different fuzzy demand models are constructed;that is,one is the model of discrete demand,the other is the model of continuous demand.In this paper,the fuzzy theory is adopted to construct the fuzzy inventory models respectively.The models developed by this paper differ from the existing models related to fuzy demand at the aspect below.The existing fuzzy inventory papers usually add the knowledge of fuzzy set into the classic deterministic EOQ model,but this paper considers the Newsboy problem. |
