| 摘 要： | 时变需求库存模型的基本假设是由所处的经济环境是确定的,但是现实环境通常是不确定的;文章放松这一假定,将随时间递增的需求函数改写为模糊递增需求函数,研究单周期模糊递增时变需求库存问题,并建立相应的数学模型;利用一种模糊数的排序法寻求最优订购量,并给出应用实例。

| Abstract: | The basic assumption of the inventory model with the time-varying demand is that the economic environment is deterministic.However,the real environment is often uncertain.On the basis of relaxing the assumption, the increasing time-varying demand function is replaced by the fuzzy one.The single-period fuzzy inventory problem is discussed in consideration of the fuzzy increasing time-varying demand and the mathematic model is established.A method for ranking fuzzy numbers is applied to finding the optimal order quantity and the corresponding numerical examples are also given. |
