摘要
根据物流中心选址方案评价问题的特点,在考虑物流系统管理的动态性和物流选址方案评价指标信息的模糊性特征的基础上,提出了一种基于模糊物元可拓的物流中心选址方案优度评价方法。在构造评价模型时,将三角模糊数引入物元特征量值,提出了一种运用三角模糊数表示物元特征量值的模糊物元,使其可以方便合理地对不确定性的模糊性指标信息和确定性的精确指标信息进行描述,从而具有更广的适用面。最后通过算例对该方法进行了验证。结果表明:该方法合理、有效,且相对其他方法具有一定的优越性。
According to the characters of the logistics center location project evaluation,considering the dynamic character of the logistics system management and the fuzzy of the evaluation index information of the logistics center location projects,authors put forward method of priority-degree evaluation of logistics center location projects based on the extensional fuzzy matter-element.At the course of constructing the evaluation model,authors leaded the triangular fuzzy numbers into the value of the matter-element characteristic variables,and offered a kind of fuzzy matter-element which used the triangular fuzzy numbers to describe value of characteristic variables.This kind of fuzzy matter-element can conveniently and reasonably describe both the uncertain fuzzy index information and the certain accurate index information.Thus,it has a broader applicable scope.Finally,the method was verified by an numerical example.Results show that the method is reasonable and effective.Compared with other methods,it has better superiority.
