基于模糊规则的物流中心优选评价模型

为了合理选择物流中心的地址,首先构建了物流中心选址评价指标体系,然后应用Delphi专家评分法通过集成多个专家的意见,得到各指标的相对权重和下层指标满意度区间模糊数;经过分层结合,得到诸方案各上层指标的满意度区间模糊数.综合各上层评价指标得到各方案的最后综合模糊评分.利用区间数排序方法,对所有方案进行排序,从而得到物流中心综合选择的优先顺序,为实际决策提供依据.最后通过一个实例验证了模型的有效性.

An Evaluation Model Based on Fuzzy Rule for Logistics Centers

To locate logistic distribution centers,a location/evaluation index system is built.Then,the fuzzy Delphi method is used to synthesize experts' comments so as to give the relative index weights and fuzzy interval numbers to the satisfaction of the indices at low levels,while the fuzzy interval numbers to the satisfaction of the indices at high levels in different alternatives are given through hierarchical association.Synthesizing all the evaluation indices at high levels,the final overall fuzzy marks are given to all alternatives,and they are ranked with interval numbers.Thus,a priority order is provided for the overall selection of logistics as a reference for actual dicision-making.An example is given to verify the validity of the model proposed.
