摘要
针对钢铁物流加工配送中心选址的评价问题,提出一种融合粗糙集和熵权法优势的评价方法,利用粗糙集的等价关系对评价指标体系进行了约简,通过熵权法计算各指标的权重,求出各备选点的评价值并进行优劣顺序的排序,筛选出符合决策者期望的最终决策节点。结果表明:所提出的方法在选址评价过程中具有操作简单的特点且更加客观合理,能够为钢铁物流加工配送中心选址提供借鉴。
For site selection and evaluation of steel logistics processing and distribution center, a kind of evaluation method was put forward, which combines rough set with entropy weight method to objectively and reasonably evaluate logistics capability of alternative points in processing and distribution centers. The equivalence relation of rough set was used to reduce the evaluation index system, and the weight of each index through the entropy weight method was calculated. The evaluation value of each alternative point was figured out and ranked in order of merits and demerits, and the final decision node that meets the expectation of the decision maker was selected. The results show that the proposed method has the characteristics of simple operation and it is more objective and reasonable in site selection evaluation, which can provide reference for the site selection of steel logistics processing and distribution center.
