基于客观信息熵的冶金备件供应商选择方法

How to Select Metallurgy Equipment Suppliers Based on Impersonal Message Entropy

设备质量是影响冶金企业生产及其运作的关键因素,供应商选择又直接关系到所采购的设备质量。本文应用模糊聚类技术和粗糙集理论,将大量数据进行模糊聚类,在信息熵知识的基础上确定了各个评价准则的权重分配,从而综合评价供应商,为供应商的选择提供了理论依据。

The quality of Equipment which is affected by the selection of supplier is the key factor of the production and operation in Metallurgy field. The amount of data is aggregated by using fuzzy aggregation theory. The weight of every factor is put out impersonally by using the knowledge of message entropy in rough set theory. The method evaluated suppliers synthetically, and gives the mathematic basis for the suppliers selection.
