基于改进的粗糙集理论和层次分析法的医疗设备供应商选择

Selection of Medical Equipment Suppliers based on Improved Rough Set Theory and Analytic Hierarchy Process

本文针对医疗设备供应商的选择问题,首先构建影响医疗设备供应商选择的评价指标体系,利用改进的粗糙集理论对影响供应商选择的属性指标进行约简,得到客观权重,然后结合约简后核心指标,利用层次分析法得到主观权重。将主客观权重有机地进行组合,对备选供应商做出更科学的评价,该方法能帮助医院做出合理的决策。

In view of the selection of medical equipment suppliers, the evaluation index system of medical equipment supplier selection was constructed in this paper. The improved rough set theory was used to reduce the attributes of supplier selection, and the objective weight was obtained. Then, the subjective weight was obtained by using the analytic hierarchy process. The organic combination of subjective and objective weight made it more scientific to evaluate the alternative supplier. This method could help more hospitals to make a reasonable decision.
