模糊逻辑法在医疗器械供应商选择中的应用

The Research on Fuzzy Logic Approach for Medical Device Supplier Selection

医疗器械采购流程管理中最关键的步骤之一是供应商选择,它是一种以多准则为特征的决策制定活动。现提出基于模糊逻辑的模型来建立一种合格的医疗器械供应商名录,只有在这个名录中的供应商成员才允许参加投标活动。该模型使用3个主标准和20个子标准,并收集5家供应商数据来验证该模型的适用性。与专家评判法相比,结果显示所提出的模型在建立最合适的医疗器械供应商选择名录时的稳健性,平均误差为(3.83±3.19)。

One of the most critical activities in the management of medical device purchasing process is supplier selection which is a decision making activity characterized by being a multi-criteria based activity.This paper proposed a fuzzy logic system to create a listing of the most suitable suppliers.Only the members of this listing would be allowed to request for offers in a tender.The proposed system used three main criteria and twenty sub-criteria.Dataset collected from five different companies is used to validate the system against experts’opinions.Results show the robustness of the proposed system in creating a listing for the most suitable medical suppliers with an average error of(3.83±3.19).
