供应商选择过程主要包括根据不同的标准对不同的备选供应商进行评价。这个过程可以作为客户需求和技术需求的组合来处理。也可以将客户视为购买供应商技术专长的公司。因此，这种关系可以作为典型的质量功能部署（QFD）的质量模型进行分析。本文开发了一种基于分析网络过程（ANP）、QFD和订单性能相似理想解决方案（TOPSIS）方法的供应商评估方法，以帮助土耳其的一家投资银行作为现实世界的应用。模糊逻辑用于捕捉人们言语评价中的模糊性。在第一阶段，采用模糊ANP方法计算了供应商选择标准和技术要求重要性的矩阵。在质量室中，将技术要求和标准结合起来，评价两者之间的关系。在第二阶段，基于第一阶段得到的加权标准，采用模糊TOPSIS对供应商进行排序。研究结束后对结果进行敏感性分析。
A supplier selection process mainly involves evaluation of different alternative suppliers based on different criteria. This process can be handled as a combination of the customer needs and the technical requirements. Also customers can be considered as the companies to purchase the suppliers’ technical expertise. Hence, this kind of relationship can be analyzed as a house of quality model typical of quality function deployment (QFD). This paper develops a supplier evaluation approach based on the analytic network process (ANP), QFD, and the technique for order performance by similarity to ideal solution (TOPSIS) methods to help an investment bank in Turkey as a real world application. Fuzzy logic is used to capture the vagueness in people’s verbal assessments. In the first phase, matrices used to define the importance of the supplier selection criteria and the technical requirements are calculated with the fuzzy ANP method. The technical requirements and the criteria are combined in the house of quality to evaluate the relationship between them. In the second phase, fuzzy TOPSIS is used to rank the suppliers based on the weighted criteria obtained from the first phase. The study was followed by the sensitivity analysis of the results.
