An Integrated QFD-TOPSIS Approach for Supplier Selection Under Fuzzy Environment

Abstract

This article describes how supplier selection is a multi-index problem which affects the efficiency of the whole supply chain in both manufacturing and service industries. Considering the importance of selecting effective suppliers, this article aims to integrate two well-known techniques, Quality Function Deployment (QFD) and The Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) in order to evaluate suppliers and rank them based on their merits. In order to handle the inherent uncertainty in the process of experts' judgments, fuzzy logic is involved in the methodology applied in this study. The validity of the utilized integrated approach is demonstrated through conducting a case study in the detergent manufacturing industry in Iran.

Creating a Functional Interdependency Map for Supporting the “Act of Improvement” in Business Process Improvement Projects

“…In case of conditional interdependencies, the output information produced by technique "A" is mandatory for using technique "B" (Bruhn, 2019). For example, one cannot use the QFD (Quality Function Deployment) technique (Akao, 1990;Knorr & Friedrich, 2016;Rahpeyma & Zarei, 2018) without knowing the customer requirements, which have to be provided by other techniques (e.g., "CTQ-Matrix" (Meran et al, 2013)). However, in practice the differentiation between complementary and conditional interdependencies is hard to keep up.…”

Supplier Selection in Family Small and Medium Enterprises

“…They incorporated quality, service, delivery, price, and environmental responsibility as criteria or attributes. A similar approach to fuzzy TOPSIS was utilized by Rahpeyma and Zarei (2018) to evaluate the suppliers of a detergent manufacturing industry. Chang (2019) proposed an intuitionistic fuzzy WAM for a supplier selection problem with missing or nonexistent data.…”
