Integrating fuzzy AHP and Z-TOPSIS for supplier selection in an automotive manufacturing company

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Selecting the right supplier is one important process in a supply chain of a company. It will reduce procurement cost but increase stakeholders’ satisfaction. Living in the environment filled with uncertainties, while the suppliers are prescribed under multiple criteria and also the expert may not be able to evaluate the suppliers precisely, fuzzy multi-criteria decision making (MCDM) is used to handle this uncertain situation. However, the classical fuzzy MCDM assumes decision information is completely reliable. Thus, the main aim of this study is to incorporate the degree of reliability of the expert’s judgment in fuzzy environment by integrating fuzzy MCDM with Z-number. Fuzzy AHP is used to determine the weight of criteria/sub-criteria and rating the suppliers in an automotive manufacturing company, while Z-TOPSIS is used to evaluate the overall performance of suppliers. Results of the evaluation would help the purchasing manager to determine the right supplier that fulfills the company’s goal. Besides, the methodology of this study is a good guide to be implemented in other multi-criteria decision making problems.
