Methods and approaches mapping for supplier selection: Literature review.

Supplier selection is one of the important stages that should be considered in supply chain management. Some researchers have researched the supplier's selection with different methods or approaches. This research aims to map the use of methods or approaches and criteria in the selection of suppliers. Article research was done through relevant journals selected by the selection of suppliers issued from 2013 to 2020. A total of 42 article journals were selected and analyzed. The stages start from the article research related to supplier selection. Then, the articles are identified and classified based on their method or approach. The grouping of supplier selection methods is divided into two namely a single model and an integrated model. The commonly used methods of the selection of suppliers in the single model are AHP, TOPSIS, VIKOR, SAW, and WP. Whereas, the integrated models that are commonly used are Fuzzy AHP, Fuzzy TOPSIS, Fuzzy AHP-TOPSIS, AHP-VIKOR, and Fuzzy-AHP & Fuzzy-TOPSIS. The use of a Decision Support System (DSS) assisting supplier decision making, is widely supported by a unified model group. The results of this research are expected to help researchers and companies choose methods to determine suppliers. [ABSTRACT FROM AUTHOR]
