Supply Chain-Supplier Evaluation Using the Fuzzy Swara and Fuzzy Copras Methodologies for Macro and Micro Supplier Companies: Peru Case Study

Abstract

Abstract—The research proposal analyzed five suppliers of explosives for mining, in this case two are macro companies and three are micro companies, with which the application of fuzzy SWARA and fuzzy COPRAS methodologies is evaluated, for the

analysis of supplier selection numerically evaluating decision- making criteria, classification and prioritization of suppliers that

meet the demands and characteristics requested by the mining companies for the choice of suppliers. The fuzzy SWARA fuzzy methodology was used to calculate the fuzzy weightings, and for the fuzzy COPRRAS methodology, decision making matrices were made using benefit and cost criteria. The proposed research concluded that the macroenterprises meet the numerical selection criteria, it also indicates that the first microenterprise can also be a very viable option and the last two microenterprises are discarded according to the selection criteria because they do not meet the evaluation criteria given by the methodologies proposed in the research.
