Implementation of Weighted Product Method as Fuzzy Multi-Criteria Decision Analysis (FMADM) in Vendor Selection

A company’s procurement activities are critical because it supports the supply chain process, which allows the company to compete, and because the procurement process will involve many interests from various parties. One of the processes used by companies to procure goods and services is the selection of shipping service vendors. The research objective is to facilitate decision-making on issues related to vendor selection decision-making. Because many parties are decision-makers with different preferences, selecting an expedition service vendor will be challenging. In this study, data processing uses the Weighted Product method with the concept of multiplication to connect the attribute ratings that must be raised first with the relevant weights to determine which courier service vendor provider offers the best. The criteria used in the research on the selection of expedition service vendors are generally considered: the price of service quality, document legality, delivery time, and response time. Based on the weight of each attribute, the most significant value will be selected as the best alternative. The results showed that Alternative 3 (Si Cepat) had the highest score (0.3252), ranked first, and made it the best choice.
