A new multicriteria decision support tool based on Fuzzy SWARA and TOPSIS

The problem of selecting 3PL (Third Party Logistics) suppliers is a major issue in the management supply chain and improvement production manufacturing company. A supplier can be defined as company that provides contract logistics services to manufacturer, or main user product service. It called third party because provider does not own products but participates between manufacturer given product. In actual cases, several decision-makers intervene selection each one has his points view wishes take into account criteria which are generally same for all decision-makers. Furthermore, have different weights. this study, we propose method solve problem. consists combination fuzzy Stepwise Weight Assessment Ratio Analysis (SWARA) with Technique Order Preference by Similarity Ideal Solution (TOPSIS). objective optimize decision-making process another, more dynamic model satisfy needs decision-maker. Fuzzy SWARA new methods being used ranking evaluation based on decision makers’ expected degree importance determine weights (Selçuk, 2019). This facilitate estimation preferences regarding meaning attributes weight determination process. TOPSIS multi-criteria identifying solutions from finite set alternatives (Behzadian et al., 2012). To best our knowledge, been developed literature, especially third-party logistic problems. proposed will implemented selling steel products. Keywords: multicriteria support, suppliers, SWARA,
