Extruder line selection with fuzzy CRITIC and fuzzy MAIRCA for a cable company

Abstract

The cable industry carries out production with high raw material costs. Extruder lines make a difference in terms of product quality and costs. Therefore, the selection of the best line is important. In this study, four extruder lines were considered for a cable company for the production of a new insulation material. A total of seven evaluation criteria were determined for all alternatives. The decision-making group, consisting of production managers of the company, evaluated all alternatives under the criteria using linguistic expressions defined in Pythagorean fuzzy and triangular fuzzy number sets. As a result of the evaluations, objective criterion weights were determined using the Fuzzy CRITIC method with Pythagorean fuzzy numbers, and then the extruder line selection was carried out using the Fuzzy MAIRCA method with triangular fuzzy numbers. Sensitivity analyses were conducted to measure the impact of criteria on the obtained results. In the step of weighting the criteria, the energy usage criterion stood out. It was determined that the Bobin line is the most suitable for the conversion of the HFFR product into the final product. The study identified the priority line for the company where the application was carried out.
