Evaluating applicability of VIKOR method of multi-criteria decision making for parameters selection problem in rotor spinning

Optimum spinning machine parameters selection among available alternatives with different significances is a difficult task in textile industry. To overcome disadvantages associated with statistical methods that are used in such kind of problems, multi-criteria decision making approaches (MCDM) were employed by researchers. TOPSIS, AHP-TOPSIS and ELECTRE are three popular techniques in spinning problems. VIKOR, the Serbian name; Vlse Kriterijumska Optimizacija I Kompromisno Resenje, means multi-criteria optimization and compromise solution is a novel approach that has priority over other MCDM methods in terms of precision in final ranking. In this study, selecting the appropriate doffing tube components and its adjustment for 30Ne rotor spun yarn that is intended to be used for weft-knitted fabric will be provided by this approach. Yarn samples were spun considering three variables namely, the distance between the nozzle and rotor, the extractive nozzle and the draw-off tube. Feasible alternatives were ranked on the basis of the yarn quality parameters by the VIKOR and the best alternative for increasing weft-knitting machine efficiency was introduced. According to the final ranking, the spinning condition in which the sample was spun using a spiral nozzle, a doffing tube without a torque stop and a closer setting had the highest performance.
