ENHANCING HANDHELD POLISHING MACHINE SELECTION: AN INTEGRATED APPROACH OF MARCOS METHODS AND WEIGHT DETERMINATION TECHNIQUES

Abstract

The handheld polishing machine plays a pivotal role in enhancing the aesthetics of household products, making it a vital device. This research aims to identify the optimal option among the available types. Thirteen diverse handheld polishing machines were utilized for evaluation. Six key criteria were carefully chosen to assess each alternative, encompassing price, capacity, polishing disc diameter, polishing disc speed at idle, machine weight, and supplier warranty period. The relative importance of these criteria was determined using four distinct methods: Equal weighting, RS (Rank Sum) weighting, ROC (Rank Order Centroid) weighting, and Entropy weighting. The MARCOS (Measurement Alternatives and Ranking according to COmpromise Solution) method was employed to rank the alternatives. Remarkably, all four different weighting methods consistently led to the same conclusion, identifying the best and worst options.
