Selection of welding robot by multi-criteria decision-making method

Welding is a method to join parts together by stable connection. used in many different fields. The limitations of manual welding methods are gradually eliminated when using robots. selection robot has great influence on the efficiency process. Choosers (customers) often encounter problems choosing among products that available market. During this study, seven types robots were given make choice including AR700, AR900, AR1440, AR1730, AR2010, MA3120, VA1400 II. These options commonly processes. There variety parameters (criteria) evaluate each these However, value criteria very different. considered best should be based all those criteria. At point, called MCDM (Multi-Criteria Decision-Making). In research, two rank robots: MARCOS (Measurement Alternatives and Ranking according COmpromise Solution) PSI (Preference Selection Index). determination important quantities for been carried out various methods, MEREC (MEthod Removal Effects Criteria), EQUAL, ROC (Rank Order Centroid) RS Sum) methods. was four times corresponding sets weights. Meanwhile, method, we do not need calculate weights All five ranking results indicate same alternative. MA3120 one. reliable enough multi-criteria decision-making required, firstly,
