Expert opinion-based multi objective optimization: an application in plasma coating technology

Multi-objective optimization is a very important activity which applied in many different fields. When solving this problem, it to determine weights for criteria. If the weight of criteria determined according dry mathematical formulas, opinion researchers will be ruined. On contrary, if subjective researchers, also easy make mistakes. This study applies method determining based on experts' opinions and conditions must strictly satisfied, thereby both above limitations have been remedied. Such known as FUCOM (FUll COonsistency Method). An application example was carried out multi-objective plasma coating process. Plasma modern technology. increasingly used However, value technological parameters ensure quality high-quality products complicated job. In order requirements product, necessary optimal parameters. Four evaluate process include adhesion strength coating, shear tensile porosity coating. The task values three input (including: spray current intensity, powder feed flow, distance) that desired four are simultaneously achieved. After by method, problem has solved. Experiments verify results were conducted, demonstrating correctness methodology. technology (spray 568.69 A, 31.87 g/min, 170.19 mm, respectively
