Ranking of the Affecting Factors on the Quality of Automotive Mechanical Parts (Engine) via MCDM Approach Using DEMATEL Technique

One of the most serious and practical discussions in most planning and management systems is choosing the right option. Economic, communication, industrial, social systems and Information processing methods, on the one hand, and subtle decision-making conditions, high ambiguities, and environmental complexities, on the other hand, have increased the need for this process, given the intense competition in the automotive industry. Therefore, leveling the factors affecting the quality of car parts for each car manufacturer is a big challenge considering the different goals and criteria that exist for that company. The aim of this research is to level the factors affecting the quality of mechanical parts of the car (engine) with a multi-criteria decision-making approach (MCDM ) using DEMATEL technique for the parts manufacturing company. In this study, using reference books and experts' opinions, the factors affecting the quality of automotive mechanical parts are identified and then using the Delphi method, the screened factors and the most important factors are then selected by DEMATEL method. These factors have been reviewed and finally leveled.
