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 andInformation 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 abig 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 (MCDM1) using DEMATEL2 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. The results indicate that among the 14 effective factors identified in the quality of automotive mechanical parts (automotive engine), in terms of leveling these effective factors using DEMATEL technique, 5 factors in order: Repair and maintenance of production equipment, increase Quality standards, Upgrading and updating production line machines, suitable and standard fuel for the engine and the use of spark plugs, timing belts and suitable alternators have had a higher rank than other effective factors.
