ANALYSING THE OPERATIONAL RISK INVOLVED IN THE MANUFACTURING OF AUTOMOBILES

Abstract

Risk management is an important issue in manufacturing companies in to‐ day’s competitive market. Failure modes and effects analysis (FMEA) method is a risk management tool to stabilize production and enhance market com‐ punitiveness by using risk priority numbers (RPN). Although the traditional FMEA approach is a successfully and commonly used method, it has some shortcomings such as notion of equal importance of the factors, severity, incident and delectability, and not following the ordered weighted rule. Thus, in order to improve RPN, an added method blending grey personal analysis (GRA) with FMEA is used in this study. The purpose of this paper is to contribute to risk management activities by proposing solutions to assembly line challenges in an automotive manufacturing company by using combined GRA and FMEA method. In the proposed method, the priorities of production failures were determined by GRA method, and these failures were minimized by using FMEA technique. The study results indicated the actions that lead to enhancement in the product. The accomplishment of cor‐ restive/preventive activities resulted in 96 % development in door seal cuts problem caused by the door step building. Door seal cuts problem caused by instrument panel assembly and the noisy door window problem are solved totally
