Failure mode and effects analysis (FMEA) with weighting (FAHP) and its comparison with WASPA in the storage of Chabahar oil company

In the area of manufacturing and service activities, the issues like competition intensity, rising expectations, changing demands and increasing development of technology, result the companies obligation in the field of troubleshooting in a safe and healthy environment and elimination of any deficiencies and deviation in the workplace and its performance. Otherwise, it causes the employees and customers dissatisfaction. To achieve this goal, today’s organizations can use a device named FMEA to remove or decreasing potential modes of deficiencies before occurring the accidents and deficiencies. Using this device the companies and organizations assure have provided a healthy and safe environment for workers in order to the workers attempt for the goal of mentioned organization. Using this efficient device can identify and prioritize the potential deficiency modes in the system, procedure product and service, and define and determine the decrease level of potential deficiency modes and finally, to register the result of completed analysis with the goal of preparing a complete reference to solve the future problems. In this study, the verbal variables are used, that later by triangular fuzzy numbers, to fuzzy numbers were applied in order to evaluate ranks and weights of risk factors. To determine each of risk factors through the method of FAHP and ranking and selecting the most important modes of deficiencies the method of WASPAS was used. The proposed model applied to evaluate and rank the potential deficiencies modes in detecting the most important factor of potential risks in the storage of Chabahar oil company
