Failure modes and effects analysis (FMEA) for the security of the supply chain system of the gas station in China

With the popularity of automobiles, gas stations carry more gas supply and security risks. In order to effectively analyze the security of the supply chain system of the gas station, this study set the gas station as the center, then the upstream suppliers and downstream consumers were classified into three sub-systems, and the whole system was analyzed by using the method of failure modes and effects analysis (FMEA). A total of 50 typical cases of accidents at gas stations in China in the past 20 years have been collected from different websites, uses entropy weight method to deal with the cause of system failure modes, obtains and sorts the risk priority number (RPN). The type and failure cause of the most frequent accidents is the static electricity-induced explosion, and the effective measures to alleviate and deal with the accidents are put forward. The results of the study will help management and gas station staffs reasonably prevent gas station safety risks.
