摘要: 为解决传统故障模式和影响分析(FMEA)存在的主观误差、结构转换和逻辑混乱等问题,提出一种基于逻辑结构数的改进型FMEA方法,该方法利用模糊集和层次分析法(AHP)降低主观误差,通过事故树分析(FTA)产生逻辑结构数,利用逻辑结构数实现故障原因向故障模式的转换,并通过逼近理想解排序法(TOPSIS)处理数据,得到各个故障模式的风险优先数,使FMEA具有逻辑性和整体性;将该方法应用在浮式生产储油卸油轮(FPSO)三相分离器的研究上,验证该方法的有效性。结果表明:采用该方法找出的三相分离器的主要故障模式更加准确,更加贴合生产实际,更利于工程人员操作。

Abstract: In order to solve problems of subjective error, structure conversion and logic confusion in traditional FMEA, an improved FMEA analysis method based on logical structure number was proposed. Fuzzy sets and AHP were used to reduce subjective errors, generates logical structure numbers through FTA analysis, logical structure numbers was used to realize conversion of failure causes to failure modes, and data was processed through TOPSIS to obtain risk priority number of each failure mode to make FMEA analysis have logical and integral. Method was applied to research of FPSO three-phase separator to verify effectiveness of method. The results show that main failure mode of three-phase separator found by this method is more accurate, more suitable for production practice, and more conducive to operation of engineering personnel.

Key words: logical structure number, improved failure mode and effect analysis (FMEA), analytic hierarchy process (AHP), technique for order preference by similarity to an ideal solution (TOPSIS), floating production storage and offloading(FPSO)three-phase separator
