摘要
提出了对天然气长输管道进行故障树模糊分析的必要性和重要性 ,介绍了故障树模糊分析采用的模糊算子计算方法。在天然气长输管道可靠性故障树分析中 ,在考虑实际工程模糊信息的前提下 ,进行了可靠性故障树模糊分析 ,计算出了管道系统的模糊失效概率 ,计算结果更符合工程实际。
In this paper, the problem of optimal selection of natural gas pipeline systems design is studied.Natural gas pipeline systems design is very complex. It is associated a lot of fuzzy factors. According to the actual information of the project, the effect factors of the optimal selection of natural gas pipeline are regarded as fuzzy variables, such as diameter, pressure, compress ratio, compression station's number and expenses etc. with different weights. The judging indexes are obtained through fuzzy relationship operation. Consequently the optimal selection of natural gas pipeline systems design is obtained. The fuzzy decision method can be taken as a theoretical base and the new design method can be used in the engineering design.
