摘要: 本文运用多目标灰色局势决策方法,针对油气管路设计,取管材为事件,设计方法为对策,以管材和设备投资、年折合费用、管内摩阻、管路使用年限和管道结构可靠度为决策目标,就油气管线选用动力设备、管材及设计方法,进行了决策分析,给出了决策模型。并结合实例进行了计算,在动力设备已定,仅两种可供选用的管材(16Mn钢和中碳纤维复合材料)时,其决策结果为:应选用16Mn钢管材,且采用可靠性灰色优化设计方法为宜。就油气管路设计方法而言,常规设计、一般优化设计、可靠性设计和可靠性灰色优化设计,后者与前三者比,后者更优越、更合理。

Abstract: The multi-objective grey situational decisison method is applied to the design of oil orgas pipeline,By treating pipe material as event and design method as countermeasure,andtaking the cost of piping material and installation,the yearly converted expenses on pipeline,pipe resistance,service life of pipeline,and reliability of pipeline as decision ohectives,wemade a decision analysis on pipeline power installation,pipe material and design methods ofoil and gas pipeline,and gave a decision model in this paper.The calculation of a real example shows that 16Mn steel and the reliability grey optimum design method are an optimumdecision,if power installation is known;and there is only two options of 16Mn steel and carbon fiber composite. As far as the methods of reliability design and reiability grey optimumdesign are concerned,the grey optimum design is better.

Key words: gas pipeline, grey system, situation decision, reliability design
