油气管道设计多方案综合评价综述

石油天然气长输管道工程具有高技术、高投入、高风险的特点 ,因此对各工程方案进行科学决策便显得非常重要了。 2 0世纪 90年代以来 ,随着对模糊集合理论 ,灰色系统理论和物元分析的引入 ,形成了一些比较完善的用于油气管道设计方案综合评价的方法。对这些现有方法进行了总结和阐述 ,并针对现有评价体系中所存在的问题提出了一些见解 ,为综合评价理论在油气管道设计中的应用发展理清了思路

Summary on Overall Evaluation of Multiple Options for Oil & Gas Pipeline Design

The long distance oil & gas pipeline projects have such characteristics as high tech,large investments and high risk,so it is very important to make decision scientifically for the schemes.Since the 90's in 20th century,due to application of the fuzzy set theory,gray system and element analysis,a set of relatively complete overall evaluation methods of multiple options has formed gradually,which applies to oil & gas pipeline design.Summarized and expounded are all these existing methods.
