摘要：在论述了自２０世纪９０年代以来国内外天然气管网优化设计方法的基础上，讨论了几种常用的优化方法，并分析了这些方法的优缺点。针对传统优化方法收敛速度慢、易于陷入局部最优解等缺点，提出将近几年来新兴的智能优化算法应用到管网优化设计问题中，将多种方法有机结合，提高算法的性能。

Abstract： Based on an analysis of the optimal design of natural gas pipeline networks made by many researchers in the world， this paper discussed some frequently used optimal design methods and analyzed the advantage and disadvantage of these methods． To the disadvantage of traditional optimal methods that converge slowly and whose results are not global， and in order to improve the efficiency of algorithm，it brought forward some new intelligence optimization methods that can be applied in natural gas pipeline networks-optimal designs by integrating many methods．
