In the process of building up the system, all the following works are done: confirming the index system of the gas pipeline by the maximum quadratic mean deviation analysis, caculating the index weight by the means of AHP, bringing forward three easy and useful methods (TOPSIS, the effect function and the integration index) of the gas pipeline's engineering schemes' multi-valuation and at last the mathematical models of the maximum compatibility degree is introduced to integrate all the results of all methods above.

在构建这个系统的过程中，主要从事了以下一些工作：通过统计理论中的最小均方差法分析确立了输气管道指标体系；采用层次分析法对输气管道指标权重进行了分析计算；提出三种简单易行的用于天然气管道设计方案评价的新方法：理想点法、效用函数法和综合指数法；最后将决策理论中的最大兼容度模型用于输气管设计方案评价中。
