摘　　要：长输管线设计方案的优选是根据工程设计原则 ,从所提供的预选方案中 ,遴选出最佳设计方案。由于方案涉及到的设计参数和技术经济指标具有典型的层次特征 ,因而可以用层次分析方法来定量确定各种指标相对目标层的权重 ,结合密切值法对各个方案与理想方案逼近程度的计算 ,实现方案优劣排序。实例计算结果表明 ,在天然气长输管线设计方案优选指标体系及结构模型之中 ,AHP -MCZ能从多因素、定量与定性相结合的角度来确定出最优设计方案。为设计者选择技术上可行。Based on the laws of engineering design,the optimum long-distance gas pipeline design plan is selected among many preliminary design plans.The design parameters and economic indexes of design plans are characterized by typical hierarchic properties.These properties can be used as important quantitative index(weight)corresponding to the design object,in combination with MCZ method,which can calculate the approaching extent by comparing preliminary plans with optimal one,the order of prior selected of multiple plans can be determined.The analysis shows that the optimum plan can be defermine by using AHP-MCZ to establish index system and structure model for optimizing the design plans.AHP-MCZ method is effective for designers to select a technically feasible and economically reasonable design plan.
