| 摘 要： | 在总结已有的用于输气管多方案综合评价方法的基础上,构建了一个完整的输气管道设计方案综合评价系统,其步骤是,结合层次分析法(AHP)的研究成果,解决了模糊综合评价中工艺参数和经济指标的权重取值问题,完善了模糊综合评价法;采用效用函数法和密切值法对输气管设计方案集进行综合评价,引入最大兼容度概念对评价方法再进行综合评判,采用最大兼容度模型得到兼容多种评价方法的排序结果,以此作为最终的输气管设计方案优选结果.算例分析表明,该系统能够优选出既满足工艺要求,又经济合理的输气管最佳方案,具有一定的实用价值.

| Abstract: | The projects of gas pipeline have characteristics of high-tech, large investments and high risk, so it is very important to make decision scientifically for the schemes. In this article,based on the summarization of the methods used for the decision-making of the gas pipeline's engineering schemes, a complete optimum system for the gas pipeline's engineering schemes' multi-valuation is created: the values of the weight for the techniques parameters and the economy parameters involved in the fuzzy multi-valuation method are worked out by means of the Analytic Hierarchy Process at first. And then two new multi-valuation methods of efficacy function and TOPSIS (the technique for order preference by similarity to ideal solution) , which are simple and convenient, are used to make decision of the gas pipeline engineering schemes. At last the concept of the maximum compatibility degree is introduced to evaluate the multi valuation methods all above and the maximum compatibility degree mathematical models are used to integrate all the results of methods. The result of the maximum compatibility degree mathematical models would be the final optimum compositor result of the gas pipeline engineering schemes. The calculation shows that the method can optimally seek out the best scheme, which not only satisfies the technological requirements,but also is economical and reasonable. |
