摘要/Abstract

摘要： 针对城市地下燃气管网的管道腐蚀问题确立评价指标体系并结合数理统计与运筹学的有关理论与方法确定指标权数．在多指标综合评价合成技术基础上建立了多因素影响下燃气管网的安全评价模型着重研究了燃气管网安全影响数据的规范化、标准化处理．模型应用还具有自适应性．该模型对316个样本的评价结果与专家评价结果的一致率达87％表明该模型可有效应用于多指标综合评价问题．

Abstract: In view of the erosion of the underground gas conduit network in the cityan evaluation index system of the network security was established．In this systemthe index weights were determined by us ing statistical methods as well as operations research．Based on the technique of mult- i index synthetic evaluationa model of security evaluation for the network under the influence of various factors was establishedand the standard processing method of the data reflecting the network security was investigat-
ed in paticular．The model proposed here possesses a selfe-adaptive function．The evaluation results of 316samples through this model consistented with the experts′results by the ratio of87％it demonstrates that this model is applicable to the problem of synthetic evaluation for mult- i index．

Key words: gas conduit network, security evaluation, mathematical modeling
