【摘要】 研究了给水管网突发污染水质监测点选址的方法,分析了覆盖集法存在的缺陷,并针对这些缺陷提出了一个基于覆盖集原理模型的改进方法,即在基于覆盖集法的突发污染水质监测点优化选址模型中引入报警域,同时考虑节点发生污染事件的概率。为了验证改进模型的合理性,将传统覆盖集法和改进的覆盖集法应用于同一个案例管网优化选址分析,结果表明改进的覆盖集法求得的选址方案更合理。更多还原

【Abstract】 The method for detecting accidental contaminations in municipal water networks was investigated. To overcome a flaw identified in the covering set method,a modification was proposed in this paper. Alarm collection,which was a new concept,was introduced into this model. Meanwhile,probability of accidental contaminations occurring at each node was considered. In order to verify the mode’s rationality,former covering set based methods were used to solve an example,to compare with the results of the modified covering set based method. As a result,the modified covering set based method was more reasonable.更多还原
