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。 This paper studies the method of site selection of water quality monitoring point in water supply network and analyzes the defects of cover set method. In view of these defects, an improved method based on cover set principle model is proposed, that is, burst based on cover set method Pollution of water quality monitoring sites to optimize the location of the introduction of the alarm domain, taking into account the probability of node pollution events. In order to verify the rationality of the improved model, the traditional cover set method and the improved cover set method are applied to the same case pipe network optimization location analysis. The results show that the improved cover set method is more reasonable.
