摘要:

针对城市供水系统中突发的污染事件,提出了供水管网水质监测点布置方法.利用混合整数规划模型表达了多目标水质监测点布置,通过模拟管网发生的水质污染事件,计算管网发生污染事件时对用户带来的影响值,利用改进的贪心随机自适应性搜索算法对模型求解,并结合ZJ市管网,验证了该算法对模型的求解效率,提出了该市基于突发污染事件的管网水质监测点优化布置方案.

Abstract:

An approach for optimal layout of monitoring stations was presented to monitor the accidental contaminations in water distribution system.A mixedinteger programming model was used to express the multiobjective monitoring stations placement.Through the simulation of accidental contaminations in water distribution system,the impact of the contaminations was calculated.The improved greedy randomized adaptive search procedure was used to solve the model,and the efficiency of the algorithm was verified by the testing of ZJ water distribution system.Based on an analysis of the results,the optimization locating of the monitoring stations of ZJ water distribution system was presented.
