英文摘要

      In recent years, sudden water pollution incidents have occurred frequently, seriously endangering residents’ health. By placing sensors in the water supply networks to monitor the water quality, some characteristics of contamination source including the location, quality and occurrence time can be quickly identified, which is conducive to the relevant departments to deal with the diffusion of pollution. Therefore, the research on the contamination source identification has important practical significance. With the wide application of intelligent optimization algorithms in engineering problems, using simulation-optimization method to solve contamination source identification problem has become a hot research field. In this paper, the model of this problem and the abstract mathematical model are given, and then the general method of solving the problem with simulation-optimization method is described. Through in-depth analysis of this problem, the paper concludes that it is multimodal, computing expensive and uncertain. Based on these three characteristics, this paper focuses on the representative research results of intelligent optimization algorithms in contamination source identification problem, and finally points out some directions and contents to be further studied.
