Abstract
Water is the source of all things, so it can be said that without the sustainable development of water resources, there can be no sustainable development of human beings. In recent years, sudden water pollution accidents have occurred frequently. Emergency response plan optimization is the key to handling accidents. Nevertheless, the non-linear relationship between various indicators and emergency plans has greatly prevented researchers from making reasonable assessments. Thus, an integrated assessment method is proposed by incorporating an improved technique for order preference by similarity to ideal solution, Shannon entropy and a Coordinated development degree model to evaluate emergency plans. The Shannon entropy method was used to analyze different types of index values. TOPSIS is used to calculate the relative closeness to the ideal solution. The coordinated development degree model is applied to express the relationship between the relative closeness and inhomogeneity of the emergency plan. This method is tested in the decision support system of the Middle Route Construction and Administration Bureau, China. By considering the different nature of the indicators, the integrated assessment method is eventually proven as a highly realistic method for assessing emergency plans. The advantages of this method are more prominent when there are more indicators of the evaluation object and the nature of each indicator is quite different. In summary, this integrated assessment method can provide a targeted reference or guidance for emergency control decision makers.

Summary
Sustainability has become an important topic in the political agenda of many countries [1,2,3]. In the decision-making model, the rationality of the emergency plan for sudden water pollution accidents is determined by analyzing the important indicators affecting sudden water pollution accidents through the technique for order preference by similarity to ideal solution (TOPSIS) [24,25,26], fuzzy fault tree analysis [27,28], the vulnerability model [29], multi-criteria analysis [30], and other decision methods. This study develops an integrated assessment method of emergency plans for sudden water pollution accidents based on an improved TOPSIS and Shannon entropy method, which can effectively compensate for this drawback.
