specific Embodiment

[0146] In this specific example, the initial flow rate of the main canal on the central line is 70% of the design flow rate, and a sudden water pollution accident occurs from the control gate of Yanling River to the control gate of Qihe River. It is a hypothetical non-degradable substance with a pollution amount of 10t, which can be disposed in the ditch pond, and there is a Tanzhai water diversion between the two control gates. It can be known from the calculation that the time for pollutants to reach the control gates of the Qi River and the Shierli River are 20 and 180 minutes, respectively. Therefore, if two scenarios are set in the accident drainage pond, two scenarios are set in the upstream section of the accident drainage pond, and one scenario is set in the downstream section of the accident drainage pond, there are four emergency plans in total (Table 4).

Abstract

The invention discloses an emergency plan evaluation method based on an improved TOPSIS method, which relates to the technical field of emergency plan evaluation and analysis. This method takes the emergency plan of water pollution accident as the research object and takes the emergency plan of water pollution accident as the research object, Based on the benefit index and cost index, the evaluation system is established, and the optimal emergency plan for water pollution emergencies is determined by the improved TOPSIS method.In the determination of index weights, the combination of AHP method and entropy method can get more reasonable and accurate index weights. Therefore, the evaluation method provided by the invention can provide better guidance for determining a more reasonable, scientific and effective optimal emergency plan. It solves the problem that the existing emergency plan research is mainly to study the preparation of the plan and recommendations, but can not determine the optimal plan, and provides technical support for better response to sudden environmental pollution events.

Description

technical field [0001] The invention relates to the technical field of emergency plan evaluation and analysis for emergencies, in particular to an emergency plan evaluation method based on the improved TOPSIS method. Background technique [0002] The objective existence of the uneven distribution of water resources and the unbalanced water demand of human society make water diversion projects inevitable. Since entering the 21st century, my country has entered a stage of rapid urbanization, the pressure on the environment is increasing, and environmental emergencies occur frequently. In particular, heavy and extraordinarily large sudden environmental pollution incidents have brought huge damage to the country and people. After the accident, whether effective rescue measures can be taken in a timely manner, favorable emergency command can be carried out, whether various rescue materials can be in place in time, etc., these problems actually reflect the necessity of establishi...
