Embodiment 1

[0039] Such as figure 1 Shown, the present invention is based on the concrete implementation mode that the chemical engineering project environmental risk evaluation system of AHP-fuzzy comprehensive evaluation adopts as follows:

[0040] (1) Establish an evaluation index system

[0041] Analyze the main process of the chemical project, and apply the Delphi expert consultation method to determine the main environmental risk factors involved in the process;

[0042] The specific implementation steps of the Delphi expert consultation method are as follows:

[0043] 1. Determine the survey topic and draw up the survey outline.

[0044] 2. Form an expert group. According to the scope of knowledge required by the subject, experts are determined, and the number is 5-20.

[0045] 3. Put forward the forecasted problems and relevant requirements to all experts.

[0046] 4. Experts put forward their own predictions based on the materials they received.

[0047] 5. Summarize the fi...

Abstract

The invention discloses an analytic hierarchy process-fuzzy comprehensive evaluation-based chemical project environmental risk evaluation system and belongs to the field of environmental risk control and management. The system comprises the following steps: (1) establishing an environmental risk evaluation index system; (2) dividing the evaluation levels of the environmental risk evaluation index system, determining the standards for evaluation of indexes under different levels, and scoring the indexes; (3) determining the weight of individual index by applying the analytic hierarchy process; (4) carrying out environmental risk comprehensive evaluation by virtue of fuzzy comprehensive evaluation to obtain a decision set; and (5) evaluating the decision set according to the maximum membership principle to obtain the environmental risk evaluation level. According to the technical scheme disclosed by the invention, the system is suitable for risk evaluation of environmental behaviors in all chemical project production processes, can be used for comprehensive risk evaluation, and is comprehensive in evaluation range, perfect in method and system, accurate in evaluation system and good in feasibility.

Description

technical field [0001] The invention relates to the field of environmental risk control and management, and more specifically, to an environmental risk evaluation system for chemical engineering projects based on analytic hierarchy process-fuzzy comprehensive evaluation. Background technique [0002] The chemical industry occupies an important position in the national economy of various countries, and is the basic industry and pillar industry of many countries. The development speed and scale of the chemical industry have a direct impact on all sectors of the social economy, and the world's annual output value of chemical products has exceeded 1.5 trillion US dollars. The chemical industry is a major polluter due to its wide variety, complex processes, and diverse products. At the same time, chemical products may produce a large amount of toxic substances in various links such as processing, storage, use and waste disposal, which will affect the ecological environment and e...
