Problems solved by technology

[0003] Existing risk assessment methods for hazardous waste treatment processes only divide the entire process into sub-processes to identify risk factors, without classifying and identifying factors. The perspective of risk assessment is single, and the final result is not accurate enough.

Embodiment Construction

[0025] The invention combines the rough set and the GRNN algorithm to evaluate the risk of the hazardous waste treatment flow. First, identify the risk factors in the hazardous waste treatment process from the perspectives of human factors (H), technology (T), organization (O), environment (E), and process (P), and then use rough sets to predict the set of risk factors. Finally, the GRNN algorithm is used to determine the risk assessment results of the hazardous waste treatment process. Concrete steps of the present invention are as figure 1 shown, including:

[0026] Step 1. Establish a risk indicator system for the hazardous waste treatment process, including:

[0027] Step 11. Determine the hazardous waste treatment process, and split the hazardous waste treatment process into multiple sub-processes; according to figure 2 As shown in the commonly used hazardous waste treatment process, the hazardous treatment sorting process can be divided into collection, transportatio...

Abstract

The invention relates to the field of hazardous waste disposal, and discloses a risk assessment method for hazardous waste disposal process based on rough set-GRNN algorithm, which identifies risks from multiple angles to more effectively manage and control the hazardous waste disposal process. The steps of the present invention firstly establish a risk index system for the hazardous waste treatment process, including: determining the hazardous waste treatment process, and splitting the hazardous process process into multiple sub-processes; identifying each sub-process from the perspectives of environment, human factors, technology, organization, and process Existing risk influencing factors; determine the specific evaluation indicators of risk influencing factors, and obtain a risk factor set composed of evaluation indicators; then use rough set to screen the risk influencing factors in the hazardous waste treatment process; finally, based on the GRNN algorithm and the filtered The risk impact factors calculate the risk assessment value. The invention is suitable for risk assessment of the hazardous waste disposal process.

Description

technical field [0001] The invention relates to the field of hazardous waste disposal, in particular to a risk assessment method for hazardous waste disposal process based on rough set-GRNN algorithm. Background technique [0002] With the development of industry, the hazardous waste (referred to as: hazardous waste) discharged in the industrial production process is increasing day by day. It is estimated that the world produces hundreds of millions of tons of hazardous waste every year. Due to the serious pollution and potential serious impact of hazardous waste, hazardous waste has been called "political waste" in industrially developed countries. The public is very sensitive to the problem of hazardous waste and opposes the establishment of hazardous waste disposal sites in the areas where they live. The disposal cost of hazardous waste is high, and some enterprises do not comply with the relevant national regulations on hazardous waste in the treatment of hazardous wast...
