Uranium tailings decommissioning environment management effect assessment method based on three-scale analytic hierarchy process

Abstract

Provided is a uranium tailings decommissioning environment management effect assessment method based on a three-scale analytic hierarchy process. Based on the conventional environment management performance assessment method, a uranium tailings decommissioning environment management effect assessment system is established. The weight is determined by employing the three-scale analytic hierarchy process, a comparison matrix is improved, the consistency test is avoided, the iteration frequency is reduced, and the convergence speed is increased; a membership function is established by employing a triangle distribution function; and the decommissioning environment management effect comprehensive assessment is conducted, the management scheme is improved, and the management effect is improved.

Description

technical field [0001] The invention belongs to the technical field of information processing, and relates to a three-scale analytic hierarchy process-based evaluation method for the decommissioning environment of uranium tailing ponds. Background technique [0002] For the decommissioned uranium tailings ponds, some treatment has been carried out at home and abroad. Foreign countries use the environmental economic forecast analysis method and the logical framework method to evaluate the economic benefits generated in the environmental treatment of uranium mines. With the improvement of environmental protection awareness , People's effect of environmental governance is more and more inclined to environmental improvement, rather than the economic benefits generated in the process of environmental governance. In terms of evaluation of governance effects, there is no reasonable and ready-made evaluation system in China, but in other environmental governance, there are certain e...

Problems solved by technology

[0020] 1) The traditional AHP method is a criterion-based decision-making method that combines qualitative and quantitative analysis, in which the subjective factors of experts dominate, which will affect the objectivity of the evaluation results. When performing a matrix consistency test, if the judgment matrix If there is no consistency, the judgment matrix must be reconstructed until the consistency check is passed. It is an iterative process with a large amount of calculation and low precision.

[0021] 2) The result obtained in the comprehensive evaluation model is a fuzzy vector, which cannot be compared with different evaluation objects
