Large missile equipment retirement safety control method based on improved fuzzy entropy weight method

Abstract

The invention provides a large missile equipment retirement safety control method based on an improved fuzzy entropy weight method. The safety control method comprises the steps that a multi-layer hierarchical large missile equipment retirement safety risk assessment index system is constructed, a fuzzy statistical method is used for determining a fuzzy assessment matrix, a comprehensive weight iscalculated through a comprehensive entropy weight method and an analytic hierarchy method, and a multiplication-bounded operator is used for comprehensive assessment. Compared with the prior art, safety risk analysis is conducted on large missile equipment retirement disposal in processes, stages and types, the constructed multi-layer hierarchical assessment index system can ensure the integrityof input indexes of the assessment model, information repetition caused by high correlation between the assessment indexes is effectively reduced, and the workload for safety risk assessment and safety control is reduced; the comprehensive weight is calculated through the entropy weight method and the analytic hierarchy method, so that deviation caused by subjective factors is avoided, the scientificity and objectivity of the weight are improved, and comprehensive assessment of all levels of indexes corresponding to the multi-layer assessment index system is achieved.

Description

technical field [0001] The invention belongs to the technical field of security control of weapon equipment decommissioning, and more specifically, the invention relates to a large-scale missile equipment decommissioning security control method based on an improved fuzzy entropy weight method. Background technique [0002] To carry out research on the safety control methods of weaponry and equipment decommissioning, it is first necessary to extract factors related to the decommissioning safety of the assessed weaponry and equipment, then select appropriate evaluation theories and methods, conduct qualitative and quantitative analysis and statistics, and finally draw evaluation conclusions, so as to Take targeted control measures for relevant safety risks in the decommissioning process. The safety control of large-scale missile equipment decommissioning involves multiple stages and factors in the decommissioning process. At present, the research on the safety control of large...

Problems solved by technology

But at the same time, there are also the following shortcomings: 1) It cannot solve the problem of duplication of information caused by the correlation between evaluation indicators; 2) The determination of the weight of each factor has a certain degree of subjectivity; 3) The determination of the membership function in the multi-objective evaluation model is too cumbersome

However, the essence of AHP is a subjective weighting method, which is greatly affected by subjective factors, and the evaluation results are prone to deviations.
