Comprehensive evaluation method for effectiveness of in-use safety helmets of operation personnel of metallurgical enterprises

Abstract

The invention relates to a comprehensive evaluation method for the effectiveness of in-use safety helmets of operation personnel of metallurgical enterprises. The method comprises the steps of establishing a comprehensive evaluation index system for the effectiveness of the in-use safety helmets, constructing a factor set and a weight set of evaluation indexes at various levels, and determining weight vectors and weights of factors included in the evaluation indexes at various levels by using an analytic hierarchy process; determining a membership degree of all third-level indexes to comment set elements according to an established comment set, constructing an evaluation matrix, corresponding to the third-level indexes, of all second-level indexes , and conducting first-level fuzzy evaluation by utilizing the evaluation matrix, corresponding to the third-level indexes, of the second-level indexes and the weight vectors of the factors included in the second indexes; conducting second-level and third-level fuzzy evaluation on first-level indexes and evaluation targets in sequence, and determining the safety levels of the evaluation targets according to third-level fuzzy evaluation results of the evaluation targets. Compared with existing evaluation methods, the method has the advantages that the effectiveness of the in-use safety helmets in the metallurgical enterprises is more comprehensively, reasonably and accurately evaluated, and a clear direction is pointed out for improving the effectiveness of the in-use safety helmets of the evaluation objects.

Description

technical field [0001] The invention proposes an evaluation method aiming at the effectiveness of safety helmets used by field workers in iron and steel metallurgical production, and belongs to the field of data processing and evaluation. Background technique [0002] In the metallurgical industry, due to the complex operating environment, high-altitude operations and three-dimensional cross-over operations, frequent lifting injuries, high-altitude falls, and object strike accidents occur frequently. Workers at the production site must wear safety helmets. However, due to the lack of understanding of the role of safety helmets by some iron and steel metallurgical enterprises and production site operators, some iron and steel metallurgical enterprise production site operators are not effective in using safety helmets. Correctly wearing helmets and other issues, and there have been many accidents that caused injuries to the workers' heads. Therefore, in order to effectively ...
