Psychological Evaluation of Substation Maintenance Staff Based on Improved Fuzzy Evaluation
A large number of statistics of electric power accidents show that psychological factors are the main causes of acci-dents.Therefore,psychological evaluation of electric power employees has important practical application value.In order to evaluate the safety psychology of electric power employees more accurately,a safety psychology evaluation method based on improved fuzzy comprehensive evaluation algorithm is proposed.Firstly,the safety psychological evaluation index system is constructed according to the relevant literature research and the questionnaire survey of electric power employees,and the index score is quantified.The entropy weight-analytic hierarchy process is used to assign weight to the index combination,and the traditional fuzzy comprehensive evaluation method is improved based on the validity principle and weighted average principle.Finally,the improved fuzzy compre-hensive evaluation model is used to evaluate the psychological evaluation data.By comparing the evaluation results of the model be-fore and after the improvement with the performance appraisal results of the last quarter,it shows that the improved model can de-scribe the safety psychological state of electric power employees more accurately than the traditional fuzzy comprehensive evaluation model.
