Research On Performance Evaluation In Safety Management For ES Company Of Nuclear Power Construction Enterprise

This thesis takes the safety management performance of ES company,a nuclear power construction company,as the research object,puts forward the problems of safety management performance management in combination with the actual situation of the enterprise.For example,the process management assessment is not valued and the weight distribution is small,which can not reflect the real state of the enterprise’s internal safety management,and can not clearly reflect whether the management activities and measures in all aspects of the enterprise’s safety production can effectively control the hazards or not.This thesis conducts a comprehensive evaluation of the safety management performance of the enterprise based on the discovered problems,and improves the weak links of the enterprise’s safety management according to the comprehensive evaluation results.The essence of safety management performance evaluation is comprehensive evaluation.There are three key technologies in a comprehensive evaluation.One is the establishment of a realistic index system,the second is the determination of reliable weight,and the third is the appropriate model method.For the three key technologies,the research and processing processes are as follows.First of all,this thesis identifies 96 factors that affect the safety management performance of nuclear power construction enterprises by sorting out relevant domestic and foreign literatures.Through semantic merger and dimension reduction,ES company’s actual situation and expert discussion,the ES company’s safety management performance evaluation indicator system is established,which contains 6first-level indicators and 26 second-level indicators.Secondly,the thesis analyzes the reachable relationship between 26 secondary indexes by using the interpretative structure modeling(ISM).With the help of the ISM online computing software and multi rounds of discussion by the ISM team,the most simplified hierarchical topological diagram among 26 indexes is obtained,which is an important basis for the scoring process of the analytic network process(ANP).At the same time,the principle of precise scoring is used to effectively solve the problems of inconsistent and incomplete decision-making caused by the complexity of decision-making,the conflicts between expert decision-making preferences and goals,and non-commensurable.Then the thesis uses Super Decision(SD)software to calculate the weight of each indicator.Thirdly,the expert group is organized to score 26 indexes,and the final evaluation results are calculated by grey clustering method and fuzzy comprehensive evaluation method combined with the weight obtained by the ISM-ANP.The results show that the comprehensive performance of safety management of ES company is good,but the company pays more attention to the safety management related to hardware,the safety management related to software is relatively weak,among which the performance score of safety culture construction management is the lowest.Finally,based on the evaluation results,this thesis puts forward suggestions and countermeasures to improve the safety management of ES company,such as strengthening the new version of safety production standardization and the effective integration of various tasks,upgrading the information platform to improve the effective communication of safety information,innovating the Internet + smart construction site,the application of Building Information Modeling(BIM)and other related technologies in safety management and other improvement measures.
