The dangerous events often happen in coal-fired power plant and its influence is very serious. Use entropy weigh method to determine the weight of index is very popular, it not only consider the key factors but also make a quantitative analysis for the interaction and coordination among different index. It is about how to make the function of system security greater than the sum of each single subsystem. The case study shows that the comprehensive safety evaluation model can integrate the safety factor and analyze the nonlinear effect of each index so as to make the evaluation result more reasonable, then, it can supply the scientific basis for safety production management of enterprise.

Comprehensive Evaluation Model

At present, various public emergencies occur frequently around the world, and the world has entered the stage of a “high-risk society”. Urban community as the carrier of all kinds of public emergencies, its role has become increasingly prominent and become the focus of the current research, but in the urban community emergency management capacity evaluation system, the related studies are still less. To more effectively identify the key internal and external factors that affect the emergency management ability of the urban community, and evaluate scientifically and effectively, on the basis of the existing studies, the evaluation index system of community emergency management capability was established according to the emergency management cycle theory. In view of the complexity and fuzziness of the emergency management capability of the urban community, a multi-layer fuzzy comprehensive evaluation model based on entropy weight was established, and the emergency management capability evaluation of community was carried out under the background of the public emergency event of COVID-19 epidemic. The results show that the evaluation results and improvement suggestions of the multi-layer fuzzy comprehensive evaluation model based on entropy weight are consistent with the actual situation, indicating that the index system and the selected method are reasonable and effective. This study provides a new decision-making idea and method for the evaluation of urban community emergency management capability, and has high application value.

In this article, the entropy weight and fuzzy comprehensive evaluation methods is applied to Ecological Benefit of cold-formed thin-walled steel residential structure. Designed indicators system of Ecological benefits about cold-formed thin-walled steel residential structure, we divided into nine indicators in the system, then we grant questionnaire through selecting experts of project benefits Evaluation and experts on study about cold-formed thin-walled steel residential structure, Scoring the importance of eco-efficiency indicators, Using the Entropy weight to determine the weights of evaluation indexes, then combining with fuzzy comprehensive evaluation model, comprehensive evaluation on a variety of factors is made, analyzing ecological benefits about cold-formed thin-walled steel residential structure, eventually the result of Comprehensive Evaluation of Ecological benefits about cold-formed thin-walled steel residential structure is obtained.

In the paper, we establish an evaluation system in the study of four aspects such as people, regulation, equipment and technology management, field management and engineering construction. We present an entropy weight multi-level fuzzy comprehensive evaluation model in power plant security on the basis of reliability identification. Firstly, it identifies the reliability of power plant security evaluation system. Secondly, it can meet the condition that the system is reliable. Then it obtains the indicator weight of all levels in the evaluation system by the entropy weight method. Finally, it carries out a comprehensive evaluation in power plant security by the multi-level fuzzy evaluation method.

Abstract The extent of reservoir sedimentation is an important index related to the functional operation of reservoirs. Therefore, it is vital to accurately conduct sedimentary assessment. In this paper, the analytic hierarchy process was used to determine subjective weights, gray correlation analysis and entropy weight method were used to determine objective weights. The combination weights obtained using optimized combination weighting method based on genetic algorithm were more suitable for the comprehensive analysis of the impact of reservoir sedimentation. This was then used to constructed a multi-level fuzzy comprehensive evaluation model based on improved cloud model. A reservoir was selected as the study object, and its sedimentation impact level was evaluated: the numerical characteristics of the stratus cloud of the comment on the impact of the reservoir sedimentation were (0.6372, 0.0664, 0.0795). The results showed that the reservoir sedimentation is considered as severe influence, and the sedimentation has become a major problem that needed to be solved urgently. The results of this paper could provide insight for reservoir research domestically and abroad. Furthermore, it could also enable managers to more accurately grasp the severity of reservoir sedimentation.
