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.

The risk factors of continuous incremental launching bridge during construction stage are specialized. The risk in incremental launching stage is analyzed and identified. A risk assessment index system is built. A fuzzy comprehensive evaluation model is developed. The results obtained from the risk assessment model verifies the validity and practicality of the developed method by the combination of analytic hierarchy process and fuzzy mathematics theory. Moderate risk assessment results are developed to provide references for incremental launching construction method.
