Evaluation of the Emergency Capability of Subway Shield Construction Based on Cloud Model

Abstract

We aimed to enable an accurate assessment of the emergency capability of subway shield construction, and promote the construction of emergency capability of enterprises, so as to better guarantee the sustainable development of subway shield construction. In this paper, the cloud model is used to evaluate the emergency capability of subway shield construction. First, based on the emergency work of subway shield construction, this paper constructs an evaluation index system for the emergency capability of subway shield construction, with four first-grade indices and 23 second-grade indices. Second, the subjective and objective combination of the DEMATEL and entropy weight methods are used to determine the index weight. At the same time, a cloud model is introduced to construct a model for the evaluation of the emergency capability of subway shield construction. Finally, a case study is carried out, and the results show that this evaluation model can be used to accurately evaluate the emergency capability of subway shield construction, and can determine its level and obtain the cloud map of the emergency capability of subway shield construction of the enterprise. From the evaluation results, we can find the weak links and existing problems in the emergency capability of subway shield construction, which will help enterprises to take improvement measures. The evaluation results are broadly consistent with the conclusions of the annual work report on enterprise emergency management, verifying the scientificity and effectiveness of the evaluation method.
