Research of China Unicom on the evaluation system of urban safety status and safe operation of enterprises,2023
In recent years,with the increasing scale of cities and the frequent occurrence of risky accidents,in order to improve control capabilities of urban risks and build an emergency management collaborative response mechanism,for every major city it is ur-gent to use digital means to build a digital map of the urban security status.Based on the dynamic and static urban data of District G of City A,a universal method for constructing regional security status evaluation is proposed in this article,which relatively scientifically reflects the different risk situations of different areas in the digital map.The evaluation method is based on the triangle theory of public safety science,the entropy weight method is used to weight,and the fuzzy evaluation method is used to grade the hazard,the vulnerabili-ty of carriers,and the emergency response capability in the face of accidents of every region in the study region.The study results have been applied to the digital map of urban security status in the local e-government system under construction.
