[0058] In recent years, people have paid more and more attention to the coordination relationship between urban construction and the ecological environment in the process of social development, and it is particularly important to maintain the sustainable development of social construction. As a result, a series of urban safety implementation systems have emerged and are carried out in an orderly manner in various departments. It has been proved that the urban safety system has indeed played a great role in urban construction and development. However, the formulated systems need to be tested in practice and need to meet the development needs of enterprises. Not every system fits perfectly with the enterprise development. Therefore, it is necessary to periodically conduct a centralized evaluation of the performance data of urban safety. The existing evaluation method is to use a pre-established evaluation system to centrally evaluate all the uploaded performance data. However, the above method has the following disadvantages: Since the types of each performance data are different, using the same evaluation system for evaluation will result in the final evaluation result not conforming to the actual situation, thus causing congestion in the system modification work and affecting the development of the enterprise.
