Post Proiect Evaluation Research On Comprehensive Process Of Video Monitoring System Construction For Urban Region

With the rapid development of our social economy, the people’s material and spiritual life level have been gradually improved. But as a result of the present stage in our country is still in the transitional period of economic and social development, production development is not balanced among regions, and the public security system is still relatively weak relatively. Major criminal cases and public security incidents happen occasionally. It caused a heavy loss of life and property safety and had seriously influenced the healthy and sustainable development of the national economy. According to the relevant provisions of the ministry of public security, all the cities in our country should be gradually expand the construction of public security emergency command system. The emergency command video monitoring system plays an important role in the whole emergency command system. So it is necessary to combine the specific construction project to research post evaluation of video monitoring system construction project during decision-making, implementation and operation of management in the whole process. And construct a kind of universality of scientific and reasonable evaluation method. First, evaluate the efficacy of the construction project success degree from the perspective of qualitative, and then the classical mathematical model is applied to make further quantitative evaluation, and correct the whole process of all the effect degree of technology project construction management method timely and dynamically. It has a great significance in video monitoring system construction projects and the sustainable development of the society.Based on the research of success degree evaluation of construction during the whole process, the multi-level grey evaluation method is applied to the research of success degree evaluation to have a better effect, and it provides theoretical foundation to the evaluation. In combination with the project of the video monitoring system construction in X District of Ningbo city, the multi-level gray evaluation method is used in the period of decision, implementation and operating to evaluate the success degree of construction engineering to determine the corresponding evaluation index and evaluation mode. Besides, the engineering case is given in the general evaluation steps. It can ensure the continuous construction of video monitoring system as a whole, optimize of management and health operations in urban area. The post project evaluation research on comprehensive process of construction engineering based on grey theory is proved to be a great scientific, practical and effective method during the analysis of the engineering example.
