Research In Performance Evaluation For Information System Of Public Safety Emergency Management Of Cities

Presently,our country is at a crucial period of economic transition and social transformation, on the moment, China's exactly correspond to a frequent stage of "Non-steady state" in the social development sequence of spectrum which is the most serious period of bottleneck effect caused by population, resources, environment, efficiency, equity and other social contradictions according to the low of the world development process. Furthermore, the emergence of various types of public crisis (SARS,2003;Bird flu,2004) and natural disasters(Snowstorm in many province of south China,2007; When Chuan earthquake,2008) in China recent years make us aware that we must not only attach great importance to the city's disaster prevention and reduction function but also have the sense of crisis management during the rapid development of urbanization in our country.In order to effectively enhance the Emergency Management ability and efficiency which the government used to protect the city public safety, and minimize the harm and loss caused by various types of disasters and accidents, major cities are urgently needed to establish a results-oriented and constantly improved operation and the management mechanism of city emergency management system. At the present time, there's no continuous evaluation of effectiveness of operations but one-time acceptance assessment to be aimed at system performance in monitoring system of city emergency security system all over our country. This situation induce governments difficult to clarify whether the city emergency systems achieved the desired results, and then make high-level planning departments couldn't understanding the status quo of the development of the city emergency security systems clearly and accurately, in that case, hard to make reasonable decision-makings for the next step of the development.This paper is in connection with the distinguishing feature of Chinese city emergency system construction, try to establish a suite of performance evaluation mechanism for city emergency security system includes basic indicators and appraisal models which could make targeted-improvement on city emergency security system based on it's actual operation results,, in order to achieve closed-loop management for city emergency security system.At first, this paper take a comparative study on several existing relative-mature performance evaluation mechanism for city emergency security system and management information system, analyze it's applicability and limitations for China's national conditions and common features of performance evaluation mechanism for management information system reflected through these systems. On this basis, combine with the author's research from China's Public Safety Emergency Management Information System, I designed basic indicators that applicable to the system-performance evaluation for public safety system of our country, and take an in-depth study on the quantitative methods of these basic indicators, in thus built a indicators quantitative method based on fuzzy-dimensionless and maturity model, designed detailed acquisition and quantitative methods for all indicators, as a result, I have established a actual operational quantitative rating system, and so that laid a foundation for ensure the objectivity and practicality of the whole system.To proceed, this paper established a comprehensive evaluation modal of city emergency security system which based on AHP and cluster analysis. In particular, it use AHP to determine weight, make the weighted grade summary from the three indicators to the level indicators, then draw on the thinking of the cluster analysis, take the synthesis algorithm which use the Euclidean distance between the actual performance-point and the optimal performance-point as level indicator. Because one of the main purpose of performance evaluation is to make clear its current status of the unit be estimated and to determine the gap between it and the best state, thereby clair the direction and space of its own development. For this demand, the paper established a performance evaluation space which use the point in it as the optimal performance-point and current performance-point of the system to clear out the gap between them so that to carry out the full account of the performance level.Lastly, on the basis of the confirm of basic indicators and evaluation, in order that public safety emergency management information system of every single city use the results of performance evaluation as the basis of maintenance and improvement in system operation and management, analyze the actual results of system to find out the main problems. This paper research in applications of performance evaluation in system operation and management, established an identity and sorting algorithm for main problem which impact the performance based on the evaluation results, and use the indentify problems to provide two kinds of management advice method which called norms and case-for relevant departments. Finally achieved the closed-loop management for the phases of construction and operation management.
