Theory of fuzzy comprehensive evaluation of the level of police information

Abstract: This paper analyzes the content of police Information technology and construction goals, the establishment of the Police Information evaluation index system, gives the police the Information based on fuzzy evaluation of the level of calculation.

Paper Keywords: police Information, the evaluation index system, fuzzy theory
In the 21st century, Information technology is characterized by the Internet fundamentally changed the way people work life, human society into the information technology course. To the "Golden Shield Project" as the focus of police information is the construction of electricity to government An important aspect is the basis for national construction. how to effectively police information technology, scientific evaluation and description of police work to achieve the level of information for decision-making at all levels of leadership to provide technical support to a current need to address reality.

1 Police Information and the goal of building the content
Evaluation of the police information, we must first clear the content of police information. Only the concept of information in the police clear a clear extension of the premise to the construction of police information to a proper understanding and evaluation. In the domestic academic community , the definition of representative: "Police Information is the modern computer technology, communication technology, network technology widely used in police work and promotion." "information security work is the basis of certain forms of information to the public security gradually penetrated all levels of work and become the main elements of public security work, the gradual growth process. "" the public security police as an important information, using modern information technology, public security departments at all levels, equipment, well on the way to transform the traditional police to form a high-performance public security administrative system to enhance rapid response to public security organs, the ability of coordinated operations to meet the social and public expectations of the public security organs. "" Public information is an integral part of the information society. is the police officers in various police activities . generally acquire the intellectual tools of information technology-based, full development and utilization of information resources, thus greatly improving combat effectiveness and efficiency of public security. promote the modernization of police Shen} mechanism to learn of the development process. including information resources, information network, information technology, application of information technology, information technology personnel, information technology standards to run the 6 aspects. "
In summary, I believe that police information is the use of computer, Internet and other modern information technology. The police work and the process integration and online implementation, the full development potential of the police information resources, to enhance the effectiveness of police work. Police Information is the goal of building modern policing is a gradual building process. Police information technology's ultimate goal is to enhance the performance of public security work, to serve the community. Therefore, the police information technology is not just the introduction of modern information technology, and related organizations, including the transformation of business processes.


2 Police Information Index System Level Measurement principle
Indicator system in order to pass the information on the police to conduct a comprehensive assessment of the level, when building the following three principles.

2.1 Scientific phase-end units with the system
Any indicator system should be based on a theoretical basis, science is to develop the most basic principles of index system, police information index system is based on the level of information and the theory of police information. Meanwhile, the police Information Services is a systems engineering point of view should be based system for analysis of police information. through the system-level division, the value of police of the overall structure of interest rates, features a more thorough understanding, but in the specific comparison can be for the characteristics of each project to take a different approach. of police information to be separated from the system level to comply with the basic logic, rather than a simple list of data, collection or stack. for different levels and the role of project selection indicators should be closely combined with the reality of the situation of police information, data selection, calculation of the synthetic to the accepted scientific theory as the basis, measure results to ensure that police information to reflect actual.

2.2 on behalf of the praise of combining with the operational
Indicator system should be a series of interrelated and mutually complementary unified whole composed of indicators. Constitute a target indicator system should be able to simplify the complex phenomenon that reflects the information, either directly derived from the original data, and to reflect subsystem characteristics, basic indicators can also be in the abstract and summary, based on the use of "than" the "degree" so that indicators, to illustrate the intrinsic link target subsystem. describe the level of police information are many factors The index system is not as systematic bigger the better, therefore, many available indicators in a representative selection, flexibility, leading indicators. The leading indicators not only have a relatively clear meaning, to be more accurate to describe the expression of content and objective of the problem, but also be able to easily obtain a more accurate and reliable data, with statistics, operational, to as little as possible to achieve the target completion of the purpose of evaluation.

2.3 comparable with the phase-Results-oriented units
Through horizontal, vertical comparison is to design indicators and an important part in the actual operation. Selected indicators are not comparable to factor into comparable factors, and target diameter to ensure the consistency of the index system can not only horizontally between the public security organs comparison, but also a public security organ for a time series for the longitudinal comparison, in order to facilitate the development of police information technology trends Research and exploration. to maximize the index system of guidance in the implementation process and guiding role in promoting police rapid increase in the level of information.


3 Police Information Evaluation Index System
Select metrics information from the dim connotation of service, select those targeted indicators. Police Information building is a dynamic input output management process. Therefore, the index system to police the information infrastructure, information resources development and utilization of information technology personnel and staff quality, information input output four elements as the standard, constitute three levels of four major categories of 27 indicators of police information index system, shown in Figure 1.

(1) information infrastructure is the material basis of police information, but also play the role of information resources necessary prerequisite. At this stage, the level of police information is still in the initial stage, the public security organs in the information infrastructure on a large number of investment, therefore, the information infrastructure is the current level of information to police an important measure of the standard. specific target consists of two parts: First, infrastructure targets, including police officers have a number of computers per hundred people, every hundred have telephone machine number, the computer networking degree, police level of professional software applications, and second, the construction of indicators of network systems, including access Intemet way, the bandwidth of the interface with the Intemet, the public security organs of online information dissemination methods, the level of public security organs in website construction, website The total capacity of the server.

(3) information technology personnel and the quality of police officers claim the successful implementation of information standards, all other factors have a decisive impact. Awareness of information management is to determine the level of information the public security organs important factor, it is a important indicators, information technology personnel situation, the specific conditions set by information technology sector, information technology staff per hundred the number of information technology staff qualifications and other indicators to reflect the quality of police officers claim, every hundred undergraduate education by the numbers of people an index to reflect.

(4) A police information technology level of output reflects the input of the effect of police information, and can predict the development of police information. Specific target is divided into two parts: First, the absolute value of inputs, two is the relative value of inputs, including the annual information technology and skills for police training costs and their share of the public security organs in the proportion of the cost of education and training, information the number of financial investment, infrastructure construction, social public satisfaction with public security organs, high technology crime detection rate, the information office of the public security organs to bring the amount of financial savings.

In this index system, some indicators are "fuzzy". But the so-called "fuzzy" does not mean its content is not clear, but that these indicators are more suitable for evaluation using qualitative methods, and then the results of the assessment quantitative scoring, to achieve the specific number of quantitative indicators.

Level 4 Evaluation of police information
4.1 Police Information bearing in mind the comprehensive evaluation method
Evaluation method according to subject areas covered, you can evaluate the current methods commonly used in China are divided into expert evaluation, economic modeling, operations Research methods, mathematical methods and a combination of other methods of cross-type five categories, each category can be divided into a variety of methods.

(1) expert evaluation method is based on expert judgments based on subjective evaluation method of a class, including scores, analogy and correlation coefficient and other specific methods. Expert evaluation method is simple, intuitive and strong characteristics that can be economic indicators for the qualitative or quantitative evaluation.

(2) economic model to evaluate the method is a kind of quantitative evaluation methods, with objectivity, utility and high degree suitable for the evaluation of direct economic benefits. Kind of evaluation methods including the production function method, index formula and costs - - benefit analysis and so on.

(3) mathematics, including mathematics, multi-objective decision making, data envelopment analysis (DEA), Analytic Hierarchy Process (AHP), fuzzy evaluation, multivariate statistical analysis, principal component analysis (PAc), factor analysis and cluster analysis, etc. . it has a complete theoretical basis for claims of more a result of changes in quantitative dynamic analysis and commentary, especially those with uncertainty, fuzzy due to cable to get a better assessment of the evaluation results. The main drawback is due to factors arising from the work of the home more than great to deal with difficulties.

(4) combination of the aforementioned evaluation method is the expert evaluation, economic modeling, operations Research and other mathematical evaluation method in the evaluation of specific models or methods of application of organic mix, and avoid weaknesses of an evaluation method. Which, APF method is a species is very typical combination evaluation method, it analyzes the level (AHP), multivariate statistical analysis of the principal component (PAC) and Fuzzy (Fuzzy) and other methods are combined, comprehensive utilization of the different characteristics of various methods to make the object of evaluation more comprehensive evaluation. Police Information Police evaluate information according to which the different stages of a targeted selection of evaluation methods to evaluate.

4.2 The comprehensive evaluation index system of the basic framework
In general, indicators of police information and more comprehensive evaluation of the work includes three aspects: First, a comprehensive evaluation index system and evaluation criteria established, which is a prerequisite for the evaluation, the second is qualitative or quantitative methods used to determine The specific value of each index, the index evaluation value and the third is the evaluation value of the consolidated, including the right to re-synthesis algorithm and the determination of Final Adjudication value calculation.

4.3 Police Information fuzzy comprehensive evaluation method
As the evaluation index system of police information, there are difficult to accurately describe many of the indicators, for this paper, fuzzy comprehensive evaluation method based on a comprehensive evaluation of police information. The index system of the degree of influence of each factor is different, according to the the evaluation index, with the level of analysis, to determine its weight. assumes the weight to claims of Wi (i = 1,2, ..., n), which constitute the weight matrix W

Then for each element of a comprehensive evaluation rating given by a statistical expert advice, evaluation value calculation I-Cable expressed to the judge on the j-level evaluation results, which is equal to the i-j element of evaluation grades for the first number of the proportion of the total number of judges. This constitutes an evaluation matrix R.


With elements of weight matrix and the evaluation matrix set, you can use fuzzy matrix synthesis method fuzzy comprehensive evaluation matrix B
