At present, the evaluation of risk management criteria——acceptable risk criteria has not been established, which limits the application of our risk management and development. Reasonable acceptable risk criteria is one of the key issues for risk assessment, is an important basis for the quantitative risk assessment. And it can resolve the "more security is enough security" problem. In the development of acceptable risk criteria, the criteria set by more than the actual value once, it will lead directly to a wrong decision-making behavior of managers, triggering a series of serious consequences. Therefore the acceptable risk criteria for China's risk management and risk decision-making basis, to provide reference standards for risk assessment.In the study of the acceptable risk criteria, the author first analyzes the existing method of determining the acceptable risk criteria in the domestic and international, from several related factors directly involved (ie:the objective risk, risk tolerance persons and risk provide persons) and the actual application to start, to identify ways to improve the place to be. And analyzing the principles of the development of acceptable risk criteria, the existence of the purpose and significance of the acceptable risk criteria, we can find out the shortcomings of the principle. Finally, the analysis of foreign trends in the development of the acceptable risk criteria could show out the future direction of development. For the lack of the acceptable risk criteria of the method and the principle, and the development trend, the determination of the acceptable risk criteria should that: Based on the principle of equality, based on the principle of effectiveness, based on the principle of the reality risk, the principle of difference between industries, based on the principle of dynamic principles, the principle of geographical and the principle of consultation in the related parties. And according to the principle of determination of the acceptable risk criteria, combining with China's actual situation, the following method is more reasonable:The ALARP framework of the form, and in some risk value range by venture party provider and the risk tolerance acceptable risk criteria developed in consultation provinces, municipalities own set of standards, and timely updates. In the development process, we determine some of the details described the treatment:the risk of line can be ignored, the consequences of restrictions on line, data selection, processing, industry standard and so the division. Individual acceptable risk criteria are determined on the basis of statistical mean of the scope of consultation, the risk tolerance and the risk provider consultation in consultation range. Social risk can be expressed by FN curve, and with Individual acceptable risk criteria like the same, the FN curve slope value of-1.Finally, we developed our country's acceptable risk criteria in this way. The acceptable risk criteria including:the public individual acceptable risk criteria, the employee individual acceptable risk criteria, the public social acceptable risk criteria and the employees social acceptable risk criteria.
