The Research Of Safety Inputs Decision Method Base On The Safety Rehology-mutation Theory

This text takes basis on absorbing international safety inputs theories of the research, also it makes deep research on the relation ship of safety inputs and system safety degree. we analyze the main factor of system, the character of safety, safety degree of system, Safe and economic behavior, safety inputs and content, safety inputs theories, safety inputs indexsign system, safety inputs evaluate, and combines the actual circumstance of our country in the process of study, take research on the direction and amount of safety inputs, Put forward to method and criterion of sefety inputs. The safety rehology-mutation law of system under the condition of safety inputs lack is described with the model of Logistic. It is analyzed that the Maximum system safety degree and ratio attenuation of system safety degree influence to system safety degree. It is shown through Positive study that the model of Logistic can describe the evolution law of system safety under the condition of safety,so it is very important for our country's production.
