The safety analysis is important link of the software development.Currently, safety within the software development the analysis usually designs from the essentials even the detailed design just starts after.Thus, neglect from the result of requirement analysis in should start the safety problem of the advertent software system module.Moreover, the software system module that get from the result of requirement analysis, its different and important degree affects the resources of the software follow-up development stage allotment problem directly again.See thus, for the requirement analysis the safety of the software system module that as a result gain analysis, and it's the problem that can't neglect that importance measure.This text aim at study how to the requirement analysis after gain of the software system module carry on the safety analysis, elaborate how to pass the importance that the safety analysis defines each module, thus, pass these to analyze better guide the software development after expect the stage to carry on.The thesis gives the state of the art of research on safety, and the concepts and the index signs of the system safety. Evaluate the aspect in the risk, discuss the step of the RAC implement, study the principle of the RAC grade assurance, introduce to use to add the power index number method the certain risk evaluates the method of the matrix;Study the PRA implement step,and two the class PRA risk section etc. problem. Combine at according to the safety analysis frame foundation of the trouble mechanism up; elaborated to aim at the safety analysis theories of the need analysis, the importance that leads to go in to analyze the result according to the safety judges the method. Design and carried out a calculator assistance safety analysis tool prototype. That software synthesized PHL, PHA, SSHA, SHA, FTA, risk assessment and evaluate with importance function.
