Evaluation Model of System Survivability

摘要

This paper puts forward a survivability evaluation model, SQEM(Survivability Quantitative Evaluation Model), based on lucubrating the main method existed. Then it defines the measurement factors and parses the survivability mathematically, introduces state change probability and the idea of setting the weights of survivability factors dynamically into the evaluating process of SQEM, which improved the accuracy of evaluation. An example is presented to illustrate the way SQEM works, which demonstrated the validity and feasibility of the method.
