Evaluation Criteria for Reliability in Computer Systems

Numerical methods, particularly finite element methods, are widely used in solving different problems. Since these methods are approximate, having a real understanding of the distribution of errors is extremely important. With the increasing number of users, the number of cause dfailuresin creases by their fault. In this article we will discuss per formance evaluation system, the performance evaluation of computer and communication systems for quality research that is finding its profit goals for the number of ways to predict the behavior of the system. One of the main parameters in determining the performance evaluation is reliability and because some complex systems cannot be easily modeled by hybrid methods (RBD), we use Markov method.
