| Abstract: | For addressing the accuracy and calculation problem in reliability estimation, an orthogonal polynomial sequence approximation of the reliability distribution function is presented at first. Then the reliability function of a parallel exponential -life system is approximated using this method. It is shown that the result is quite convenient to compute and has a high precision at the same time. |
