A New Method for Computing Survival Signature Based on Extended Universal Generating Function

The survival signature, a new approach introduced by Coolen, has been used as an effective method to quantify the complex system's reliability as it requires less computation cost than other algorithms. This paper develops a new method for computing the exact survival signature based on the system reliability block diagram by extending the universal generating function (UGF). And verification example and comparisons with enumerative method are presented for its correctness and efficiency.
