On the Evaluation of the Reliability of k-out-of-n Systems

The paper provides some correcting remarks on several methods to determine the k-out-of-n:G system reliability - a problem that has taken more than its share in the literature. A Jain-Gopal paper presents two algorithms JG-1 and JG-2 to evaluate the reliability of a k-out-of-n System. The comparison of the computational costs of JG-1 with those of JG-2 and with other existing algorithms, especially Barlow-Heidtmann, need to be restated.
