Abstract:

The Event-Based Reliability Model EBRM was developed to model and analyze the reliability of a network in which component failures are statistically dependent. In EBRM, the events that could cause component failures were modeled explicitly. This approach had the great advantage that it required much less parameters than the traditional model employing conditional probabilities. The EBRM was also proved to be a completely general model which could be applied to any kind of failure dependencies. For reliability evaluations, many existing algorithms for computing network reliability could be used with minor modifications and no significant increase in computational complexity. An improved algorithm for the appropriate evaluation of network performance was alos developed. For multi-state systems, ordered enumeration was used to approximate and bound system reliabilities and other performance measures, and an efficient algorithm was developed for this purpose. Author
