Using a Log-normal Failure Rate Distribution for Worst Case Bound Reliability Prediction

Bishop, P. G. and Bloomfield, R. E. (2003). Using a Log-normal Failure Rate Distribution for Worst Case Bound Reliability Prediction. Paper presented at the 14th IEEE International Symposium on Software Reliability Engineering (ISSRE 2003), 17 - 20 Nov 2003, Denver, Colorado.

Abstract

Prior research has suggested that the failure rates of faults follow a log normal distribution. We propose a specific model where distributions close to a log normal arise naturally from the program structure. The log normal distribution presents a problem when used in reliability growth models as it is not mathematically tractable. However we demonstrate that a worst case bound can be estimated that is less pessimistic than our earlier worst case bound theory.
