• ### Goodness-of-fit tests for the power-law process

Publication Year: 1992, Page(s):107 - 111
Cited by:  Papers (25)
| | PDF (304 KB)

The power-law process is often used as a model for reliability growth of complex systems or reliability of repairable systems. Often goodness-of-fit tests are required to check the hypothesis that failure data came from a power-law process model. Three statistics, Kolmogorov-Smirnov, Cramer-von Mises, and Anderson-Darling, are considered for a goodness-of-fit test of a power-law process in the cas... View full abstract»

• ### Hazard-rate tolerance method for an opportunistic-replacement policy

Publication Year: 1992, Page(s):13 - 20
Cited by:  Papers (14)
| | PDF (420 KB)

A model for a system with several types of units is presented. A unit is replaced at failure or when its hazard (failure) rate exceeds limit L, whichever occurs first. When a unit is replaced because its hazard rates reaches L, all the operating units with their hazard rate falling in the interval (L-u, L) are replaced. This policy allows joint replacem...

Cited by:  Papers (68)  |  Patents (1)
| | PDF (312 KB)

Systems which have to work at or below a maximum acceptable failure rate should be maintained at predetermined points such that the failure rate does not exceed the acceptable level. As the system ages, the post-maintenance failure rate of the system drops to some newer one, unless the system has been replaced, but does not restore the system to the original state. A branching algorithm with effec... View full abstract»
