This paper presents a case study of z L-transform method application to calculation of availability for complex aging refrigeration system. The system and its components can have different performance levels ranging from perfect functioning to complete failure and, so it is treated as a multi-state system. Straightforward Markov method applied to solve the(More)
We consider data processing for a Nonhomogeneous Poisson process (NHPP) with Log-linear and Power-law intensity functions. Parameter estimation is carried out by the maximum likelihood method. For the case of the known intensity function, testing the hypothesis that the given sample path is a realization of NHPP, can be accomplished using the fact, that(More)
