Model Selection for the Reliability of a Machine

Model selection is an important factor in the non-homogeneous poisson process used to determine the reliability of a machine. In this article, the most commonly used power law model and log-linear model in the non-homogeneous poisson process are compared. For the reliability of a bank's ATM machine, the reliability values and expected failure numbers were calculated according to both models by using the times between failures. The obtained values were compared and it was decided which model was the better choice.
