Abstract

A Instantaneous availability modelling method for repair system was introduced. The empirical modeling method was used to the reliability function, and the life distribution selection method was proposed. Then, under the assumption that the maintainability was decreasing with the calendar time, the Fourier function was chosen for the basic fitting functions. Under the original definition of availability for the system, the availability modeling method was proposed. Finally, a case example for the method was given, and the result showed that the method was convenient for availability evaluation.
