Analyzing Availability and Readiness Using Transfer Function Models and Cross Spectral Analysis.

Abstract

Looking at the literature of reliability and life testing one does not see much on the use of the powerful methods of time series analysis. This paper shows how the methods of multivariate time series analysis can be used in a novel way to investigate the interrelationships between a series of operating (running) times and a series of maintenance (down) times of a complex system. Specifically, we apply the techniques of cross spectral analysis to help us obtain a Box-Jenkins type transfer function model for the running times and the down times of a nuclear reactor. A knowledge of the interrelationships between the running times and the down times is useful for an evaluation of maintenance policies, for replacement policy decisions, and for evaluating the availability and the readiness of complex systems.
