Reliability Overhaul Model

Abstract

This report discusses the initial modeling effort to develop a tool which can assist in the development of depot maintenance work requirements by determining the inherent reliability of equipment. A Monte Carlo simulation was developed. The input for the simulation includes a block diagram, a time to failure distribution or failure and suspension data for each block in the diagram, and the age of each block. The primary output of the simulation is a numerical time to failure distribution for the system. This distribution is used to generate a graph of the time to failure distribution, a histogram of the ages at which the system fails, a graph of hazard rates, a total time on test plot and a graph of the expected cost of various replacement policies if cost data is available. The algorithms and data structure used in the model are discussed as well as the potential uses of the model and its performance. Keywords: Reliability; Monte Carlo simulation; Hazard rate; Mean time to failure; Total time on test plots; Hard time replacement.
