This thesis provides a statistical and economic assessment tool for the analysis of failure characteristics of equipment whose failure data are reported in the U.S. Navy's Maintenance and Material Management (3M) system. The software accompanying this thesis is written in a programming language compatible with the Microsoft Excel (spreadsheet) operating environment. With the software, the reliability engineer will have the ability to manipulate and analyze 3M data directly using customized menus and point and click mouse operations. Specifically, the software: transforms the complex 3M database into matrices of failure/inter-failure times and their associated costs; estimates the parameters of a discrete time nonhomogeneous Poisson process model having a geometric rate function; and employs the model to derive an optimal maximum replacement interval based on costs and expected number of failures. The software can be used to do sensitivity analysis to help the analyst examine the consequences of different replacement intervals or spare part provisioning and preventive maintenance policies.
