Development of a Mathematica Tool for Implementation of Prognostics Based on Life History

Abstract

In order to increase mission reliability and reduce the logistics footprint, considerable interest is now being focused on the implementation of prognostics. One approach to prognostics is to track usage in terms of miles, hours or cycles, and generate replacement-before-failure rules for components subject to aging whenever the system is preparing to enter a period during which failures must be zealously avoided (e.g., deployments or combat pulses). This report documents the development and notional application of a new tool that implements this approach. The tool, which is an extension of Mathematica, generates graphs and tables for a variety of metrics that one could use in an interactive decision-making process. Mathematica is a leading commercial software package for performing mathematics. Key chapters in this report constitute a basic set of electronic templates for applying the new tool. The tool itself is provided in the appendices.
