PRAISE: A PC-based reliability evaluator

Abstract

The US Naval Air Development Center has developed the parametric reliability, availability, integrated system evaluator (PRAISE). PRAISE is a generalized, user-friendly microcomputer-based mathematical model with graphics capability, allowing the user to perform reliability/availability evaluations and design tradeoff analyses for highly complex redundant systems. Inherently, the calculations of reliability, maintainability, and availability (RMA) for highly redundant systems require the solution of complex equations and/or sets of equations. Additionally, personnel performing these calculations must be extremely knowledgeable in RMA concepts to properly select the appropriate equations for the calculations needed. Typically, these equations must be derived/researched whenever needed. This generalized PC-based math model permits the performance of these calculations quickly and accurately by personnel not highly experienced in complex R&M methodologies.<>
