scope:

The information in this manual reflects the efforts of extensive hours of research and analysis, along with the cooperation and time of numerous facilities, in order to ascertain reliability characteristics of power generation, power distribution and HVAC components. This effort was sponsored by the U.S. Army Corps of Engineers, Power Reliability Enhancement Program (PREP) in order to establish reliability, availability, and maintainability characteristics of over 200 components related to command, control, communication, computers, intelligence, surveillance and reconnaissance (C4ISR) facilities. This manual describes the data collection and summarization of all of over 200 components. Collection of the data began in October 1991 and the final report was delivered in early 1994.

Purpose

The purpose of this manual is to explain the process of how the reliability data in appendix B of this manual regarding power generation, power distribution and Heating Ventilation and Air Conditioning (HVAC) components was developed. This manual is intended to summarize the entire process of obtaining the reliability metrics of the pre-described components and what types of facilities provided the data so that the facility engineer can understand the foundation behind the reliability metrics. Upon reading this document the facility engineer should be able to make a more knowledgeable assessment for applications of the data to support government, commercial, industrial and utility installations.
