The study described herein was undertaken with the objective of determining how system effectiveness is affected by its environment. In meeting this objective, quantitative values were developed for those environmental factors that were found in our study to affect system unavailability. Systems and subsystems that were selected for study were chosen for their relative position in regard to the state of the art. Many were of recent development employing state-of-the-art advances in design and construction. Other constraints used in system and subsystem selection were that they provided appropriate environmental mixtures such as physical location (Desert, Tropics, Arctic, etc.) and present particular maintenance and operational philosophies. A Random Balance Statistical Technique was used to analyze the data and positively identify, based on the data sample, environments such as temperature, ambient high, and artificial environment, air conditioning that contribute to system unavailability for Radar, Communication, and Electronic Data Processing systems. The information on environments identified and quantified herein is intended for use by designers and system planners so that they may apply safeguards to systems and subsystems to circumvent those environments found to degrade system performance.
