ASSESSING SYSTEM AVAILABILITY USING THE GRAPHICAL EVALUATION AND REVIEW TECHNIQUE SIMULATION (GERTS) APPROACH.
Abstract
Reliability, maintainability, and availability are three measures of system effectiveness. These measures may be usedto assess effectiveness for currently operating systems or to predict effectiveness for planned systems. The various agencies responsible for the design, support, and actual operation or use phase of a system's life cycle have differing interests with regard to effectiveness measures. The design phase, which is essentially the responsibility of an engineering or technically oriented agency, is generally more concerned with the reliability or quality of the system. System support agencies, such as maintenance and supply (logistics) oriented agencies, are more concerned with the maintainability measure of system effectiveness. The actual operator or user of the system is interested in the productive capability or useability of the system. This particular measure, which is known as the availability of the system, is dependent on the reliability and maintainability measures. The operating or using activity for the system is generally also the acquisition agency.
