Reliability, availability, and maintainability expert system (RAMES)

A RAM modeling, analysis, and decision support system-the Reliability, Availability, and Maintainability (RAM) Expert System (RAMES)-has been developed to assist a weapon system program manager (SPM) in weapon system RAM performance analysis, master planning of RAM performance enhancements, assessment of RAM enhancement payoffs, and evaluation of mission capability, wartime operational rates, fix rates, and stock level support. These capabilities extend to five levels of indenture within the weapon system from shop replaceable units and line replaceable units to assemblies, subsystems, and systems, and to three levels of maintenance (organizational, intermediate, and depot). RAMES uses standard US Air Force maintenance data systems and compensates for certain anomalies in those systems. Wartime or extreme environment conditions can be factored into the models. In addition, RAMES is designed for integration with life cycle cost analysis and weapon system effectiveness evaluation models for a total weapon system performance analysis capability.<
