Levels of Repair--Ends or Means?

R. B. Waina

Expert InsightsPublished 1970

Repair level analysis--the process of deciding whether a military item that fails should be discarded or how it should be repaired--is typically done after a system is fully defined, but it should be done during concept formulation as part of the total tradeoff structure of system performance including availability vs. cost vs. development time. This paper describes five techniques for the decision: General Dynamics' noncomputerized LOR model, Raytheon's TRIM, RCA's CO-AMP, AFLC's RGM-1, and RAND's SCAM. CO-AMP analyzes many more maintenance postures than others, does more sensitivity testing, and supplies more default variables when data are lacking. SCAM is unique in including discounting and an optimal stock leveling technique for equal availability (METRIC), and in reporting average response time for each condition.
