This research was conducted in response to a request by the Navy Manpower Analysis Center. The research examined the Preventive Maintenance to Corrective Maintenance Ratio (PM:CM) as part of the Ship Manpower Document (SMD) requirements development process. Established in 1968, the PM:CM ratio has never been revised. Previous research indicates that the PM:CM ratio used by NAVMAC underestimates actual CM performed on board ships. The research examined the 1:1 (electrical) and 2:1 (mechanical) ratios used to accurately forecast CM. The study analyzes effects to the SMD when actual Open Architectural Retrieval System (OARS) CM data is used. This study used one Engineering and one Combat Systems work center as a baseline. CM OARS data for the work centers was provided by NAVSEA and PM data was provided by NAVMAC. Findings indicate that across all DDG flights, the PM:CM ratio understates the amount of CM performed. The resulting ratio for electrical maintenance was1:10.9 and for mechanical maintenance 1:1.64. When CM from OARS was used to determine SMD requirements as outlined in OPNAVINST 1000.16K, it resulted in increased functional work on all flights of DDGs.
