Overview/PARCOM (Parts Requirements and Cost Model) Turnkey Project (OPTP)

摘要

The project consisted principally of a turnkey transfer, from CAA to the Aviation Systems Command, of the Overview and PARCOM Models, developed on a previous study (Aircraft Spares) to provide a quick reaction methodology for forecasting aircraft fleet wartime sustainability and spare parts requirements. The project also included testing of the Dyna-METRIC Model, to meet a perceived shortcoming of Overview and PARCOM--their inability to represent a partial substitution parts replacement policy. PARCOM was extended to include partial substitution and to replace Overview. Dyna-METRIC can assess fleet sustainability with part substitution, but is expected to be most useful for higher resolution (multi-echelon and indenture) analyses. Keywords include: Aircraft; Spares; Spare parts; Logistics; War reserves; Stockage requirements; Inventory management; Overview; PARCOM; Dyna-METRIC; Partial substitution.
