Partial Substitution and Other Modifications to the PARCOM (Parts Requirements and Cost Model) Model (PARCOM Partial Substitution)

Abstract

This basic PARCOM methodology developed in the Aircraft Spares Study was expanded to include a partial-substitution parts replacement policy and distribution of stock over time. As with basic PARCOM, extended PARCOM relates aviation spare parts requirements and fleet capability to flying hour and availability objectives, part replacement (substitution) policies, and stockage deployment schedule, all subject to optional cost constraints. Partial substitution was defined in terms of a partition of part types into a full-sub set, within which all installed serviceable parts on NMCS aircraft are substitutable for unavailable spares, and no-sub set, within which no installed parts are substitutable for spares. The extended PARCOM was applied in several illustrative example cases, showing plausible results as substitution policy was varied. Keywords include: Aircraft, spares, spare parts, PARCOM, logistics, stockage requirements, logistics management, inventory management, helicopters, readiness.
