An improved simulation model for cannibalization policy performance comparisons in a complex maintenance system
Abstract
A model of a two-echelon (bases and a depot), two-indenture (machines have components which may have modules) maintenance system with spares, repair, cannibalization, preven tive maintenance, and two classes of manpower constraints is presented. A base is modeled with a SLAM II combined net work and discrete event simulation, while other bases and a depot are incorporated analytically. Although designed primarily for the study of cannibalization decisions, the model is also suitable for testing the performance of repair, spares, and other maintenance policies in complex systems, including those main taining fleets of aircraft. Applicability of the model and its new features are demonstrated by showing how previously-reported results change under different assumptions.
