Modeling Combat Maintenance Operations

A computer model was developed to simulate helicopter maintenance operations in combat. Written in GPSS computer code, the Combat Maintenance Simulator (CMS) mathematically models a fleet of helicopters performing combat missions. Scheduled inspections, system maintenance, and repair of battle damage are performed in the course of the simulation. The user is able to specify policies with regard to deferring nonessential maintenance and repair during periods of combat emergency. Computer graphics are used to display the mission performance of the fleet under various sets of conditions. The CMS model has been used to support research aimed at reducing the maintenance workload and increasing the mission capability of Army helicopters in combat.
