Abstract:
|
The Army's current maintenance policy for small arms weapons is to replace parts when they break or replace weapons determined to be unserviceable. However, if the weapon breaks during use on a combat mission, it could cost a soldier's life. To prevent this, we developed a system that uses a shot counter to keep a more accurate record of the wear on a weapon throughout its lifetime. Small units that operate independently only bring what they can carry for an operation; by knowing that a part is likely to break they can either replace the part in advance or take the spare parts likely to be needed. Following other industries, we developed a reliability model for components using the Weibull distribution. This system informs both operational and maintenance policy decision-makers.
