Performance-based logistics (PBL) is becoming a dominant support strategy for military equipment systems. This paper sets up a closed-loop support system which consisted of a spare parts warehouse and a repair workshop. Firstly, we set up the transition balance equations for the inventory level state. Then, the steady-state probability distribution of spare part inventory level is derived. Then, we conduct several experiments to investigate sensitivities of system’s parameters. Our research will help to improving the support level for our army.
