Abstract: This paper proposes a closed-loop equipment support system which is consisted of a spare parts warehouse and a repair workshop based on Performance-Based Logistics （PBL） pattern. The steady-state probability distributions of spare part inventory level and the availability are derived. The decision-making model for the equipment user and the service provider is established and a Quantum Genetic Algorithm （QGA） is proposed. The policies on after-sale support for equipment repairable parts are discussed by numerical experiments.
