Impact of the Transport Activities within a Closed-loop Supply Chain: Study of theLost Profit Risk

This paper studies manufacturing/remanufacturing system with transportations activities. The proposed supply chain is composed of two parallel machines, new products store, purchasing store, transport vehicles, recovery store at the remanufacturing process and recovery store at market. The objective is to determine the optimal system design and then to study the lost profit risk related to the transport delay. Thanks to discrete flow model, the system is described and mathematical model is developed. The proposed model is then simulated and the lost profit risk is studied. Numerical results are presented to discuss the lost profit risk.
