Optimal Policies for Supply Strategies under Uncertainties

Abstract

We consider a single-stage firm, facing the choice of make-to-stock (MTS) and make-to-order (MTO) supply strategy. For a benchmark system with a Poisson demand process and exponential processing times, we prove that a utilization-threshold policy is optimal; i.e., if the utilization is above the threshold, the MTS strategy is optimal, and otherwise, the MTO strategy is optimal. When the demand process is not Poisson, the optimal policy is more involved but is still a threshold type, but the threshold depends on both the arrival variability and utilization. When the service time becomes general, the optimal policy is affected by supply variability, utilization, the waiting-time distribution, and cost parameters. Further, analytical and numerical results show that when demand uncertainty is high, the firm should follow the MTO strategy to be responsive to market while when the supply uncertainty is high, the firm should follow the MTS strategy to hedge the risk of breakdown and supply disruption.
