Abstract

In this paper, we propose an inventory control method for supply chain planning for single stage production systems under uncertain demand. The planning and scheduling model for uncertain demand situation is developed to represent actual environments for planning and scheduling where variances of future demand are gradually available as the time proceeds. In the proposed method, the amount of shipping for raw materials and safety stock for final products are determined by a stochastic approach by using demand average and variation in feedforward. The quantity of safety stock of inventory for final products is determined by incorporating feedback information from the detailed scheduling results. The effectiveness of the proposed methods is investigated from numerical simulations.
