Abstract: Due to the time-varying and uncertain market demand, it is extremely difficult to select the control strategy in the production and inventory control problem. In the production inventory problem, because of the time-varying and uncertain market demand, it is difficult to select the control strategy based on the accurate theoretical model. Active disturbances rejection controller(ADRC) is a model-independent controller which has a good robustness and adaptability for the controlled systems with non-linearity, long time delay, and high uncertainty. Based on a classical inventory model, this paper investigates production strategies in different market environments based on ADRC. The results indicate that when the sales function is a deterministic one, the production control strategies given by ADRC are in good agreement with the optimal solutions. When there exist uncertainty disturbances, ADRC can still give satisfactory production strategies according to the errors between predictive value and the actual value. ADRC is more operable and controllable in solving actual inventory control, which can be a new and powerful tool for uncertain optimal control problems in the field of economic management.
