Intelligent Control on Work-in-Progress Inventory Based on Biological Modulation Mechanism

摘要

Aiming at work-in-progress (WIP) inventory control in manufacturing system, Based on biological modulation mechanism of neuro-endocrine system (NES), a two-level intelligent controller which includes the master controller and the secondary one is presented. The master controller can adjust dynamically the given input value of the secondary one according to the real-time control error. Consequently, the controller can eliminate the control error quickly and stably. Finally, the proposed two-level controller is adopted to control a WIP inventory model, and the simulation results show that the control performance and adaptation of the proposed controller are better than that of the general PED controller.
