Nonetheless, dynamic modelling tools and feedback control are scarcely applied to WLC or other shop floor control systems. To fill this gap, this paper presents a closedloop model of WLC incorporating feedback control and shop floor inputoutput control. The bond graphs’ dynamic modelling technique is employed. The model is implemented in Simulink® and its behaviour in face of disturbances is analysed. The load of the machines and of the job pool of WLC is considered to adjust order release (input control). The capacity of each machine (output control) is altered in function of the level of its preceding buffer. The machines’ processing rates stabilize and the reference levels for the buffers are reached when a step disturbance in order entry is simulated. Also, the system responded with a maximum capacity increment of 15 % when cyclic demand is simulaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Mariboru, Fakulteta za strojništvo, Inštitut za proizvodno strojništvo
