A Simulation Model for dynamically adjusting the number of Kanbans in Generalized Kanban Systems

Kanban control systems used to optimize inventory levels just in time (JIT) production systems. Evaluation of kanban systems are based on flow control principles and it plays a very important role in production systems. This article presents a new dynamic card control methodology in order to keep a high level of performance measures. The main advantage of the proposed method is easy to adjust parameters. A simulation model for generalized kanban control system with dynamic adjustment of kanban size is proposed. Simulation experiments designed to test the effect of kanban sizes on performance measures such as total production time and amount of work in process, as well. The results of the simulation model indicate the improvement in production rate and reduction of backlog demand by automatic and dynamic adjustment of kanban size.
