It is well known that the performance of the JIT production system is optimum in a deterministic environment. However, real-world situations contain uncertainties in processing times, with which traditional JIT does not deal well. In this paper, we present a newly developed Kanban system that systematically manipulates the number of Kanbans to cope with the discrepancies introduced by the uncertainty in processing times. We illustrate that the performance of this new system is superior to the traditional JIT system in such an environment.

In this paper, we present the results of a newly developed Kanban system that systematically manipulates the number of Kanbans to cope with the interruptions introduced by machine breakdowns. We illustrate that the performance of this new system is superior to the traditional Kanban system in such an environment.

In this paper, we present a two-stage kanban control model to study a two-echelon hybrid inventory system with disposals. We then express the expected cost function for the inventory system in terms of the performance measures obtained from the analysis of the kanban model. Finally, we present the results of a series of experiments that are conducted to measure the impact of the kanban sizes on the expected total cost of the system.
