A Kanban system is a visual way to implement a pull system. The basis of the system are the so-called Kanban cards, which basically are work authorization forms. Only if such a Kanban card is

The previous models all assumed, that customers would wait as long as it takes in order to get processed. In more realistic models, customers will leave the process before getting served because the waiting time

All previous contemplations were based on the idea that customers would be served in exactly the order in which they arrived. But is that an optimal procedure? The idea behind sequencing (which is also called
