Analysis of local decision rules in a dual-kanban flow shop

An extension of Berkley and Kiran's 1991 study on the effects of four kanban policies, which include number of kanbans and status of waiting withdrawal kanbans, showed the impact of those policies in four performance criteria such as average customer wait-time and total inventory. The result is a good tool for managers in evaluating system performance in an improvement process where these kanban variables are present. The data regarding withdrawal kanbans in sequencing decisions leads to the simultaneous improvement in customer wait time and total inventory.
