Determination of the number of containers, production kanbans and withdrawal kanbans; and scheduling in kanban flowshops - Part 1

In the first part of this paper, we consider a kanban-controlled flowshop and present recursive equations for time-tabling of containers in a given sequence. The flowshop is characterized by the following: a production batch of a part-type (or job) divided into kanban lots or containers; production kanbans to control the loading of containers on machines or workstations; withdrawal kanbans to regulate the movement of containers between two consecutive buffer storages; periodic material handling of containers; dual blocking mechanisms operative on workstations and material handling; and sequence-dependent set-up times of containers. Considering different types of problems, recursive equations have been developed for time-tabling of containers in a given sequence.
