Reducing Work-In-Process (WIP) in manufacturing systems is associated with advantages such as predictable throughput times and increased manageability. To achieve this, an abundance of WIP control methods have been developed, such as CONWIP and Kanban for repetitive manufacturing, and LUMS COR and POLCA for high-variety manufacturing. These methods take three types of control decisions: release (entry to the manufacturing system), authorization (entry to a work centre) and dispatching (order selection at a work centre). All existing WIP control methods are hierarchical by first deciding on release and authorization, before making dispatching decisions and doing so based on local (work centre) information.
Smart industry developments have led to more data (via sensors) becoming available real-time at the system level, and in that light one can question the use of local information in a hierarchical setup. Correspondingly, in this seminar, I propose and discuss two new methods. The first does not consider release and authorization decisions, but does take into consideration the global system state when dispatching. The second method considers all decisions simultaneously based on the global system state. I present simulation results, showing the new methods considerably outperform existing ones in terms of reduced WIP and improved delivery performance measures.
