With the failure of MRP to offer enhanced system performance, the shift has focused to Just-in-time production systems which are driven by customer demand.Hence, the jobs are “pulled through the system” with linkage between stages in the production process (Deleersnyder, et al., 1989).
With the failure of MRP to offer enhanced system performance, the shift has focused to Just-in-time production systems which are driven by customer demand Hence, the jobs are “pulled through the system” with linkage between stages in the production process (Deleersnyder, et al., 1989). The Japanese system of Kanban is required in order to physically implement the pull production system. Kanban is often used in conjunction with Just-in-Time production whereby the right quantity must be manufactured at the appropriate level and at the right time. Literally translated as “a card”, the Kanban signal, which is generated through the master production schedule (MPS) or customer demand, triggers JIT as it works its way backwards through each work centre. Generally, a Kanban is tied to each container of work-in-progress (WIP) which contains specifications pertaining to that WIP such as the lot size, card number, due date etc. Research has demonstrated various benefits associated with the use of Kanban. JIT allows most companies to achieve the benefits of shorter lead times, enhanced quality and low inventory buffer (Cimorelli, 2013). However, choosing the Kanban size often requires tradeoffs. For instance, a large size of Kanban will often result in higher level of stock albeit with a shorter lead time and less time for setting up machines frequently. Furthermore, Kanban acts as a means of communication from usage points to the prior operation as well as serve the purpose of visual signage (Wang, 2011). ...
