Application of Kanban, Work Study & Simulation to Reduce High Wip: a Case Study on Veneer Lamination Line

The objective of this book is to illustrate ways to reduce the numbers of work-in-process (WIP) at veneer lamination line using application of Kanban, work study and simulation. The main problem is the high work-in-process at hot press station. Besides that, the other problems that been identified and formulated was high rejection problem, poor production planning and scheduling and unbalanced cycle time. Different approach has been applied to overcome all of these problems. Just-In-Time (JIT) philosophy in terms of Kanban system (pull system) is the first approach to overcome the high WIP and rejection problem. Second approach is on the scheduling analysis of priority rules to overcome the poor planning and scheduling problem by comparing the existing rules of sequencing jobs by using EDD method with FCFS, SPT and LPT methods. The third approach to overcome the unbalanced cycle time is from the line balancing analysis by analysis by using the Ranked Positional Weight (RPW) method. To overcome the ineffective work motion, work study been used by using the Therbligs method. The final approach is by using the WITNESS simulation to simulate system.
