Abstract

Value stream mapping (VSM) plays an important role in the journey toward lean manufacturing by identifying the starting point (current state) to destination (vision). When graphically depicting what is currently happening on the floor, the work-in-process (WIP) inventory is always found on an unbalanced assembly line. To reduce WIP, an operational model is built for minimizing the total cost on the condition that takt time and cycle time are given. Numerical examples are presented to illustrate the problems of determining the optimal batch size and classifying the parts into bin system when using kanban operation.
