Levitt and Abraham [11] conclude that implementation of JIT in semiconductor manufacturing has lead to
reduction of manufacturing time and excellent regulating of manufacturing method with different bottleneck
time. However, Stump and Badurdeen [9] had argued that JIT is applicable for industries with less customization
module and high standardization. Only a few ideas are practical to apply in mass customization and low
standardization area for example kaizen and visual housekeeping management (5S).
Pull system is used to manage inventory and control flow of material. It is driven from downstream needs which
trigger upstream production. At the manufacturing area, the pull system would be able to reduce inventory level
by replenishing parts that are consumed by the customer. The authorization of production begins when a part is
pulled from the inventory area [1, 2].
