碩士 / 國立勤益技術學院 / 工業工程與管理系 / 93 / In order to develop Taiwan into a global logistics
management center, the government has established two
export process zones located in Taichung port and Taichung
Tan-Ze area. Since the famous TFT-LCD company AUO built up
factory in Taichung Science Park, several upstream and
downstream TFT-LCD- related suppliers (i.e., white light
source; Polarizer; Circuit Plate; Color Filter; Liquid
Crystal Solution; Viewing Side; etc.,) have also
established new plants near AU Optronics Corp in the three
districts above. The specific supply chain base of liquid
crystal display industry supply chain was already
established in the Taichung area.
Since Taiwan became a member of WTO, the TFT-LCD industry
has been faced with serious global competition.
Nevertheless, many TFT-LCD companies are still operated
with a market-forecasting-oriented planning process called
Push System. It has resulted in unbalanced production and
shipment level associated with heavy excessive inventory
across the supply chain. To reduce the total inventory
amount, it is better to implement a shared information
function across the TFT-LCD supply chain. Then, Taiwan’s
TFT-LCD industry competence can be strengthened.
The research program was cooperated with a local TFT-LCD
industry. We had analyzed the traditional supply chain
process for the specific TFT-LCD industry. Based on the
supply chain operation reference model (SCOR), TFT-LCD
supply chain process was modeled with a Java-based
simulation system named Anylogic. The automated inventory
replenishment policies : (s, S) and (s, Q), were associated
with key performance indicators (KPIs) (e.g., total
inventory cost, ordering cost) which had been implemented
in the simulation model. The traditional TFT-LCD supply
chain was modeled and analyzed by KPIs. We also had
designed an alternative simulation model which was
characterized by the Demand-Driven Supply Networks (DDSN)
structure called Pull System.
The Push and Pull systems have been simulated many times.
We find that the inventory quantity of Push system is
greater than that of Pull system. The integrated inventory
cost of Push system is two to three times greater than that
of Pull system. We also find that the ordering cost
associated with (s, S) inventory replenishment policy is
less than that associated with (s, Q). Finally, we conclude
that the DDSN-enabled Pull system for TFT-LCD industry
supply chain can achieve a greater performance
