The Production Planning Model of Giga-Fab for Semiconductor Fabrication

In this research, a model of production planning among different phases is developed. Although every phase at same giga-fab should be regarded as the similar. However, due to the different installation time, technology level and capacity allocation, the production capability of each phase will be distinguishing. Therefore, the major purpose of the production planning model is to develop a feasible and easy used algorithm to fully utilize the capacity of each phase under constraints. The concept of DBR scheduling is applied in this model to fulfill the major target. Furthermore, the notion of Technology Turn Rate (TR) is used to calculate the required date of capacity constraint resorce (CCR). Based on the prefercnce phase of products and the status of CCR, the release phase and date of each order can be well arranged.
