Abstract
Semiconductor industry is becoming a service-oriented business with high technology, capital investment and fierce competition. Maximizing the capacity utilization or throughput of single production stage is not effective for the whole supply chain system. Thus, in order to improve capacity utilization, reduce total cost and make quick response to customers at the same time, there is a need to integrate each production stage in the semiconductor supply chain to achieve those targets.
In this research, we apply the Kanban concept originally used in the manufacturing system to the semiconductor supply chain system to construct an integrated multi-stage WIP control model. This model is used to decide the WIP control upper limit of each stage with the objective of minimizing total cost and the constraint of the maximal demand outsourcing proportion of the whole supply chain system. A solution methodology which combines the greedy search algorithm and global search algorithm is also developed to find the optimal set of the WIP control upper limit of each stage effectively and efficiently.
Our result shows that our proposed model can be adapted to the practices in the semiconductor supply chain. By the coordination in each production stage in the supply chain, the efficiency of the whole supply chain system can be improved in the performance matrices such as total cost, average system cycle time, the quoted lead time, and etc.. Besides, comparing with greedy search algorithm and global search algorithm, the solution methodology developed in this research is truly effective in terms of quality of our solution and calculation efficiency.
