Moreover, the demand uncertainty is not only propagated but also magnified over the network and causes a chain effect on the planning quality of the entire supply chain. Semiconductor manufacturing network is one of the most complicated demand-supply networks and thus suffers greatly from the untrustworthy demand information. In the second year of this project, the effect on the overall equipment effectiveness (OEE) has been explored. The effects of demand grouping for equipment capacity allocation are then modeled mathematically. The model is aimed to help practitioners comprehend how demand plans work together with capacity allocation to affect the OEE. The third year of this project will focus on optimization of capacity allocation. The goal is to find optimum capacity allocation for demand groups to minimize the required equipment capacity or equivalently maximize the OEE subject to uncertain demand signals. Various combinatorial optimization algorithms, such as Greedy Algorithm, Genetic Algorithms, etc., will be investigated. Effective optimization methodologies are then suggested and tested using actual semiconductor demand and manufacturing data. |
