Lot release planning for customer oriented manufacturing

Planning in semiconductor plants tries to optimize throughput and minimize WIP. On the other hand, there is a strong need for high delivery performance. Meeting the promised due dates becomes more and more a hard requirement. Therefore, we developed a planning methodology that tries to balance the needs of the fab and the needs of the markets. A rought, capacity basket model based approach for CTP and a linked simulation model for lot release planning based on the results of rough planning
