Framework for a closed control loop between supply chain segments and production line

Current production planning systems are not designed to adapt to changes in supply chain networks, like unexpected change in customer's demand, automatically and in real-time. Semiconductor manufacturers are forced to react on those events with non-automated procedures, large inventories and long lead times. Therefore, decisions are unnecessarily delayed and corrective actions in semiconductor wafer processing, often called front-end, may take place too late. Thereupon, we identified the need for a technical solution to automate and accelerate decision making in complex production environments, considering multiple aspects like product mix, time-coupling and on time delivery.
