Companies are faced with the challenge of making their factories smart and efficient: less costs and time while at the same time increasing output. But how can production planning support these challenges? What adjustments do you have to make to achieve this? And how can intelligent detailed planning systems provide useful support? Production planning must take into account the target criteria of minimizing setup times and throughput times, optimizing personnel, production costs and machine utilization, and adherence to schedules when optimizing production, while at the same time also keeping track of and controlling all planning-relevant resources and restrictions in production. To make matters worse, optimization goals often compete with each other. Conventional planning methods such as Excel are no longer capable of handling such a complex task. Intelligent planning solutions such as S/4HANA provide a remedy. They enable smooth order throughput, short delivery times and cost optimization. The hallmarks of the smart and efficient factory of tomorrow.
