The Finnish dairy cooperative Valio has held a hackathon with the aim of keeping the milk supply from dairy farms as constant as possible all year round. The hackathon was won by the Swedish Elvenite AB. Elvenite proposed a pilot based on a dataset collected from a representative sample of dairy farms featuring high and low seasonality. With the comprehensive data analysis and comparison of farms with low and high seasonality, it can be understand what solutions would be the most effective. Equalizing the seasonal variation in milk production would make a dairy’s production planning more efficient. Constant production levels enable leaner and more efficient operations in the entire production chain. This would improve cost control and contribute also to a smaller footprint.
