The agri-food supply chain requires accurate forecasting of its production performance since failure affects a vital population need. Maize, rice, and wheat are the three primary cereals consumed globally. However, a key distinction in the industrial processing of maize compared to rice and wheat is dry and wet milling. Dry milling of maize yields primary products such as semolina and various flours, while wet milling primarily generates starch, gluten, and feed. Wet maize is highly vulnerable to fungal growth and insect pests. Therefore, it is necessary to minimise storage duration before processing. Ideally, grains should be incorporated into the processing chain immediately after harvesting, so scheduling harvest activities is vital for achieving optimal results.
