Cane and sugar yields within a sugar mill area vary with geographical location and climatic conditions. Delivery allocations policy and sugarcane supply management may take into account these variations of quality in order to improve sugar production and mill area profitability. In La Réunion Island, alternative supply scenarios based on quality variations were designed and simulated for Le Gol mill area. An analysis of sugarcane quality variations within the mill area was necessary to design new supply scenarios. The mill area was split into homogeneous quality zones by carrying out a statistical cluster analysis. A simulation tool, called MAGI, was then used to evaluate the impact on sugar production of supply scenarios based on two zoning levels. Different harvest windows were tested for each zone to increase sugar production. Delivery allocation took into account the mill crushing capacity and the storage and transport capacity between mill and transloading zone. Results show a gain of 2-5% sugar, depending on the zoning accuracy. (Résumé d'auteur)
