The model visualises the system for evacuation of fruit from oil palm plantations to mills for processing. Mills are marked in blue, and the trucks collecting fruit from plantations are shown as red dots.

Initially truck routes are optimised solely on the yield from different plantations (shades of green), to collect the most fruit possible. Then we change to optimising to collect from the most sustainable sources and avoiding plantations with a high risk of deforestation (shades of red).
