The invention relates to a durian logistics optimization method and device considering preservation constraints, and the method comprises the steps: determining a center set and a dynamic preservation
feature set of each logistics vehicle according to the distribution center of the logistics vehicles of the durian and the preservation state features of the durian loaded on each logistics vehicle; a logistics
route map is constructed by combining the introduction of a durian quality attenuation model, the information interaction training of the logistics
route map is carried out, the model optimization output is used as an optimal transportation
route map, and the
optimal combination time and the
optimal combination object of logistics combination of each logistics vehicle are determined. And the logistics combination range is limited and shrunk based on insurance constraints, so that the logistics time, the logistics cost and the logistics damage of large-scale logistics vehicles are effectively reduced, and the quality of the durian is effectively ensured.
