Embodiment
[0036] Embodiment: A method for dynamic vehicle route optimization of fresh agricultural products in sub-regions and multi-stages, comprising the following steps,
[0037] S1) Acquire data, including the total number of vehicles, vehicle capacity, fixed vehicle speed, maximum driving distance of vehicles, initial freshness value and arrival freshness value of each product that do not meet the required freshness value or the unit penalty caused by the freshness threshold Cost and order data, where the order data includes initial order data, new order data and the location of the order site. For the multi-regional and multi-stage dynamic vehicle route optimization problem for fresh agricultural products, it can be defined as follows: to ensure that the demand of each order is met and not exceed the maximum load capacity and maximum driving distance of the delivery vehicle, considering the vehicle’s violation of the time window limit and freshness In the case of limiting the addi...
