Problems solved by technology

The current VRP research aims to minimize the total distance, and will not travel at a time-varying speed, while the speed of a vehicle in a real environment is almost impossible to be constant, and will be affected by various factors such as time factors and road factors
[0003] Therefore, it is difficult to achieve the best results in practical applications if the VRP research is conducted with the minimum total distance without considering the time-varying velocity

no. 1 approach

[0034] In the field of Vehicle Routing Problem (VRP), there are some studies aimed at reducing carbon emissions, and these studies usually assume that the speed of vehicles is constant. In fact, the carbon emission of a vehicle is greatly affected by its speed, and the speed of a vehicle in a real environment is almost impossible to be constant. On the one hand, the speed of vehicles is affected by time factors. For example, in urban life, due to traffic congestion during peak hours, vehicles cannot travel at normal speeds, and the stagnation of vehicles leads to an increase in carbon emissions. On the other hand, road grades (e.g., urban roads, elevated roads) also greatly affect vehicle travel speeds. Therefore, the speed of the vehicle generally changes with time, and there should be a strong correlation between the carbon emissions of the vehicle and the vehicle speed.

[0035]In the first embodiment of the present invention, by introducing the time-varying speed of the v...

[0122] Step S202, using the outer approximate linearization method to linearize the carbon emissions planning model to obtain a mixed integer linear programming model;

[0123] Step S203, when large-scale problems are involved, use the hybrid particle swarm optimization algorithm to solve the mixed integer linear programming model to obtain the minimum value of the carbon emission function;

[0124] Step S204, plan the driving speed and road route of the vehicle according ...

no. 3 approach

[0155] The third embodiment of the present invention relates to a vehicle carbon emission planning device, such as Figure 3-1 shown, including:

[0156] The model building module 301 is used to set up the carbon emissions planning model of the vehicle, and the carbon emissions planning model includes a carbon emissions function and several constraints;

[0159] Among them, the parameters of the carbon emission function include time-varying speed, which refers to the instantaneous speed of the vehicle that changes with time.

[0160] In this embodiment, the carbon emission planning model is a nonlinear mixed integer programming model; the model solving module 302 specifical...
