| Abstract:In order to assist the logistics industry in achieving its goal of peak carbon dioxide emissions and carbon neutrality, construction must be facilitated, and a green logistics industry must be rapidly established and developed. Firstly, a multi-trip green vehicle path optimization model with soft time window constraints is constructed by comprehensively considering the factors of fuel consumption, carbon emission, manpower, vehicles, and user experience. Subsequently, the PinSAGE graph network, TRPO, and GAE methods are considered collectively to enhance the deep reinforcement learning optimization algorithm of Actor-Critic. Ultimately, the Actor-Critic algorithm is employed to address the model for the green multi-trip vehicle path scheme.Experimental evidence indicates that the solution method proposed in the paper is an effective means of planning green vehicle routes, which in turn has the potential to significantly reduce logistics costs and realise the dual optimisation of economic and environmental benefits for logistics enterprises. |
