Randomized trial optimizes cold chain delivery with electric vehicles, suggesting efficiency improvements in logistics.

This research aims to minimize costs in electric refrigerated vehicle routing using a mixed charging mode.
Developed an optimization model addressing vehicle load and battery capacity, customer time windows, and cargo damage costs.
Proposed an improved Grey Wolf Optimizer (IGWO) algorithm to solve the NP-hard routing problem.
Conducted comparisons of IGWO with GA, GWO, and ALNS across modified Solomon benchmark instances.
The IGWO demonstrated enhanced solution quality and convergence performance compared to other algorithms.
Experimental results indicated the model effectively captures characteristics of electric refrigerated distribution.
Mean and standard deviation results show IGWO's competitive solution quality and robustness.
