Abstract:

Multi-vehicle collaboration with multi-agricultural UAV operation can overcome limitations such as endurance and greatly improve efficiency. To address challenges in path planning for collaborative operations involving multi-vehicles and multi-agricultural UAVs, a path optimization model is constructed with the objective of minimizing the maximum operation time of UAVs. The improved simulated annealing-Lin Kernighan Helsgaun (SA-LKH) algorithm is proposed to solve the model. The proposed method combines K-means and convex hull methods to generate the initial solutions, and uses the LKH algorithm to optimize the paths of each group of UAVs and vehicles. Additionally, a directed perturbation operator is constructed to achieve rapid convergence of the algorithm by perturbing the paths with the maximum and minimum operation times during each iteration. The results of five different scale examples show that the proposed algorithm is superior to the comparative algorithm in terms of solution quality and efficiency.
