摘要:

在植保作业中多车辆协同多无人机能突破续航等限制,可大幅提高作业效率.针对多车辆-多植保无人机作业路径规划求解难度大等问题,建立一种多车辆协同多植保无人机路径优化模型,并以无人机最大作业时间最小化为优化目标.同时,提出改进的simulated annealing‐Lin Kernighan Helsgaun (SA-LKH)算法求解该模型.所提算法融合K-均值聚类法和凸包插入法生成初始解,利用LKH算法优化每组无人机和车辆路径.此外,构建有向扰动算子,通过扰动每次迭代过程中作业时间最大和最小的路径来实现算法的快速收敛.5种不同规模算例的结果表明,所提算法在求解质量和效率上均优于对比算法.

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.
