摘要:

铁路物流园区内部短驳运输面临效率瓶颈问题,无人机为突破此瓶颈提供了新的解决途径。然而,无人机引入后引发了复杂的空地协同调度难题。针对此问题,开展了考虑多重时空约束的无人机协同调度优化研究。首先,分析了任务分配、无人机能力、节点容量及空域安全等核心约束;其次,构建了以最小化最大完工时间为目标的混合整数规划模型;进而,设计了一种融合动态贪婪初始化策略与改进遗传算法的两阶段启发式算法。仿真结果表明,该算法能显著缩短任务周转时间并提高无人机利用率,为园区智能调度提供了决策依据。

Abstract:

The internal short-distance transportation in railway logistics parks faces efficiency bottlenecks, and drones offer a new solution to break this bottleneck. However, the introduction of drones creates complex air-ground collaborative scheduling challenges. Focusing on this issue, this paper investigates the collaborative scheduling optimization of drones under multiple spatiotemporal constraints. Firstly, this paper systematically analyzes core constraints including task assignment, drone load and endurance, node capacity, and airspace safety. Secondly, this paper establishes a mixed integer programming model aimed at minimizing the maximum completion time. Furthermore, this paper designs a two-stage heuristic algorithm integrating greedy initialization and improved genetic algorithm. Simulation results demonstrate that the proposed algorithm significantly reduces average task turnaround time and improves drone utilization rates, providing a quantitative decision-making basis for intelligent park scheduling.
