摘要:

无人机(UAV)是一种可以完全自主飞行而无需人为干预的飞机。无人机可以使用的最有用和最有前途的领域之一是自然灾害管理。在本文中,我们专注于一个紧急情况下,并建议使用一个舰队的无人机,帮助救援队个性化的人需要帮助的受影响地区。我们将这种情况建模为一个原始的图论问题,称为总完成时间最小化的多站点多行程车辆路径问题(MDMT-VRP-TCT);我们经历了一些已经在文献中研究过的问题,这些问题在某种程度上看起来与它相似并突出了差异,提出了一个数学公式来解决我们的问题作为MILP,设计了一个数学框架来快速解决大型实例,并通过实验测试其性能。除了建议的应用程序,我们的解决方案的作品在任何情况下,必须解决一个多车场多行程车辆路径问题。

英文摘要:

Unmanned aerial vehicles (UAVs) are aircraft whose flights can be fully autonomous without any provision for human intervention. One of the most useful and promising domains where UAVs can be employed is natural disaster management. In this paper, we focus on an emergency scenario and propose the use of a fleet of UAVs that help rescue teams to individuate people needing help inside an affected area. We model this situation as an original graph theoretical problem called Multi-Depot Multi-Trip Vehicle Routing Problem with Total Completion Times minimization (MDMT-VRP-TCT); we go through some problems already studied in the literature that appear somehow similar to it and highlight the differences, propose a mathematical formulation for our problem as a MILP, design a matheuristic framework to quickly solve large instances, and experimentally test its performance. Beyond the proposed application, our solution works in any case in which a multi-depot multi-trip vehicle routing problem must be solved.
