Cooperative trucks and drones for rural last-mile delivery with steep roads

The following instances are originally presented in the paper <em>Cooperative trucks and drones for rural last-mile delivery with steep roads</em>. The data includes 96 instances corresponding to different scales and scenarios. Each instance is named "<em>n</em>. <em>d</em>. <em>m</em>. <em>h</em>", where <em>n</em> is the number of customers, <em>d</em> represents the dimension of the grid, <em>m</em> is the generic name of the scenarios with different coordinates and demands, and <em>h</em> refers to the generic name of the altitude scenarios. The first column of each instance file indicates <em>Coordinate X</em> of each customer. The second and third columns are <em>Coordinate Y</em> and <em>Demand, </em>respectively<em>. </em>The last column is <em>Altitude</em>. Finally, there is an extra file, named <strong>Supplemental online material,</strong> which provides the following appendices： Appendix A: Provides calculations about the main parameters of drone energy consumption. Appendix B: Discusses the differences between the proposed problem with GVRPD and GVRP-SR. Appendix C: Provides the detailed principles for generating benchmark instances. Appendix D: Provides information about the value of the parameters in the main configuration of the problem.

下述数据集实例最初发表于论文《针对陡坡道路乡村末端配送的协作卡车与无人机》（Cooperative trucks and drones for rural last-mile delivery with steep roads）。该数据集共包含96个对应不同规模与场景的实例。每个实例的命名格式为*n.d.m.h*，其中*n*为客户总数，*d*代表配送网格的维度，*m*为带有不同坐标与客户需求的场景通用标识，*h*为海拔场景的通用标识。每个实例文件的第一列为各客户的X坐标（Coordinate X），第二列与第三列依次为Y坐标（Coordinate Y）与客户需求（Demand），最后一列为海拔高度（Altitude）。此外，数据集附带一个名为**补充在线材料（Supplemental online material）**的附加文件，其中包含以下附录：附录A：给出无人机能耗核心参数的计算过程；附录B：探讨本文所提出的问题与GVRPD、GVRP-SR的差异；附录C：给出基准测试实例生成的详细原理；附录D：给出问题主要配置方案下的参数取值信息。
