VRPBench
收藏资源简介:
VRPBench是一个用于车辆路径问题(VRP)的基准工具,由巴西坎皮纳斯大学技术学院的研究团队开发。该数据集基于Artur Nogueira市的实际邮件配送情况,通过提取城市数字地图中的加权图来创建具有挑战性的VRP基准。每个实例模拟了一天的邮件配送,包含数百到数千个配送点,适用于优化算法的比较和验证。数据集的创建过程涉及将城市街道抽象为加权无向图,其中街道拐角和配送点作为顶点,街道作为边,边的权重与行驶时间成正比。VRPBench旨在解决实际的物流配送问题,优化路径长度和配送效率,是VRP研究领域的一个重要资源。
VRPBench is a benchmark tool for the Vehicle Routing Problem (VRP), developed by a research team from the School of Technology, University of Campinas, Brazil. This dataset is built upon real-world mail delivery scenarios in the city of Artur Nogueira, and creates challenging VRP benchmarks by extracting weighted graphs from urban digital maps. Each instance simulates a full day of mail delivery operations, encompassing hundreds to thousands of delivery points, and is suitable for the comparison and validation of optimization algorithms. The dataset creation process involves abstracting urban streets into weighted undirected graphs, where street intersections and delivery points act as vertices, streets as edges, and the edge weights are proportional to travel time. VRPBench aims to solve real-world logistics distribution problems, optimize route lengths and delivery efficiency, and stands as an important resource in the field of VRP research.
