<b>Title</b>: Dataset for Vehicle Routing Problem with 3D Loading Constraints (3D L-CVRP Dataset)
<b>Abstract</b>: This dataset provides comprehensive data support for research on the Vehicle Routing Problem with 3D Loading Constraints (3D L-CVRP). The data includes basic datasets starting with "E" from the CVRPLIB library, as well as real-world case data (case_data). The case data contains information such as station code, station coordinates, commodity code, and station cargo demand (unit: kg). In addition, the dataset also includes six experimental data files (experimental_data_1-6), whose structure is consistent with the case data. The commodity information table (commodity_information) provides detailed information including commodity code, length, width, height (unit: millimeter) and volume (unit: cubic centimeter). This dataset is applicable to research in fields such as 3D loading optimization, vehicle routing planning and related disciplines.
