Datasets for Combinatorial Auctions for Green Supplier Selection and Bundled Order Allocation

This dataset supports the study “Combinatorial Auctions for Green Supplier Selection and Bundled Order Allocation.” The paper examines how firms can select sustainable suppliers and allocate multi-product, multi-period orders through combinatorial auctions in which suppliers submit multiple, potentially overlapping bundle bids. The dataset contains input data and instance-level results for 120 heuristic-comparison instances and 27 case-study instances covering Observations 1–8. A README explains the folder structure, variables, and result files.
