Trade-offs between daily walking distance and guestroom capacity under stairwell-location constraints in small lodging facilities

This dataset contains model inputs, Python analysis code, and numerical results supporting the study “Trade-offs between daily walking distance and guestroom capacity under stairwell-location constraints in small lodging facilities”.The main dataset comprises 65,430 admissible layouts across ten hypothetical two-storey lodging models. It compares minimum mean daily walking distances for two-stairwell and three-stairwell alternatives under fixed-end, free-location, and geometric-constraint conditions. The analyses distinguish route changes for retained guestrooms from changes associated with guestroom removal and examine sensitivity to geometric and visit assumptions.The package includes layout coordinates, complete enumeration results, constraint-region tables, condition-specific comparisons, improvement decompositions, sensitivity analyses, and figure-generation code. An English README, data dictionary, CSV inventory, and manuscript-to-data mapping explain the file structure and reproduction procedures. SHA-256 checksums are provided for file-integrity verification.The ten-model enumeration was reproduced, and 392,580 metric values were checked against an independent graph-based implementation. The maximum absolute numerical discrepancy was approximately 2.27 × 10⁻¹³.These are computational results for hypothetical layouts, not observed guest trajectories. Geometric constraints are analytical comparison conditions and do not establish regulatory compliance or evacuation performance. Original third-party vessel drawings are not redistributed. Detailed supplementary texts are supplied separately with the manuscript.
