Supplementary data for multi-objective decision support for cost–carbon–process-hour trade-offs in prefabricated cold-formed steel residential framing

This Zenodo record contains supplementary material and processed data supporting the manuscript titled “Multi-objective decision support for cost–carbon–process-hour trade-offs in prefabricated cold-formed steel residential framing: A single-case study from New Zealand”. The archive includes the response-model formulation, coefficient audit, uncertainty-range rationale, optimisation settings, convergence diagnostics, grid-reference comparison, OC-fixed diagnostic, sensitivity outputs, processed case-study inputs, final nondominated archive, representative Pareto solutions, Monte Carlo robustness outputs, TOPSIS ranking outputs and dashboard export fields. The interactive dashboard is provided as a visualisation and shortlisting interface for the released processed outputs. The full Python analysis code is not publicly released because it contains project-specific data-processing, calibration and internal workflow scripts associated with the case-study framing package. Project-identifying and commercially sensitive information has been removed where required.
