Data and code for: Probabilistic reliability assessment and robust design of PET fiber mortar

This dataset supports the manuscript “Probabilistic reliability assessment and robust design of PET fiber mortar.” It contains the original 27-run Box–Behnken experiment and 21 author-reported historical independent mixing batches representing 12 formulations, together with documented analysis code, frozen numerical inputs and calculation outputs aligned with manuscript revision v9. The older 12-record historical table is a subset of the 21 records.

Repeated formulations F01/F02/F03 contain 3/6/3 batches. The calculations cover the reconstructed model pool and common-error screening, continuous-window numerical integration, retained interval and covariance diagnostics, source-specific external confirmation analyses, response/dose sensitivity and conditional cost comparisons. This is a transparent reconstruction where original statistical source code was unavailable; original measured values are preserved.
