Research question

How does retaining calibration uncertainty change maintenance demand under the same exposure and intervention rules?

Method & evidence

A log-space diffusion calibration supplies residual dispersion from 36 real test observations. The study propagates that dispersion through 15,000 Fickian simulations per case and applies explicit maintenance and life-cycle scenarios.

Finding & status

Expected maintenance demand increases by approximately 20–40% relative to deterministic estimates in the paper’s reference scenarios.

Conditions of interpretation

Reference OPC dataset, specified exposure and planning horizons, and initiation-triggered maintenance policies. These scenario results require site-specific calibration for an asset application.
