Statistical Tolerance Analysis for Textile Components
topic
Statistical tolerance analysis propagates the variation distributions of individual yarn, fabric, and trim component properties through garment assembly models using root sum of squares or Monte Carlo simulation, calculating the probability that assembled garment dimensions, seam strength, and appearance satisfy customer specification limits given the known variation of each contributing component.
Role
Enables rational specification setting for textile component tolerances that balances the cost of tight specifications against the risk of assembled garment non-conformance, replacing arbitrary tolerance assignment with statistically rigorous analysis of how component variation accumulates through complex garment construction and multi-supplier supply chains.
