Application in Automotive Brake Assembly Process (ABAP)
Client: Automotive Manufacturer
Challenge: Manual and semi-automated operations in ABAP lead to human errors (misalignment, uneven torque), causing noise, braking instability, and rework.
Solution: Implemented a hierarchical PSF framework and quantified PSF importance using Trapezoidal Fuzzy Number Entropy Method to identify critical error sources.
Results: Identified 'Environmental' and 'Organizational' factors as most influential, laying groundwork for targeted interventions to improve human reliability and reduce quality defects.
Impact: Foundation for future human error probability modeling (BN-SLIM, Bayesian networks) and assembly-process optimization.
