An Early Warning System for Vehicle Related Quality Data

Vehicle production audit tests, warranty claims and car control unit data are stored in a central data warehouse for data mining analysis. Neural network based part failure rate estimations, adjusted for mileage and seasonality, are used for monitoring warranty claims. Association and sequence analysis connect production audit data, car control unit data and warranty claims for an early detection of quality changes both in production state and car field usage. Calculations are performed via grid computing. 1 Data Driven Quality Management A major aspect of quality management is avoidance of quality defects. Nevertheless, 100% freedom from error in motor vehicle production and during their lifecycles cannot be achieved with these highly complex products. Therefore, a continuous quality monitoring at production time and during the lifecycle is mandatory to early address upcoming quality problems. Vehicle service centers document repair cases with standardized codes, and all reports are l...
