VEHICLE BODY PRECISION TREND MANAGEMENT SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a vehicle body precision trend management system that can implement improved quality and reduced development/management costs by enabling a quality manager to predict a sign of anomaly in vehicle body precision.

SOLUTION: The vehicle body precision trend management system includes an input device 20 and a communication part 18 for inputting a plurality of measured values measured in inspections made in various processes of vehicle body manufacture in association with measuring time on a measuring region basis, and a measured value database 56 for saving the input measured value group for each measuring region in time series. The system includes a processing device 10 for statistically processing the measured value group for each measuring region to calculate a mean value and a standard deviation per predetermined unit time or a mean value and maximum and minimum values of the measured values per predetermined unit time. The system includes a display 30 for graphing the statistical processing results in time series and outputting the graph and management values (standard values) of the measuring region.
