SYSTEM FOR ANALYZING QUALITY DEFECT IN MANUFACTURING PROCESS

摘要

PROBLEM TO BE SOLVED: To provide a system for analyzing quality defect in a manufacturing process, that can compare a defective portion in a selling store with a checked result portion in a factory by a development to calculate a correlation ratio, and quickly specify the cause of the failure in a manufacturing process based on judgment from the correlation ratio. ;SOLUTION: A product defective site 85 is displayed at a development 84 based on coordinate data extracted from quality associated data being data related with any defective portion in a selling store by development contrast display software 34 of a quality failure analyzing CPU 30, and a checked result portion 86 is displayed at the same development 84 based on the coordinate data extracted from checked result data being data related with the portion associated with the check in the factory. Also, a correlation ratio 88 is calculated by using the coordinate data, and the factor of the cause of the failure is extracted based on the correlation ratio, and the cause of the failure is surveyed from the extracted factor by failure cause surveying software 39.;COPYRIGHT: (C)2003,JPO
