PRODUCTION DATA ANALYSIS METHOD AND PRODUCTION DATA ANALYSIS DEVICE

摘要

PPROBLEM TO BE SOLVED: To heighten analysis accuracy of production data having a loss value. PSOLUTION: An explanatory variable of an analysis target is selected (Figure 3, S11). Production data acquired from each process are divided into a set having the loss value and a set having no loss value (S13). An evaluation value for evaluating influence imparted to an object variable by the explanatory variable is calculated from the production data of the set having the loss value and the set having no loss value (S14). The calculated evaluation value is collated with a decision criterion to analyze the production data (S16). PCOPYRIGHT: (C)2007,JPO&INPIT
