摘要
PURPOSE: The method for analysing the alarm factor of the monitor/control system is provided to improve an operator's management efficiency by reducing the time loss and the inconvenience, and by finding the alarm factor of the tag easily. CONSTITUTION: The system checks if the alarm related to a tag is happened(S10) and the system reads the data about the alarm occurrence factor related to the tag from the database server(S12). The system analyses if the output about the input is linear type or non-linear type(S14). If the relation of the output concerned to the input is linear type(S16), the system runs the linear regression model(S18). Otherwise, the system runs the non-linear regression model(S20). The system performs ANOVA(ANalysis Of VAriance) and creates the ANOVA table by using SSE(Error Sum Of Squares), SSR(Regression Sum Of Squares), MSR(Regression Mean Square), MSE(Error Mean Square), and SSTO(Total Sum Of Squares)(S22). The system chooses the alarm occurrence factor(S24). The system notices the alarm occurrence while displaying the alarm occurrence factor on the screen(S26).
