  • Publication number: 20210240174
    Abstract: A monitoring system that monitors a monitoring-target system is disclosed. The monitoring system includes one or more storage apparatuses that store a program, and one or more processors that operate according to the program. The one or more processors determine an estimated value of a monitoring-target response variable of the monitoring-target system on a basis of measurement data included in test data of the monitoring-target system and a causal structure model of the monitoring-target system. The one or more processors decide whether an abnormality has occurred in the monitoring-target system on a basis of a result of a comparison between a measurement value of the monitoring-target response variable included in the test data, and the estimated value.

  • Publication number: 20190265679
    Abstract: The object of the invention is to estimate a causal relation between predetermined data at high precision and at ease, taking nonlinearity between the data into consideration. A work improvement support device is comprised of a nonlinear term adding unit for calculating a nonlinear value as for respective working data in the working data group and adding the nonlinear value to a working data group, a multiple regression analysis unit for calculating a regression formula as for respective working data according to the multiple linear regression analysis, a data group setting unit for determining whether there is a linear term in the calculated regression formula and setting the predetermined data comprising the linear term and the objective variable of the regression formula as the same group, and an explanatory variable candidate selecting unit for selecting the working data, excluding the predetermined data, as the explanatory variable candidates for the multiple linear regression analysis.
