The system's mathematical tool is grounded on similarity-based modeling methods. The system generates a reference digital pattern, i.e. a set of the facility's mathematical models which describes the error-free behavior of equipment in various modes of operation. To build it, the ideology of the Hotelling T2 Control Charts is used. The model value is calculated by means of the state matrix and using the similarity operator for each measured value. The residual and standard deviation are calculated using the difference between the reference and actually measured values for each parameter. Residuals are normalized and the integral criterion of technical condition T2 is calculated on an aggregate basis. Owing to analyzing the T2 criterion, changes in the technical condition of equipment are predicted and all possible dependences of parameters are monitored.<ref name='jcement'>{{Cite web|lang=ru|url=https://jcement.ru/magazine/vypusk-1-2021/perspektivy-ispolzovaniya-sistemy-prediktivnoy-diagnostiki-v-tsementnoy-promyshlennosti/|title=Перспективы использования системы предиктивной диагностики в цементной промышленности}}</ref>

 The system's mathematical tool is grounded on similarity-based modeling methods. The system generates a reference digital pattern, i.e. a set of the facility's mathematical models which describes the error-free behavior of equipment in various modes of operation. To build it, the ideology of the Hotelling T2 Control Charts is used. The model value is calculated by means of the state matrix and using the similarity operator for each measured value. The residual and standard deviation are calculated using the difference between the reference and actually measured values for each parameter. Residuals are normalized and the integral criterion of technical condition T2 is calculated on an aggregate basis. Owing to analyzing the T2 criterion, changes in the technical condition of equipment are predicted and all possible dependences of parameters are monitored.<ref name='jcement'>{{Cite web|lang=ru|url=https://jcement.ru/magazine/vypusk-1-2021/perspektivy-ispolzovaniya-sistemy-prediktivnoy-diagnostiki-v-tsementnoy-promyshlennosti/|title=Перспективы использования системы предиктивной диагностики в цементной промышленности}}</ref>
