Abstract : This paper intended to motivate the introduction of the expert Systems within the supervisory systems used in the automatic control of the industrial processes.
Fault detection and diagnosis is one of the most critical components of preventing accidents and ensuring the system safety of industrial processes. In this paper, we propose an integrated learning approach for jointly achieving fault detection and fault diagnosis of rare events in multivariate time series data. The proposed approach combines an autoencoder to detect a rare fault event and a long short-term memory LSTM network to classify different types of faults. The autoencoder is trained with offline normal data, which is then used as the anomaly detection. The predicted faulty data, captured by autoencoder, are put into the LSTM network to identify the types of faults. It basically combines the strong low-dimensional nonlinear representations of the autoencoder for the rare event detection and the strong time series learning ability of LSTM for the fault diagnosis. The proposed approach is compared with a deep convolutional neural network approach for fault detection and identification on the Tennessee Eastman process.

Fault detection and diagnosis in manufacturing systems: a behavioral model approach Abstract: An approach to online fault detection and diagnosis in automated manufacturing systems with discrete controls and sensing is described. The approach is based on the concept of behavioural models of the individual system components. These models, which can be developed while the system is being designed, characterize the responses of the devices in the system to arbitrary input signals over the range of acceptable operating conditions.
It seems that you're in Germany. We have a dedicated site for Germany. Authors: Chiang , L. Early and accurate fault detection and diagnosis for modern chemical plants can minimise downtime, increase the safety of plant operations, and reduce manufacturing costs. The process monitoring techniques that have been most effective in practice are based on models constructed almost entirely from process data. The goal of the book is to present the theoretical background and practical techniques for data-driven process monitoring. Process monitoring techniques presented include: Data-driven methods - principal component analysis, Fisher discriminant analysis, partial least squares and canonical variate analysis; Analytical Methods - parameter estimation, observer-based methods and parity relations; Knowledge-based methods - causal analysis, expert systems and pattern recognition.

Присоединяются зарубежные налетчики! - крикнул один из техников. - Уже обо всем пронюхали. Сьюзан отвернулась от экрана ВР к боковому монитору.
Какая редкость! - саркастически парировала Сьюзан. - Он участвовал в разработке ТРАНСТЕКСТА. Он нарушил правила. Из-за него чуть было не произошел полный крах нашей разведки. Я его выгнал.
Per favore. Sulla Vespa. Venti mille pesete. Итальянец перевел взгляд на свой маленький потрепанный мотоцикл и засмеялся.
- Yel autobus. Охранник пожал плечами. - Через сорок пять минут. Беккер замахал руками. Ну и порядки. Звук мотора, похожий на визг циркулярной пилы, заставил его повернуться. Парень крупного сложения и прильнувшая к нему сзади девушка въехали на стоянку на стареньком мотоцикле Веспа-250.

Беккер не знал, сколько времени пролежал, пока над ним вновь не возникли лампы дневного света. Кругом стояла тишина, и эту тишину вдруг нарушил чей-то голос. Кто-то звал .
