A Novel Method of Digital Twin-Based Manufacturing Process State Modeling and Incremental Anomaly Detection
نویسندگان
چکیده
In the manufacturing process, digital twin technology can provide real-time mapping, prediction, and optimization of physical process in information world. order to realize complete expression accurate identification changes state a framework incremental learning driven by stream data is proposed. Additionally, novel method data-driven equipment operation modeling anomaly detection proposed based on twin. Firstly, hierarchical finite machine (HFSM) for was completely express state. Secondly, used detect job data, so as change status real time. Furthermore, F1 value time consumption algorithm were compared analyzed using general dataset. Finally, applied practical case development welding manufacturer’s system. The flexibility model calculated quantitative method. results show that help system mapping quickly, effectively, flexibly.

Digital Twin of Manufacturing Systems
The digitization of manufacturing systems is at the crux of the next industrial revolutions. The digital representation of the “Physical Twin,” also known as the “Digital Twin,” will help in maintaining the process quality effectively by allowing easy visualization and incorporation of cognitive capability in the system. In this technical report, we tackle two issues regarding the Digital Twin:...
متن کاملDynamic anomaly detection by using incremental approximate PCA in AODV-based MANETs
Mobile Ad-hoc Networks (MANETs) by contrast of other networks have more vulnerability because of having nature properties such as dynamic topology and no infrastructure. Therefore, a considerable challenge for these networks, is a method expansion that to be able to specify anomalies with high accuracy at network dynamic topology alternation. In this paper, two methods proposed for dynamic anom...

15 صفحه اولAnomaly Based Intrusion Detection Using Incremental Approach: A Survey
As the communication industry has connected distant corners of the globe using advances in network technology, intruders or attackers have also increased attacks on networking infrastructure commensurately. System administrators can attempt to prevent such attacks using intrusion detection tools and systems. There are many commercially available signature-based Intrusion Detection Systems (IDSs...
متن کاملA Novel Patch-Based Digital Signature
In this paper a new patch-based digital signature (DS) is proposed. The proposed approach similar to steganography methods hides the secure message in a host image. However, it uses a patch-based key to encode/decode the data like cryptography approaches. Both the host image and key patches are randomly initialized. The proposed approach consists of encoding and decoding algorithms. The encodin...
