Abstract
Anomaly detection plays a critical role in ensuring the quality and safety of industrial processes. Process mining, as an emerging technology, has proven effective in extracting knowledge and process rules inherent in process events. However, industrial time series data possess characteristics such as high noise, and data redundancy, posing challenges for accurately assessing system anomalies using traditional data-driven methods. To address these challenges, this paper proposes a Trend-Value Fusion Process Mining (TVPM) approach based on the representation of industrial process events to tackle anomaly detection in industrial processes. Firstly, TVPM introduces a fusion measure that combines data trends and mean-value to provide a comprehensive description of operating events in industrial processes. This fusion measure serves as a vital tool for capturing the complex details and features of industrial events. Additionally, a novel process discovery algorithm is developed to extract behavioral patterns and sequence information from events. Finally, a process abnormal state detection model is constructed by leveraging the comprehensive and in-depth information obtained from TVPM. The proposed method is applied to an industrial coal gasification process, yielding satisfactory results.
期刊介绍:
This international journal covers the application of control theory, operations research, computer science and engineering principles to the solution of process control problems. In addition to the traditional chemical processing and manufacturing applications, the scope of process control problems involves a wide range of applications that includes energy processes, nano-technology, systems biology, bio-medical engineering, pharmaceutical processing technology, energy storage and conversion, smart grid, and data analytics among others.
Papers on the theory in these areas will also be accepted provided the theoretical contribution is aimed at the application and the development of process control techniques.
Topics covered include:
• Control applications• Process monitoring• Plant-wide control• Process control systems• Control techniques and algorithms• Process modelling and simulation• Design methods
Advanced design methods exclude well established and widely studied traditional design techniques such as PID tuning and its many variants. Applications in fields such as control of automotive engines, machinery and robotics are not deemed suitable unless a clear motivation for the relevance to process control is provided.
