Trace Based Visualization and Analysis for Supervisory Control Systems
Satoru Takahashi, Takuya Ishioka · IEEJ Transactions on Industry Applications · 2000
This paper describes a tool for performance analysis and verification of supervisory control systems based on traced information. When verifying large-scale systems in the view of their rolls and functions, analysis of task behaviours is expected rather than that of system resources. The proposed tool aims at task-level understanding by visualizing interaction between tasks. Another feature of the tool is to distinguish unusual traces by identifying frequent trace patterns based on dictionary making in data compressing algorithm. An example to show usefulness of the proposed tool is given.
