A Smart Factory Application for using Process Mining and Machine Learning.
– Current Application Area : Manufacturing Process of Cold-Rolled Steel Products
- Heuristic Miner [Discover process flow]
- Discover process flows through drawing between the planned and unplanned process model
– Can examine the unplanned and heavy frequent process flow comparing to the planned process
– Detect unusual cases by setting up threshold, and review details of the cases
- Association Rule [Discover process problems]
- Discover problems of the process and analyses causes the through association rule model
– Estimate the approximate load of specific equipment, or discover cases that cause affect on machinery lifetime
# The red box result of the above may indicates the overload of particular cases
- Time Gap Analysis
- Check delayed and waiting process
– Find the location of delayed and waiting process, and use the data for process planning
– Express various flow for each case using time filter.
- Delta Analysis
- Comparison and analysis of process flow among processes
– Detect an unusual flow in Process B comparing to Process A
– Predict normal/abnormal flows in optimal or defined process.
- Process Planning Automation
