Jan Claes is a PhD student studying how to merge event logs from different sources to facilitate process mining for supply chains. His research involves developing algorithms like a genetic algorithm and artificial immune system technique. He is currently visiting another university to apply process mining to modeling experiment logs. His future work includes submitting papers on his merging techniques and improving collaborative modeling.

9. 1. Process Mining
Processes are supported by IT systems
IT systems record actual process data
Process data can be used to automatically
 Discover process model
 Check conformance with existing process info
 Extend existing process model
Attention Process Mining
 Only As-Is
 Only (correctly) recorded information

11. 1. Process Mining steps
 Preparation
 Collect data: find event information
 Merge data: from different sources
 Structure data: group per instance
 Convert data: to tool specific format
 Process mining
 Make decisions, take action
Manual task Analysts needed in most cases
Automated task Less human involvement needed
