1. (Data-driven) Scheduling and Control This is to develop scheduling policies for either performance control (e.g., maximizing throughput) or logical control (e.g., avoiding deadlock), or for both of them, by considering some data obtained from system operation. Currently, we have two topics. - Feature-based Scheduling for Capacitated Re-entrant Lines - Multi-agent Scheduling 2. Process Mining This is to extract process-related information and discover a process model by observing event data in order to diagnose the system. If there is any problem in the process, then we can improve it by using some of methods in our research areas. 3. Optimization-based Data Analytics This is to develop data analysis methodologies by using optimization techniques. Currently, we are working on classification problem and trying to extend it. One specific issue is as follows: - Pattern Generation for Logical Analysis of Data (LAD) 4. Modeling and Simulation This is a method for process analysis and improvement by evaluating the system and suggesting better ways to improve its performance.
