Jan H. van Schuppen is affiliated with the the research institute Centrum voor Wiskunde en Informatica (CWI) in Amsterdam, The Netherlands and as Full Professor (part time) with the Department of Mathematics of the Delft University of Technology in Delft, The Netherlands.
Van Schuppen’s research interests include control of discrete-event systems and of hybrid systems, stochastic control, realization, and system identification. In applied research his interests include engineering problems of control of motorway traffic, of communication networks, and control and system theory for the life sciences.
He is Co-Editor of the journal Mathematics of Control, Signals, and Systems, was Associate Editor-at-Large of the journal IEEE Transactions Automatic Control, and was Department Editor of the journal Discrete Event Dynamic Systems.
He was and is the advisor of 17 Ph.D. students, 12 post-docs, and 8 master level students.
Finally, he is also the coordinator of the C4C Project (CON4COORD, Grant agreement INFSO-ICT-223844).

Control engineering problems of control of distributed and of hierarchical discrete-events systems are mentioned first. These problems are then classified by the structure of the systems. Distributed control of distributed DES has as major control issues: (1) What it the state of the supervisor in such a problem? (2) How to determine a global optimum of how to approximate it? The state of the art will be described. Further research will be indicated. Next coordination control will be formulated. In such a structure a coordinator communicates events to two or more subsystems. Within this structure one can carry out control synthesis and prove nonblockingness. Control issues are: (1) What is the state of the supervisor? (2) How to determine an equilibrium? Control of distributed systems with communication between the supervisors leads to the control issues: (1) How to interleave the events of two or more event streams? (2) What is the state of the supervisor? (3) How to determine an equilibrium? The current state of the problem will be summarized. Control of hierarchical systems can take several forms. Hierarchical systems may be due to engineering modeling, abstraction, or to model formulation. Control issues are then: (1) What are necessary and sufficient conditions for controllability of a hierarchical system?
