SW16 Keynote Speakers

The SW16 committee are very pleased to advise that Alexander Verbraeck, from Delft University of Technology and Sally Brailsford, from University of Southampton, have kindly agreed to be the Keynote Speakers for our Simulation Workshop on 11 - 13 April 2016.

Alexander Verbraeck

Delft University of Technology

Abstract :

Data Driven Simulation

Given the abundant availability of big and open data for many domains, it becomes possible to generate both the structure and the behaviour of models from data. This is a task that needs careful preparation in order to maintain model validity.  Assessing data quality and metamodeling are two key ingredients for successful data driven simulation studies.  In the talk, I will show some of the challenges and solution, and illustrate them with examples from the transport sector where automatic model generation and data assimilation into discrete event models have been applied.

Short biography :

Alexander Verbraeck (MSc in applied mathematics 1987 (cum laude); PhD in logistics 1991), is a full professor at Delft University of Technology, Faculty of Technology, Policy and Management, Multi Actor Systems Department. His research focuses on modeling and simulation, especially in heavily distributed environments and using real-time data. Examples of research on these types of simulations are real-time decision making, interactive gaming using simulations, and the use of 3D virtual and augmented reality environments in simulations.  The major application domain for research is logistics and transportation. In addition Alexander has a position as adjunct professor at the R.H. Smith School of Business at the University of Maryland, USA. Here, he applies the modeling and simulation research for studying real-time supply chains. . His applied research in simulation, gaming, and training has been funded by organizations such as Maersk, Shell, KLM, Amsterdam Airport Schiphol, Port of Rotterdam, the National Forensics Institute, and Dutch Railroads. He presented over 100 refereed papers at conferences, wrote close to 20 book chapters, and published his work in a dozen journals


Sally Brailsford

University of Southampton

Abstract :

Hybrid Simulation: the best thing since sliced bread, or just a fad?

Hybrid simulation, the combination of different simulation paradigms (discrete-event simulation, system dynamics and agent-based simulation) in the same model, has become increasingly popular in recent years.  The availability and improved usability of modelling software tools such as AnyLogic and the new Vensim variant Ventity have contributed to the increased adoption of hybrid approaches.  However, is this just a passing fad, or is hybrid simulation the answer to the challenges of getting simulation models used (and useful) for a wider class of real-world problems?
This talk describes some hybrid simulation models for a range of healthcare applications, where the various simulation paradigms are combined in a range of different ways.  The challenges of model development and the rationale for the various modelling decisions are discussed.  The talk concludes with a personal reflection on the benefits and disadvantages of using hybrid models in general.

Short biography :

Sally Brailsford is Professor of Management Science at the University of Southampton. Sally has worked for over 25 years in the area of health O.R. She is Vice-President 1 of EURO and chair of the EURO Working Group on OR Applied to Health Services (ORAHS). She is one of the Editors-in-Chief of the UK OR Society journal Health Systems. She has twice won the UK OR Society's Goodeve Medal, in 2004 for modelling emergency healthcare services in Nottingham, and in 2006 for modelling chlamydia infection.
