Dr. Szczerbicka has an M.Sc. in Applied Mathematics and Ph.D. in Computer Science from the Warsaw University of Technology, Poland. She has been on the faculties of Warsaw University, University of Karlsruhe, Germany and the University of Bremen, Germany. She has been a full professor at the University of Hannover since 2000, where she was the chair of the Institute of the Computer Science for two years. She spent her sabbaticals at the University of California, Berkeley and the University of Central Florida, Orlando. She was awarded with the Erskin Fellowship from the University of Canterbury, NZ, for June-October 2005. Currently she leads a research group SIM-Simulation and Modelling. She works actively in the Federation of European Simulation Societies (Eurosim), the German Simulation Society (Asim) and the Society for Computer Simulation (SCS) as a Vice President for Publications and a chair of the Technical Council Methodology. She serves as a member of an editorial board of the book series Frontiers of Simulation. Recently she has been involved in international activities on establishing a curriculum for an educational program for a simulation degree and a certification of simulation professionals as a member of the international Modelling & Simulation Professional Certification Implementation Group, Washington, USA. Since 1990 she is an Associate Member of the McLeod Institutes of Simulation Sciences, USA. Since 1992 she has been conducting the FG4.5.3 Working Group Simulation and Artificial Intelligence of the German Society of Computer Science (GI). She is an area editor of the Simulation: Transactions of the SCS. She has been certified as Pioneer a Simulation Professional by the M&SPCC. She has been involved in organization of numerous conferences in the field of simulation, program committee member, and as a track or general chair as well. She is an author or co-author of more than 90 papers and co-author of one book. Four of her papers have been selected for the best paper award. Her research interests are in the field of modelling performance and performability of large scale, discrete dynamic systems. She is interested in the application of methods of artificial intelligence to modelling, simulation, optimization and validation as well as distributed and web-based simulation. Her research is frequently triggered by industrial co-operations. She is currently involved in establishing a Centre for Integrated Simulation at the University of Hannover.
Challenges in on-line simulation
In common applications discrete event simulation is used for purpose of the prediction of the behaviour of complex systems before the system is put into operation. The major technical issue in the methodology is primarily the statistical analysis of simulation output. In recent years however another application of simulation is getting more attention. Motivated by technical feasibility of fast simulation and processing large amount data in real time on one side and requirements for fast adaptation of complex manufacturing, transportation systems or computer networks in which the best performance can not be reached by means of off-line simulation on the other side, on-line simulation becomes a topic of interest in management of complex systems.
The talk will introduce the concept of on-line simulation, specific properties and resulting requirements on the methodology. We can describe on-line simulation as a technique for improving the performance of systems prone to changing characteristics of the environment and to maintain system attributes in a proactive manner. The talk will conclude with some applications.
Analysis of interaction of protocols in ad-hoc networks
Ad-hoc networks are self-organizing networks, which operate without predefined infrastructure and careful design capturing all phenomena featured by these systems. The majority of research addresses only specific aspects of protocol design viewing protocols separately. In the talk performance of the most important parts of the protocol stack MAC and Routing mechanism will be considered jointly in context of factors determining the operation of the network. The focus will be on the methodological aspects of the analysis of the experimental data. The protocol interaction will be analysed with Analysis of Variance (ANOVA).
