Collective adaptive systems provide secure and robust collaboration between heterogeneous entities such as humans and computer systems. Such entities have potentially conflicting goals that attempt to satisfy by interacting with each other. Understanding, predicting and designing their behavior and evolution requires the incorporation of technical, social and economic aspects in our models. In this presentation, we discuss cells and ensembles, a new design principle to study and construct collective adaptive systems, developed with our partners in the EU project “ALLOW ENSEMBLES”. We also show how to apply this principle in the study and design of an integrated and multimodal urban mobility system, where we model the interactions of various entities by means of game theoretic techniques.
Christos Nikolaou, Ph.D. (University of Crete)
Professor, Computer Science Department, University of Crete, Greece. Led research group in IBM T.J. Watson Research Center (NY, USA), to introduce multiprocessor technology and load balancing in commercial transaction processing systems (CICS, MVS, IMS, DB2); cooperated with other research and development groups. Performance and availability were dramatically increased for the flagship IBM systems of the time ('80s and '90s). IBM market leadership position maintained, revenues increased significantly, profit margins remained stable. Was awarded the IBM Outstanding Innovation Award (1993). As Rector (President) of the leading Research University in Greece (U. of Crete) ('99-'04), among other initiatives, he opened the University to international cooperation (and was awarded the “Chevalier de l’Ordre de Palmes Academiques” by the French Republic, 2006), spearheaded a major campus construction effort, designed and led the effort for a federated academic digital library system for Greek Universities. Was appointed by the Greek Parliament, Chairman of the National Education Council (2004-’05), and invited as University Evaluator, at the Institutional Evaluator Program (IEP) of the European University Association (EUA) (2006-present). Founded the Transformation Services Laboratory (TSL, 2006-present) that provides technological and managerial guidance to clients around the world. Pioneered method that accurately estimates the value of a service system (value network) and can guide to the deployment of optimal strategies for a consortium of service providers. Best paper awards in large international conferences (1st Int. Conf. on Advanced Service Computing, 2009; 6th Int. Conf. on Internet and Web Applications and Services (ICIW 2011). Diploma, Mechanical and Electrical Engineering, 1977, National Technical University of Athens, Greece; MSc, Applied Mathematics, 1979, Harvard University, USA; PhD, Applied Mathematics, 1982, Harvard University, USA.
