In this paper, we offer a characterization of ensembles, as the main concept around which systems that exhibit collective adaptability can be built. Our conceptualization of ensembles enables to define a collective adaptive system as an emergent aggregation of autonomous and self-adaptive process-based elements. To elucidate our approach to ensembles and collective adaptation, we draw an example from a scenario in the urban mobility domain, we describe an architecture that enables that approach, and we show how our approach can address the problems posed by the motivating scenario. date: 2014-09 publisher: IEEE pagerange: 151-156 event_title: Self-Adaptive and Self-Organizing Systems (SASO), 2014 IEEE Eighth International Conference on id_number: 10.1109/SASO.2014.28 refereed: TRUE isbn: 978-1-4799-5367-7 book_title: Proceedings of Eighth International Conference on the Self-Adaptive and Self-Organizing Systems (SASO) official_url: http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=7001011&isnumber=7000942 citation: Bucchiarone, Antonio and Mezzina, Claudio Antares and Pistore, Marco and Raik, Heorhi and Valetto, Giuseppe Collective adaptation in process-based systems.
