Our approach to deal with this increasing complexity is to employ a hierarchical "regio-central" mechanism. It requires two techniques: (1) the synthesis of several models of agents providing a certain resource into a centrally and efficiently solvable optimisation problem and (2) the creation of an abstracted version of this centralised model that reduces its complexity when passing it on to higher layers. We present algorithms to create such synthesised and abstracted models in a fully automated way and demonstrate empirically that the obtained solutions are comparable to central solutions but scale better in an example taken from energy management.}, language = {en} } @inproceedings{AndersSchiendorferSteghoeferetal.2014, author = {Anders, Gerrit and Schiendorfer, Alexander and Stegh{\"o}fer, Jan-Philipp and Reif, Wolfgang}, title = {Robust Scheduling in a Self-Organizing Hierarchy of Autonomous Virtual Power Plants}, booktitle = {ARCS 2014 - 27th International Conference on Architecture of Computing Systems: Workshop Proceedings}, editor = {Stechele, Walter and Wild, Thomas}, publisher = {VDE Verlag}, address = {Berlin}, isbn = {978-3-8007-3579-2}, url = {https://www.vde-verlag.de/proceedings-en/563579019.html}, year = {2014}, language = {en} } @inproceedings{SchiendorferLassnerAndersetal.2015, author = {Schiendorfer, Alexander and Lassner, Christoph and Anders, Gerrit and Reif, Wolfgang and Lienhart, Rainer}, title = {Active Learning for Efficient Sampling of Control Models of Collectives}, booktitle = {Proceedings: 2015 IEEE 9th International Conference on Self-Adaptive and Self-Organizing Systems: SASO 2015}, publisher = {IEEE}, address = {Los Alamitos}, doi = {https://doi.org/10.1109/SASO.2015.13}, pages = {51 -- 60}, year = {2015}, language = {en} }
