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} } @inbook{SchiendorferKnappSteghoeferetal.2015, author = {Schiendorfer, Alexander and Knapp, Alexander and Stegh{\"o}fer, Jan-Philipp and Anders, Gerrit and Siefert, Florian and Reif, Wolfgang}, title = {Partial Valuation Structures for Qualitative Soft Constraints}, booktitle = {Software, Services, and Systems: Essays Dedicated to MartinWirsing on the Occasion of His Retirement from the Chair of Programming and Software Engineering}, editor = {De Nicola, Rocco and Hennicker, Rolf}, publisher = {Springer}, address = {Cham}, isbn = {978-3-319-15545-6}, doi = {https://doi.org/10.1007/978-3-319-15545-6_10}, pages = {115 -- 133}, year = {2015}, language = {en} } @inbook{AndersSiefertSchiendorferetal.2016, author = {Anders, Gerrit and Siefert, Florian and Schiendorfer, Alexander and Seebach, Hella and Stegh{\"o}fer, Jan-Philipp and Eberhardinger, Benedikt and Kosak, Oliver and Reif, Wolfgang}, title = {Specification and Design of Trust-Based Open Self-Organising Systems}, booktitle = {Trustworthy Open Self-Organising Systems}, editor = {Reif, Wolfgang and Anders, Gerrit and Seebach, Hella and Stegh{\"o}fer, Jan-Philipp and Andr{\´e}, Elisabeth and H{\"a}hner, J{\"o}rg and M{\"u}ller-Schloer, Christian and Ungerer, Theo}, publisher = {Birkh{\"a}user}, address = {Cham}, isbn = {978-3-319-29201-4}, doi = {https://doi.org/10.1007/978-3-319-29201-4_2}, pages = {17 -- 54}, year = {2016}, language = {en} } @article{AndersSchiendorferSiefertetal.2015, author = {Anders, Gerrit and Schiendorfer, Alexander and Siefert, Florian and Stegh{\"o}fer, Jan-Philipp and Reif, Wolfgang}, title = {Cooperative Resource Allocation in Open Systems of Systems}, volume = {10}, pages = {11}, journal = {ACM Transactions on Autonomous and Adaptive Systems}, number = {2}, publisher = {ACM}, address = {New York}, issn = {1556-4665}, doi = {https://dl.acm.org/doi/10.1145/2700323}, year = {2015}, language = {en} } @inbook{SchiendorferAndersSteghoeferetal.2016, author = {Schiendorfer, Alexander and Anders, Gerrit and Stegh{\"o}fer, Jan-Philipp and Reif, Wolfgang}, title = {Abstraction of Heterogeneous Supplier Models in Hierarchical Resource Allocation}, booktitle = {Transactions on Computational Collective Intelligence XX}, editor = {Nguyen, Ngoc Thanh and Kowalczyk, Ryszard and Duval, B{\´e}atrice and van den Herik, Jaap and Loiseau, Stephane and Filipe, Joaquim}, publisher = {Springer}, address = {Cham}, isbn = {978-3-319-27543-7}, doi = {https://doi.org/10.1007/978-3-319-27543-7_2}, pages = {23 -- 53}, year = {2016}, language = {en} } @inproceedings{SchiendorferSteghoeferReif2014, author = {Schiendorfer, Alexander and Stegh{\"o}fer, Jan-Philipp and Reif, Wolfgang}, title = {Synthesised Constraint Models for Distributed Energy Management}, booktitle = {Proceedings of the 2014 Federated Conference on Computer Science and Information Systems (FedCSIS)}, publisher = {IEEE}, address = {Piscataway}, isbn = {978-83-60810-58-3}, url = {https://ieeexplore.ieee.org/document/6933199}, pages = {1529 -- 1538}, year = {2014}, 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} }
