Soziale Medien werden heutzutage st{\"a}ndig und von fast jedem genutzt, vor allem von Jugendlichen und jungen Erwachsenen. Vielen ist aber nicht bewusst, dass sich die Nutzung negativ auf sie und ihre Gesundheit auswirken kann. Eine Kampagne soll daran etwas {\"a}ndern. Soziale Medien bzw. der Content, der die Nutzer:innen negativ beeinflusst, ist wie ein Monster, vor dem sich die Nutzer:innen in acht nehmen m{\"u}ssen. Angesprochen werden haupts{\"a}chlich 12-29-j{\"a}hrige, die Soziale Medien nutzen. Die Kampagne soll durch verschiedene Maßnahmen wie Plakatwerbung und Posts auf Social Media Kan{\"a}len, den negativen Auswirkungen von Social Media Nutzung entgegenwirken. Sie soll {\"u}ber die Auswirkungen aufkl{\"a}ren und zu einem bewussteren Umgang mit Sozialen Netzwerken anregen.}, language = {de} } @article{StepkesZimmermannMuelleretal.2007, author = {Stepkes, Hermann and Zimmermann, Jochen and M{\"u}ller, Karsten and Siekmann, Marko and Niessen, J{\"u}rgen and Hofmann, Daniela and Pinnekamp, Johannes}, title = {Georadarmess-System zur Kanalsanierung}, series = {wwt Wasserwirtschaft und Wassertechnik. 2007, H. 3}, journal = {wwt Wasserwirtschaft und Wassertechnik. 2007, H. 3}, issn = {1438-5716}, pages = {16 -- 19}, year = {2007}, language = {de} } @inproceedings{StepkesZimmermannMuelleretal.2007, author = {Stepkes, Hermann and Zimmermann, J. and M{\"u}ller, Karsten and Siekmann, Marko and Pinnekamp, Josef}, title = {Economical rehabilitation of sewer systems by ground penetration radar investigations}, series = {Strategic asset management of water supply and wastewater infrastructures : invited papers from the 2nd IWA Leading Edge Conference on Strategic Asset Management (LESAM), Lisbon, October [17 - 19] 2007 / ed. by Helene Alegre and Maria do C{\´e}u Almeida}, booktitle = {Strategic asset management of water supply and wastewater infrastructures : invited papers from the 2nd IWA Leading Edge Conference on Strategic Asset Management (LESAM), Lisbon, October [17 - 19] 2007 / ed. by Helene Alegre and Maria do C{\´e}u Almeida}, publisher = {IWA Publ.}, address = {London}, isbn = {9781843391869}, pages = {501 -- 520}, year = {2007}, language = {en} } @article{StephanGueth1984, author = {Stephan, J{\"u}rgen and G{\"u}th, Werner}, title = {Equilibrium Selection in the One Seller and Many Buyers Game / G{\"u}th, Werner, Stephan, J{\"u}rgen}, series = {Zeitschrift f{\"u}r National{\"o}konomie.

The usage of common parts and modules across product families can potentially reduce production costs. Yet, increasing commonality typically results in overdesign of individual products. Multi domain virtual prototyping enables designers to evaluate costs and technical feasibility of different single product designs at reasonable computational effort in early design phases. However, savings by platform commonality are hard to quantify and require detailed knowledge of e.g. the production process and the supply chain. Therefore, we present and evaluate a multi-objective metamodel-based optimization algorithm which enables designers to explore the trade-off between high commonality and cost optimal design of single products.}, language = {en} } @incollection{StengerAltherrAbel2019, author = {Stenger, David and Altherr, Lena and Abel, Dirk}, title = {Machine learning and metaheuristics for black-box optimization of product families: a case-study investigating solution quality vs. computational overhead}, series = {Operations Research Proceedings 2018}, booktitle = {Operations Research Proceedings 2018}, publisher = {Springer}, address = {Cham}, isbn = {978-3-030-18499-5 (Print)}, doi = {10.1007/978-3-030-18500-8_47}, pages = {379 -- 385}, year = {2019}, abstract = {In product development, numerous design decisions have to be made. Multi-domain virtual prototyping provides a variety of tools to assess technical feasibility of design options, however often requires substantial computational effort for just a single evaluation. A special challenge is therefore the optimal design of product families, which consist of a group of products derived from a common platform. Finding an optimal platform configuration (stating what is shared and what is individually designed for each product) and an optimal design of all products simultaneously leads to a mixed-integer nonlinear black-box optimization model. We present an optimization approach based on metamodels and a metaheuristic. To increase computational efficiency and solution quality, we compare different types of Gaussian process regression metamodels adapted from the domain of machine learning, and combine them with a genetic algorithm. We illustrate our approach on the example of a product family of electrical drives, and investigate the trade-off between solution quality and computational overhead.}, language = {en} } @inproceedings{StenderRitz2003, author = {Stender, Michael and Ritz, Thomas}, title = {Modeling of business-to-business mobile commerce processes}, series = {Electronic proceedings / ICPR 17, 17th International Conference on Production Research [Blacksburg, Virginia, USA, August 3 - 7, 2003]}, booktitle = {Electronic proceedings / ICPR 17, 17th International Conference on Production Research [Blacksburg, Virginia, USA, August 3 - 7, 2003]}, edition = {CD-ROM-Ausg.}, address = {Blacksburg, Va.}, isbn = {0-9721257-3-6}, year = {2003}, language = {en} } @inproceedings{StenderRitz2003, author = {Stender, Michael and Ritz, Thomas}, title = {{\"U}berbetriebliche Ad-hoc-Anwendungsintegration im Mobile Business}, series = {Wirtschaftsinformatik 2003 : Medien, M{\"a}rkte, Mobilit{\"a}t: - Bd. 1}, booktitle = {Wirtschaftsinformatik 2003 : Medien, M{\"a}rkte, Mobilit{\"a}t: - Bd. 1}, editor = {Uhr, Wolfgang}, publisher = {Physica-Verl.}, address = {Heidelberg}, isbn = {3-7908-0111-9}, pages = {103 -- 118}, year = {2003}, language = {de} }
