@inproceedings{13331, abstract = {{Communication in online social networks has been analyzed for some time regarding the expression of sentiments. So far, very little is known about the relationship between sentiments and network emergence, dissemination patternsand possible differences between positive and negative sentiments. The dissemination patterns analyzed in this study consist of network motifs based on triples of actors and the ties among them. These motifs are associated with common social network effects to derive meaningful insights about dissemination activities. The data basis includes several thousand social networks with textual messages classified according to embedded positive and negative sentiments. Based on this data, sub-networks are extracted and analyzed with a dynamic network motif analysis to determine dissemination patterns and associated network effects. Results indicate that the emergence of digital social networks exhibits a strong tendency towards reciprocity, followed by the dominance ofhierarchy as an intermediate step leading to social clustering with hubs and transitivity effects for both positive and negative sentiments to the same extend. Sentiments embedded in exchanged textual messages do only play a secondary role in network emergence and do not express differences regarding the emergence of network patterns.}}, author = {{Hillmann, Robert and Trier, Matthias}}, booktitle = {{Proceedings of the 2012 IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining}}, isbn = {{9780769547992}}, keywords = {{Social Network Analysis, Dynamic Network Motif Analysis, Sentiment Dissemination, Networking Effects, Triads}}, pages = {{510--515}}, publisher = {{IEEE}}, title = {{{Dissemination Patterns and Associated Network Effects of Sentiments in Social Networks}}}, year = {{2012}}, } @article{3075, author = {{Schmitz, Hendrik}}, journal = {{Applied Economics}}, number = {{34}}, pages = {{4455--4468}}, title = {{{More health care utilization with more insurance coverage?

It aims either at the comparison of competitive designs or the identification of a “best possible” configuration of the simulation model. Here, combinatorial techniques of simulation and optimization methods support the user in finding optimal solutions, which typically result in long computation times and though often prohibit a practical application in today’s industry. This paper presents a fast converging procedure as a combination of a swarm heuristic, namely the particle swarm optimization, and the material flow simulation to close this gap. Faster convergence is realized by a specific extension of classic PSO implementations.

Current approaches to reduce CO2 emission on an operational level ignore time-related objectives and focus on simultaneous optimisation of economic and ecological objectives. In general, considering the minimisation of CO2 emissions in transportation scheduling introduces a trade-off between economic and ecological concerns. The concept of eco-efficiency is important in order to evaluate the economical value and ecological quality of business decisions. Nevertheless, this concept has primarily been applied to strategic decisions. In the present paper we demonstrate the applicability of this concept to operative decisions and introduce a bi-objective evolutionary optimisation approach for the approximation of CO2-efficient schedules in an international transportation problem. }}, author = {{Kl{\, Benjamin and Pater, Jan-Patrick and Irohara, Takashi and Xue, Yudong}}, journal = {{International Journal of Engineering Management and Economic}}, number = {{3}}, pages = {{212--236}}, title = {{{Bi-objective-optimisation of an international transportation problem for CO2-efficient schedules}}}, volume = {{3}}, year = {{2012}}, } @inproceedings{25815, author = {{Renken, Hendrik and Eichert, Felix Alexander and Brandt, Sascha and Klaas, Alexander}}, publisher = {{ASME}}, title = {{{Visualization and Collaborative Editing of Simulation Models With Heterogeneous Clients - Implemented Into the Simulator d3fact}}}, volume = {{2}}, year = {{2012}}, } @inproceedings{25817, author = {{Dangelmaier, Wilhelm and Laroque, Christoph and Delius, Robin and Streichhan, Jenny}}, title = {{{Development of cost-effective spare parts logistics for a solar technology provider under monet {\ "a} rer Ber {\" u} consideration of resulting CO2 emissions}}}, year = {{2012}}, } @inproceedings{25814, author = {{Hartmann, Philip and Laroque, Christoph}}, pages = {{13--30}}, publisher = {{EconPapers}}, title = {{{Kontinuierliche Adaption von Lieferketten durch Leistungsbewertung und -steuerung dynamischer Gesch{\"a}ftsprozesse}}}, volume = {{XII}}, year = {{2012}}, } @inproceedings{25818, author = {{Fischer, Jan-Hendrik and Delius, Robin and Horstkemper, Dennis and Laroque, Christoph}}, title = {{{Comparing a hybrid simulation & optimization approach with a purely stochastic optimization to increase the robustness of production plans}}}, year = {{2012}}, } @article{25821, author = {{Laroque, Christoph and Delius, Robin and Fischer, Jan-Hendrik}}, journal = {{International Journal on Advances in Systems and measurements}}, title = {{{Increase of robustness in production plans using a hybrid optimization and simulation approach}}}, year = {{2012}}, } @inproceedings{25816, author = {{Kl{\"o}pper, Benjamin and Pater, Jan-Patrick and Dangelmaier, Wilhelm}}, booktitle = {{Proceedings of the 9th IEEE International Conference on Industrial Informatics}}, pages = {{1086--1091}}, title = {{{Parallel scheduling for evolving manufacturing systems}}}, year = {{2012}}, } @book{25823, author = {{Fischer, J and Dangelmaier, Wilhelm and Nastansky, Ludwig and Suhl, L}}, publisher = {{Erich Schmidt}}, title = {{{Building blocks of business informatics - basics and applications}}}, year = {{2012}}, } @article{25820, author = {{Kaganova, Ekaterina}}, journal = {{Applied Mathematical Optimization and Modelling}}, title = {{{Robust solution approach to an uncertain CLSP problem}}}, year = {{2012}}, } @article{25827, abstract = {{Persistent trends like quickly changing production programs, increasing customer individual manufacturing and Sustainable Manufacturing create complex systems of objectives in manufacturing control.
