Since uncertainties about future developments increase planning difficulty, flexibility potentials such as synergies between the electricity, gas, heat, and transport sector often remain unused. In this paper, we therefore present a novel module-based concept for a decision support system that helps distribution network planners to identify cross-sectoral synergies and to select optimal network assets such as transformers, cables, pipes, energy storage systems or energy conversion technology. The concept enables long-term transformation plans and supports distribution network planners in designing reliable, sustainable and cost-efficient distribution networks for future demands.","lang":"eng"}],"department":[{"_id":"534"},{"_id":"66"},{"_id":"277"}],"language":[{"iso":"eng"}],"oa":"1","type":"conference","publication":"Energy Informatics and Electro Mobility ICT","title":"Towards a Decision Support System for Cross-Sectoral Energy Distribution Network Planning","status":"public","main_file_link":[{"open_access":"1","url":"https://oops.uni-oldenburg.de/5084/7/proceedings_ow_sto_2021.pdf#page=41"}],"author":[{"first_name":"Jonas","last_name":"Kirchhoff","id":"39928","full_name":"Kirchhoff, Jonas"},{"id":"32685","full_name":"Burmeister, Sascha Christian","last_name":"Burmeister","first_name":"Sascha Christian"},{"full_name":"Weskamp, Christoph","first_name":"Christoph","last_name":"Weskamp"},{"last_name":"Engels","first_name":"Gregor","id":"107","full_name":"Engels, Gregor"}],"editor":[{"first_name":"Michael H.","last_name":"Breitner","full_name":"Breitner, Michael H."},{"last_name":"Lehnhoff","first_name":"Sebastian","full_name":"Lehnhoff, Sebastian"},{"last_name":"Nieße","first_name":"Astrid","full_name":"Nieße, Astrid"},{"last_name":"Staudt","first_name":"Philipp","full_name":"Staudt, Philipp"},{"last_name":"Weinhardt","first_name":"Christof","full_name":"Weinhardt, Christof"},{"full_name":"Werth, Oliver","last_name":"Werth","first_name":"Oliver"}],"_id":"21093"},{"intvolume":" 140","year":"2021","type":"journal_article","date_created":"2020-10-27T13:28:21Z","oa":"1","file":[{"date_created":"2020-10-27T13:31:01Z","access_level":"open_access","content_type":"application/pdf","relation":"main_file","file_size":440903,"date_updated":"2020-10-27T13:31:01Z","file_id":"20213","file_name":"DECSUP-D-20-00312 - PREPUBLICATION.pdf","creator":"hsiemes"}],"status":"public","issue":"January","keyword":["Ideational impact","citation classification","academic recommender systems","natural language processing","deep learning","cumulative tradition"],"date_updated":"2022-06-10T06:55:32Z","publication":"Decision Support Systems","file_date_updated":"2020-10-27T13:31:01Z","has_accepted_license":"1","citation":{"bibtex":"@article{Prester_Wagner_Schryen_Hassan_2021, title={Classifying the Ideational Impact of Information Systems Review Articles: A Content-Enriched Deep Learning Approach}, volume={140}, number={January113432}, journal={Decision Support Systems}, author={Prester, Julian and Wagner, Gerit and Schryen, Guido and Hassan, Nik Rushdi}, year={2021} }","short":"J.

It is defined in stark contrast to total citation impact, a measure predominantly used in research evaluation that assumes that all citations are equal. Understanding ideational impact is critical for evaluating research impact and understanding how scientific disciplines build a cumulative tradition. Research has only recently developed automated citation classification techniques to distinguish between different types of citations and generally does not emphasize the conceptual content of the citations and its ideational impact. To address this problem, we develop Deep Content-enriched Ideational Impact Classification (Deep-CENIC) as the first automated approach for ideational impact classification to support researchers' literature search practices. We evaluate Deep-CENIC on 1,256 papers citing 24 information systems review articles from the IT business value domain. We show that Deep-CENIC significantly outperforms state-of-the-art benchmark models. We contribute to information systems research by operationalizing the concept of ideational impact, designing a recommender system for academic papers based on deep learning techniques, and empirically exploring the ideational impact of the IT business value domain.\r\n","lang":"eng"}],"language":[{"iso":"eng"}],"department":[{"_id":"277"}],"title":"Classifying the Ideational Impact of Information Systems Review Articles: A Content-Enriched Deep Learning Approach","volume":140,"ddc":["000"],"_id":"20212","author":[{"first_name":"Julian","last_name":"Prester","full_name":"Prester, Julian"},{"full_name":"Wagner, Gerit","last_name":"Wagner","first_name":"Gerit"},{"first_name":"Guido","last_name":"Schryen","id":"72850","full_name":"Schryen, Guido"},{"full_name":"Hassan, Nik Rushdi","first_name":"Nik Rushdi","last_name":"Hassan"}]},{"date_created":"2020-12-29T11:52:03Z","oa":"1","type":"journal_article","year":"2021","intvolume":" 58","keyword":["Literature review","review papers","scientometric","scientific impact","citation analysis"],"issue":"3","file":[{"date_created":"2020-12-29T11:49:57Z","access_level":"open_access","file_id":"20845","file_name":"INFMAN_Scientific Impact of Review Papers - Prepublication version.pdf","creator":"hsiemes","file_size":1584950,"date_updated":"2020-12-29T11:49:57Z","relation":"main_file","content_type":"application/pdf"}],"status":"public","citation":{"mla":"Wagner, Gerit, et al. “Which Factors Affect the Scientific Impact of Review Papers in IS Research?

While some are cited twice a day, others accumulate single digit citations over a decade. The magnitude of these differences prompts us to analyze what distinguishes those reviews that have proven to be integral to scientific progress from those that might be considered less impactful. Our results highlight differences between reviews aimed at describing, understanding, explaining, and theory testing. Beyond the control variables, they demonstrate the importance of methodological transparency and the development of research agendas. These insights inform all stakeholders involved in the development and publication of review papers.","lang":"eng"}],"department":[{"_id":"277"}],"language":[{"iso":"eng"}],"publication":"Information & Management","file_date_updated":"2020-12-29T11:49:57Z","date_updated":"2022-06-10T06:53:12Z","author":[{"full_name":"Wagner, Gerit","last_name":"Wagner","first_name":"Gerit"},{"last_name":"Prester","first_name":"Julian","full_name":"Prester, Julian"},{"full_name":"Roche, Maria","last_name":"Roche","first_name":"Maria"},{"full_name":"Schryen, Guido","id":"72850","last_name":"Schryen","first_name":"Guido"},{"first_name":"Alexander","last_name":"Benlian","full_name":"Benlian, Alexander"},{"full_name":"Paré, Guy","first_name":"Guy","last_name":"Paré"},{"full_name":"Templier, Mathieu","first_name":"Mathieu","last_name":"Templier"}],"ddc":["000"],"_id":"20844","title":"Which Factors Affect the Scientific Impact of Review Papers in IS Research?

Accounting for the widely acknowledged limitations of pure citation analysis, we adopt a knowledge-based perspective on scientific impact to develop a methodology for content-based citation analysis which allows determining how papers have enabled knowledge development in subsequent research (knowledge impact). As knowledge development differs between research genres, we develop a new knowledgebased citation analysis methodology for the genre of standalone literature reviews (LRs). We apply the suggested methodology to the IS business value domain by manually coding 22 LRs and 1,228 citing papers (CPs) and show that the results challenge the assumption that citations indicate knowledge impact. We derive implications for distinguishing knowledge impact from citation impact in the LR genre. Finally, we develop recommendations for authors of LRs, scientific evaluation committees and editorial boards of journals how to apply and benefit from the suggested methodology, and we discuss its efficiency and automatization."}],"type":"working_paper","file_date_updated":"2020-05-19T15:09:28Z"},{"keyword":["Reading and skimming","Exploring literature","Review methodology","Design science research","Schemata theory"],"file":[{"access_level":"open_access","date_created":"2020-05-24T17:17:32Z","content_type":"application/pdf","file_size":590754,"relation":"main_file","date_updated":"2021-08-13T14:04:55Z","file_name":"2020-03-27-ECIS2020 Designing a novel strategy for exploring literature corpora.pdf","creator":"hsiemes","file_id":"17056"}],"status":"public","date_created":"2020-05-24T15:23:32Z","oa":"1","type":"conference","year":"2020","conference":{"location":"Marrakesh, Morocco","name":"Twenty-Eigth European Conference on Information Systems (ECIS2020)"},"author":[{"full_name":"Wagner, Gerit","last_name":"Wagner","first_name":"Gerit"},{"first_name":"Philipp","last_name":"Empl","full_name":"Empl, Philipp"},{"first_name":"Guido","last_name":"Schryen","id":"72850","full_name":"Schryen, Guido"}],"_id":"17055","ddc":["000"],"title":"Designing a Novel Strategy for Exploring Literature Corpora","citation":{"apa":"Wagner, G., Empl, P., & Schryen, G.

Nevertheless, corresponding guidelines have not been updated for decades. We contend that the traditional strategy of skimming all papers and reading selected papers afterwards needs to be revised. Therefore, we design a new strategy that guides the overall exploratory process by prioritizing influential papers for initial reading, followed by skimming the remaining papers. Consistent with schemata theory, starting with in-depth reading allows readers to acquire more substantial prior content schemata, which are representa-tive for the literature corpus and useful in the following skimming process. To this end, we develop a prototype that identifies the influential papers from a set of PDFs, which is illustrated in a case study in the IT business value domain. With the new strategy, we envision a more efficient process of exploring unknown literature corpora."}],"department":[{"_id":"277"}],"language":[{"iso":"eng"}],"publication":"28th European Conference on Information Systems (ECIS 2020)","file_date_updated":"2021-08-13T14:04:55Z","date_updated":"2022-01-06T06:53:03Z"},{"issue":"9","file":[{"date_updated":"2020-03-05T10:36:48Z","file_size":186658,"relation":"main_file","content_type":"application/pdf","file_id":"15415","file_name":"Bringing HPC to management science - Web version.pdf","creator":"hsiemes","date_created":"2019-12-28T14:30:03Z","access_level":"open_access"}],"status":"public","oa":"1","date_created":"2019-12-28T14:27:44Z","type":"journal_article","year":"2020","intvolume":" 63","page":"35 - 37","author":[{"id":"72850","full_name":"Schryen, Guido","first_name":"Guido","last_name":"Schryen"}],"ddc":["000"],"_id":"15414","volume":63,"title":"Integrating Management Science into the HPC Research Ecosystem","department":[{"_id":"277"}],"language":[{"iso":"eng"}],"citation":{"apa":"Schryen, G.

We regard timing in two dimensions, namely the time of announcement in relation to the time of investment and the time of announcement in relation to the time of a fundamental security incident. The financial value of information security investments is assessed by examining the relationship between the investment announcements and their stock market reaction focusing on the two time dimensions. Using an event study methodology, we found that both dimensions influence the stock market return of the investing organization. Our results indicate that (1) after fundamental security incidents in a given industry, the stock price will react more positively to a firm’s announcement of actual information security investments than to announcements of the intention to invest; (2) the stock price will react more positively to a firm’s announcements of the intention to invest after the fundamental security incident compared to before; and (3) the stock price will react more positively to a firm’s announcements of actual information security investments after the fundamental security incident compared to before. Overall, the lowest abnormal return can be expected when the intention to invest is announced before a fundamental information security incident and the highest return when actual investing after a fundamental information security incident in the respective industry.","lang":"eng"}],"language":[{"iso":"eng"}],"user_id":"61579","citation":{"apa":"Szubartowicz, E., & Schryen, G.

This challenge requires decision makers to assess\r\nwhich system or software packages are prone to vulnerabilities, how many post-release vulnerabilities\r\ncan be expected to occur during a certain period of time, and what impact exploits might have.\r\nSubstantial research has been dedicated to techniques that analyze source code and detect security\r\nvulnerabilities. However, only limited research has focused on forecasting security vulnerabilities\r\nthat are detected and reported after the release of software. To address this shortcoming, we apply\r\nestablished methodologies which are capable of forecasting events exhibiting specific time series\r\ncharacteristics of security vulnerabilities, i.e., rareness of occurrence, volatility, non-stationarity,\r\nand seasonality. Based on a dataset taken from the National Vulnerability Database (NVD), we use\r\nthe Mean Absolute Error (MAE) and Root Mean Square Error (RMSE) to measure the forecasting\r\naccuracy of single, double, and triple exponential smoothing methodologies, Croston's methodology,\r\nARIMA, and a neural network-based approach. We analyze the impact of the applied forecasting\r\nmethodology on the prediction accuracy with regard to its robustness along the dimensions of the\r\nexamined system and software package \"operating systems\", \"browsers\" and \"office solutions\" and\r\nthe applied metrics. To the best of our knowledge, this study is the first to analyze the effect\r\nof forecasting methodologies and to apply metrics that are suitable in this context. Our results\r\nshow that the optimal forecasting methodology depends on the software or system package, as some\r\nmethodologies perform poorly in the context of IT security vulnerabilities, that absolute metrics\r\ncan cover the actual prediction error precisely, and that the prediction accuracy is robust within the\r\ntwo applied forecasting-error metrics.","lang":"eng"}],"publication":"Computers & Security","file_date_updated":"2019-09-09T18:24:35Z","date_updated":"2022-10-19T15:27:51Z"},{"type":"journal_article","oa":"1","date_created":"2018-11-14T15:35:27Z","intvolume":" 272","page":"352 - 363","publisher":"Elsevier","year":"2019","issue":"1","keyword":["OR in disaster relief","disaster operations management","scheduling","branch-and-price"],"status":"public","file":[{"access_level":"open_access","date_created":"2018-12-07T11:13:12Z","creator":"hsiemes","file_name":"JOURNAL VERSION.pdf","file_id":"6019","file_size":1470310,"date_updated":"2018-12-13T15:16:37Z","relation":"main_file","content_type":"application/pdf"}],"file_date_updated":"2018-12-13T15:16:37Z","publication":"European Journal of Operational Research","language":[{"iso":"eng"}],"department":[{"_id":"277"}],"abstract":[{"text":"In disaster operations management, a challenging task for rescue organizations occurs when they have to assign and schedule their rescue units to emerging incidents under time pressure in order to reduce the overall resulting harm. Of particular importance in practical scenarios is the need to consider collaboration of rescue units. This task has hardly been addressed in the literature. We contribute to both modeling and solving this problem by (1) conceptualizing the situation as a type of scheduling problem, (2) modeling it as a binary linear minimization problem, (3) suggesting a branch-and-price algorithm, which can serve as both an exact and heuristic solution procedure, and (4) conducting computational experiments - including a sensitivity analysis of the effects of exogenous model parameters on execution times and objective value improvements over a heuristic suggested in the literature - for different practical disaster scenarios. The results of our computational experiments show that most problem instances of practically feasible size can be solved to optimality within ten minutes. Furthermore, even when our algorithm is terminated once the first feasible solution has been found, this solution is in almost all cases competitive to the optimal solution and substantially better than the solution obtained by the best known algorithm from the literature. This performance of our branch-and-price algorithm enables rescue organizations to apply our procedure in practice, even when the time for decision making is limited to a few minutes.

We address this gap by (1) adapting an exact branch-and-price algorithm to a parallel machine scheduling problem on unrelated machines with sequence- and machine-dependent setup times, (2) parallelizing the adapted algorithm by implementing a distributed-memory parallelization with a master/worker approach, and (3) conducting extensive computational experiments using up to 960 MPI processes on a modern high performance computing cluster. With our experiments, we show that the efficiency of our parallelization approach can lead to superlinear speedup but can vary substantially between instances.

We propose a research model that investigates how different levels of trade-off exposure cognitively and affectively influence consumers’ satisfaction with RAs. We operationalize these levels in three different RA types and test our hypotheses in a laboratory experiment with 116 participants. Our results indicate that with increasing tradeoff exposure, perceived enjoyment and perceived control follow an inverted Ushaped relationship.

The effective coordination of these volunteers is crucial to leverage their capabilities and to avoid conflicts with professional relief units. In this paper, we empirically identify key requirements that professional relief units pose on this coordination. Based on these requirements, we suggest a decision model. We computationally solve a real-world instance of the model and empirically validate the computed solution in interviews with practitioners. Our results show that the suggested model allows for solving volunteer coordination tasks of realistic size near-optimally within short time, with the determined solution being well accepted by practitioners. We also describe in this article how the suggested decision support model is integrated in the volunteer coordination system which we develop in joint cooperation with a disaster management authority and a software development company."}],"language":[{"iso":"eng"}],"department":[{"_id":"277"}],"title":"Decision Support for the Optimal Coordination of Spontaneous Volunteers in Disaster Relief","ddc":["000"],"_id":"5675","author":[{"full_name":"Rauchecker, Gerhard","last_name":"Rauchecker","first_name":"Gerhard"},{"id":"72850","full_name":"Schryen, Guido","last_name":"Schryen","first_name":"Guido"}],"conference":{"name":"15th International Conference on Information Systems for Crisis Response and Management","location":"Rochester, NY, USA"},"year":"2018","type":"conference","date_created":"2018-11-14T15:35:54Z","oa":"1","status":"public","file":[{"date_created":"2018-12-07T11:25:06Z","access_level":"open_access","file_id":"6020","file_name":"2018_ISCRAM_Conference_Proceedings - Publication Version.pdf","creator":"hsiemes","relation":"main_file","date_updated":"2018-12-13T15:05:44Z","file_size":488472,"content_type":"application/pdf"}],"keyword":["Coordination of spontaneous volunteers","volunteer coordination system","decision support","scheduling optimization model","linear programming"]},{"user_id":"61579","has_accepted_license":"1","citation":{"short":"J.

In the presence of budget constraints and a diverse set of assets to protect, organizations have to decide in which IT security measures to invest, how to evaluate those investment decisions, and how to learn from past decisions to optimize future security investment actions. While the academic literature has provided valuable insights into these issues, there is a lack of empirical contributions. To address this lack, we conduct a theory-based exploratory multiple case study. Our case study reveals that (1) firms? investments in information security are largely driven by external environmental and industry-related factors, (2) firms do not implement standardized decision processes, (3) the security process is perceived to impact the business process in a disturbing way, (4) both the implementation of evaluation processes and the application of metrics are hardly existent and (5) learning activities mainly occur at an ad-hoc basis.","lang":"eng"}],"language":[{"iso":"eng"}],"has_accepted_license":"1","citation":{"mla":"Weishäupl, Eva, et al. “Information Security Investments: An Exploratory Multiple Case Study on Decision-Making, Evaluation and Learning.” Computers & Security, vol. 77, Elsevier, 2018, pp. 807–23.","ama":"Weishäupl E, Yasasin E, Schryen G.

We prove that an MmS allocation does not need to exist for chores and computing an MmS allocation - if it exists - is strongly NP-hard. In view of these non-existence and complexity results, we present a polynomial-time 2-approximation algorithm for MmS fairness for chores. We then introduce a new fairness concept called optimal MmS that represents the best possible allocation in terms of MmS that is guaranteed to exist. We use connections to parallel machine scheduling to give (1) a polynomial-time approximation scheme for computing an optimal MmS allocation when the number of agents is fixed and (2) an effective and efficient heuristic with an ex-post worst-case analysis.","lang":"eng"}],"citation":{"bibtex":"@inproceedings{Aziz_Rauchecker_Schryen_Walsh_2017, title={Algorithms for Max-Min Share Fair Allocation of Indivisible Chores}, volume={31}, number={1}, booktitle={Thirty-First AAAI Conference on Artificial Intelligence (AAAI-17)}, author={Aziz, Haris and Rauchecker, Gerhard and Schryen, Guido and Walsh, Toby}, year={2017}, pages={1–7} }","mla":"Aziz, Haris, et al. “Algorithms for Max-Min Share Fair Allocation of Indivisible Chores.” Thirty-First AAAI Conference on Artificial Intelligence (AAAI-17), vol. 31, no. 1, 2017, pp. 1–7.","chicago":"Aziz, Haris, Gerhard Rauchecker, Guido Schryen, and Toby Walsh. “Algorithms for Max-Min Share Fair Allocation of Indivisible Chores.” In Thirty-First AAAI Conference on Artificial Intelligence (AAAI-17), 31:1–7, 2017.","ieee":"H.

While ongoing debates address the relative importance of design science contributions in the information systems community, insights into the scientific impact of design science research (DSR) are missing and this lack of understanding arguably poses challenges to an informed discourse. To identify the most influential papers and those factors that explain their scientific impact, this paper presents an exploratory study of the scientific impact of DSR papers published in the AIS Senior Scholars' Basket of Journals. We uncover the current DSR landscape by taking stock of influential papers and theories and develop a model to explain the scientific impact of DSR papers. Our findings show that scientific impact is significantly explained by theorization and novelty. We discuss how the implications of our work can be projected on the overarching discourse on DSR."}],"department":[{"_id":"277"}],"publication":"38th International Conference on Information Systems","file_date_updated":"2018-12-13T15:07:05Z","extern":"1","date_updated":"2022-01-06T07:02:05Z","license":"https://creativecommons.org/licenses/by-sa/4.0/","status":"public","file":[{"file_size":223790,"date_updated":"2018-12-13T15:07:05Z","relation":"main_file","content_type":"application/pdf","file_id":"6026","file_name":"ICIS2017-Revision.pdf","creator":"hsiemes","date_created":"2018-12-07T11:31:37Z","access_level":"open_access"}],"date_created":"2018-11-14T11:33:56Z","oa":"1","type":"conference","year":"2017","conference":{"name":"38th International Conference on Information Systems","location":"Seoul, South Korea"}},{"title":"High-Performance Business Computing - Effizienzsteigerung durch Parallelisierung","status":"public","author":[{"last_name":"Schryen","first_name":"Guido","full_name":"Schryen, Guido","id":"72850"},{"full_name":"Hristova, Diana","last_name":"Hristova","first_name":"Diana"}],"_id":"5626","year":"2017","extern":"1","date_updated":"2022-01-06T07:02:13Z","citation":{"apa":"Schryen, G., & Hristova, D.

However, as we argue in this paper, existing MAVT-based methods for measuring attribute importance weights do not fit the shopping tasks for which recommender systems are typically used. These methods assume well-trained decision makers who are willing to invest time and cognitive effort, and who are familiar with the attributes describing the available alternatives and the ranges of these attribute levels. Yet, recommender systems are most often used by consumers who are usually not familiar with the available attributes and ranges and who wish to save time and effort. Against this background, we develop a new method, based on a product configuration process, which is tailored to the characteristics of these particular decision makers. We empirically compare our method to SWING, ranking-based conjoint analysis and TRADEOFF in a between-subjects laboratory experiment with 153 participants. Results indicate that our proposed method performs better than TRADEOFF and CONJOINT and at least as well as SWING in terms of recommendation accuracy, better than SWING and TRADEOFF and at least as well as CONJOINT in terms of cognitive load, and that participants were faster with our method than with any other method.

Recent advances in artificial-intelligence based attacks show that the level of security provided by many state-of-the-art text-based CAPTCHAs is declining. At the same time, techniques for distorting and obscuring the text, which are used to maintain the level of security, make text-based CAPTCHAs diffcult to solve for humans, and thereby further degrade usability. The need for developing alternative types of CAPTCHAs which improve both, the current security and usability levels, has been emphasized by several researchers. With this study, we contribute to research through (1) the development of two new face recognition CAPTCHAs (Farett-Gender and Farett-Gender&Age), (2) the security analysis of both procedures, and (3) the provision of empirical evidence that one of the suggested CAPTCHAs (Farett-Gender) is similar to Google's reCAPTCHA and better than KCAPTCHA concerning effectiveness (error rates), superior to both regarding learnability and satisfaction but not effciency.","lang":"eng"}],"department":[{"_id":"277"}],"citation":{"bibtex":"@article{Schryen_Wagner_Schlegel_2016, title={Development of two novel face-recognition CAPTCHAs: a security and usability study}, volume={60}, number={July}, journal={Computers & Security}, publisher={Elsevier}, author={Schryen, Guido and Wagner, Gerit and Schlegel, Alexander}, year={2016}, pages={95–116} }","ama":"Schryen G, Wagner G, Schlegel A.

Since many scheduling problems are NP-hard in the strong sense, there is a need for developing solution heuristics. For scheduling problems with setup times on unrelated parallel machines, there is limited research on solution methods and to the best of our knowledge, parallel computer architectures have not yet been taken advantage of. We address this gap by proposing and implementing a new solution heuristic and by testing different parallelization strategies. In our computational experiments, we show that our heuristic calculates near-optimal solutions even for large instances and that computing time can be reduced substantially by our parallelization approach."}],"language":[{"iso":"eng"}],"status":"public","file":[{"file_id":"6031","creator":"hsiemes","file_name":"ACIS_2015_paper_7.pdf","content_type":"application/pdf","date_updated":"2018-12-13T15:08:28Z","file_size":6771871,"relation":"main_file","date_created":"2018-12-07T11:40:18Z","access_level":"open_access"}],"keyword":["scheduling","decision support","heuristic","high performance computing","parallel algorithms"],"page":"1-13","year":"2015","type":"conference","date_created":"2018-11-14T15:39:50Z","oa":"1"},{"status":"public","file":[{"access_level":"open_access","date_created":"2018-12-07T11:44:10Z","file_name":"ELSEVIER_JOURNAL_VERSION.pdf","creator":"hsiemes","file_id":"6036","content_type":"application/pdf","relation":"main_file","date_updated":"2018-12-13T15:09:12Z","file_size":1270024}],"issue":"2","keyword":["admission control","informational uncertainty","revenue management","cloud computing"],"page":"637-647","intvolume":" 244","publisher":"Elsevier","year":"2015","type":"journal_article","oa":"1","date_created":"2018-11-14T15:40:13Z","volume":244,"title":"Revenue Management for Cloud Computing Providers: Decision Models for Service Admission Control under Non-probabilistic Uncertainty","ddc":["000"],"_id":"5679","author":[{"full_name":"Püschel, Tim","first_name":"Tim","last_name":"Püschel"},{"full_name":"Schryen, Guido","id":"72850","first_name":"Guido","last_name":"Schryen"},{"first_name":"Diana","last_name":"Hristova","full_name":"Hristova, Diana"},{"first_name":"Dirk","last_name":"Neumann","full_name":"Neumann, Dirk"}],"date_updated":"2022-01-06T07:02:30Z","extern":"1","file_date_updated":"2018-12-13T15:09:12Z","publication":"European Journal of Operational Research","department":[{"_id":"277"}],"language":[{"iso":"eng"}],"abstract":[{"lang":"eng","text":"Cloud computing promises the flexible delivery of computing services in a pay-as-you-go manner. It allows customers to easily scale their infrastructure and save on the overall cost of operation. However Cloud service offerings can only thrive if customers are satisfied with service performance. Allow-ing instantaneous access and flexible scaling while maintaining the service levels and offering competitive prices poses a significant challenge to Cloud Computing providers. Furthermore services will remain available in the long run only if this business generates a stable revenue stream. To address these challenges we introduce novel policy-based service admission control mod-els that aim at maximizing the revenue of Cloud providers while taking in-formational uncertainty regarding resource requirements into account. Our evaluation shows that policy-based approaches statistically significantly out-perform first come first serve approaches, which are still state of the art. Furthermore the results give insights in how and to what extent uncertainty has a negative impact on revenue."}],"user_id":"61579","has_accepted_license":"1","citation":{"short":"T. Püschel, G.
