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.","lang":"eng"}],"status":"public","file":[{"content_type":"application/pdf","relation":"main_file","date_updated":"2018-12-13T15:08:28Z","date_created":"2018-12-07T11:40:18Z","creator":"hsiemes","file_size":6771871,"access_level":"open_access","file_name":"ACIS_2015_paper_7.pdf","file_id":"6031"}]},{"keyword":["admission control","informational uncertainty","revenue management","cloud computing"],"ddc":["000"],"language":[{"iso":"eng"}],"publication":"European Journal of Operational Research","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."}],"file":[{"file_name":"ELSEVIER_JOURNAL_VERSION.pdf","file_id":"6036","access_level":"open_access","file_size":1270024,"creator":"hsiemes","date_created":"2018-12-07T11:44:10Z","date_updated":"2018-12-13T15:09:12Z","relation":"main_file","content_type":"application/pdf"}],"publisher":"Elsevier","date_created":"2018-11-14T15:40:13Z","title":"Revenue Management for Cloud Computing Providers: Decision Models for Service Admission Control under Non-probabilistic Uncertainty","issue":"2","year":"2015","_id":"5679","department":[{"_id":"277"}],"user_id":"61579","file_date_updated":"2018-12-13T15:09:12Z","extern":"1","type":"journal_article","status":"public","date_updated":"2022-01-06T07:02:30Z","oa":"1","volume":244,"author":[{"full_name":"Püschel, Tim","last_name":"Püschel","first_name":"Tim"},{"full_name":"Schryen, Guido","id":"72850","last_name":"Schryen","first_name":"Guido"},{"first_name":"Diana","full_name":"Hristova, Diana","last_name":"Hristova"},{"last_name":"Neumann","full_name":"Neumann, Dirk","first_name":"Dirk"}],"has_accepted_license":"1","intvolume":"       244","page":"637-647","citation":{"bibtex":"@article{Püschel_Schryen_Hristova_Neumann_2015, title={Revenue Management for Cloud Computing Providers: Decision Models for Service Admission Control under Non-probabilistic Uncertainty}, volume={244}, number={2}, journal={European Journal of Operational Research}, publisher={Elsevier}, author={Püschel, Tim and Schryen, Guido and Hristova, Diana and Neumann, Dirk}, year={2015}, pages={637–647} }","mla":"Püschel, Tim, et al. “Revenue Management for Cloud Computing Providers: Decision Models for Service Admission Control under Non-Probabilistic Uncertainty.” <i>European Journal of Operational Research</i>, vol. 244, no. 2, Elsevier, 2015, pp. 637–47.","short":"T.

While research on IT security investment is fast growing, it lacks a theoretical basis for structuring research, explaining economic-technological phenomena and guide future research. We address this shortcoming by suggesting a new theoretical model emerging from a multi-theoretical perspective adopt-ing the Resource-Based View and the Organizational Learning Theory. The joint appli-cation of these theories allows to conceptualize in one theoretical model the organiza-tional learning effects that occur when the protection of organizational resources through IT security countermeasures develops over time. We use this model of IT security invest-ments to synthesize findings of a large body of literature and to derive research gaps.

However, it is a challenging task to assign access rights to employees? accounts within a satisfying time frame. In addition, the management of multiple accounts and identities can be very onerous and time consuming for the responsible administrator and therefore expensive for the organization. In order to meet these challenges, firms decide to invest in introducing an Identity and Access Management System (IAMS) that supports the organization by using policies to assign permissions to accounts, groups, and roles. In practice, since various versions of IAMSs exist, it is a challenging task to decide upon introduction of an IAMS. The following study proposes a first attempt of a decision support model for practitioners which considers four alternatives: Introduction of an IAMS with Role-based Access Control RBAC) or without and no introduction of IAMS again with or without RBAC. To underpin the practical applicability of the proposed model, we parametrize and operationalize it based on a real world use case using input from an expert interview."}],"status":"public","file":[{"creator":"hsiemes","date_created":"2018-12-07T11:46:28Z","date_updated":"2018-12-13T15:09:54Z","access_level":"open_access","file_id":"6040","file_name":"Towards an Economic Approach to IAMS.PDF","file_size":166015,"content_type":"application/pdf","relation":"main_file"}],"publication":"2nd International Workshop on Security in highly connected IT Systems (SHCIS?15)","type":"conference","keyword":["Identity and Access Management","Economic Decision Making","Information Systems","Information Security Investment","Decision Theory"],"ddc":["000"],"extern":"1","file_date_updated":"2018-12-13T15:09:54Z","language":[{"iso":"eng"}],"_id":"5590","department":[{"_id":"277"}],"user_id":"61579","year":"2015","citation":{"short":"E.

Yet, we observe a lack of theoretical underpinning of and epistemological insights into how literature reviews can contribute to knowledge creation and have actually contributed in the IS discipline. To address these theoretical and empirical research gaps, we suggest a novel epistemological model of literature reviews. This model allows us to align different contributions of literature reviews with their underlying knowledge conversions - thereby building a bridge between the previously largely unconnected fields of literature reviews and epistemology. We evaluate the appropriateness of the model by conducting an empirical analysis of 173 IS literature reviews which were published in 39 pertinent IS journals between 2000 and 2014. Based on this analysis, we derive an epistemological taxonomy of IS literature reviews, which complements previously suggested typologies.","lang":"eng"}],"status":"public","file":[{"content_type":"application/pdf","relation":"main_file","date_created":"2018-12-07T11:44:48Z","creator":"hsiemes","date_updated":"2018-12-13T15:09:22Z","file_id":"6037","file_name":"ICIS PROCEEDINGS PAPER - Literature Reviews.pdf","access_level":"open_access","file_size":487102}]},{"issue":"4","has_accepted_license":"1","page":"243-259","intvolume":"        57","citation":{"ama":"Schryen G, Rauchecker G, Comes M.

In their efforts to take countermeasures against the threats posed by future natural disasters, the United Nations formulated the ?Hyogo Framework for Action?, which aims at assessing and reducing risk. This framework and a global review of disaster reduction initiatives of the United Nations acknowledge the need for information systems research contributions in addressing major challenges of natural disaster management. In this paper, we provide a review of the literature with regard to how information systems research has addressed risk assessment and reduction in natural disaster management. Based on the review we identify research gaps that are centered around the need for acquiring general knowledge on how to design IS artifacts for risk assessment and reduction. In order to close these gaps in further research, we develop a research agenda that follows the IS design science paradigm.","lang":"eng"}],"file":[{"relation":"main_file","content_type":"application/pdf","access_level":"open_access","file_id":"6044","file_name":"Risk reduction in NDM - Revision 1.pdf","file_size":2708161,"creator":"hsiemes","date_created":"2018-12-07T11:50:26Z","date_updated":"2018-12-13T15:11:05Z"}],"keyword":["Natural Disaster Management","Risk Reduction","Hyogo Framework","IS Design Science","Literature review"],"ddc":["000"],"language":[{"iso":"eng"}],"issue":"1","year":"2014","date_created":"2018-11-14T13:58:50Z","title":"Risk Reduction in Natural Disaster Management Through Information Systems: A Literature review and an IS design science research agenda"},{"oa":"1","date_updated":"2022-01-06T07:02:13Z","volume":37,"author":[{"first_name":"Guido","full_name":"Schryen, Guido","id":"72850","last_name":"Schryen"},{"first_name":"Diana","full_name":"Hristova, Diana","last_name":"Hristova"}],"has_accepted_license":"1","page":"1-48","intvolume":"        37","citation":{"ieee":"G.
