With increasing storage demands and emerging storage services the question how to schedule storage jobs becomes more and more interesting. Since such scheduling problems are often in the class NP-complete an exact computation is not feasible in practice. On the other hand an approximation to the optimal solution can easily be found by means of using heuristics. The problem with this attempt is that the suggested solution may not be exactly optimal and is thus less satisfying. Considering the two above mentioned solution approaches one can clearly find a trade-off between the optimality of the solution and the efficiency to get to a solution at all. This work proposes to apply and combine heuristics in optimization to gain from both of their benefits while reducing the problematic aspects. Following this method it is assumed to get closer to the optimal solution in a shorter time compared to a full optimization."}],"extern":"1","publication":"18th European Conference on Information Systems (ECIS 2010)"},{"author":[{"full_name":"Bodenstein, Christian","first_name":"Christian","last_name":"Bodenstein"},{"id":"72850","full_name":"Schryen, Guido","last_name":"Schryen","first_name":"Guido"},{"full_name":"Neumann, Dirk","last_name":"Neumann","first_name":"Dirk"}],"title":"From \"Take-it-or-leave-it\" offers to \"Take-it-or-be-left-out\" Ultimatum - A trade mechanism for Online Services","year":"2010","date_updated":"2022-01-06T07:02:34Z","language":[{"iso":"eng"}],"publication":"18th European Conference on Information Systems (ECIS 2010)","extern":"1","abstract":[{"text":"In a world, where more and more businesses seem to trade in an online market, the supply of online services to supply the ever-growing demand could quickly reach its capacity limits. Online service providers may find themselves maxed out at peak operation levels during high-traffic timeslots but too little demand during low-traffic timeslots, although the latter is becoming less frequent. At this point not only deciding which user is allocated what level of service becomes essential, but also the magnitude of the service provided, can be controlled by pricing. Pricing is an important factor when efficient and acceptable allocation of resources between individuals must be reached. Without prices, transferring or sharing goods would be impossible. In sharing information, pricing a product however is not as simple as relatively pricing an apple or a pear. Often the costs, and hence the prices are simply unknown. Backed by this scenario, the online services market could be combined with the market design mechanism of diamonds. For this we propose an ultimatum pricing strategy which effectively allows for valuations to be accounted for, but no longer a necessity when pricing in grid, cloud or other online computing environments.","lang":"eng"}],"date_created":"2018-11-14T15:48:39Z","file":[{"creator":"hsiemes","date_created":"2018-12-11T15:22:41Z","date_updated":"2018-12-13T15:20:13Z","relation":"main_file","access_level":"open_access","file_size":247621,"file_name":"Take it or leave it - ECIS - Proof.pdf","content_type":"application/pdf","file_id":"6191"}],"department":[{"_id":"277"}],"keyword":["Posted Price","Ultimatum Game","Energy Efficiency","Mechanism Design"],"type":"conference","status":"public","has_accepted_license":"1","_id":"5690","user_id":"61579","ddc":["000"],"citation":{"mla":"Bodenstein, Christian, et al. “From ‘Take-It-or-Leave-It’ Offers to ‘Take-It-or-Be-Left-out’ Ultimatum - A Trade Mechanism for Online Services.” <i>18th European Conference on Information Systems (ECIS 2010)</i>, 2010.","ama":"Bodenstein C, Schryen G, Neumann D.

This paper assumes that literature reviews, which represent a powerful instrument for the identification and synthesis of knowledge, have not tapped their full potential to address this issue due to deficiencies in methodology. The analysis of 18 literature reviews published in pertinent academic outlets during the past 20 years shows such deficiencies. Two of the most critical weaknesses identified are (1) the lack of theory use in most reviews and (2) a weak linkage of reviews, resulting in little progress in theory and framework development. The systematic identification of these weaknesses and the extraction of promising methodological examples from past literature are the main contributions of this work, which supports the composition of more effective literature reviews in future research.","lang":"eng"}],"publication":"Proceedings of the First Scandinavian Conference on Information Systems (SCIS)","keyword":["Literature review","Business value","Information systems","Methodology","Theory"],"type":"conference","department":[{"_id":"277"}],"file":[{"content_type":"application/pdf","file_id":"6186","date_updated":"2018-12-13T15:17:00Z","relation":"main_file","access_level":"open_access","file_size":302340,"file_name":"2010_Book_ScandinavianInformationSystems - Schryen.pdf","date_created":"2018-12-11T15:14:51Z","creator":"hsiemes"}],"date_created":"2018-11-14T14:36:26Z"},{"year":"2010","title":"Preserving knowledge on IS business value: what literature reviews have done","author":[{"id":"72850","full_name":"Schryen, Guido","last_name":"Schryen","first_name":"Guido"}],"date_updated":"2022-01-06T07:02:19Z","intvolume":"        52","language":[{"iso":"eng"}],"issue":"4","publication":"Business \\& Information Systems Engineering (BISE)","extern":"1","abstract":[{"text":"The economic relevance of information systems has been studied for many years and has attracted an abundance of research papers. However, the ?productivity paradoxon? of the 90s, Carr?s widely recognized paper ?IT doesn?t matter?, and several studies that do not find a positive correlation between IS investments and economic performance reveal long-lasting difficulties for IS researchers to explain ?IS business value?. Business executives and researchers also continue to question the value of IS investments. This raises the question of whether literature reviews have tapped their potential to address the concerns by covering key research areas of IS business value and preserving their key findings. In order to address this question, this paper identifies and describes 12 key research areas, and synthesizes what literature reviews published in pertinent academic outlets have done to preserve knowledge. The analysis of 22 literature reviews shows that some crucial areas have not been (sufficiently) covered. They provide fertile areas for future literature reviews. As this work is based on the results of more than 200 research papers, it is capable of drawing a comprehensive picture of the current state-of-the-art in IS business value research.","lang":"eng"}],"file":[{"content_type":"application/pdf","file_id":"6187","date_updated":"2018-12-13T15:17:12Z","relation":"main_file","file_size":525443,"access_level":"open_access","file_name":"BISE-PreservingknowledgeonISbusinessvalue-Manuscript-1.pdf","date_created":"2018-12-11T15:19:37Z","creator":"hsiemes"}],"date_created":"2018-11-14T14:38:02Z","type":"journal_article","keyword":["Business value","Information systems","Literature review","Meta review"],"department":[{"_id":"277"}],"status":"public","has_accepted_license":"1","page":"225-237","_id":"5644","publisher":"Springer","user_id":"61579","ddc":["000"],"volume":52,"file_date_updated":"2018-12-13T15:17:12Z","citation":{"mla":"Schryen, Guido. “Preserving Knowledge on IS Business Value: What Literature Reviews Have Done.” <i>Business \\&#38; Information Systems Engineering (BISE)</i>, vol. 52, no. 4, Springer, 2010, pp. 225–37.","bibtex":"@article{Schryen_2010, title={Preserving knowledge on IS business value: what literature reviews have done}, volume={52}, number={4}, journal={Business \\&#38; Information Systems Engineering (BISE)}, publisher={Springer}, author={Schryen, Guido}, year={2010}, pages={225–237} }","ama":"Schryen G.
