Nikolay Borissov, Benjamin Blau, Dirk Neumann · Journal of the Association for Information Systems · 2008
Although the amount of offered Web services is continuously increasing and the Internet of products shifts more and more towards an Internet of services there is still a big lack of efficient service allocation and price determination.Currently, services are mostly charged as flat fees and pay-peruse prices.Albeit static pricing is the most common pricing scheme, dynamic and decentralized service environment requires highly adaptable mechanism for allocation and price determination.As the state and context of services change rapidly prices and allocations are continuously fluctuating.The contribution of this paper is fourfold.Firstly, we introduce three business scenarios for trading web-based services.Secondly, we analyze design requirements for semi-automated trading of web services.Thirdly, we propose and define a model approach for trading Internet services.Finally, using this model, we specify bid extensions for common resource and service description languages.We evaluate our model by analyzing the introduced concepts and giving examples using the specified bidding language.We ran a simulation with the implemented prototype showing the appliance and flexibility of the model.
