ICS – Paper Presentation @ IEEE SCC 2021

From 05.-11. September 2021, the IEEE International Conference on Services Computing (IEEE SCC 2021) will take place as a virtual event. Franziska Selina Hollauf, BSc, who is working at the ICS team from O.Univ.-Prof. Dipl.-Ing. Dr. Johann Eder, will present the paper “Towards Representing Time-Cost Tradeoffs for Service Compositions”.

The paper elaborates the bachelor thesis from Ms. Hollauf and is written by Franziska S. Hollauf, BSc, Dipl.-Ing. Dr. Marco Francheschetti and O.Univ.-Prof. Dipl-Ing. Dr. Johann Eder.


Towards Representing Time-Cost Tradeoffs for Service Compositions


“Service Level Agreements have to contain the time

and cost of using a service. We propose time-cost tables for

representing the relationship between time and cost. Basically

there can be a direct or indirect correlation between duration

and cost of a service. We introduce algorithms for computing

the time-cost relationship of services composed as an orchestration

of other services. These services may have directly and

indirectly proportional cost with respect to time resulting in

more complex relationships between duration and cost. These

representations allow to infer the minimum cost of a service

given temporal constraints, or for checking which durations are

affordable for an available budget. The time-cost tables thus

offer a basis for various optimization of composed services.”
