The 34rd International Conference on Advanced Information Systems Engineering (CAiSE) was organized in Leuven, Belgium by the KU Leuven and the University of Ghent from June 5-10, 2022.

Franziska Hollauf, BSc. presented the paper Time-Cost Tradeoffs for Composed Services. A video recording of the presentation is available here:

Abstract

Time and cost are crucial criteria in Service Level Agreements. Frequently, the time when and how long a service can be provided or used and the cost for utilizing a service are related and hence users are confronted with a trade-off between time and cost. Besides the fundamental direct and indirect proportional relationship between time and cost, composed services might also have more complex non-monotonic relationships. We introduce a novel way of expressing the trade-offs between time and cost in form of TC-Maps as a set of piece-wise linear functions. For calculating the duration, cost and their relation for service compositions, we introduce specific operations used in a bottom-up procedure resulting in an overall TC-Map. The proposed structure allows us to derive the minimum cost of a composed service given a duration limit, or for analyzing possible durations for a provided budget. TC-Maps offer the basis for optimizing the utilization of composed services according to user preferences, resources and objectives.

Two research teams from the University of Klagenfurt remain in the running to be “Clusters of Excellence”

As recently announced by the Austrian Science Fund FWF, eleven teams have reached the final stage of selection for “Cluster of Excellence” funding. The decisions on Austria’s future beacons of basic research will be made in early 2023. The eleven consortia include the “Multi-drone Systems” cluster initiated and led by the University of Klagenfurt, as well as the “Bilateral Artificial Intelligence” project, which feature scientists from Klagenfurt on their Board of Directors.

ICS @ Lange Nacht der Forschung 2022

We were happy to take part in this significant scientific event and had our station at the University of Klagenfurt with the following contribution:

Right timing: will it all work out?
Time constraints like deadlines are part of almost every task. When business processes are automated, it is essential that all procedures can be processed successively on time. We show a tool that improves operations planning and how it can also give feedback: “That’s not possible!” At our station, you can solve a time problem yourself in the form of a quiz!
