Service selection in mobile environments: considering multiple users and context-awareness

Abstract

In mobile environments, users often need to coordinate their actions with other users with regard to user-individual context information like current location when selecting suitable services for a process. Thereby, some users may prefer to conduct particular services together with certain other users. Such multi-user context-aware service selections could result in complex decision problems – making decision support for the participating users highly valuable or even necessary. To do so, we propose an optimisation-based service selection approach for multi-user context-aware processes. We also show how our approach provides decision support by evaluating its efficacy based on a real-world scenario.

Automated planning of process models: The construction of parallel splits and synchronizations

“…For instance, the process models constructed by our approach can be used by service selection approaches. This means, planned process models including different feasible parallelizations can be assessed regarding both their potential service implementation and resulting Qualityof-service values (e.g., overall cost or availability) which supports to choose beneficial execution routes (cf., e.g., [17,71]).…”
