Abstract

Workflow time management deals with the calculation of temporal thresholds for process activities, which allows forecasts about looming deadline violations. We present a novel approach to transform a web service orchestration into a time-aware orchestration, that contains temporal assessment and intervention logic. During process execution intervention strategies are triggered pro-actively to speed up a late process and to avoid upcoming violations of temporal constraints.
