Run-Time Variability for Context-Aware Smart Workflows

In variant-rich workflow-based systems, a major concern for process variability is the context-aware configuration of the variants. This means that context information, not users, drives process configuration. To support context-aware process configuration in a dynamic environment, in which context information is available only at run time, smart workflows must be customized at run time. The LateVa (Late Variability for Context-Aware Smart Workflows) framework lets developers model and manage process variability by composing base models, fragments, and variability models and by deferring binding to run time. Base models and fragments are reusable, thereby reducing the modeling effort for developing variants. LateVa also includes an automated run-time-variability mechanism for context-aware smart workflows.
