Technique for Optimal Adaptation of Time-Dependent Workflows with Security Constraints

Distributed workflow based systems are widely used in various application domains including e-commerce, digital government, healthcare, manufacturing and many others. Workflows in these application domains are not restricted to the administrative boundaries of a single organization [1]. The tasks in a workflow need to be performed in a certain order and often times are subject to temporal constraints and dependencies [1, 2]. A key requirement for such workflow applications is to provide the right data to the right person at the right time. This requirement motivates for dynamic adaptations of workflows for dealing with changing environmental conditions and exceptions.
