Declarative Modelling and Safe Distribution of Healthcare Workflows

We present a formal technique for safe distribution of workflow processes described declaratively as Nested Condition Response (NCR) Graphs and apply the technique to a distributed healthcare workflow. Concretely, we provide a method to synthesize from an NCR Graph and any distribution of its events a set of local process graphs communicating by shared events, such that the distributed execution of the local processes is equivalent to executing the original process. The technique is based on our recent similar work on safe distribution of Dynamic Condition Response (DCR) Graphs applied to cross-organizational case management. The contributions of this paper is to adapt the technique to allow for nested processes and milestones and to apply it to a healthcare workflow identified in a previous field study at danish hospitals.
