Clinical Processes – The Killer Application for Constraint-Based Process Interactions?

Abstract. For more than a decade, the interest in aligning information
systems in a process-oriented way has been increasing. To enable operational support for business processes, the latter are usually specified in
an imperative way. The resulting process models, however, tend to be too
rigid to meet the flexibility demands of the actors involved. Declarative
process modeling languages, in turn, provide a promising alternative in
scenarios in which a high level of flexibility is demanded. In the scientific
literature, declarative languages have been used for modeling rather simple processes or synthetic examples. However, to the best of our knowledge, they have not been used to model complex, real-world scenarios
that comprise constraints going beyond control-flow. In this paper, we
propose the use of a declarative language for modeling a sophisticated
healthcare process scenario from the real world. The scenario is subject to
complex temporal constraints and entails the need for coordinating the
constraint-based interactions among the processes related to a patient
treatment process. As demonstrated in this work, the selected real process scenario can be suitably modeled through a declarative approach.

Towards a new Tool for Managing Declarative Temporal Business Process Models

Business processes which require a high flexibility are com- monly specified in a declarative (e.g., constraint-based) way. In general, offering operational support (e.g., generating possible execution traces) to declarative business process models entails more complexity when compared to imperative modeling alternatives. Such support becomes even more complex in many real scenarios where the management of complex temporal relations between the process activities is crucial (i.e., the temporal perspective should be managed). Despite the needs for enabling process flexibility and dealing with temporal constraints, most existing tools are unable to manage both. In a previous work, we then proposed TConDec-R, which is a constraint-based process modeling lan- guage which allows for the specification of temporal constraints. In this paper we introduce the basis and a prototype of a constraint-based tool with a client/server architecture for providing operational support to TConDec-R process models.
