A novel flexible activity refinement approach for improving workflow process flexibility

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

“…We exclude works that are not related to business processes, view temporal constraints solely in the sense of ordering relations, or only mention temporal constraints at an abstract level (i.e., no specific temporal constraints are discussed). In the end, several papers [20,9,16,17,15,32,10,4,26,2,18] were identified as relevant works in the context of our research.…”

Respective process models are denoted as constraint-based, i.e., they comprise information about (1) the activities that may be performed during process enactment as well as (2) the constraints to be obeyed in this context.…”

“…Although there exists related work on declarative BP modeling [28,31,20,9,17,10,4], only few approaches pay attention to the temporal perspective from a wider point of view, i.e., beyond viewing temporal constraints solely just in the sense of ordering relations [20,9,17,16,32,15,26,10,4]. To assess to what extent these works may support the temporal constraints required by the considered scenario, we performed a review which revealed that there exists other works that partially addresses some of the requirements related to the time patterns (i.e., activity durations and time lags between activities).…”

“…Additionally, to provide a validation of the language, a web-based tool has been implemented to support the TConDec-R. 10 Such a tool allows both (1) modeling the clinical scenario of this work as well as other scenarios which require constraints related to the TPs [13], and (2) providing support for generating valid execution traces according to the modeled scenario. The latter has been conducted based on previous work [11,2].…”

“…Declarative approaches are becoming increasingly popular for modeling business processes as they are able to cope with some of the limitations imperative notations are facing [28,31,20,9,17,10,4]. Although declarative modeling languages have been extensively discussed in literature [19,5], even in the context of healthcare [29,21,25], to the best of our knowledge, they have not been used to model complex, real-world scenarios that comprise constraints going beyond control-flow.…”
