Automatic Generation of Questionnaires for Supporting Users during the Execution of Declarative Business Process Models

Abstract

When designing an imperative business process (BP) model, analysts have to face many design requirements (e.g., managing uncertainty, optimizing conflicting objective functions). To facilitate such design, declarative BP models are increasingly used. However, how to execute a given declarative model can be quite challenging since there are typically several variants related to such model, each one presenting different degree of goodness. To support users working on declarative models while a high flexibility is maintained, we propose removing the worst variants from the source declarative model at design time while keeping the best variants. This way, the variants which are kept are narrowed down incrementally during run-time. For managing these variants during run-time we suggest to build upon configurable BP models. To configure such models, we additionally propose to automatically generate questionnaires. The results over a real case study are promising.
