Collaboration Support Through Mobile Processes and Entailment Constraints

Abstract

Abstract-The computational capability of smart mobile devices increasingly fosters their prevalence in many business domains. Along this trend, process management technology is going to be enhanced with mobile task support. However, tasks executed stationarily so far cannot be simply transfered to mobile devices. For the latter purpose, we developed an approach within the MARPLE project enabling mobile and robust task execution in the context of business processes. In particular, this approach provides self-healing techniques that relieve mobile users from manually handling errors (e.g., lost connections) during mobile task execution. In this paper, we extend the collaboration facilities of our approach by adding entailment constraints to mobile task management. In the context of a business process, for example, two tasks may have to be executed by the same (mobile) user. Related research on integrating such constraints with business processes has received growing attention recently. However, realizing entailment constraints in the context of mobile processes and tasks raises additional issues, which must be probably integrated with the mentioned error handling techniques. We present fundamental entailment constraints supported by our approach and discuss how they can be realized in a robust and flexible manner. In particular, this will significantly enhance mobile task and process support in next generation information systems.

Location-based Mobile Augmented Reality Applications - Challenges, Examples, Lessons Learned

“…Finally, research on business process management offers flexible concepts, which are useful for enabling proper exception handling in the context of mobile applications as well (Pryss et al, 2012;Pryss et al, 2013;Pryss et al, 2010). Since mobile augmented reality applications may cause various errors (e.g., sensor data is missing), adopting these concepts is promising.…”

Context-Based Handling of Mobile Process Activities

“…It is denoted as Selection Algorithm, meaning that all mobile users determined by the algorithm are qualified to execute the mobile activity. The qualification, in turn, is based on three concepts: authorization (e.g., roles (Sandhu et al, 1996)), constraints; e.g., to ensure two activities will be executed by the same user (Pryss, Musiol, & Reichert, 2013), and a mobile context (see Fig. 3, 4).…”

“…Thereby, they may either assign these rights in the context of a particular process instance or for all process instances. (Schaad, 2003;Crampton & Khambhammettu, 2008;Gaaloul & Charoy, 2009) provide various reasons for delegating respective rights; e.g., a user may not possess required documents, or an entailment constraint like separation of duties must be enforced (Pryss, Musiol, & Reichert, 2013). In this context, delegation may be accomplished based on two techniques: First, delegation may be applied based on user-defined rules stored in a repository.…”
