International audienceContext-oriented systems are systems that observe and handle context information from the environment to guide their own behavior. Engineering such systems represents a complex task not only due to their complexity, but also due to the notion of context. Handling this notion involves tackling several challenges, demanding to system designers a certain knowledge and expertise about this notion. In order to help designers on this engineering process, we propose in this paper a roadmap on context management and a requirements elicitation process. This roadmap aims at sharing with non-expert designers the necessary expertise on context management allowing them to better understand the notion of context and its challenges. The elicitation process aims at guiding these non-expert designers across the roadmap, supporting them in their requirements elicitation process concerning context management. The proposal is presented on a running example that illustrates the approach

Abstract-Context: Organizations act in highly competitive markets, which forces them to be flexible. Constantly changing business requirements require flexible business processes. Case Management Model and Notation (CMMN) supports modeling run-time flexibility of partially structured business process models, but does not fully specify the control flow. Objective: The goal is to develop a planning algorithm that supports the case worker in planning case-based business processes at run-time. Method: We identify the requirements of run-time planning of partly structured processes by analyzing the admission process for the master degree at FHNW. To plan the process instance, we develop a planning algorithm. Our planning algorithm is evaluated using concrete cases provided by FHNW in order to demonstrate real application. Results: The planning algorithm reflects the requirements for serializing tasks at run-time. Conclusion: Our planning algorithm allows to automatically deriving context-specific execution plans for CMMN models at run-time.

Context: Organizations act in a highly competitive markets, which forces them to be able to quickly adapt and optimize their processes. Case Management Model and Notation (CMMN) supports modelling run-time adaptation of partially structured business process models, but does neither allow selection nor sequence of tasks. Objective: Our goal is to develop an approach that computes sequences of tasks such that a context-specific goal is satisfied. We apply the SMA* algorithm to support run-time planning of partly structured parts of a business process in order to find an appropriate sequence of tasks. Method: We perform a literature review in order to derive the most suitable heuristic search algorithm. To support the selection and specification of tasks, we extend the CMMN metamodel. A running example is presented to show practical applicability of the approach. Results: The extension of the CMMN metamodel reflects the requirements for serializing tasks at run-time. Furthermore, we modified the SMA* algorithm and defined a heuristic function. Conclusion: Our approach allows to automatically derive execution plans for partly structured business processes depending on the context.
