Applying Tropos4AS to water security domain: Recycled water system case study

In this study, we elicit and specify a goal model for the recycled water system of Abu Dhabi Emirate, along with the constraints and strategies defined within the system boundary. The preliminary results are evaluated using Systems Dynamics approach by modeling and simulating the goals and requirements defined using Tropos for Adaptive Systems (Tropos4AS) method. System Dynamics methodology allows investigation of the interactions between goals and the evaluation of the results. This paper demonstrates preliminary evaluation of the System Dynamics ability in validating requirements engineering models. Moreover, the linking of System Dynamics and Troposa4As is found promising since it seems it can improve the collaboration between goals of different stakeholders for better planning, by considering the prioritized goals resulting from the hybrid analysis.
