Abstract

Due to unprecedented change of global climate, the structure of the global water resource has been changed in an unpredictable way. How to cope with the change of the water structure has become a crucial agenda for the water resource management area. The smart water grid (SWG), considered as an infrastructure for the future water resource management, is recently being actively researched and developed in the world wide. Looking over the state-of-the-art, they are not clearly established, viewed from their own perspectives; e.g., IT-based SWG, Pipeline Technology-based SWG, Filtering Technology-based, without showing: 1) The whole system view, 2) System lifecycle, and 3) User and stakeholder perspectives.

In view of the above, we approach the problem of SWG from a systematic perspective, by clearly defining development items in the conceptual stage based on the systems engineering international standard. Specifically, in this thesis, we develop system architecture for SWG based on Zachman framework, a powerful method that can give a compact and clear architecture in the conceptual stage. It contains all the viewpoints required for the system development from the goal-oriented to technological as well as implementation, analysis, and utilization of the SWG.

Based on the architecture developed in this thesis, an architecture for Korean Smart Water Grid System has been proposed, followed by verification through interviews and questionnaire. The smart water grid system architecture development framework presented in this study can give a reference model for the smart water grid system, which can be applied to the various environments where water resource and amount can be varied significantly.
