•Outdoor lighting design using graph structures.•Rule-based lighting control.•Rules expressed with graph transformations.•High scalability.•Integrated design and control process.
Design and control of outdoor lighting systems is a complex task, which is made even more difficult by introducing features like dynamic, sensor-based operation, multiple lighting levels and sophisticated, adjustable luminaires. This paper proposes an integrated approach, based on formal graph-based models and methods, to handle both of these tasks. The introduced formalisms help handle the state-space explosion related to the aforementioned characteristics. Control is performed by means of AI techniques (including rule-based systems and pattern matching), which is applied to the system using graph transformations. An illustrative, simple example is carried out throughout the paper, but the presented methods are highly scalable, which made them applicable to several practical projects of varying scale and characteristics.
