Network representation and analysis of a large-scale wastewater treatment plant

摘要

We mapped a large-scale wastewater treatment plant onto a complex network and we investigated how the structural properties of the graph evolve in time as the facility is operated. The Viikinm?ki plant is mapped onto a dependence network in which the nodes are online process measurements and interconnectivity between nodes encodes pairwise correlations between the corresponding time series, as estimated over moving-windows. In this initial study, the construction of a graph of Viikinm?ki is presented and results are discussed with the goal of understanding its usability as model for process interactions and encoder of latent structures.
