Mapping the network of industrial processes from a Life Cycle Inventory database

Résumé

In spite of rising climatic and environmental concern, modeling of Input-Output theory, Industrial Ecology, Life Cycle Assessment, and Material Flow Analysis are conspicuously under-represented in complex networks research. To fill that gap we compare various network representations of interactions occurring in the aforementioned domains, following [1], and extending the scope (e.g. to chemical reactions networks, and the Von-Neuman’s growth problem). First the different methods to construct such networks are summarized, starting from available data. Then, a classical empirical study of network’s properties is conducted and shows a high heterogeneity. More precisely, networks stemming from Life Cycle Inventory databases are compared to networks built using mappings with actual industrial process operated by economic actors, such as hybrid Life Cycle Analysis, based on Input-Output Analysis at international, national, and even regional scales. The benefits of various pre-processing steps such as monopartite projection are assessed and higher-order formalism (e.g, hypergraphs) used for example in omics research are discussed. Existing applications, for example community finding [2] are exposed, and limitations of conducting a network-oriented analysis are debated (such as data availability, uncertainty in databases, or lack of spatial information). Special emphasis is drawn on criticisms raised over the interest of the network formalism with respect to scale-dependence. The way this topic is dealt with by linear algebraic tools [3] that are standard in those fields is analyzed in that light. The interest of mitigating this issue using recent multi-scale representations [4] and aggregation techniques in complex networks research is assessed.
