Community Modelling in Dynamic Material Flow Analysis: Transparency, Reproducibility and Comparability
Scenario models for material futures, and dynamic stock and flow models with high resolution, in particular, are data intensive and computationally challenging. The Open Dynamic Materials Systems Model (ODYM) was developed to facilitate data handing and to increase the transparency, reproducibility, and comparability of such models. It is programmed in Python. The first models programmed with ODYM and related databases are now published. However, there is a significant entry barrier into modelling with ODYM because of a lack of a GUI or still a low number of case studies. In this session, we will first present ODYM and other current approaches for open dynamic stock and flow models and data handling. We will then transition to an open panel discussion to discuss options for community-driven data gathering and modelling of material futures, as well as collaboration options.
