A huge thank you to my co-authors Judith Verstegen @utrechtuniversity.bsky.social, George van Voorn @w-u-r.bsky.social, Sabin Roman from the Jozef Stefan Institute and Arend Ligtenberg @w-u-r.bsky.social for their work during this process.

On a side note, I started work on this topic during my PhD after getting funding from my graduate school @pe-rc.bsky.social at @w-u-r.bsky.social in late 2020. We first submitted the manuscript in July 2022. In other words, we spent more time in the publication process than on the actual research!

We hope this work paves the way towards a principled, measurable, and replicable science of scenario generation.

Evaluated using three distinct criteria for scenario sets (diversity, plausibility, and comprehensiveness), we find that our proposed approach performs equally to or better than the three existing approaches.

We compare our proposed method "scenario search" against three other scenario generation methods (clustering model outputs, generic archetypes, and scenario matrices) using Schelling's segregation model as a case study.

Scenario search: finding diverse, plausible and comprehensive scenario sets for complex systems | Socio-Environmental Systems Modelling

New paper! In sesmo.org/article/view..., we propose a new optimization-based approach for generating scenario sets from simulation models. These scenario sets are small collections of model runs representing the full diversity of the underlying model's full behavior space.

"This e-book introduces System Dynamics Modelling to novice modellers. It is specifically designed to support courses on simulation methods at the Faculty of Technology, Policy and Management (TPM) at Delft University of Technology (TU Delft) in the Netherlands, including Systems Modelling 3 and Introduction to TPM Modelling. However, it can also be used by other institutions that follow a practice- oriented and skill-oriented approach to learning, while it also offers sufficient theoretical information to support autonomous learning. We choose to publish the e-book under an open access license so that SD learners from all over the world can study the material, independent of their study programmes or university access."

This is a useful guide to System Dynamics modelling - Open Access

Data visualization is challenging, especially when moving from exploratory purposes (i.e., to discover or understand the data) to explanatory purposes (i.e., communication with others).
In a paper led by @hadjimichael.bsky.social we discuss different visuals iopscience.iop.org/article/10.1...
