In order to identify potential differences in the themes associated with the validation of agent-based and systems dynamics models, the analysis was run again for the two different subsets of papers (ensuring that the autocoding function provided in NVivo was also operating based on the reduced sets of papers). Similarly, this analysis was repeated to classify challenges more specifically associated with modelling disruptions, resulting in the identification and mapping of the 50 unique validation themes shown in Fig. \ref{222026}.
Real-life perspectives on simulation validation and the modelling of disruptions
Having identified and mapped key themes relating to model validation and the simulation of disruptive events from analysis of agent-based and system dynamics literature, a survey was now structured (using the Typeformâ„¢ online survey tool) to assess how academic, industrial, and public audiences perceive the relevance of each of these themes. To give some measure of opinions a Likert scale question was devised and assigned to each of the 50 themes suggested in Fig. \ref{222026}. A transcript of the resulting survey that was distributed is provided in Appendix XX.
