The conceptual modelling process involves deciding what is relevant and should be included in the model to meet the aims of the current investigation. This means a key aspect of a simulation study is that the modeller understands the context of the problem so that they are able to identify what elements of the real system will be relevant to the conceptual model and also the relationship between these elements. Conceptual modelling is sometimes referred to as the art of simulation as contrasted with the scientific aspects involving model coding and statistical analysis. Robinson (2020) indicates the relatively limited amount of attention that has been paid to this creative side of modelling compared to the scientific aspects. One exception is the classic text by Robert E. Shannon (1975).
