Three issues are relevant to model interpretation. As with parametric analysis, the idea is modify parts of the structure of the model and analyze the effects. The second aspect is to explain the results obtained from model solution using the mathematical structure of the model. Parametric analysis has long been supported in model management systems.
Spreadsheets routinely support what if analysis and goal seeking.
An important feature of their approach is the analysis of the impact on the results of a model when changes are made to the parameters of a surrogate model. Piela et al. Such a rationale documents the model and can be used to aid model comprehension in combination with a browser.
