A general guideline for choosing an uncertainty method is given in this wiki. Many applications will involve only a forward uncertainty analysis, reflecting the identified uncertainties in model structures, drivers and prior estimates of parameter values expressed either in terms of prior probabilities or fuzzy measures. No real philosophical issues arise in forward uncertainty analysis. The main Code of Practice requirement here will be to demonstrate an adequate approximation to integrating over the sources of uncertainty (e.g. by testing convergence of output quantiles to different numbers of samples under similar prior assumptions).
