Abstract

The PREP utility assists in the preparation of a Monte Carlo analysis of the behaviour of a model encoded into a computer program. The ultimate goal of this type of analysis is to determine the model response to variation in its input parameters, to assess the uncertainties in the model prediction and to correlate these uncertainties with the most influential model parameters. The part of the analysis dealt with by PREP is the preparation of the input stochastic sample for the analysis, given the distribution of the input parameters. PREP tries to ease the transformation of the user model from deterministic (one execution corresponding to one set of values for the input parameters) to stochastic (many executions to cover assigned value distributions for the input parameters). PREP is described with reference to two alternative applications: within the LISA package (for the analysis of the risk from nuclear waste disposal) and with a user supplied model.
