Two different situations may appear: the most favourable one in terms of time consuming is when the factorized matrix from the original analysis is kept on disk and reused for the sensitivity analysis. In this case, the time required for the sensitivity analysis is short compared to the one required for the original analysis. The most unfavourable situati
