MOSAIQUE – A network based software for probabilistic uncertainty analysis of computerized simulation models

Uncertainty and/or sensitivity analyzes are widely used in safety analysis using a computational code. When performing uncertainty analysis, massive time and resources are needed to satisfy the requirements of sampling of the statistical parameters or even distributions of the key parameters. MOSAIQUE (Module for SAmpling Input and QUantifying Estimator) was developed to facilitate the uncertainty analysis using a simulation code. The major functions of MOSAIQUE are (1) to sampling parameter based on its distribution information and generating sampling inputs, (2) to control the calculations using multiple PCs, and (3) to process the calculation results for the generation of information for key parameters. MOSAIQUE was applied for the simple uncertainty calculation, in which tedious time consuming processes could be sufficiently automated including large time reduction by using network computing.
