English Abstract Sensitivity and uncertainty analysis are generally
recognized as important and indispensable parts of the modelling process.
The easy availability of tools for performing these analyses contributes
substantially to a reliable and efficient development, assessment and
application of mathematical models. For this reason a comprehensive and
flexible software package UNCSAM has been developed at the RIVM for
performing sensitivity and uncertainty analysis on a large variety of
models. UNCSAM combines a Monte Carlo based approach (sampling and
simulation) with regression- and correlation analysis, to obtain a clear
picture of the sensitivities and uncertainties and their main contributors.
The package is developed in ANSI standard Fortran 77, embedded in an ANSI-C
shell for dynamic memory allocation, and can be installed on a variety of
devices. The manual describes the scope, installation and use of UNSCAM,
release version 1.1.
