ORMONTE: An uncertainty analysis code for use with user-developed systems models on mainframe or personal computers: A user's guide
Documentation is provided for a general purpose uncertainty analysis code entitled ORMONTE. The code is intended to be linked with FORTRAN-77 models designed by the user. ORMONTE is capable of performing sequential single-variable sensitivity studies (SVSS), elasticity analyses, and multivariable sensitivity studies (MVSS) by acting as a driver on the user's model. The MVSS function utilizes the Monte Carlo simulation method of probabilistic analysis. The model accessed by the ORMONTE driver code and the names and characteristics of the modeler's uncertain variables are provided by the user. ORMONTE is essentially a bookkeeping code which keeps track of inputs and outputs defined by the user, samples the user-defined uncertainty distributions, repeatedly runs the user's model, and produces statistical data and output probability histograms for the output variables of interest to the user. ORMONTE has been utilized extensively by the USDOE and its Oak Ridge contractors, Martin Marietta Energy Systems Inc., and its predecessor, Union Carbide Corp.; Nuclear Division, for the economic evaluation of large-scale energy projects for which computer models have been constructed for performance and cost projection purposes. ORMONTE has been used on several computer systems including a Cray, several VAXes, two IBM-360 mainframes, and DOS compatible PCs (along with the appropriate FORTRAN-77 software). The detail documentation provided here deals mainly with the PC version to be utilized with RM/FORTRAN; however, installation on a mainframe is reasonably simple. An example problem and complete ORMONTE input and output therefrom are provided. 3 refs., 24 figs., 6 tabs.
