The SIMRAND I computer program: Simulation of research and development projects
SIMulation of Research ANd Development Projects (SIMRAND) is a methodology for the selection of the optimal subset of system or tasks to be implemented on a research and development (R and D) project. The SIMRAND methodology models the alternative subsets of systems or tasks under consideration with alternative networks. Each path through an alternative network represents one way of satisfying the project goals. Equations are developed that relate the system or task variables to the measure of preference. Uncertainty is incorporated by treating the variables of the equations probabilistically as random variables, with associated cumulative distribution functions. Cardinal utility functions are assessed over the measure of preference. The SIMRAND I Computer Program is run for each alternative network, incorporating the network structure, the equations, the cumulative distribution functions, and the utility functions in a Monte Carlo simulation model. The alternative network yielding the most-preferred value for the measure of preference, or the highest utility function value, is the optimal network. This Report documents the SIMRAND I Computer Program (Version 5.0 x 03) written in Microsoft FORTRAN for the IBM PC microcomputer and its compatibles. The SIMRAND I Computer Program comprises eleven modules - a main routine and ten subroutines. Two additional files are used at compile time, one inserts the system or task equations into the source code, while the other inserts the dimension statements and common blocks. The SIMRAND I Computer Program can be run on most microcomputers or mainframe computers with only minor modifications to the computer code.
