AUTASIM: A system for computerred Assembly of Simulation Models

The AUTASIM System (Automated Assembly of Simulation Models) is described. The system is designed to rapidly assemble discrete event, stochastic simulation models of node network systems. Systems of this type are distribution systems, plant operations, systems for the provision of services, transportation systems, and combinations of these. Models can be used for comparative analysis of new concepts and proposed systems with other systems. The main AUTASIM components are a Module Library of computer programs, a program called the Model Assembler and a Model Description Language. The Library contains functional and simulation service modules which are the “building blocks” for the simulation models created. The Model Assembler program reads a coded model description, selects the required modules from the Library, and creates the necessary linkage routines for a complete model program. The Model Description Language, AUTASCRIPT, is defined. The operation of the FORTRAN coded Model Assembler and linkage control programs is described, as is the GASP based model simulation control.
