Documentation for the SAINT Simulation Program

The overall structure and individual FORTRAN subprograms of the SAINT simulation program are described. SAINT (Systems Analysis of Integrated Networks of Tasks) is a network modeling and simulation technique developed to assist in the design and analysis of complex man-machine systems. SAINT consists of a symbol set for modeling systems and a computer program for analyzing such models. SAINT provides the conceptual framework for representing systems that consist of discrete task elements, continuous state variables, and interactions between them. While SAINT was designed for modeling manned systems in which human performance is a major concern, it is potentially applicable to a broad class of systems--those in which discrete and continuous elements are to be portrayed and quantified and whose behavior exhibits time-varying properties. SAINT provides a mechanism for describing these dynamics so a systematic assessment can be made of the relative contribution system components make to overall system performance.
