GASP IV

摘要

GASP IV is an extension of the next event simulation language GASP II. A generalization definition of "event" and additions to language structure enable GASP IV to be used continuous or combined models while retaining full power of GASP II for discrete models.

Continuous system state description may be in the form of a set of algebraic and/or differential equations. GASP IV handles the details of state and event control (including state variable integration when necessary), information storage and retrieval, system performance data collection and analysis, and report and plot generation.

In addition to the models which can be coded in GASP II, the following types of models have been successfully coded in GASP IV: Systems Dynamics Models (Industrial, Urban, and World Dynamics Models); Mechanical Impact Models; and Chemical Process Models.
