Abstract

SIMNET is a network-based general-purpose discrete simulation language developed in totally compatible versions for the micro, mini, and mainframe computers. The language utilizes a fresh design approach that limits the number of nodes to exactly four: a source, a queue, a facility, and an auxiliary. Traffic among the four nodes is controlled by using special assignments, a strategy that is particularly suited for use with the IF-THEN-ELSE-ENDIF constructs. PROCs are used in a “stand alone” fashion to simulate an entire system with repetitive elements. A unique feature of SIMNET is the use of interactive (characters) graphics to estimate the transient period, following which the steady state run length is specified by the user and independent or global statistics are collected, all within the interactive mode of execution. The paper compares SIMNET with GPSS, SIMAN, and SLAM.
