GPSS/PC is an implementation of GPSS, the General Purpose Simulation System. It was created primarily as an interactive simulation environment for personal computers and dedicated workstations. GPSS/PC is distinguished by its visibility and interactivity. With the introduction of Version 2, it has added interactive graphics and animation to its simulation(More)
Concomitant anal fistulotomy (F) and incision and drainage (I&D) of ischiorectal abscesses (IA) are often avoided, for fear of irreversibly impairing anal continence. However, failure to identify and treat the frequently associated trans-sphincteric anal fistula dooms the patient to recurrent anal suppurative disease. We have employed an aggressive approach(More)
GPSS Worldti is a complete redesign and reimplementation of the popular GPS S/PCti Simulation Environment. The limitations of the old PC DOS environment and the emerging trends in desktop computing have combined to motivate dmstic changes which am planned for the new environment to be made available beginning in 1992. 1 DESIGN OBJECTIVES The quickly(More)
GPSS/PC is a popular implementation of the discrete event simulation language GPSS, the General Purpose Simulation System. GPSS/PC has interactive graphics and animation tightly integrated into its simulation environment. Its graphics windows allow viewing and manipulation of the simulation via an optional pointing device, and assertion of all simulation(More)
GPSS/PC is a new implementation of GPSS, the General Purpose Simulation System, with several interactive extensions to the user interface. Its overall design integrates a syntax directed statement parser with the run time system. This results in a number of advantages in the controllability of running simulations. Unlike traditional simulation language(More)
Simulation Studiom is the optional component of the GPSS World'' " Simtttation Environment responsible for user-created graphics and the animation of simulations. It can operate in any of three modes: closely linked online with a simulation, as a Post-Processor, or as a stand-alone draw and animation program. It is currently scheduled for release in the(More)
A typical performance evaluation consists of the identification of resources, the definition of system boundaries, the measurement of external and internal performance variables, and finally the interpretation of data and projection of system performance to hypothetical environments. These projections may be used to estimate the cost savings to be expected(More)
