We can understand computer simulation language as the language which describes operation of a simulation on a computer. It can be broadly categorized in following two categories: 1. continuous 2. Discrete event Many lnguages have a graphical interface and are capable of performing simple statistical analysis of the results. While using discrete-event languages we can easily generate pseudo-random numbers and determine variables using different probability distributions. Some of the Discrete event and continuous language packages have been listed below: AutoMod eM-Plant Arena ExtendSim simulation environment for discrete event, continuous, discrete-rate and agent-based simulation.[1] GASP GPSS Plant Simulation Simio software for discrete event, continuous, and agent-based simulation.[2] SimPLE++ SimPy, an open-source package based on Python SIMSCRIPT II.5, a well established commercial compiler Simula Java Modelling Tools, an open-source package with grap...

Discuss the following periods in simulation history? a. The period of Search: Simulation was conducted in FORTRAN and other gernal purpose languages. No specific simulation specific routines. Much effort was on expanding searcn for unifying concepts and the development of reusable routines to facilitate simulation(1955-60) b Advent : It is the period of forerunners of SPL we use today(1961-65) GPSS developd by Geoffery Gordon at IBM and appeared in 1961. General Purpose Simulation system was developed for quick simulation of communication and computer system. It is a block disgram based representation (similar to process flow diagram) and suited for queuing models. Phillip J Kiviat developed GASP (General Activity based simulation program). Originally it was based on GPL ALGOL but later based on FORTRAN. other SPL developed are SIhMULA(extension of ALGOL) c. The Formative period (from 1966-1970) Concepts were reviewed adn refined to promote more consistent re...
