A Pascal simulation model for the analysis of queueing systems

Abstract This paper puts forward a PASCAL simulation model for the analysis of queueing systems. The model is applied to a computer facility queueing problem with and without preemption. The PASCAL program was executed on a PS2 using DOS 3.30, and TURBO PASCAL 4.0. TURBO PASCAL is popular dialect of PASCAL on personal computers. It provides several extensions to standard PASCAL that makes it easier to use. The TURBO PASCAL system includes an editor for creating and modifying programs and a compiler and loader. It also supports random access to files and has the capacity to save and retrieve files on a disk. TURBO PASCAL supports the data type string along with a number of built-in procedures and functions for manipulating strings. The simulation program is easy to understand and implement.
