According to Coughlan (1995) a special purpose simulator is distinguished from a simulation language or system by the three properties above.  Most simulation systems are only used by trained experts.  The special purpose simulator is developed to insulate a user from the complexities of the underlying system.
	The main part of a special purpose simulator is the parameterized model of the system being studied.  The front end interface guides the user in the set-up of the parameters in a similar manner to many familiar software wizards.
	Once the model is run, the results are presented in report format.
	These models have been created for many industries and for many purposes.  They are targeted at users with almost no simulation experience.  These include manufacturing engineers and managers.
	One MS Windows based simulation package is SIMAN, a commercial spreadsheet, which uses BASIC as the underlying programming language.
