Automatic code generation for simulating information systems

In the analysis and design of information systems, computer-based simulatio n models are often used ns cost-effective alternatives to mathematical syst em analysis approaches due to the high complexity of the systems. However, the process of development a correct simulation program is a difficult and time-consuming task, even ii specialized simulation languages. In order to reduce development time, to reduce requirements for knowledge of simulation methodology and programming language, and also to increase program standar dization, an automatic code generation system was developed and implemented . This code generation process is based on a Petri net model of the informa tion system, fr om which simulation programs in the target language GPSS ar e automatically produced. Automation of the code generation process require d the adoption of certain conventions for Petri net models and the adoption of a tabular internal computer representation. We describe the design deci sions that were made in order to implement a working system. Extensions to the development of automatic code generation systems into other target lang uages are also discussed.
