C-Flavours: A Scheme-Based Flavour System with Coroutines and its Application to the Design of Object-Oriented Simulation Software

Abstract This paper explores the benefits of prototyping object-oriented simulation models in a symbolic programming language. After a brief description of the project's motivation the main characteristics of object orientation as a programming methodology are discussed within the context of the Scheme programming language. This is followed by a description of the Canterbury Flavour System (C-Flavours), with particular emphasis on how coroutine methods are used to support process-oriented modelling styles. A characterization of architecture and usage of a typical queueing networks simulator then serves to demonstrate C-Flavours' utility for this class of applications. The paper concludes with a brief summary of related research activities in this area and some general comments on the merits of object orientation for the construction of modelling systems and simulators.
