Simulation of small systems using microcomputers

This paper focuses on models of small or partial systems, which generally tend to be less complex than the usual type of models. Microcomputers provide an ideal vehicle for these exercises, and the capabilities, advantages and limitations of these are discussed. Philisophical advantages of this approach are given. These are illustrated by descriptions of a number of modelling exercises conducted recently by the author, including seed production in Rhodes grass pastures, plant dynamics in Mitchell grass pastures, and post-harvest management of horticultural produce.
