Modelling has been traditionally regarded as a manual task. As such it has many drawbacks. Automated modelling is a research field developed to improve the model building process and to reduce human involvement. In this paper an automated modelling systems approach is given. Modelling of a system is based on system decomposition. Bond graphs and block diagrams were chosen as the model representation language. The basic item of a model is a component represented as an entity that contains all the information on its structure, properties and behaviour. Editing of the model is done in a user friendly visual environment. The models are held in a database which supports common model management operations. The study of the system behaviour can be conducted by simulation. The approach has been applied to the modelling and simulation of internal combustion engines.
