Abstract: | Abstract In this paper, an approach dealing with the dynamical aspect of information systems modelling is described. The main idea that governs this article is that the bond-graphs language can be applied to information systems theory. An extension of bond-graphs words is presented to cope with information exchanges. The aim of this task is to show that bond-graphs concepts can be used to model all the aspects of the information system model (static, dynamical,.). After a brief introduction, the bond-graph language for information systems is dealt with. Particular cases and a short comparison with the Jackson software development method constitute the subject of the sections that follow, then the tools required to model the running of the information system modelled by Bond-graphs are presented. The problem is clearly presented as follows: can the energetic point of view be applied to information systems? If so, is it possible to apply the bond-graph language to those systems? |
