This paper introduces a graphical, computer aided modelling methodology that is particularly suited for the concurrent design of multidisciplinary systems, viz. of engineering systems with mechanical, electrical, hydraulic or pneumatic components, including interactions of physical effects from various energy domains. Following the introduction, bond graph modelling of multibody systems, as an example of an advanced topic, is briefly addressed in order to demonstrate the potential of this powerful approach to modelling multidisciplinary systems. It is shown how models of multibody systems including flexible bodies can be built in a systematic manner. (C) 2007 Elsevier B.V. All rights reserved.

We propose a new approach dealing with the combination of bond-graph with GDEVS formalism for modeling and simulation of complex systems using discrete event techniques. We show how to build discrete event simulation models for bond graph elements, with either piecewise linear input-output trajectories or any kind of polynomial trajectories. One of the main advantages of our method is the reduction in the number of simulation Steps, and therefore the possibility of studying dynamic hybrid systems using only the discrete event paradigin.

This paper outlines the need for computer based modeling tools in the simulation field. The modeling tasks that should be automated by a modeling environment to describe the dynamics of a system assembled by a set of sub-systems will be presented. The benefits of reusing a model by analyzing its external physical causality rather than its computational causality will be evidenced by means of an application example.
