System behaviour prediction by modelling and simulation

Modern product design requires a structured systems engineering approach, such as that characterised by the V-model. Different phases represent different levels of abstraction and detail, and modelling is essential for moving from one phase to the next.


Iterations between phases are also necessary in order to arrive at a feasible and cost-effective design. What is an effective way to apply modelling during product design? To what extent will different models be applied during the various phases of product development? This Mikroniek article presents a rationale for model-based systems engineering. The first part elaborates on the use of modelling during the various development phases. In order to illustrate this, the content and scope for each phase are explained. It is emphasised that the extent of the requirements engineering phase is often underestimated because it comprises not only the specifications, but also the clarification of the design scope and interfaces. In the second part, the practical application of using such a model is illustrated by the implementation of the design for a linear motion system.
