Formal early design synthesis of mobile work machine

This article introduces a formal early design synthesis and its corollary, function behaviour structure, to an early design analysis and identification of concept for complex systems. First, the article presents the state of the art of design modelling frameworks, tools for dynamic system synthesis and behaviour simulation. Secondly, the key elements for function-based design synthesis and behaviour modelling are discussed, as well as the interest and actual limitations of the general architecture model applied to early design of complex systems. Finally, the article proposes an alternative approach in order to allow systematic design and to explore behaviours of functions and structures early in the development stage with the intention of future coding as a computational tool to allow design automation
