A Method for System Modelling and Partitioning in the Definition of Automotive Multiplex System Architectures

In the definition of automotive multiplex system architectures, several problems arise due to a lack of preciseness in the specification of customer defined functional requirements and devices characteristics.

To cope with this problems, we propose to define a systematic flow of the design process and a structured organization of the information, that gives the system designers guidelines on how to make implementative and technological decisions about the architecture of a multiplex system.

The purpose of this paper is to present a structured graph-based design procedure, that helps the system designers in the partitioning and modelling of the system, allowing them to define architectures more easily and helping them to estimate performance and costs of the system.
