Cyber-physical systems are a new research discipline that involves many areas. The key concept behind this discipline has to do with a strong interaction between the physical world and a computing system, which should be transparent to an external observer. Thus, it cannot be determined whether the systemâs behavior is due to the influence of the environment or the actions of the computing system. In this paper, a requirement analysis approach for these systems is presented. It is called 3D Approach and it is based on the well-known 4-Variable Model. The 3D Approach came out as the result of systematizing practical experiences taken from the design of a biodigester.
