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 system´s 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.
