The paper presents a SHEL oriented requirements engineering approach, which has been applied in a case study dealing with the definition of the requirements for a new railway traffic control system. The SHEL model (E. Edwards, 1972) provides an integrated view by considering any productive process or activity performed by a combination of software, hardware and liveware (SHEL) resources within a specific environment. A set of SHEL oriented requirements describes the different views in a complex system. The requirements are grouped into three main classes, namely, functional, cognitive and quality requirements. The paper points out the issue of integrating different types of requirements.
