Operator interface and situation perception in hierarchical intelligent control: a case study

This paper covers some operator interface issues of a hierarchical intelligent control system. The logical structure of the operator interface function in reference to the NIST real-time control system (RCS) architecture has been investigated. An emphasis is that the operator interface should be integrated seamlessly with existing systems. A design issue is to allow operators to be involved in system operations in different degrees, Operators at different control levels have different perceptions of the world. Software service personnel and control operators may require totally different types of information
