Interoperable Approach to HMI and Supervisory Systems in Man-Machine Systems

Automation and higher level of control systems development cause that function of human in Man-Machine System (M-MS) is frequently moves to the function of supervisor. Observed evolution of M-MS systems accompanies development of Information and Communication Technologies (ICT) especially supervisory systems which are important aspects of interoperability in manufacturing systems. The higher and higher demands are put before those systems and more and more compound tasks are expected to realize especially connected with control, diagnostic, monitoring and managing. The main questions of supervisory systems evolution are inference mechanisms and so called intelligent systems (fuzzy logic, experts systems, artificial neural networks) which can be implemented to aid decision-making process, making faster and adequate diagnosis of occurrences and failures, formulating conclusions about symptoms-failures relationships and preventive or removing actions. In the paper example of HMI/SCADA system was presented which enables to implement and use in decision-making process interoperable heuristic knowledge of the user. Moreover the application which allows to realize fuzzy control system using user interface applied in HMI/SCADA system was shown. Presented examples were dedicated for material handling devices and has been tested on an overhead traveling crane example.
