Ergonomics in industrial automation

Tyrva V.O.  Automation of man-machine ergative system based on anthropomorphic control application

The paper discusses the results of theoretical and experimental research of object control in man-machine ergative system. Such control type is named anthropomorphic control by the author for being a part of combined object control by human operator and a control automaton. A procedure for modeling controlled processes in the system's state space is offered on the basis of a set of incomplete representations of simple motions underlain by the model of human operator's and machine's actions and responses used in engineering psychology. Based on the classical maximum speed problem's solution, the anthropomorphic control of a boat in hazardous conditions is designed. The automation of a man-machine system is examined where combined control devices based on new operation principles are applied in the HMI.

Keywords: man-machine system, control, model, motion representation, ergative system.

Rozhkov V.I., Lakhai A.A.  Information models design for automated control systems of megalopolis gas distribution network taking into account ergonomic requirements

The developers of information models using SCADA technologies often ignore ergonomic requirements. The practice of developing the structure and algorithms of operator activities often lacks at the design phase. However, optimal allocation of functions between operator and machine as well as among operators should be organized at this phase, otherwise it may take longer time for operators to make decisions in emergency situations. Information model-based analysis of the activities of gas distribution network supervisors enables the development of their activity algorithms; further application of the mathematical tool of A.I. Gubinsky generalized structural method results in man-machine system's quality estimates. In general, the application of this approach significantly improves the operation quality of the man-machine system and reduces the emergency crew mobilization time.

Keywords: information models, ergonomics, gas distribution network, operator's activity algorithm, generalized structural method, man-machine system's quality estimates.
