Assessment of the key factors for ergonomic design of management information systems in coal mines

Abstract

Using an analytic-synthetic model of ergonomic research of management information systems (MIS) in coal mines, we identified 13 elements which were used to define eight factors that impact operator’s performance. These eight factors were further reduced to five key factors after the application of expert assessment. We have defined 23 indicators for these key factors, ranked by means of the analytic hierarchy process method. This paper includes a detailed ergonomic analysis of the five key operator quality indicators, namely, shape and size of the control panel, functionality of the video display terminal, keyboard functionality, alarm response time and expansion of the MIS with environmental parameters. Based on the condition prior to and after the proposed changes, we were able to use this approach to determine and discuss the operator quality index.
