The Model of Changes in the Psychomotor Performance of the Production Workers

Abstract

Abstract:The results of the study indicated a relationship between the worker's psychomotor performance at a certain time of the work shift and the changes in the level of their fatigue. The performance is reflected in the production results, such as the decrease in the productivity and an increase in the number of defects. The results of the study made it possible to define a model (algorithm) of changes in the worker's psychomotor performance. The developed model identifies the direction of the organisational changes in a production plant environment operating in the rotational shift pattern. The organisational changes can relieve staff in the night and minimise the risk of the declining production efficiency during work at night.

Use of the Methodology of Network Thinking for a Fatigue Criteria Investigation Based on the Example of Mining Companies

“…One such area is certainly bituminous coal mining, which both in Poland and around the world is subject to special supervision because of the threat to life involved in underground workings [7,8,9,10]. This situation arises due to the specific working conditions in this sector and is associated with the occurrence of virtually all natural hazards, the avoidance of which requires employees to have a significant level of psychomotor performance [11,12], which can be achieved by managing fatigue. The need for aggregation of many variable factors, conditions restricting the use of the full spectrum of available tools by employees fatigued due to the harsh working environment (underground coal workings), as well as the need to perform strenuous manual labour, brought about the need to apply a model quite different from the aforementioned ones.…”
