Performance Study of Light Assembly Operations Considering Time Pressure and Task Complexity

Abstract

Performing tasks of different complexity under different time pressures has different effects on the operator's operational performance. In this paper, the Lego model is used to simulate the actual light assembly production operation, and the light assembly experiment with different complexity and different time pressure is designed. The operator's operational performance indicators are recorded to analyze the impact of task complexity and time pressure on the operational performance of light assembly operators. The results show that the task complexity leads to significant differences in the operator's operational performance. Time pressure does not lead to significant differences in the operator's operational performance. There is an interaction between the two; there are significant differences between the four types of assembly task completion error rates.
