Understanding Fatigue Patterns for Dynamic Tasks: A Recurrence Model Approach
SessionOE11: Fatigue
DescriptionThis study used a recurrence model to evaluate fatigue in shoulder-level order picking and examined the application of a recurrence model to incorporate factors associated with energy decaying and boosting. In this model, the initial work cycle was described using an exponential function with a fully rested initial energy. β was defined as the decay rate, and α was defined as energy gain from resting. t_2 was the expected time to full fatigue, with resting periods in between.
14 adults (7 male) were invited for a 3-hour-order-picking experimental study. The results demonstrated a strong model fit (R^2 mean = 0.89). Fatigue accumulation was significantly influenced by period, pace, and personal factors such as sex and BMI. Changes in task conditions affected time to fatigue and energy recovery, underlining the model's predictive ability to gauge fatigue development. The findings highlight the importance of individual differences and task dynamics in fatigue management.
