Integrated Model of Fatigue and C-17 Approach and Landing Operations

Fatigue is a common occurrence in several occupational fields, often resulting in operator performance and health issues. Biomathematical models of fatigue have become useful tools in several fatigue risk management programs. However, these tools still have limitations in terms of identifying specific performance outcomes affected by fatigue, as well as individualizing fatigue estimates to individual operators. The integration of computational cognitive models and biomathematical models can help solve these issues in a complex operational context. The current effort aims to develop an integrated model of fatigue in the context of C-17 approach and landing operations. Specifically, we integrate a biomathematical fatigue model with a task network model to estimate performance degradation due to fatigue. The following paper outlines the development of the task network model and integration with the biomathematical fatigue model.
