  As manufacturers and technologies become more complicated, manufacturing
errors such as machine failure and human error have also been considered more
over the past. Since machines and humans are not error-proof, managing the
machines and human errors is a significant challenge in manufacturing systems.
There are numerous methods for investigating human errors, fatigue, and
reliability that categorized under Human Reliability Analysis (HRA) methods.
HRA methods use some qualitative factors named Performance Shaping Factors
(PSFs) to estimate Human Error Probability (HEP). Since the PSFs can be
considered as the acceleration factors in Accelerated Life Test (ALT). We
developed a method for Accelerated Human Fatigue Test (AHFT) to calculate human
fatigue, according to fatigue rate and other effective factors. The proposed
method reduces the time and cost of human fatigue calculation. AHFT first
extracts the important factors affecting human fatigue using Principal
Component Analysis (PCA) and then uses the accelerated test to calculate the
effect of PSFs on human fatigue. The proposed method has been applied to a real
case, and the provided results show that human fatigue can be calculated more
effectively using the proposed method.
