An Approach for Integrated Analysis of Human Factors in Remote Handling Maintenance

Abstract EN

Considering dangerous environmental conditions, maintenance of radioactive equipment can be performed by remote handling maintenance (RHM) system.

The RHM system is a sophisticated man-machine system.

Therefore, human factors analysis is an inevitable aspect considered in guaranteeing successful and safe task performance.

This study proposes an approach for integrated analysis of human factors in RHM so as to make the evaluating process more practical.

In the approach, indicators of accessibility, health safety, and fatigue are analyzed using virtual human simulation technologies.

The human error factors in the maintenance process are analyzed using the human error probability (HEP) based on the success likelihood index method- (SLIM-) analytic hierarchy process (AHP).

The psychological factors level of maintenance personnel is determined with an expert scoring.

The human factors for the entire RHM system are then evaluated using the interval method.

An application example is present, and the application results show that the approach can support the evaluation of the human factors in RHM.
