The Experimental Study on Verifying the Rationality and Weakness of THERP with an Example of Truck Refrigerant Filling Process

Abstract

Ming-Ming D, Guo-Qi Z

With an example of truck refrigerant filling process, an experimental method by E-prime was used to verify the analysis of human error probability in the refrigerant filling process by The Technique of Human Error Rate Prediction (THERP). The result of the experiment is basically in coincidence with the result of THERP. The weakness of THERP is that it calculates the human error, ignoring the cognitive process of the operation behavior.
