Abstract
This paper proposes a modified GOMS (Goals, Operators, Methods, and Selection Rules) model based on CREAM (cognitive reliability and error analysis method) to decompose the tasks in complex scenarios, and calculate the mental workload of operators in nuclear power plants. The modified GOMS model has two parts, one is the task analysis based on the basic GOMS and CREAM, and the other is the complex scenarios analysis based on Bayesian networks. The modified GOMS method decomposes the tasks using hierarchical task analysis (HTA), and gets the operators combining the cognitive activities from CREAM and the values from the Multiple Resources. The complex scenarios analysis uses the COCOM (contextual control model) from CREAM to analyze complex scenarios, and it considers the 2-Tuple linguistic to evaluate the CPCs when the operators execute the tasks. The approach gets the prior probabilities of complex scenarios and uses Bayesian networks to obtain the control modes impact factor (CMIF). It calculates the mental workload by the modified approach in complex scenarios. A case study uses the modified GOMS model to decompose the hot shutdown, and calculate the mental workload in nuclear power plants. It compares the HTA and the modified GOMS model with the results of NASA-TLX. It verifies the modified GOMS model’s corrective and effective.
