Evaluation of Human Machine Interface (HMI) on a Digital and Analog Control Room in Nuclear Power Plants Using a Fuzzy Logic Approach

Abstract

Nuclear Power Plants (NPPs) are nowadays facing a transition from analog to digital control rooms, mainly in the form of new interfaces for displaying sensor information as of Human Machine Interface (HMI) were one-sided, taking into consideration either the human or the machine perspective. The approach presented in the present article considers human machine interfaces met in nuclear power plants as a joint system, where the performance of the NPP operator is evaluated according to the cooperation level achieved with the machine. In particular, the purpose of this study is to provide a methodology to evaluate the degree of flexibility of an operator during the transition period from an analog to a digital system. The proposed methodology has been implemented by utilizing fuzzy logic inference and realized with the fuzzy toolbox embedded in Matlab software.

“…Different evaluation methods, of course, have been proposed to improve the performance of operators. For example, Lagari et al [161] use fuzzy logic approaches for evaluation, Lee and Cha [162], however, utilize 3D computational modeling for evaluation based on Virtual Reality (VR). Other evaluation approaches include human-in-the-loop evaluation [163], balancing principles [164], augmented reality-based evaluation [165], and so on.…”

“…A number of intelligent NPP interfaces have been developed. Lagari et al [30] and Nasiakou et al [31] provided fuzzy logic-based control interfaces. The intelligent design review system consists of several functions with some intelligence which has a cognitively oriented inference mechanism in addition to the traditional rule-based system elements shown in Figure 5.…”
