“…Previous quantitative researches regarding communication between NPP operators basically adapted Kanki and Foushee's speech-act coding scheme or employed a similar classification scheme [7,[9][10][11]. However, our focus is a quantitative analysis on the inquiry types of only the SS when the SS can obtain information from the CBP.…”

“…Therefore, a communication standard for operators in computerbased control rooms is required. In a conventional control room, a three-way communication method is recommended during inquiry/reply or command communications [7]. However, because SSs can acquire information from CBPs or personal displays, SSs are able to efficiently deal with emergency situations using less-dependent inquiry types such as an announcement or confirming question.…”

“…Kim et al investigated the distribution of communication patterns in a conventional control room and found that two types of communication were the most frequent: an inquiryreply type to recognize or identify symptoms of abnormal situations, and a command type to execute countermeasures [7]. These two types of communication can be seen as activities to share information at a boundary between cognitive functions of the SS and BO, as shown in Figure 1 (left).…”

With the development of computer-based control rooms including a computer-based procedure (CBP), shift supervisors (SSs) can directly access plant information through a CBP or personal displays instead of depending on other board operators (BOs) to obtain plant information. In relation to this change, we examined the characteristics of SS inquiry patterns in the computer-based control rooms of nuclear power plants during emergency situations. Operator behaviors and speech patterns were observed and analyzed through several experiments on simulated accident scenarios in a full-scope simulator for an advanced computer-based main control room. We found that the SS inquiry in the advanced control room had less dependency on the BOs, and that the inquiry patterns varied according to the operators and operating dates. From these findings, the necessity to establish communication standards under computer-based control rooms was discussed with some recommendations. Another requirement to reduce the cognitive workload of SSs was also discussed.Keywords: crew communication; computer-based control room; computer-based procedure; human error IntroductionRecently, there has been prompt research in developing computer-based systems, including human-system interfaces in the main control rooms of nuclear power plants (NPPs) [1,2]. O'Hara et al. introduced the characteristics of computer-based systems, which can integrate various types of information into a legible interface and present them to an individual [3]. For example, a computer-based procedure (CBP) allows operators to easily search or identify parameters or states of plants by presenting the relevant parameters in a given procedure. Because of this function of the CBP, an operator can operate power plants by simply following up the CBP rather than finding the parameters from instruments or indicators.On the other hand, the introduction of a CBP can influence the behaviors of the operating crew conducting the required operations based on the operating procedures. During emergency situations in a conventional main control room, a shift supervisor (SS) generally proceeds with emergency operation procedures (EOPs) and requests information from board operators (BOs) to obtain information relevant to the current plant states [4]. The SS also controls the plants

“…In the complex network environment network management must be able to collect the data of multiple sensors, collect the uncertain information standardization processing, integrate, evaluate, make the evaluation results in visual manner, and for auxiliary network managers to quickly make a decision; the problem of network security thus appears to be repaired [6]. Therefore, the concept of network security situation emerged as the time's requirement, and it can effectively integrate information of multiple sensors, the macro reaction of the current operation state of the whole network [7,8].…”

Along with the unceasing expansion of computer network scale, sharp growth of network user quantity, and various kinds of network security incidents also emerged in an endless stream, so computer networking faces severe challenges. At present, the research on network security is mainly concentrated on the research on intrusion detection method, but with the network's complexity and uncertainty increases, the research on network security situation is bound to become a trend. Research on network security situation warrants that the security state should be integrated into various safety factors for the whole dynamic response of the whole network, and to make timely and accurate prediction of the state of safety. This paper establishes the evaluation and prediction model of computer network security situation. After analyzing and summarizing the existing methods of some network security situation evaluation and prediction algorithm, this paper proposes a model for network security situation assessment and prediction of the trend of multi sensor data fusion.
