Description

[Technical Field]

[0001] The present application relates to an operator performance evaluation system, an operator performance evaluation method, and an operator performance evaluation program. [Background technology]

[0002] Traditionally, performance evaluation of plant operators has been carried out by an experienced evaluator (such as an instructor) observing the operators as they operate actual plant equipment or simulators that simulate the plant during training, followed by debriefing such as interviews after the training is completed. However, this type of evaluation method relies to a certain extent on the evaluator's subjectivity, making quantitative evaluation difficult, and the use of the evaluation results has also been limited to providing feedback for the next training session.

[0003] Given this background, quantitative evaluation of operator performance is being considered. Quantitative performance evaluation allows for statistical analysis of the evaluation results. For example, it is expected that the results will be utilized in plant design and evaluation information, such as improving the ergonomic design of the plant (e.g., man-machine interface, operating procedures, training programs, etc.) and calculating the human error probability (HEP) in the plant and providing feedback to probabilistic risk assessment (PRA) / human reliability analysis (HRA). For example, Patent Literature 1 discloses a technology for quantitatively evaluating the operations of plant operators by acquiring feature data through sensor detection and comparing the obtained feature data with pre-registered data.

[0004] Furthermore, Patent Document 2 proposes an evaluation system that focuses on a cognitive process model that models human cognitive processes when evaluating operator performance. In this document, operator performance is checked against a cognitive process model that includes at least one of a detection process, a recognition / decision-making process, and a behavioral process, and the degree of task achievement of the operator is quantitatively evaluated by comparing each process with reference data.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-207670 [Patent Document 2] Japanese Patent Publication No. 2023-453 Summary of the Invention [Problem to be solved by the invention]

[0006] For example, in plants that require a high level of disaster prevention, such as nuclear plants, specific serious accident response equipment is installed to deal with specific serious accidents that occur. In the event of a specific serious accident, operators of the specific serious accident response equipment are required to act according to a scenario that combines the operation of the remote centralized monitoring and operation panel (ECP) installed in the emergency control room (ECR) and the operation of on-site control panels and auxiliary equipment at sites away from the emergency control room. In other words, operators not only remotely operate the remote centralized monitoring and operation panel in the emergency control room, but also, if necessary, go directly to the sites away from the emergency control room to carry out on-site work.

[0007] When evaluating the performance of operators of such specific serious accident response equipment, it is necessary to consider not only the operation of the remote centralized monitoring control panel (ECP) in the emergency control room, but also the movement of the operator outside the emergency control room and on-site operations. In the above-mentioned Patent Documents 1 and 2, performance evaluation is based on the actions of the operator operating a fixedly installed simulator device, so it is not possible to handle cases where the scenario assumed in the training includes the movement of the operator or on-site operations.

[0014] Hereinafter, several embodiments of the present invention will be described with reference to the accompanying drawings. However, the configurations described as the embodiments or shown in the drawings are merely illustrative examples and are not intended to limit the scope of the present invention.

[0015] First, the overall configuration of an operator performance evaluation system 1 will be described with reference to Fig. 1. Fig. 1 is a schematic diagram showing the overall configuration of an operator performance evaluation system 1 according to one embodiment, and Fig. 2 is a block diagram of the simulator device 8 and the operator performance evaluation device 10 in Fig. 1.

[0016] The operator performance evaluation system 1 is a system for evaluating operators who operate a plant 4. The plant 4 may be any plant that can be controlled by an operator operating a control device having a man-machine interface, but the following description will exemplify a nuclear plant.

[0017] Under normal circumstances, a nuclear power plant is controlled by operators operating a central control device located in a central control room, but in the event of a specific serious accident such as large-scale damage caused by a disaster such as an earthquake, it is expected that the central control room will become inoperable. Therefore, in preparation for the occurrence of such a specific serious accident, a nuclear power plant is provided with an emergency control room (ECR) 2 to continue plant operation in place of the central control room. The emergency control room 2 is equipped with an emergency control device (not shown), which is a remote centralized monitoring and operation panel (ECP) to control the plant 4 in place of the central control device.

[0018] In the event of a specified serious accident, operators control the plant by operating emergency control devices in the emergency control room 2. At this time, at the site 6 where the plant 4 to be controlled is located, situations may arise that require the operation of on-site operation panels, valves, etc. at the site 6, and in order to respond to these situations, operators are required to move from the emergency control room 2 to the site 6 as necessary to perform tasks. The operator performance evaluation system 1 can appropriately evaluate the performance of operators acting according to scenarios that include tasks that require such movement, using a simulator device 8 that simulates the emergency control device.

[0019] The operator performance evaluation system 1 includes a simulator device 8 and an operator performance evaluation device 10 for evaluating an operator based on performance data acquired from the simulator device 8.

[0020] The simulator device 8 is a device that simulates an emergency control device arranged in the emergency control room 2. The emergency control device that the simulator device 8 simulates is a control device equipped with a man-machine interface that is operated by an operator in the event of a specified serious accident. The simulator device 8 has a configuration equivalent to this kind of actual emergency control device. Furthermore, the simulator device 8 is configured to be able to reproduce a scenario that corresponds to the occurrence of a specified serious accident, and is therefore able to collect the operation details of the operator when the scenario is reproduced as performance data.

[0021] As shown in FIG. 2, the simulator device 8 includes a scenario reproducing unit 12 and a performance data detecting unit 14.

[0022] The scenario reproducing unit 12 is configured to reproduce a scenario corresponding to the occurrence of a specific serious accident. The scenario reproduced by the scenario reproducing unit 12 is set in advance so that the driver's actions are required across a first location and a second location that are different from each other. In this embodiment, the first location is the emergency control room 2 in which the simulator device 8 is installed, and the second location is a site 6 away from the emergency control room 2.

[0023] The specific content of the scenario reproduced by the scenario reproduction unit 12 is not limited, but is set so that, in the event of a specific serious accident, the tasks to be performed by the operator include, in addition to operating the emergency control devices in the emergency control room 2, at least one of moving outside the emergency control room 2 and working at the site 6. Such a scenario is reproduced, for example, by executing program data prepared in advance to correspond to the scenario. The manner in which the scenario is reproduced by the scenario reproduction unit 12 may be any manner that can be perceived by the operator, and may be, for example, performed by displaying a screen corresponding to the scenario on a display, or by audio instructions from a speaker or the like.

[0024] The performance data detection unit 14 is configured to detect data (hereinafter referred to as "performance data PD") related to the performance of the operator when a scenario is reproduced by the scenario reproduction unit 12. The performance data PD is detected corresponding to any of the processes constituting the cognitive process model M of the operator.

[0025] Here, we will explain in detail the operator's cognitive process model M. Figure 3 is a schematic diagram of the operator's cognitive process model M.

[0026] The cognitive process model M includes a detection process 20, a cognition and decision-making process 21, and a behavioral process 22. In the detection process 20, information is detected by the operator's sensory organs. Generally, humans have sensory organs corresponding to the five senses, such as sight, hearing, smell, and touch. However, during plant operation, the information perceived by operators is primarily visual and auditory, with the exception of specific events such as a fire occurring near the operator. For example, if a digital man-machine system is used in the aforementioned emergency control room 2, the majority of information perceived will be screen displays. Therefore, the following description focuses on visual information detection in the detection process 20, although information may also be detected using other sensory organs.

[0027] In the perception and decision-making process 21, the situation is recognized from the information detected in the detection process 20 (for example, visual information 23), and a decision is made to take action based on the recognized information. Here, in the perception process of an operator belonging to a team, the perception and decision-making made in the perception and decision-making process 21 is not performed by the operator alone, but as a team including a third party such as a team leader (team leader). Therefore, the perception and decision-making process 21 is influenced by the operator's own conversation log 24 and conversations 25 with third parties. In the behavior process 22, an action is taken based on the intention determined in the perception and decision-making process 21 (the results of the action are represented as an operation log 26 of the simulator device 8).

[0028] Fig. 4 is a configuration diagram showing an example of the performance data detection unit 14 in Fig. 2. Fig. 4 shows an example of the performance data detection unit 14 including a gaze data detection unit 27, an utterance data detection unit 28, and an operation record data detection unit 29 as a configuration for detecting performance data PD corresponding to the cognitive process model M of the driver.

[0029] The gaze data detection unit 27 is configured to detect gaze data as performance data PD corresponding to the detection process 20 in the cognitive process model M. As described above, in this embodiment, attention is focused on the gaze perceived by the human visual organs as information detected in the detection process 20. The gaze data detection unit 27 can detect gaze data as performance data PD by eye-tracking the viewpoint of such an operator.

[0030] The speech data detection unit 28 is configured to detect speech data, which is performance data PD corresponding to the cognitive-decision-making process 21 in the cognitive process model M. The speech data is voice data including the contents of the operator's speech, and the speech data detection unit 28 is configured as a recording device capable of recording the voice data. The speech data may include the contents of the speech of a third party in the team to which the operator belongs, in addition to the contents of the speech of the operator to be evaluated.

[0031] It is difficult to directly detect the thought content of the operator's cognition and decision-making in the cognition and decision-making process 21 of the cognitive process model M using sensors, but by treating such speech data as performance data PD, it becomes possible to quantitatively evaluate the thought content of the operator who is influenced by a third party. Note that a third party can broadly include anyone who has an influence on the operator's cognition and decision-making, such as a third-party driving commander.

[0032] The operation record data detection unit 29 is configured to detect operation record data, which is performance data PD corresponding to the behavioral process 22 in the cognitive process model M. The operation record data is data related to the operation history of the simulator device 8 by the operator when a scenario is reproduced, and is detected by acquiring an operation log of the simulator device 8 operated by the operator.

[0033] In this embodiment, the simulator device 8 having the above configuration includes a first simulator 30 and a second simulator 40, as shown in FIG.

[0034] The first simulator 30 is a main component of the simulator device 8 described above, and is the target for operation by the operator in the emergency control room 2. As described above, when a specific serious accident occurs, the operator's range of action spans the emergency control room 2 and the site 6, and the first simulator 30 can create the first performance data PD1 by detecting the performance data PD of the operator corresponding to the emergency control room 2, which is the first location within this range of action.

[0035] The second simulator 40, together with the above-mentioned first simulator 30, constitutes the simulator device 8, and is configured as a portable device such as a notebook PC or tablet. Therefore, the second simulator 40 can be carried by the operator and moved around, and the performance data detection unit 14 of the second simulator 40 can detect the performance data PD of the operator outside the emergency control room 2 within the above-mentioned range of the operator's activities (i.e., the work site 6, which is the second location, or the route of movement between the emergency control room 2 and the work site 6), and create the second performance data PD2.

[0036] The second simulator 40 has a main function of detecting the second performance data PD2 of the operator outside the emergency control room 2, and therefore can be configured as a portable device that can be carried by the operator and moved around, with relatively fewer functions than the first simulator 30, which is the main component. Therefore, by moving around while being carried by the operator, the second simulator 40 can detect the second performance data PD2 while moving from the emergency control room 2 to the site 6 and at the site 6.

[0037] Here, we will explain in detail some of the operational modes when the performance data detection unit 14 of the second simulator 40 detects the second performance data PD2. Fig. 5A is an example of a screen display when the second simulator 40 of Fig. 4 detects the second performance data PD2, and Fig. 5B is another example of a screen display when the second simulator 40 of Fig. 4 detects the second performance data PD2.

[0038] In these examples, when the operator moves from the emergency control room 2 and arrives at the site 6, a screen related to the task that the operator is to perform at the site 6 is displayed on the display of the second simulator 40. In FIGS. 5A and 5B, the target part of the plant 4 that is the target for performing the task is displayed in a schematic manner on the screen. The operator performs an operation according to the task on such a display screen (for example, by touching or clicking on a predetermined part), and the performance data detection unit 14 included in the second simulator 40 detects the operation content as second performance data PD2.

[0039] 5A, images of valves and pumps arranged in a system mimic as target parts of the plant 4 at the site 6 are displayed as icons on the touch panel provided in the second simulator 40. The operator carrying the second simulator 40 can select an appropriate icon by touching it on the touch panel displaying such a screen, thereby popping up the corresponding operating device and performing a task, thereby detecting the second performance data PD2.

[0040] 5B shows a hardware operator image on which icons corresponding to hardware operating devices such as switches and valve handles provided on a plant site operation panel (such as a power circuit breaker panel) located at the site 6 are displayed. The operator carrying the second simulator 40 touches and selects the appropriate location on the image on the touch panel displaying such a screen to perform a task, thereby detecting the second performance data PD2.

[0041] Furthermore, the performance data detection unit 14 included in the second simulator 40 can detect position information of the second simulator 40 (for example, GPS position information obtained by a GPS sensor) as performance data. Because the second simulator 40 is configured as a portable device, it may move around while being carried by an operator who acts according to a scenario, as will be described later. In such a case, the performance data detection unit 14 included in the second simulator 40 can detect performance data related to the movement state of the operator by detecting position information using a GPS sensor (not shown) or the like mounted on the second simulator 40. The detected position information is, for example, associated with the detection time and handled as second performance data PD2, thereby making it possible to evaluate the operator's movement time, on-site work time, and the like, based on the second performance data PD2.

[0042] In this way, the second simulator 40 is configured as a compact, portable device with a reduced device scale compared to the first simulator, which is the main component of the simulator device 8. This makes it possible to bring it into the emergency control room 2, which has limited space, and to allow operators who travel between the emergency control room 2 and the site 6 to carry it with them, thereby making it possible to suitably evaluate the performance of operators who act according to a scenario that involves travel between the emergency control room 2 and the site 6.

[0043] 2, the above-mentioned scenario reproducing unit 12 is provided in each of the first simulator 30 and the second simulator 40, thereby enabling a common scenario to be reproduced in each of the first simulator 30 and the second simulator 40. The above-mentioned performance data detecting unit 14 is provided in each of the first simulator 30 and the second simulator 40, thereby detecting the first performance data PD1 and the second performance data PD2. The first simulator 30 and the second simulator 40 also include storage units 32, 42 for storing the first performance data PD1 and the second performance data PD2 detected by the performance data detecting unit 14, respectively.

[0044] The first simulator 30 and the second simulator 40 also include synchronization control units 34 and 44, respectively. The synchronization control units 34 and 44 are configured to synchronously control the first simulator 30 and the second simulator 40. In the synchronization control, in each of the first simulator 30 and the second simulator 40, synchronization of the progress of the scenario reproduced by the scenario reproduction unit 12 is performed, and the performance data PD stored in each of the storage units 32 and 42 is shared.

[0045] In this embodiment, the synchronization control by the synchronization control units 34, 44 can be performed when the first simulator 30 and the second simulator 40 are wired connected by a communication cable 35, as shown in Fig. 1. However, if the first simulator 30 and the second simulator 40 can be connected wirelessly, the communication cable 35 is not necessary, and the synchronization control may be performed at any timing.

[0046] Next, we will explain the configuration of the operator performance evaluation device 10. The operator performance evaluation device 10 includes a first performance data acquisition unit 50, a second performance data acquisition unit 52, an evaluation data creation unit 54, an evaluation unit 56, and an output unit 58.

[0047] The first performance data acquiring unit 50 is configured to acquire the first performance data PD1. In this embodiment, the first performance data acquiring unit 50 accesses the first simulator 30 of the simulator device 8, and thereby acquires the first performance data PD1 detected by the performance data detecting unit 14 included in the first simulator 30.

[0048] The second performance data acquiring unit 52 is configured to acquire the second performance data PD2. The second performance data PD2 is detected by the performance data detecting unit 14 provided in the second simulator 40 of the simulator device 8, and is stored in the storage unit 32 provided in the first simulator 30 by performing synchronization control between the first simulator 30 and the second simulator 40 as described above. Therefore, the second performance data acquiring unit 52 accesses the first simulator 30 to acquire the second performance data PD2 stored in the storage unit 32 (i.e., the second performance data PD2 detected by the second simulator 40 is acquired via the first simulator 30).

[0049] The second performance data acquisition section 52 may directly acquire the second performance data PD2 from the second simulator 40 by accessing the second simulator 40 that detects the second performance data PD2.

[0050] The evaluation data creation unit 54 is configured to create evaluation data ED based on the first performance data PD1 acquired by the first performance data acquisition unit 50 and the second performance data PD2 acquired by the second performance data acquisition unit 52. The evaluation data ED may be created corresponding to each process constituting the cognitive process model M. As described above, the performance data PD contains at least one of gaze data detected by the gaze data detection unit 27, speech data detected by the speech data detection unit 28, and operation record data detected by the operation record data detection unit 29. The evaluation data creation unit 54 analyzes the performance data PD containing such a mixture of various data to determine whether the data corresponds to the detection process 20, the cognition / decision-making process 21, or the behavioral process 22 constituting the cognitive process model M, and associates the determination result with the scenario and task from which the performance data PD was acquired, thereby creating the evaluation data ED.

[0051] The evaluation unit 56 is configured to evaluate the operator based on the evaluation data ED created by the evaluation data creation unit 54. The evaluation by the evaluation unit 56 may be performed based on, for example, a judgment algorithm prepared in advance. The judgment algorithm is an algorithm for identifying an error code from the evaluation data ED. For example, the judgment algorithm can identify an error code from the evaluation data ED by associating an error mode related to at least a part of each process constituting the cognitive process model M with a judgment criterion corresponding to the error mode.

[0052] The output unit 58 is configured to output the evaluation result by the evaluation unit 56. The manner in which the evaluation result is output is not particularly limited.

[0053] Next, the operator performance evaluation method implemented by the operator performance evaluation system 1 having the above configuration will be specifically described using an actual scenario as an example. Fig. 6 is a flowchart showing each step of the operator performance evaluation method according to one embodiment in association with the operator's actions according to the scenario, and Figs. 7A to 7E are schematic diagrams showing the operation of the operator performance evaluation system 1 corresponding to each step in Fig. 6.

[0054] In the following embodiment, a case will be described in which an operator acts according to a scenario in which tasks 1 to 3 are performed in order, as an example of a scenario reproduced by the scenario reproduction unit 12 of the simulator device 8. In this scenario, it is specified that task 1, which should be performed in the emergency control room 2, task 2, which should be performed at the site 6 after task 1, and task 3, which should be performed in the emergency control room 2 after task 2, are performed in that order. Such a scenario is merely an example, and is not limited as long as at least some of the tasks included in the scenario involve movement of the operator.

[0055] First, the scenario reproduction unit 12 included in the simulator device 8 of the operator performance evaluation system 1 starts reproducing the scenario (step S20). When the scenario is reproduced, the operator first performs task 1, which is the first task specified among the multiple tasks included in the scenario (step S10). As described above, task 1 is a task that should be performed in the emergency control room 2, so in step S10, the operator performs task 1 using the first simulator 30 in the emergency control room 2, as shown in FIG. 7A.

[0056] When the first simulator 30 is operated by the operator in step S10, the performance data detection unit 14 of the first simulator 30 detects the behavior of the operator as first performance data PD1 (step S21) on the operator performance evaluation system 1 side. The performance data detected by the performance data detection unit 14 is stored as the first performance data PD1 in the memory unit 32 of the first simulator 30.

[0057] When task 1 is completed, the operator moves from the emergency control room 2 to the site 6 to carry out the next task 2 included in the scenario (step S11). As described above, task 2 is predefined in the scenario as a task to be carried out at the site 6. At this time, the operator moves while carrying the second simulator 40, which is a portable device among the simulator devices 8, as shown in FIG. 7B (i.e., the second simulator 40 is taken out of the emergency control room 2 by the operator).

[0058] At this time, in the operator performance evaluation system 1, the performance data detection unit 14 detects second performance data PD2 in the second simulator 40 that is carried by the operator while moving (step S22). Specifically, the performance data detection unit 14 of the second simulator 40 detects, as second performance data PD2, location information of the moving operator using, for example, a GPS sensor. The performance data detected by the performance data detection unit 14 of the second simulator 40 is stored in the storage unit 42 as the second performance data PD2.

[0059] Subsequently, the operator who has arrived at the site 6 performs task 2 at the site 6 (step S12). In step S12, the operator performs task 2 at the site 6 using the second simulator 40 that the operator carries out, as shown in FIG. 7C. At this time, the second simulator 40 displays a screen corresponding to task 2, as described above with reference to FIGS. 5A and 5B, so that the operator can carry out task 2.

[0060] At this time, on the operator performance evaluation system 1 side, the performance data detection unit 14 of the second simulator 40 carried by the operator detects the second performance data PD2 (step S22). The performance data detected by the performance data detection unit 14 is stored in the memory unit 42 of the second simulator 40 as the second performance data PD2.

[0061] When task 2 is completed, the operator moves from the site 6 to the emergency control room 2 to perform the next task 3 included in the scenario (step S13). As described above, task 3 is predefined in the scenario as a task to be performed in the emergency control room 2. At this time, the operator moves again carrying the second simulator 40, as shown in FIG. 7D (i.e., the operator takes the second simulator 40 back from the site 6).

[0062] At this time, in the operator performance evaluation system 1, the performance data detection unit 14 detects second performance data PD2 in the second simulator 40 that is carried by the operator while moving (step S22). Specifically, the performance data detection unit 14 of the second simulator 40 detects, as second performance data PD2, location information of the moving operator using, for example, a GPS sensor. The performance data detected by the performance data detection unit 14 of the second simulator 40 is stored in the storage unit 42 as the second performance data PD2.

[0063] Next, the operator who has returned from the site 6 to the emergency control room 2 performs a synchronization operation of the simulator device 8 (step S14). In step S14, the operator connects the second simulator 40 that he has brought back from the site 6 to the first simulator 30 installed in the emergency control room 2, thereby performing a synchronization operation.

[0064] When the synchronization operation is performed by the operator, on the operator performance evaluation system 1 side, synchronization control is executed by the synchronization control unit 34 of the first simulator 30 and the synchronization control unit 44 of the second simulator 40 (step S23). As described above, the synchronization control synchronizes the progress of the scenarios in the scenario reproduction units 12 of the first simulator 30 and the second simulator 40, and transfers the second performance data PD2 accumulated in the memory unit 42 of the second simulator 40 to the memory unit 32 of the first simulator 30. As a result, the memory unit 32 of the first simulator 30, which is the main component of the simulator device 8, manages the first performance data PD1 and the second performance data PD2 in an integrated manner.

[0065] Next, the operator performs the next task 3 in the emergency control room 2 according to the scenario (step S15). In step S15, similar to the above-mentioned task 1, the operator performs task 3 using the first simulator 30 in the emergency control room 2. At this time, on the operator performance evaluation system 1 side, the performance data detection unit 14 included in the first simulator 30 detects the behavior of the operator operating the first simulator 30 as first performance data PD1 (step S24). The performance data detected by this performance data detection unit 14 is accumulated as the first performance data PD1 in the memory unit 32 included in the first simulator 30.

[0066] Then, when the scenario to be executed on the operator side is completed in this way (step S16), on the operator performance evaluation system 1 side, the operator performance evaluation device 10 acquires performance data PD from the simulator device 8 (step S25), as shown in Fig. 7E. Specifically, the first performance data acquisition unit 50 acquires the first performance data PD1, and the second performance data acquisition unit 52 acquires the second performance data PD2.

[0067] Next, the evaluation data creation unit 54 creates evaluation data ED based on the first performance data PD1 and the second performance data PD2 acquired in step S25 (step S26). Next, the evaluation unit 56 uses the evaluation data ED created in step S26 to perform a performance evaluation of the series of actions of the operator in accordance with the scenario (step S27). Then, the evaluation result by the evaluation unit 56 is output by the output unit 58 (step S28).

[0068] As described above, according to the above embodiment, the performance of the operator when performing a task using the simulator device 10 in the emergency control room 2 is acquired as the first performance data PD1. Furthermore, performance related to at least one of the movement of the operator between the emergency control room 2 and the site 6 and the task performed by the operator at the site 6 is acquired as the second performance data PD2. By evaluating the performance of the operator based on both the first performance data PD1 and the second performance data PD2 acquired in this manner, it is possible to appropriately evaluate the performance of the operator acting according to a scenario involving travel between the emergency control room 2, which is a first location, and the site 6, which is a second location.
