Description

  The present invention relates to a simulation evaluation apparatus that presents to a player whether or not a command executed by a player (trainee) is valid for past simulation results in a training simulation apparatus.

  In a conventional training simulation apparatus, a simulation is actually executed based on a command given by a player, and the analysis result is analyzed by analyzing the result from log data after all the executions are completed.

  In addition, in order to confirm the current data during training, two simulations are used to simulate current data during training by one simulation and simulated input from historical data that serves as a model for driving operations by the other simulation. There is a simulation device for comparing and displaying. As an example of such a device, a device relating to a training simulator device used for training the operation of a device such as a power plant is known (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 8-16092 (pages 4-5, FIG. 1)

  For example, in a training simulator that uses current status information display, area display, and the like, the player confirms the activity status of the group according to the executed command, and considers the next new command for the group. Therefore, when considering the next new directive, it is important to determine whether the implemented directive is a valid directive and how it will affect the final outcome, and know its effectiveness and impact. A hand was required.

  However, in the conventional training simulation device, for example, after the execution of the simulation is completed, the result is analyzed and confirmed from the log data, so how effective is the command executed at a certain point in time, Also, it is impossible to know in real time how much the final result is affected.

  In addition, the player inputs various commands during training. Therefore, when analyzing the simulation results after training and determining the effectiveness for each command entered by the player, the effectiveness is determined by isolating how much the various commands affect the simulation results. It is very difficult to judge.

  Further, in the training simulator device of Patent Document 1, it is possible to display the current status data during training, but whether the input performed by the player during training is a valid command in light of past data, or finally How much it affects the results.

  In addition, in the conventional technology, when a simulation is performed by repeating multiple commands, it is not clear what effect each command has on the result, and training on situation judgment and decision making is effective and efficient. There was a problem that it could not be implemented.

  In the training simulation apparatus, the present invention presents to a player in real time whether or not the command executed by the player is effective in light of past data and how it affects the final result. The purpose is to increase the effectiveness of training.

The simulation evaluation apparatus according to the present invention is:
A past data portion in which a set of simulation results based on a command input pattern implemented in the past and a command input pattern implemented in the past is stored;
Based on a command given from the outside, a similar command input pattern similar to the command given from the outside is searched from the past data section, and a similar simulation result based on the similar command input pattern and the similar command input pattern is extracted. A similar data search unit;
A similar command input pattern taken out by the similar data search unit, a hypothesis command creation unit that creates a hypothesis command input based on the command given from the outside,
A comparison display unit for comparing the prediction simulation result based on the hypothesis command input created by the hypothesis command creation unit and the similar simulation result extracted by the similar data search unit;
It is characterized by providing.

  By using the present invention, immediately after inputting a command, the effectiveness of the command and the effect on the final result can be presented to the player, and effective training is possible. In addition, more efficient training evaluation is possible as compared to analyzing the simulation result after training and determining the effectiveness of each command.

Embodiment 1 FIG.
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a functional block diagram according to the first embodiment of the present invention. FIG. 2 shows creation of a hypothesis command input pattern in the hypothesis command creation unit 10 of FIG. 1 when the input content is the same as a similar command input pattern but the command input time is different. FIG. 3 shows generation of a hypothesis command input pattern in the hypothesis command generation unit 10 of FIG. 1 when the input time is the same as that of a similar command input pattern but the input contents of the command are different.

  As shown in FIG. 1, a command is given from the outside to the simulation apparatus 1 and the similar data search unit 8. Here, the simulation apparatus 1 performs a simulation based on a command given from the outside, displays processing data, and outputs simulation log data as saved data in a file format. In order to perform these processes, the simulation apparatus 1 includes a simulation execution unit 2 and a log data creation unit 3.

  The simulation execution unit 2 executes a simulation based on a command given from outside and outputs processing data. During the execution of the simulation, the processing data is input to a display unit, for example, the region display unit 4 and the current status information display unit 5, and the contents regarding the processing data are displayed.

  The log data creation unit 3 creates log data based on the processing data output from the simulation execution unit 2 at an arbitrary time during the execution of the simulation or at the end of the simulation, and outputs the log data in a file format.

  The area display unit 4 displays an individual or a group appearing in the simulation in real time on the area map based on the processing data output by the simulation execution unit 2 during the simulation. The player can visually grasp the current state of the individual or group, when, where, and what action the individual or group appearing in the simulation is performing by displaying on the area display unit 4.

  The current state information display unit 5 displays detailed information such as individuals or groups appearing in the simulation in a text format or the like in real time based on the processing data output by the simulation execution unit 2 during the simulation. The player can grasp, by text information, the current state of the individual or group, when, where, and what action the individual or group appearing in the simulation is performing by displaying on the current state information display unit 5.

  The result data unit 6 accumulates the log data output from the log data creation unit 3 as a database.

  The result display unit 7 displays the log data accumulated in the result data unit 6. The result display unit 7 does not need to be displayed in real time like the region display unit 4 and the current status information display unit 5, and may display the result after the simulation ends, for example.

  The player gives the same command to the similar data search unit 8 as that given to the simulation execution unit 2. The similar data search unit 8 searches for a similar command input by referring to the data stored in the past data unit 9 based on the given command.

  Here, the past data section 9 is a database in which a set of command inputs executed in the past and simulation results based thereon are accumulated.

Here, regarding the command input searched by the similar data search unit 8, processing contents will be described in the case where the following conditions are used as search conditions.
(Condition 1) The command content and input order of similar command input and given command input are the same, but the command input time is different (see Fig. 2)
(Condition 2) The input time of the similar command input and the given command input is the same, but the command contents are different (see Fig. 3)

  It should be noted that completely matched ones are not subject to search because the simulation results are the same. The search condition is not limited to the above (Condition 1) and (Condition 2). The search condition may be set in advance in the similar data search unit 8 or may be input to the similar data search unit 8 from the outside.

  Further, when both of (Condition 1) and (Condition 2) are satisfied, for example, the higher cumulative point may be selected as a search result with reference to the cumulative point described later.

  When a new command is given, the similar data search unit 8 searches the past data unit 9 for a similar command input that satisfies the above condition. When a similar command input is retrieved from the past data unit 9, the similar data retrieval unit 8 extracts data of a similar command input pattern and a simulation result based on the similar command input pattern from the past data unit 9, and a hypothesis command creation unit 10 Output to.

  When a similar command input and a corresponding simulation result are input from the similar data search unit 8, the hypothesis command generation unit 10 receives a command given from the outside and a similar command input searched by the past data unit 8. A hypothetical subsequent command, that is, a hypothetical command input, is created from the above, and a simulation is performed in a process different from the simulation during training, and the log data is analyzed to predict the result.

  It should be noted that by performing simulation of another process for hypothesis command input, simulation load distribution can be performed, and a result can be predicted without being affected by the simulation being executed.

  Creation of a hypothesis command input in the hypothesis command creation unit 10 will be described. The hypothesis command generation unit 10 combines a command input pattern given by the player and a command after the point in time when a difference between a similar command input pattern retrieved from the past data unit 9 occurs and a command input pattern given by the player. Create a hypothesis command input pattern.

  First, the case where the similar data search unit 8 searches for (condition 1) will be described. As shown in FIG. 2, similar command input patterns retrieved from the past data portion 9 are command A, command B, command C, and command D. On the other hand, the command input patterns given to the simulation execution unit 2 are the command A, the command B, and the command C, and the command contents and the input order are the same as similar command input patterns.

  However, the input time of the command C differs between the given command input pattern and a similar command input pattern retrieved from the past data portion 9. Therefore, in the hypothesis command creation unit 10, as shown in FIG. 2, a hypothesis in which a command D of a similar command input pattern is input to the command input pattern given to the simulation execution unit 2 at the same input time as the similar command input pattern. Generate command input pattern.

  Next, a case where the similar data search unit 8 performs a search under (Condition 2) will be described. As shown in FIG. 3, similar command input patterns retrieved from the past data portion 9 are command A, command B, command C, and command D. On the other hand, the command input patterns given to the simulation execution unit 2 are the command A, the command B, and the command E, and the command input time is the same as a similar command input pattern.

  However, in the given command input pattern and the similar command input pattern retrieved from the past data portion 9, the command C is input in a similar command input pattern, but given to the simulation execution portion 2. In the command input, the command E is input, that is, the command content is different. Therefore, in the hypothesis command creation unit 10, as shown in FIG. 3, a hypothesis in which a command D of a similar command input pattern is input to the command input pattern given to the simulation execution unit 2 at the same input time as the similar command input pattern. Generate command input pattern.

  As shown in FIG. 1, for example, the simulation is started by a process different from the simulation apparatus 1 that is a training simulation, and the hypothesis command input pattern generated by the hypothesis command creation unit 10 is input. Similar to the training simulation, another process simulation is executed by the simulation apparatus 11 including the simulation execution unit 2 and the log data creation unit 3.

  The operation of the simulation apparatus 11 is the same as that of the simulation apparatus 1. However, the command input to the simulation apparatus 11 is a hypothesis command input pattern created by the hypothesis command creation unit 10, for example, a hypothesis command input pattern generated by the above (Condition 1) or (Condition 2). When simulation can be executed in a plurality of processes in the simulation apparatus 11, a plurality of hypothesis instruction input patterns are created in the hypothesis instruction creation unit 10 and given to the simulation apparatus 11 to perform parallel processing and execute the simulation. You may let them.

  Similar to the simulation apparatus 1, the log data creation unit 3 in the simulation apparatus 11 outputs processing data based on the simulation execution unit 2 in the simulation apparatus 11 as log data in a file format.

  The log data totaling unit 12 totals the log data output from the log data creating unit 3 of the simulation apparatus 11. The total result is a result prediction for the command input by the player.

  The comparison display unit 13 displays the simulation result corresponding to the similar command input pattern and the similar command input pattern used to create the hypothesis input command pattern and the hypothesis command input pattern from the hypothesis command creation unit 10 as well as log data. Log totaling results based on hypothesis command input patterns totaled from the totaling unit 12 are input in real time. Then, the result prediction based on the hypothetical command input pattern is compared with the past simulation result based on the similar command input pattern, and the effectiveness of the command input by the player is evaluated and displayed.

As an evaluation item for confirming the effectiveness of the command input by the player, for example, when an aircraft is assumed as an individual, the following evaluation items can be considered.
(Evaluation 1) An input command is effective when the number of sudden changes in the body posture of an aircraft or the like decreases or when the angle of sudden change is suppressed.
(Evaluation 2) The input command is effective when the remaining rate of the fuel mounted on the aircraft or the like is large.

  The effectiveness is converted into points for the above evaluation items, and the effectiveness of the input command is evaluated based on the accumulated points.

  The comparison display unit 13 displays the effectiveness of the command evaluated for the player who is being trained by combining the display items with the region display unit 4 and the current status information display unit 5. Examples of display items include information such as individual names and group names, parameter initial values such as the number of individuals and groups appearing in the simulation, simulation results based on hypothesis command input patterns, and similar commands retrieved in the past data section 9 The simulation result by the input, the effectiveness evaluation items shown above, the effectiveness by the hypothesis command input pattern, and the like.

  The data output from the log data totaling unit 12 is input to the accumulated data creating unit 14. The data output from the log data totaling unit 12 includes, for example, a hypothetical command input pattern and a simulation result for the hypothetical command input pattern, and the past data unit including the hypothetical command input pattern and the simulation result for the set as one set. The data to be registered in 9 is created.

  The data created by the accumulated data creation unit 14 is reflected in the past data unit 9 by being registered in the past data unit 9, and is used again in another training such as retraining.

  By adopting such a configuration, immediately after inputting a command, it is possible to show the player whether the command is effective in light of past data and the effect on the final result. Is possible. Compared to analyzing the simulation results after training and determining the effectiveness of each command, the effectiveness of each command is determined without analyzing log data after simulation, enabling efficient training evaluation. Become.

The hypothesis command creation unit 10 shows creation of a hypothesis command input pattern when the input content is the same as a similar command input pattern but the command input time is different. The hypothesis command creation unit 10 shows creation of a hypothesis command input pattern for a case where the input time is the same as that of a similar command input pattern but the command input content is different.
