Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for setting simulation conditions (hereinafter simply referred to as conditions) and a simulation result (hereinafter simply referred to as simply "conditions") in a simulation system in which the behavior of a model relating to a certain problem is calculated on a computer under various conditions. Regarding the display method of (Result),
In particular, the problem is that it takes a long time to execute one simulation (hereinafter, simply executed) for one condition, and thus it is difficult for the user to repeat the simulation interactively. The present invention relates to a method of setting conditions and a method of displaying results in a simulation suitable for a simulated system (hereinafter, simply referred to as a system).

[0002]

2. Description of the Related Art Conventionally, interactively used systems are
It was used as follows. That is, the user first gives a certain condition to the system and causes the simulation to be executed for that condition. By seeing the result,
The user next considers the conditions he wants to give to the system. In many cases, the user sets the next condition by changing the values of some of the plurality of parameters that constitute the condition at the time of the previous execution. Then, the simulation is executed again for the changed conditions. And see the results. The above process was repeated many times interactively.

[0003]

By the way, according to the above-mentioned prior art, when the time required for one execution is long, the user who sees the result waits for a long time until the processing is completed each time. Therefore, there is a problem that it is not possible to interactively perform a plurality of simulations under various conditions.

An object of the present invention is to solve such a conventional problem, and even when it takes a very long time to execute a single operation, a user who looks at the result does not have to wait for a long time to execute a simulation. It is to provide a condition setting method and a result display method and system in a simulation capable of interactively executing a plurality of executions.

[0005]

In order to achieve the above object, the condition setting and result displaying method in the simulation according to the present invention is (a) setting and setting a plurality of conditions based on the intention of the user who sees the result. The simulation is executed for the specified conditions, and the obtained results are edited and displayed.

In addition, (b) the setting of the above conditions determines the range of values for executing the simulation for each of the plurality of parameters constituting the conditions, based on the intention of the user who views the results.

Further, (c) the above condition is set by stepping the range of values described in (b) above for each of a plurality of parameters constituting the condition based on the intention of the user who sees the result. It is also possible to divide while changing the value and determine a plurality of parameter values when executing the simulation.

(D) For setting the above conditions, one of the plurality of parameters constituting the condition is selected from the plurality of values described in the above (c), and the plurality of conditions are set. Create and assign the execution priority to each of the created conditions based on the user's intention to view the results.

Further, (e) the above-mentioned condition setting is inferred by using a rule that describes the relationship between the user's intention regarding the condition and the condition setting processing corresponding to these.
Execute the processes of (b), (c), and (d).

In addition, (f) the above-mentioned conditions are set by setting a plurality of conditions based on the intentions of a plurality of users.

(G) In addition to editing and displaying any of the results for a plurality of conditions for which the simulation was actually executed, the result display means displays a condition different from the above condition. An approximate value of the result is calculated by interpolating the result of the condition of the neighborhood which has already been obtained by the execution, and the edited value is displayed.

Further, (h) the executing means corrects the condition based on the intermediate result of the simulation during the execution, and continues the simulation for the corrected condition.

The system according to the present invention also stores (i) a condition setting data file for storing a given user's intention, and a condition setting rule in which the relationship between the user's intention and conditions is described. The condition setting rule file, the contents of the above condition setting data file and the contents of the above condition setting rule file are read, a plurality of conditions reflecting the user's intention are created, and the created conditions are accumulated. A processing unit, a condition file that stores the created plurality of conditions, a data file that stores data used for simulation, the contents of the condition file and the contents of the data file are read, and a simulation is performed for the read plurality of conditions. Execution processing unit that executes collectively and accumulates results, result file that stores the results of the above simulation , Reads the contents of the result file comprises a result display processing unit for displaying edit and interpolating the results in accordance with an instruction of the user.

[0014]

In the present invention, the condition setting means adds the user's intention, the range of the value of each parameter constituting the condition, the step size, to the intention data concerning the condition input by the user.
By applying a rule that describes the relationship between the execution priority and the execution priority and performing inference, a plurality of conditions for executing the simulation are determined. That is, first, the range of values is determined for each of the plurality of parameters that form the condition, based on the user's intention. Next, based on the user's intention, the above range of values is divided by the step size to determine a plurality of values for each parameter. Finally, create multiple conditions by selecting one from the multiple values determined for each parameter, and set the execution priority among the created multiple conditions according to the user's intention. Make a decision based on As a result, a plurality of conditions that the user wants to see, that is, the user's intention is reflected, that is, according to the parameter range, the step size, and the priority order, are collectively created before execution. Can be set.

The condition setting means uses data input by a plurality of users as the intention data regarding the condition. That is, a plurality of conditions are created by assigning a priority to each of a plurality of users and applying a rule to the intent data regarding the condition input from each person while considering the priority and inferring the rule. To do. Accordingly, it is possible to collectively create a plurality of conditions in advance so that the intentions regarding the conditions of the plurality of users are adjusted before the execution.

The executing means executes the simulations for the plurality of conditions created by the condition setting means in order from the highest priority, and accumulates the results. At this time, during the execution, the results of the simulation are monitored, and when the difference between the results of the two conditions where the parameter values are adjacent to each other is a certain value or more, an intermediate parameter between the two values of the above parameters is monitored. Create a new condition with a value and run the next simulation for this condition. On the other hand, if the difference between the results of the two conditions is less than a certain value, then do not execute the simulation for all the two conditions that have the same parameter values as the conditions executed later. To This allows you to skip the condition or set the parameter value if the step size of the parameter value is too small and the simulation is not meaningful during the execution of multiple preset conditions. If you expect the result to be too coarse because of too many steps,
Since it is possible to add a condition having a parameter value in the middle of the conditions, it is possible to obtain a more homogeneous result as a whole.

Further, the result display means displays the results of execution of a plurality of conditions according to the user's instruction. That is, first, the user instructs the conditions. When the simulation is actually performed for the designated condition and the result is obtained, the result for this condition is edited and displayed. The above processing does not include execution. This allows the user to interactively select and view the results for a plurality of conditions. If the condition instructed by the user does not correspond to the condition in which the simulation is actually performed, the interpolation calculation of the actual result for the neighboring condition having the parameter value similar to the instructed condition is performed. The interpolation result is edited and displayed as an approximate value of the result under the designated condition.
As a result, the user can know the approximate value of the result under the condition that the simulation is not actually performed.

FIG. 3 is a processing flowchart of the system showing an embodiment of the present invention.

When the system is started up, the control processing unit 14 first starts up the condition setting processing unit 11. The condition setting processing unit 11 displays guidance on the screen of the display device 23 and requests the user to input data for creating condition setting data. The condition setting processing unit 11 receives an instruction from the user for this request via the keyboard and stores it in the condition setting data file 16 (step 31).

Next, the condition setting processing unit 11 obtains the simulation characteristic data from the characteristic data file 15, the condition setting data from the condition setting data file 16, and the condition setting rule from the condition setting rule file 17. , Respectively, to create a plurality of conditions reflecting the user's intention (step 32).

When the processing in the condition setting processing unit 11 is completed, the control processing unit 14 activates the execution processing unit 12. The execution processing unit 12 inputs the conditions from the condition file 18 and the data from the data file 19, respectively, and collectively calculates all the inputted conditions (step 34). Then, the result is output to the result file 27 (step 35).

When the processing in the execution processing unit 12 is completed, the control processing unit 14 activates the result display processing unit 13. The result display processing unit 13 displays a guidance on the screen of the display device 23 and requests the user to input the condition for which the user wants to see the result. The result display processing unit 13 receives an instruction from the user for this request via the keyboard 24, and edits and displays the result corresponding to the input condition. When the conditions instructed by the user are not actually simulated, other results obtained at that time are interpolated to calculate and display an approximate value (step 36).

FIG. 4 is an internal block diagram of the characteristic data file 15 in FIG.

The required time t41 per simulation is stored in advance in the characteristic data file 15. The required time t does not need to be a strict value, and may be a value that is a rough guide.

FIG. 5 is an internal block diagram of the condition setting data file 16 in FIG.

This file is input by the user,
The end time d51 of the entire simulation and the user's intention 52 regarding the conditions are stored. The end deadline time d is the time at which the execution process must be terminated,
That is, it represents the time when the user wants to start viewing the result. In addition, the user's intention 52 regarding the condition is that the range of the value of each parameter forming the condition is
The information regarding the interval between the parameter values and the information regarding the priority of the value of the parameter to be simulated are stored.

For example, the data regarding the range of the parameter value is described as (1) (I want to see the result when the value of the parameter a is large). Further, the data regarding the interval of the value of the parameter is described as (2) (I want to see the result in detail about parameter a) or (3) (I want to see the result roughly about parameter a). In addition, data regarding the priority of the value of the parameter is (4) (I would like to see the result for parameter a = value x) (5) (I want to see the result for parameter a = value y) Described in. Also, by combining the above data, it is also possible to describe as (6) (I would like to see the result in detail where the value of parameter a is large).

Further, in addition to the data described directly for specific parameters as in the above (1) to (6),
For example, data for which specific parameters are not directly specified, such as (7) (I want to increase sales), can be stored. This kind of data is converted into data in the form in which specific parameter names such as (1) to (6) are described by inference using a condition setting rule in the condition setting processing unit.

Further, the condition setting file 16 can store intention data 52 input by a plurality of users. In that case, data representing the distinction of the user is added to each of the data shown in (1) to (6) above. That is, for example, in the case of the data of (2) above, it is described as (8) (I want to see the result in detail for parameter a) (User A).

FIG. 6 is an internal block diagram of the condition setting rule file 17 in FIG.

The IF-THEN format rule 61 is stored in this file. The IF part 62 of the rule stores a description corresponding to the user's intention 52 regarding the condition described in FIG. In addition, in the THEN part 63 of the rule,
The description of the action to be taken when the condition of the corresponding IF unit 62 is satisfied is stored.

As a rule, a rule for defining a range of conditions, a rule for determining an interval of conditions within the defined range, and which of the determined conditions should be executed for the simulation is determined. The rules and rules for doing this are stored.

The respective rules are, for example, (9) IF (I want to see the result when the value of parameter a is large) THEN (shift the range of parameter a upward) or (10) IF (details about parameter a I want to see the result) THEN (decrease the step size of parameter a) Or (11) IF (value = x for parameter a I want to see the result by all means) THEN (value for parameter a = x Priority is increased ).

Further, rules for converting data in which parameters are not specifically specified into data in which parameters are described are, for example, (12) IF (to increase sales) THEN (for parameter a) Where the value is large
(I want to see the result about) (I want to see the result about parameter a in detail).

Further, when the data of the user's intention 52 regarding the condition is input from a plurality of users and the data indicating the distinction of the user is added to each data, the rule is, for example, 13) IF (I want to see the result for a large value for parameter a) (User B) THEN (shift the range of parameter a upward)
(Priority 1) is described. That is, the priority is assigned to the conclusion part of the rule corresponding to the user.

FIG. 7 shows the condition setting processing unit 1 according to the present invention.
It is a processing flowchart of 1.

The condition setting processing section 11 displays guidance on the screen of the display device 23 and requests the user to input data for creating condition setting data. The condition setting processing unit 11 receives an instruction from the user for this request via the keyboard. The data to be input are the time d51 of the end deadline of the entire simulation and the user's intention 52 regarding the conditions. Then, these are stored in the condition setting data file 16 (step 71).

After this, the time t required for one execution is read from the characteristic data file 15, and the simulation end deadline time d is read from the condition setting data file 16. Then, by subtracting the current time from the time d of the end deadline, the upper limit T of the time for execution is calculated (step 72). This T is simulated 1
The upper limit N of the number of simulations expected to be performed within the time limit is calculated by dividing by the required time t per time (step 73).

Next, the condition setting processing section 11 inputs the condition setting data from the condition setting data file 16 and the condition setting rule from the condition setting rule file 17 (step 74). Then, the IF section finds a rule that matches the condition setting data, that is, an applicable rule (step 75). When the applicable rule is found, the operation described in the THEN part of the above rule is executed, and the execution result is stored inside (steps 76 and 77). This process (steps 75 to 7)
Repeat 7) until there are no applicable rules.

There are no applicable rules (step 7)
6), the N stored conditions are output to the condition file 18 in descending order of priority (step 78).

FIG. 15 is a schematic diagram showing how a plurality of conditions for executing the simulation are determined.

The figure shows the case where there are two parameters constituting the condition. FIG. 15A is a schematic diagram showing how the condition range is determined. As shown in the figure, first,
A region 151 surrounded by a rectangle is determined by applying the rule. FIG. 10B is a schematic diagram showing how to determine a point 152 to be actually simulated within the range 151 of the determined condition. As shown in the figure, the step size is changed within the range 151 by applying a rule, and each point 152 to be simulated is determined. Next, FIG.
[Fig. 6] is a schematic diagram showing how the execution priority order is determined within the determined conditions of each point. By applying the rule, the execution priority 153 is assigned to each point 152.

FIG. 8 is an internal block diagram of the condition file 18 in FIG.

Now, it is assumed that the condition is composed of n parameters 81. As shown in the figure, in the condition data file 18, the condition for one simulation is expressed as one record 82. Therefore, in one record 82, n parameters 81 constituting the condition are recorded. The file 18 stores N records, which is the number of times the simulation is performed.

FIG. 9 shows the data file 19 shown in FIG.
FIG.

In this file, master data 91 used at the time of execution is stored.

FIG. 10 is a processing flowchart of the execution processing unit 12 in FIG.

The execution processing unit 12 first checks whether or not the end time d will be exceeded when one simulation is newly executed by adding the required time t per simulation to the current time.
Then, when it is expected to exceed, the processing is ended (step 101). If the end time d is not likely to be exceeded, it is checked whether or not the condition file 18 has a condition for performing the next simulation (steps 101 and 102). If there is a condition for the simulation to be executed next time, the condition is read from the condition file 18 (steps 102, 10).
3). If the condition does not exist in the file, the process ends (step 102).

Next, the newly read condition is calculated using the data read from the data file 19 (step 104). Then, the execution result is
Write to the result file 110 (step 105). Then, the process returns to step 101. The above processing (steps 101 to 105) is repeatedly executed.

Further, the executing means writes the result in the result file 110 in step 105 and monitors the contents of the intermediate result in the file. Then, when the difference between the results of the two conditions in which the parameter values are adjacent to each other is a certain value or more, a condition having a parameter value intermediate between the two values is newly created for the parameter.

That is, it is assumed that the condition is composed of two parameters X and Y, and the condition at this time is represented as (X, Y). Now, there are two kinds of conditions (x1, y1) and (x2, y2), and x1 and x2
Are equal in value. It is assumed that y1 and y2 are adjacent values. Then, if the difference between the result values z1 and z2 for each condition is larger than a preset constant value, the value of the parameter Y is (y1 + y2).
A new condition of / 2 is created. Then, the next simulation is executed under this condition.

On the contrary, when the difference between the two results z1 and z2 is smaller than the predetermined constant value, the simulation is not executed thereafter for the condition that the value of the parameter Y is y2.

FIG. 11 shows the result file 11 in FIG.
It is an internal block diagram of 0.

Now, the result of one simulation is m
It is assumed that it is composed of individual data 111. As shown in the figure, in the result data file 110, the result of one simulation is represented as one record 112. Therefore, one record 112 records n pieces of data 111 constituting the condition. Then, the above-mentioned records are stored in the file 110 by M times, which is the number of times of actually executed simulations.

FIG. 12 shows the result display processing unit 1 in FIG.
It is a processing flowchart of 3.

First, the result is input from the result file 110 (step 121). Then, the result of the first simulation is output to the display device 23 and displayed (step 122).

Next, the guidance is displayed on the display device 23 to request the user to give an instruction, and the instruction from the user is input (step 123). The instruction input by the user is a termination instruction or a condition under which the user wants to see the result. When the instruction from the user is finished, the process is finished (step 124). When the instruction from the user is a condition, if the result of the instructed condition is in the result file, the result is displayed (steps 125 and 126). If the result under the condition instructed by the user is not in the result file, the interpolation calculation is performed using the result for the condition having a parameter value similar to the condition instructed by the user. Then, the result of the above interpolation calculation is displayed as an approximate value of the result under the designated condition (steps 125, 12).
7).

FIG. 13 is an example of a display screen output by the result display processing unit 13 to the display device 23.

On the screen of FIG. 13, a list of conditions actually performed is displayed in the lower part. The execution number 131 and the parameter 132 of the condition at that time are displayed there. In the lower row, the maximum value 133 and the minimum value 134 of each parameter of all executed conditions are displayed.

The user can see the result of the desired case by inputting the execution number in the simulation number column 138 in the upper part of the screen. The resulting value is displayed in the results column 136. Further, each parameter of the condition at that time is displayed in the field 135.

The user also selects the condition parameter column 13
It is also possible to directly enter a value in 5. In this case, the result is displayed in the result column 136 if it is actually performed under the condition that matches the input condition. Otherwise, the approximate value calculated by the interpolation calculation using the actual result is displayed in the result column 136. At this time, the interpolation presence / absence column 137 in the middle part of the screen blinks to notify the user that the interpolation calculation has been performed.

FIG. 14 is a diagram showing an outline of the result interpolation processing in the result display processing unit 13.

FIG. 14 shows the case where there are two parameters. The two parameters are X and Y respectively
And Now, the condition specified by the user is (x, y) 1
41 and consider that the result P under this condition is approximately obtained. Four neighboring conditions (x1, y1) 142, (x2, which have parameters similar to the condition (x, y),
y1) 143, (x1, y2) 144, (x2, y2)
As a result of 145, it is assumed that A, B, C, and D are obtained, respectively. Here, x1 <x <x2, y1 <
y <y2. At this time, if bilinear interpolation is used as the interpolation method, the approximate value of P is calculated by the following equation.

[0072]

## EQU1 ## P = {A (x2-x) (y2-y) + B (x-x1) (y2-y) + C (x2-x) (y-y1) + D (x-x1) ( y-y1)} / {(x2-x1) (y2-y1)} (Equation 1) In this embodiment, the condition setting processing unit uses a rule that describes the relationship between the user's intention and the condition. By applying information about the intent regarding the conditions entered by the
Since the condition range, step size, and priority order are determined, a plurality of conditions reflecting the user's intention can be collectively created before execution. In addition, since rules are used to make inferences while considering the priority of the intent data related to the conditions input from multiple users, it is possible to combine multiple conditions in which the intent related to the conditions of multiple users has been adjusted. Can be created.

Further, the execution processing section executes the simulations in order from the one with the highest priority, and while the results are being accumulated, the intermediate results of the simulation are monitored and the conditions are added and deleted. As a more uniform result can be obtained.

Further, the result display processing section only edits and displays the result of the condition instructed by the user. Since this process does not include execution, one execution takes a very long time. Even in the case of a problem, the user can interactively select and view the results for a plurality of conditions.
Also, if the condition instructed by the user does not actually correspond to the condition under which the simulation was performed, the results are interpolated for similar conditions, and as an approximate value of the results under the instructed condition, Since the interpolation result is displayed, the user can approximately know the result under the condition that the simulation is not actually performed.

[0075]

According to the present invention, a rule describing the relationship between the user's intention and condition range, step size, and priority is
The range, step size, and priority of the condition are determined by applying the information about the intent regarding the condition input by the user who sees the result.
It is possible to collectively create multiple conditions that reflect the user's intention. In addition, data of intention regarding conditions is input from multiple users, priority is given to each user, and the above priority is taken into consideration in the data of intention regarding conditions input by each person. However, since the range of conditions, the step size, and the priority order are created by applying the rules and inferring them, a plurality of users may be adjusted in advance before the execution so that the intentions regarding the conditions of a plurality of users are adjusted. The conditions of can be created collectively.

Also, the simulation is executed in order from the condition with the highest priority, and the results of the simulation are monitored while the results are being accumulated. If there is a certain value or more, create a new condition with an intermediate parameter value between the two values for the above parameters, and execute the next simulation for this condition. In the case of, of the above two conditions,
For all the conditions that have the same parameter values as the conditions executed later, we will not execute the simulation in the future, so
In the middle of execution, when the step size of the parameter value is too small and it is expected that the simulation does not make sense, if the condition is skipped or the step size of the parameter value is too large and the result becomes too coarse, When expected,
Conditions with intermediate parameter values can be added, and a more homogeneous result can be obtained as a whole.

Further, when the simulation is actually performed for the condition designated by the user and the result is obtained, the result of this condition is simply edited and displayed. Execution is not included, so
Even if it takes a long time to execute once, the user can interactively select and view the results for a plurality of conditions. If the condition instructed by the user does not actually correspond to the condition under which the simulation is performed, the result of the condition similar to the instructed condition is interpolated and the specified condition is satisfied. Since this interpolation result is edited and displayed as an approximate value of the result, the user
It is possible to obtain an approximate result about the condition under which the simulation is not actually performed.
