(Embodiment) An embodiment of the present invention will be described in detail below with reference to the drawings.

First, the configuration of the design procedure support apparatus according to the present invention will be explained with reference to FIG.

The input device 1111 is composed of a keyboard or the like, and outputs parameters or values related to the design procedure by performing key operations. The storage device ff113 stores information regarding the design procedure, and is configured by dividing each frame into frames for each parameter necessary for the design.In the frame, other parameters necessary to obtain the value of the parameter are stored. remembered. That is, information (parameters) for each frame is arranged and stored in a mutually related hierarchical structure.

Here, the parameters necessary for design are, for example, 0-40
This refers to performance indicators such as time during 0rA acceleration, and specifications and concepts of destinations, roadways, etc. for obtaining those performance indicators.

The control txJ device 15 is connected to the input device @11 and is also connected to the storage device 13, and reads out the information regarding the design procedure stored in the storage device 13 as appropriate based on the information from the input device @11. Control processing related to design procedure support is executed based on the information regarding the design procedure obtained. Further, the control device 15 includes a search means for searching for one or more lowest layer parameters located at the lowest layer among a plurality of parameters necessary for determining the value of a specific parameter, and a search means for searching for one or more lowest layer parameters located at the lowest layer, a parameter changing means for changing and setting the value of the specific parameter by changing the value of the parameter; and when the parameter affected by changing the value of the specific parameter is a parameter that is not desired to be changed; It has a built-in information setting means for setting information for fixing the value of the parameter in the corresponding frame.

Here, to explain the lowest layer parameters, since the name parameters form a hierarchical structure that is related to each other,
The value of each parameter is determined by the parameter in question, a parameter located in the F layer Barameh・
In addition to all the other parameters necessary to determine the value of a specific parameter, it is not limited to the parameters for determining the value of the frame. Parameters in a frame with no parameters, or parameters required to calculate the value of the parameter, are used to calculate la 2, or parameters for which the value of the parameter is forcibly entered from the input device, ignoring the formula in the frame. This is called the lowest layer parameter.

The display device 17 is connected to the control device 15 and displays information from the control device 15, such as information or parameters related to design procedure support.

Next, an example of a frame in which mutually related information is arranged in a hierarchical structure as information regarding a design procedure stored in the storage device 13 will be described with reference to FIG. 3.

As shown in FIG. 3, the frame includes heading information DS1 indicating the frame name etc. and knowledge information DS corresponding to this heading information.
It is composed of 2. Specifically, the heading information DSI indicates "rFA frame". In addition, the knowledge information DS2 includes output parameters (outpuB), input parameters (input), formula information (siki), fixed information (fixed), and relation information (relati).
on). The output parameter (output) in the knowledge information DS2 indicates the output value for the heading information DS1, but in the example shown in FIG. This indicates that it is necessary to calculate the relational expression included in the expression information (5iki) if the value is required. Note that the process of evaluating something described in a mathematical formula in this way is called starting a daemon.

In addition, input parameters (inpu
t) describes the value of the parameter of this frame, that is, the parameter whose numerical value needs to be input from the output parameter of another frame when calculating the output parameter, and this manual parameter is FB,
b J, rc, cJ are shown. B and C are the names of parameters, and b and C are variables used in the formula. In addition, equation (5iki) includes the equation (b +
c) is shown.

Other frames similarly related to each of the above-mentioned human parameters are set, and information for each frame arranged in a hierarchical structure that is related to each other is stored in the storage device 13.
is stored in.

Therefore, each value of the input parameters shown in FIG.
output parameters) can be determined by reading other relevant frames with the υJla device. In other words, the value of an input parameter required to obtain a certain parameter is obtained by reading the output parameter of the frame that uses the input parameter as header information, and when the output parameter is unknown, the value of the unknown output parameter is It is determined by reading out the output parameters of the frame which have the input parameters necessary for determining the parameters of the frame as header information.

Furthermore, when the output parameter is unknown, it can be found by repeating the above reading.

Further, the input parameters shown in FIG. 3 can be directly input by key operations from the input device 11. In other words, as shown in Figure 3, the relation information (retation) is
n'', the output parameters, which are predetermined design information shown in the heading information, are determined using each of the input parameters and the formula information (5iki) described above. Further, when the relationship information (relation) is f'oHJ, it indicates that the predetermined output parameter is input directly by key operation from the input device 11 without using the above-mentioned formula information (siki).

Also, fixed information (fixed) in knowledge information DS2
is information indicating whether or not to fix the output parameter (output) A, and if the fixed information (fixed) is "ofrJ", other related parameters, such as parameters PB and PC included in the input parameters, are The value of the output parameter A changes according to the value of each variable S, c of the above.On the contrary, when the fixed information (fixed) is "On", each variable S of the related parameters PB, PC, Even if c changes, the value of the output parameter Δ is fixed.

FIG. 4 shows a hierarchical structure of parameters between mutually related frames. The parameter PA shown in Fig. 4 is the third
Parameter A shown in the figure is shown, parameter PB is an input parameter shown in FIG. 3 and shows parameter B of another frame, and parameter PC is an input parameter shown in FIG. 3 and shows a parameter of another frame. Further, parameters PD and PE are input parameters for determining the value of parameter B, and are parameters of other frames. The respective parameters arranged in relation to such a hierarchical structure are sequentially determined according to the respective hierarchical order. For example, parameter PD is determined by parameter PG and parameter PH, and parameter PB is determined by parameter PD and parameter PE. Furthermore, the parameter PA
is determined by parameter PB and parameter PC.

Next, the basic operation of the control device will be explained with reference to FIG.

In step 30, it is determined what to process, and when search information regarding frame i is input using the input device 11 in order to obtain design information of frame l, step 31
Then, based on the search information from the input device 11, the frame i stored in the storage i 13 is searched.

Next, in step 33, it is determined whether an output parameter <output) exists as an output value in the searched frame i, and if an output parameter exists, the process proceeds to step 45, which is the output parameter of this frame i. The information of frame i is answered by outputting a signal that displays the output value on the display device 17. If the output parameter does not exist in frame i in step 33, the process proceeds to step 35, and it is determined from the related information of frame i whether or not this output parameter should be input by the user. That is, in step 35, it is determined whether the relation information < relation) is rOFFJ, and if the relation information (relation) is rOFFJ, the process proceeds to step 37, and the user, that is, the user, needs to input information. A message to that effect is output to the display device 17. This allows the user to input device 1
1 to input predetermined information, the process proceeds from step 37 to step 45, where the information inputted by the input device 11 is displayed on the display device 17 as an output value for the frame.
Outputs a signal indicating that it will be displayed.

If the user should not input the information in step 35, or if the relationship information is set to rONJ, the process advances to step 39, where the value of frame X (output parameter ) to acquire knowledge. That is, in the example shown in FIG. 3, the value (output parameter) of a frame whose heading information is input parameter (input) B and the value (output parameter) of a frame whose heading information is input parameter (input) C are stored in the storage device 13. Read from.

At this time, if the relation information (relation) is rOFFJ, it is set to rONJ. In step 41, it is determined whether all frame X values corresponding to the frame input parameters have been obtained. If all frame X values have been obtained, the process proceeds to step 43, where a so-called daemon is activated. . Taking FIG. 3 as an example, the values of the input parameters B and C obtained from the frame . This calculated output parameter of frame i is
5, a signal to be displayed on the display device 17 as an output value is output. (For details, see Japanese Patent Application No. 61-145657) When fixing information indicating that the value of a specific parameter is to be fixed is input from the input device 11 in step 30, the process proceeds to step 47, where the value of the parameter is fixed. Execute the fixation process for

The process proceeds from step 47 to step 81 to step 51 in FIG.

Next, the operation related to the fixing process of specific parameters is explained in the sixth section.
This will be explained with reference to the figures.

In step 51, a list of parameters included in each frame related to procedural knowledge is displayed on the display device 17. Subsequently, in step 53, a parameter whose value is to be fixed (hereinafter referred to as fixed parameter) is selected from among the plurality of displayed parameters. In step 55, fixed information (fixed information) of the frame including the selected parameter is set.
) to [onJ.

Referring again to FIG. 5, when information indicating that the value of a particular parameter is to be changed or set is inputted from the input device 11 in step 30, the process proceeds to step 57 and processing related to the change or setting of the parameter is started. The process proceeds from step 57 to step 61 in FIG. 7 via step 82.

Next, control processing regarding changing settings of specific parameters included in a frame will be explained with reference to FIGS. 7, 8, and 9.

In step 61, the input GI position 11 is operated to specify the parameter to be changed. Subsequently, in step 63, the display device 17 displays a question asking whether to perform forced input, that is, whether to directly input the value of the parameter to be changed from the input device 11. In step 63, if the input device u outputs an answer indicating that no forced input is to be performed, the process advances to step 65, and among all the parameters necessary to determine the parameter to be changed, the lowest layer parameter located at the lowest layer is selected. Execute search processing.

Here, the lowest layer parameter is a parameter that does not have an input parameter among all the parameters necessary to determine a constant parameter value in step 61, or a parameter that is forcibly input from the input device 11 by ignoring the calculation formula. Refers to the input parameters.

For example, if the parameter PB shown in FIG. 4 is the specified parameter, at least the parameter PG,
PH and PI are the lowest layer parameters.

Next, the search process for the lowest layer parameters in step 65 will be explained in detail with reference to FIG.

In step 101, a variable list LS is created whose elements are parameters that serve as criteria for searching for the lowest layer parameters.

That is, all parameters necessary to determine the value of a specific parameter to be changed are made into elements of the variable list LS. Next, in step 103, variable lists LM and LL are created.
Set an empty list, that is, a blank space, for each. Next, in step 105, the variables are listed and the input parameter of the parameter located at the beginning of S is determined. Step 107
Then, it is determined whether an input parameter exists and the relationship information (relation) corresponding to this input parameter is rONJ. In step 107, if the input parameter exists and the relationship information (relation> is rONJ), the process proceeds to step 109.In step 109, the corresponding input parameter is added to the variable list LL.
Add it to the end of the variable list LS so that it does not overlap with the elements in . Subsequently, in step 111, the corresponding input parameters are added to the variable list LL so as not to overlap with elements of the already existing list LL. Subsequently, in step 113, as the input parameters were added to the end of the variable list LS in step 109 described above, this variable list L
Delete the input parameter located at the beginning of S.

In step 107, if the input parameter does not exist, or even if the input parameter exists, the relation information (relation) corresponding to this input parameter is t'0FFJ, the process proceeds from step 107 to step 115. In step 115, the corresponding parameter, that is, the parameter located at the head of the variable list LS, is added to the variable list LM. Subsequently, in step 117, the parameter located at the head of the variable list LS is deleted.

In step 119, it is determined whether processing has been completed for all parameters existing in the variable list LS, and if processing has not been completed for all parameters, the process returns to step 105 again and the same process as described above is performed. Parameters existing in variable list LS are added to variable list LM
Or sort it to variable list LL. Therefore, the names of all the parameters necessary to determine the value of the specific parameter to be changed are assigned to the variable list LL, and the names of all the parameters necessary to determine the value of the specific parameter to be changed are distributed to the variable list IM. Among the plurality of parameters, the lowest layer parameter located at the lowest layer is distributed. If a parameter value is forcibly entered ignoring the calculation formula or relational formula, even if this input parameter is not located at the lowest layer, it will be assigned a distribution number in the variable list LM as the lowest layer parameter. It will be done.

Referring again to FIG. 7, in step 67, the lowest layer parameter to be changed is selected from among the plurality of lowest layer parameters searched. Subsequently, in step 69, a search is performed for parameters influenced by the selected lowest layer parameter. Parameters that are influenced by specific parameters in this way are referred to as influence parameters. Next, the search process in step 69 will be explained in detail with reference to FIG. 9.

In step 121, a variable list MS of influencing parameters affected by the selected lowest layer parameter, that is, parameters to be searched for, is created. Step 1
In step 23, an empty list, that is, a blank area is set in each of the variable list MM and the variable list ML. Step 12
In step 5, the value of the input parameter located at the beginning of the variable list MS is calculated. Next, in step 127, it is determined whether the above-mentioned input parameter exists and the relation information (relation) corresponding to this input parameter is rONJ. In step 127, if an input parameter exists and the relation information (relation) corresponding to this input parameter is rONJ, the process advances to step 129. In step 129, the corresponding parameter is added to the end of the variable list MS so as not to overlap the elements of the variable list ML. Subsequently, in step 131, the corresponding parameter is added to the variable list ML so as not to overlap with elements already existing in the variable list ML. Subsequently, in step 133, the input parameter located at the beginning of the variable list MS is deleted.

In step 127, if the input parameter does not exist, or even if the input parameter exists, the relation information (relatlOn) corresponding to this input parameter
If is rOFFJ, the process advances from step 127 to step 135. In step 135, the corresponding input parameter, that is, the parameter located at the head of the variable list MS, is added to the variable list MM. Then step 137
Now, delete the input parameters placed at the top of the variable list MS. In step 139, it is determined whether the search process has been completed for all parameters existing in the variable list MS. If the search process for all parameters has not been completed, the process returns from step 139 to step 125 as described above. In the same way as above, the input parameters existing in the variable list MS are distributed and processed. That is, all the influencing parameters affected by the parameter selected in step 67 are included in the variable list ML.
At the same time, among the parameters distributed to these variable lists ML, that is, parameters arranged in a mutually related hierarchical structure, the highest layer parameter existing at the highest layer position is distributed to the variable list MM. At this time, among a plurality of parameters arranged in a hierarchical structure related to each other, even if the parameter is not located at the top layer, the corresponding calculation formula or relational formula is ignored and the parameter is forcibly input from the device 11. is distributed to the variable list MM as the top layer parameter.

Referring again to FIG. 7, the process proceeds from step 69 to step 91 in FIG. 10 via S4. In the control flow shown in FIG. 10, processing is performed depending on whether a fixed parameter exists among the searched parameters in step 69.

Next, the control processing will be explained in detail with reference to FIG.

In step 91, it is determined whether or not a fixed parameter exists among the influence parameters obtained through the search. If there is no fixed parameter, the process proceeds to step 71 in FIG. 7 via S5. If a fixed parameter exists in step 91, the process advances to step 92, and the name and value of the fixed parameter are displayed. Subsequently, in step 93, it is determined whether or not to continue the process related to the design procedure with the displayed fixed parameter values fixed as they are. If the process is to be continued in this state, the process proceeds to step 71 in FIG. 7 via steps 93 to 85. Further, in step 93, if the value of an arbitrary parameter is further changed and the processing related to the design procedure is to be continued, the process advances to step 94. In step 94, it is determined whether forced input is selected, that is, whether the relation information (relation) of the corresponding frame is [ofjJ, and if the relation information (relation> is "oHJ"), S2 is The process then proceeds to step 61 in FIG.

Further, in step 94, relation information (relation
) is "onJF", the process advances to step 96 and it is determined whether or not to reselect the lowest layer parameters.

If the lowest layer parameters are not to be reselected in step 96, the process returns to step 61 in FIG. Return to step 67.

Referring again to FIG. 7, in step 71, a specific parameter to be changed, that is, the selected lowest layer parameter and an influence parameter affected by this specific parameter is stored, and the values before these changes are stored. Store it in the storage device as the old value.

Subsequently, in step 73, the value of the lowest layer parameter selected in step 67 is reset. At this time, if the parameter value is forcibly input, the input device 11 is used to set the parameter value. Subsequently, in step 75, as the parameter values have been reset in step 73, the values of all influencing parameters affected by this parameter reset are set to an undetermined state.

In step 77, the uppermost layer parameter located at the uppermost layer among the influence parameters influenced by the aforementioned lowermost layer parameter is driven. That is, the value of the top layer parameter is changed and set. Further, in step 67, all the values of the influence parameters that are influenced by the selected lowest layer parameter are calculated, and the calculated values are set as new values in each corresponding frame.

In step 79, the old value set in step 71 and the new value set in step 77 are displayed on the display device 17 in the form of comparison clothes so that they can be compared with each other. In step 81, the new value and the old value are displayed, and the user selects one of the values using the input bag W111. If a new value is selected in step 81, the process proceeds from step 81 to step 83.

In step 83, if the value of the input parameter is forcibly input from the input device 11, the relation information (relatoin) existing in the frame of the parameter to be changed is r
Set to OFFJ.

The process then proceeds to step 99 in FIG. 11 via steps 83 to 87. As shown in step 99, if there is a fixed parameter among the parameters affected by the lowest layer parameter, that is, among the influencing parameters,
Fixed information of the frame that includes the fixed parameter (
fixed ) to [oHJ. Next step 9
The process proceeds from step 9 to step 88 in FIG. 7 to step 85.

Subsequently, in step 85, the old values of the relevant parameters are deleted.

In step 63, input parameter values are input to input device 1.
If input is made directly using Step 1, the process proceeds from Step 3 to Step 87. In step 87, the search process shown in FIG. 9 is executed. In other words, if the parameter value is strong 1bl
When input manually, a search for an influence parameter that is affected by this forcibly input parameter is executed.

Steps 87 to 84 to step 91 of FIG.
The program then proceeds to execute the control processing described above.

Next, if the old value is selected in step 81, the process advances from step 81 to step 89.

In step 89, since the old value has been selected, the value of the corresponding parameter is returned to the old value, that is, the value before being changed. In addition, as the value of the above-mentioned parameter, the input device 1
1, the relationship information (rflilation) included in the corresponding frame is input as rOF.
Set from FJ to rONJ.

As described above, since the old value and the new value are compared and displayed on the display device 17, the user can easily select which value to adopt.

Additionally, the four setup procedures can be supported in any order, providing greater flexibility and improving efficiency.

[Effects of the Invention] As described above, according to the present invention, information indicating that the value of any parameter among a plurality of parameters is to be fixed is set in the corresponding frame.
