BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

A system that uses complex physical phenomena, for example, has multiple events that are the factors that lead to an event such as the final quality of a product. In general, many events are linked in a chain such that there are multiple events, and there are multiple events that cause the event as a result. Moreover, in such a complex system, there are many qualities that must be satisfied, so the causal relationship between factors and results becomes extremely complicated. Therefore, it is difficult to find the design items (factors) to satisfy the desired quality (result), and a change in the design value to satisfy a certain quality may adversely affect other qualities. Cheap.
One of the diagrams used to visualize and organize such complex causal relationships is an association diagram. A relational diagram expresses a causal relation by connecting a result and its factors with a relational line, and a logic tree is a typical example thereof. Linkage diagrams are suitable for showing results and their causes in detail without omission or duplication.

By the way, when estimating the causal relationship between events by classifying the events into their results and their factors from the data, an unintended causal relationship may occur depending on the subject setting. If the causal relationship between events is known in advance, it is effective to estimate the causal relationship using data while fixing the causal relationship. However, in a system that uses complex physical phenomena, many events are often linked in a chained and intersecting manner, making it difficult to extract causal relationships without omission.

Therefore, in the present embodiment, the direction of the causal relationship between events is defined in the association diagram created by the user's operation, and the causal relationship between data is estimated while the defined causal relationship is fixed.

FIG. 8 is an explanatory diagram of an example of a technique (mechanism of a straw whistle) targeted for a relational diagram and a development table.
Bernoulli's theorem (see Equation 1), which is a fluid engineering law that "pressure decreases as the flow velocity increases" is used.

"Why it vibrates" can be explained as follows. The numbers in parentheses correspond to the numbers in parentheses in FIG.
(1) As the flow speed increases, the flow speed in the straw increases (2) As the flow speed increases, the pressure decreases (3) As the pressure decreases, the reeds are drawn in (4) As the reeds are drawn in, the flow path narrows ( 5) When the flow path narrows, the flow rate slows down. (6) When the flow rate slows down, the pressure returns to the original state. (7) When the pressure returns, the reed opens. Return to (1).

In the example of FIG. 9, each item surrounded by a rectangle is connected by relational lines. An upward arrow within an item indicates that the item has increased, and a downward arrow indicates that the item has decreased.
The color of the relationship line between items indicates the polarity of the causal relationship. A solid relational line connecting items indicates that there is a positive correlation, and a dashed relational line connecting items indicates that there is a negative correlation. For example, when the item "ease of vibration" decreases, the item "ease of sound output" also decreases. Also, the degree of influence of the causal relationship may be indicated by thick and thin lines. These pieces of information are stored in the attribute column 1120 of the relationship line information table 1100. FIG.

First, the process of associating data elements with items in the association diagram will be described.
FIG. 13 is an explanatory diagram showing an example of the screen.
In the selection area 301, the item "pressure difference during opening" is selected as an analysis target in the association diagram.
In the operation area 302, the data elements linked in association with the items of the relationship diagram are displayed as the analysis targets in the actual data corresponding to the relationship diagram, and the data elements are linked to the items of the relationship diagram. It is provided so as to function also as an area for
A display area 303 displays a plurality of items in the association diagram.
A display area 304 displays a plurality of data elements read from a set of data acquired as actual system operation data and article measurement data.
In this state, the user selects a data element out of the plurality of data elements displayed in the display area 304 and selects an item in the operation area 302 corresponding to the certain item out of the plurality of items displayed in the display area 303 . position (for example, a line in the same operation area 302 as a certain item). Then, the data element selected from among the plurality of data elements is linked to the item displayed at the position corresponding to the drag destination position within the operation area 302, among the plurality of items displayed in the display area 303. be done. For example, the data element “O_PRESSURE” is linked to the item “pressure difference during opening” by being dragged to the hatched portion of the operation area 302 . In addition, among the plurality of data elements displayed in the display area 304, a data element already associated with one of the items displayed in the display area 303 is marked with a mark to that effect.

FIG. 14-1 is a flow chart showing an example of processing according to this embodiment.
In the information processing apparatus 100, first, the analysis information processing module 165 receives designation of an analysis target (step 601). In the screen example of FIG. 13, the item ID of the item selected in the selection area 301 is accepted.
Next, the analysis information processing module 165 determines whether or not the user has performed a linking operation to link a certain data element to a certain item (step 602). If it is determined that the user has performed the linking operation, the analysis information processing module 165 accepts the linking operation (step 603). In the screen example of FIG. 13, among the plurality of data elements displayed in the display area 304, the data element ID of the data element dragged to the operation area 302 and the data element ID of the plurality of items displayed in the display area 303 The item ID of the item displayed at the position corresponding to the position in operation area 302 where the element was dragged is received. For example, the data element ID of the data element "L_HARDNESS" is accepted as the data element ID of the data element dragged to the operation area 302, and the item displayed at the position corresponding to the position within the operation area 302 where the data element was dragged. The item ID of the item "hardness of lead" is accepted as the item ID of the item.
As a result, the analysis information processing module 165 reads out the item information table 1000 for the item that is the target of the linking operation received in step 603 from the association diagram storage module 145, and stores in the data element ID column 1040 in step 603 The data element ID of the data element that is the target of the received linking operation is set (step 604). For example, the data element ID "0009" of the data element "O_PRESSURE" subject to the linking operation is set for the item "pressure difference during opening" received in step 603. FIG.
In addition, the analysis information processing module 165 reads the element analysis information table 1200 for the data element that is the target of the linking operation received in step 603 from the analysis information storage module 150, and stores in the item ID column 1215 in step 602 The item ID of the item that is the target of the received linking operation is set, and the data element ID of the data element that is the target of analysis received in step 601 is set in the analysis target column 1220 (step 605).
At this time, the flow of setting data in the element analysis information table 1200 will be specifically described with reference to FIGS. 14-2 and 14-3. Dataset table 1400 shown in FIG. 14-2 shows the data format of the set of data elements displayed in display area 304 of FIG. Data elements "A_DENSITY", "A_FLOW", . . . are assigned data element IDs "0001", "0002", . Further, the data element linked to the item in step 603 is marked with a circle indicating that it has been designated as an analysis target. In step 605 above, the element analysis information table 1200 for the data element "O_PRESSURE" linked to the item "pressure difference during opening" selected as the item to be analyzed is read, and the data set table 1400 is referenced. By doing so, "O_PRESSURE" is set to the data element name, "0009" is set to the data element ID, and the item ID "1234" given to the linked item "pressure difference during opening" is set. . Further, as the data elements to be analyzed, the data set table 1400 is referred to, and the IDs of the data elements marked with "o" are set to "0002", "0005", "0006", . . . In the element analysis information table 1500 shown in FIG. 14-3, a data element ID 1505, a data element name 1510, an item ID 1515, and an analysis target 1520 are set. Since no analysis processing is performed here, the importance level 1525 is not set.
After that, the analysis information processing module 165 returns the process to step 602, and ends the process unless it determines that the user has performed the linking operation.

Next, a description will be given of processing when a relationship line between items is specified and analysis of the relationship between data elements is instructed.
FIG. 15 is an explanatory diagram showing an example of processing for an association diagram according to this embodiment.
In FIG. 15, it is assumed that the linking operation shown in FIG. 13 has been performed.
In this state, a relationship line between certain items is specified as a fixed relationship line. In FIG. 15, a relational line 401 between the item "hardness of lead material" and the item "modulus of elasticity" is specified as a fixed relational line (indicated by a thick line).

FIG. 16 is a flowchart showing an example of processing according to this embodiment.
In the information processing apparatus 100, the relationship fixation module 180 first receives an instruction to analyze the relationship between data elements specifying the relationship line between items in the association diagram (step 621).
As a result, the relationship fixing module 180 reads out the relationship line information table 1100 for the relationship line specified in step 621 (step 622).
Next, the relationship fixing module 180 retrieves the connection source item ID set in the connection source item ID column 1110, the connection destination item ID set in the connection destination item ID column 1115, and the attribute column 1120 from the relationship line information table 1100. The direction of the set attributes is obtained (step 623).
Next, the relationship fixing module 180 acquires the data element ID set in the data element ID column 1040 from the item information table 1000 corresponding to the connection source item ID acquired in step 623, and obtains the connection destination acquired in step 623. The data element ID set in the data element ID column 1040 is obtained from the item information table 1000 corresponding to the item ID (step 624).
Then, the analysis module 175 analyzes the relationship between the data elements while fixing the direction of the relationship between the two data elements acquired in step 624 to the direction acquired in step 623, and creates the relationship analysis information table 1300. store the result in (step 625). For example, the relationship analysis information table 1300 is generated for each pair consisting of two data elements, the pair ID of the pair consisting of the two data elements is set in the pair ID column 1305, and the first data element ID column 1310 is set. , the data element ID of the first data element of the two data elements is set, and the data element ID of the second data element of the two data elements is set in the second data element ID column 1315. and sets the degree of relevance between the two data elements in the degree of relevance column 1320 thereof.

Next, the process of outputting the result of data element relationship analysis on the association diagram will be described.
FIG. 17 is an explanatory diagram showing an example of processing for an association diagram according to this embodiment.
FIG. 17 also assumes that the linking operation shown in FIG. 13 has been performed. Also, as shown in FIG. 15, it is assumed that a relationship line between certain items is designated as a fixed relationship line.
For example, it is assumed that the relational line 401 from the item "modulus of elasticity" to the item "hardness of lead material" is designated as the fixed relational line.
In this state, the relationship between data elements is analyzed with the relationship lines fixed, and the display elements showing the results are displayed.
For example, a display element representing a data element may be a bubble-shaped figure (bubble object), and a display element representing a directional relationship between an item and a data element may be an arrow-shaped figure (arrow object). . In FIG. 17, an arrow object 411 is displayed from the bubble object 421 representing the data element "S_MATERIAL" to the item "modulus of elasticity" to which the data element "L_ELASTICITY" is linked. An arrow object 412 is displayed for the item “hardness of lead material” linked to the element “L_MATERIAL”.

In this example, if the item "modulus of elasticity" is an example of a specific item, the data element "L_ELASTICITY" is an example of first data associated with the specific item. If the item "hardness of lead material" is an example of a specific item, the data element "L_MATERIAL" is an example of first data associated with the specific item. Also, if the data element "S_MATERIAL" is an example of second data that is not associated with any item, the arrow object 411 is a display element indicating second data that is associated with the first data or a second data that is associated with the first data. It is an example of a display element showing the directionality between the first data and the second data. Given that data element "S_THICKNESS" is an example of second data that is not associated with any item, arrow object 412 is a display element that indicates second data that is associated with the first data or the first data item. It is an example of a display element showing directionality between data and second data. Furthermore, here, the arrow object is displayed in combination with the item and the data element, but the present invention is not limited to this. Arrow objects may be displayed in association with items and data elements.

Alternatively, an arrow object may be displayed between items to which data elements are linked. For example, an arrow object may be displayed between the item "modulus of elasticity" associated with the data element "L_ELASTICITY" and the item "diameter" associated with the data element "S_DIAMETER".

Note that in this example, the item "modulus of elasticity" is an example of a first item, and the data element "L_ELASTICITY" is an example of first data associated with the first item. Also, the item "diameter" is an example of a second item, the data element "S_DIAMETER" is an example of second data associated with the second item, and the items "modulus of elasticity" and the item "diameter" The arrow object between is an example of a display element indicating the second data related to the first data or a display element indicating the directionality between the first data and the second data.

FIG. 18 is a flowchart showing an example of processing according to this embodiment. In FIG. 17, only one of the two data elements whose relationship is analyzed by the inter-data element relationship analysis is associated with the item. It is explained as if there is
In the information processing apparatus 100, first, the analysis information processing module 165 receives an instruction to display the result of the relationship analysis between data elements (step 641).
As a result, the analysis information processing module 165 reads out the relationship analysis information table 1300 for a pair of two data elements from the analysis information storage module 150 (step 642). For example, one pair ID is selected in the order of pair IDs, and the relationship analysis information table 1300 corresponding to the pair ID is read.
Next, the analysis information processing module 165 reads the element analysis information table 1200 and the second element analysis information table 1200 for the first data element based on the first data element ID and the second data element ID set in the relationship analysis information table 1300 read in step 642 . The element analysis information table 1200 for the data element is read, and it is determined whether an item ID is set in the item ID column 1215 of both element analysis information tables 1200 (step 643). If it is determined that the item ID is set in the item ID column 1215 of both element analysis information tables 1200, it means that both the first data element and the second data element are associated with the item. The information processing module 165 reads two item information tables 1000 for these two item IDs (step 644).
Next, the analysis information processing module 165 sets the two item IDs determined to be set in the two element analysis information tables 1200 in step 643 to the connection source item ID column 1110 and the connection destination item ID column 1115. It is determined whether or not there is a relationship line information table 1100 (step 645). If it is not determined that there is such a relational line information table 1100, the output module 170, in step 644, displays the display element with a thickness corresponding to the degree of relevance set in the degree of relevance column 1320 of the relational analysis information table 1300. The two coordinates respectively set in the coordinate columns 1015 of the two item information tables 1000 read out are displayed so as to connect them (step 646). Here, "to display so as to connect the coordinates" means to display so as to connect the positions associated with the coordinates. In other words, it is not required to display so that both ends of the display element exactly match the coordinates.

On the other hand, if it is not determined in step 643 that the item ID is set in the item ID column 1215 of both element analysis information tables 1200, at least one of the first data element and the second data element is associated with the item. Therefore, if there is an item associated with one of the first data element and the second data element, the analysis information processing module 165 reads the item information table 1000 for that item (step 647). Then, the output module 170 sets the display element with the thickness corresponding to the degree of association set in the degree of association column 1320 of the relationship analysis information table 1300 to the coordinate column 1015 of the item information table 1000 read in step 647. Display is performed so as to connect the coordinates with arbitrary coordinates at which the display element representing the data element determined not to be linked to the item in step 643 is displayed (step 648). Here, "to display so as to connect the coordinates" means to display so as to connect the positions associated with the coordinates. In other words, it does not require display so that both ends of the display element exactly match the coordinates. good.
Note that the relationship line information table 1100 in which the two item IDs determined to be set in the two element analysis information tables 1200 in step 645 are set in the connection source item ID column 1110 and the connection destination item ID column 1115 is If so, the output module 170 advances the process to step 649 without displaying the display element because the relationship line is already displayed between the items of these two item IDs.
After that, the analysis information processing module 165 determines whether or not there is another relationship analysis information table 1300 that has not been read (step 649). If the analysis information processing module 165 determines that there is another relationship analysis information table 1300 that has not been read, it returns the process to step 642. If it determines that there is another relationship analysis information table 1300 that has not been read, the process exit.
