Description

  The present invention relates to a discussion support apparatus and a discussion support method.

  The technology that structures and visualizes the relationships between various events that occur in society is called system dynamics. As a method for expressing the structure between events in system dynamics, a CLD (Causal Loop Diagram) having “nodes” indicating events and “links” indicating causal relationships between the nodes is used. By using CLD, express the correlation and problems of structured events, and discover structural points that lead to continuous improvement of the problems (hereinafter also referred to as “resolved points”) You can be ready.

  In the CLD created by the causal relationship diagram generation support system of Patent Document 1, each node has a time-series numerical value (FIG. 4 of Patent Document 1). Each link has a “time delay” value and a positive or negative sign (FIG. 12 of Patent Document 1). A positive sign indicates that there is a positive correlation between the time series values of the two nodes to which the link is connected. A negative sign indicates that there is a negative correlation between the time series values of the two nodes to which the link connects. The value of the time delay being “1”, for example, indicates that the change in the cause node is delayed by “1 period” and is synchronized with the change in the resulting node. When the causal relationship diagram generation support system of Patent Document 1 is used, the user of the system can not only understand the relationship between nodes statically, but also dynamically understand the relationship between nodes by incorporating the concept of time. be able to. Thus, the possibility of finding a solution point from a medium to long-term perspective is increased.

However, in order for the user of the causal relationship diagram generation support system disclosed in Patent Document 1 to find a solution-required part while looking at the CLD, considerable experience is required. Furthermore, even when experienced users discuss with each other, it is rare that a point requiring a solution can be found on the spot. In most cases, the user repeatedly interrupts and resumes the discussion, and finally finds a solution point. In other words, if the progress of the discussion is not displayed effectively, a so-called dignity occurs and the quality and speed of the discussion deteriorate. The causal relationship diagram generation support system of Patent Document 1 is not particularly aimed at easy discovery of a required solution point and display of the progress of discussion, and a separate measure is required to solve these problems.

The present embodiment is an example in which the CLD is used to find a solution-necessary portion (location that needs to be solved) hidden in an environmental problem, but the present invention can also be applied to other examples.

(Terms etc.)
An event is a social or natural phenomenon that can be expressed as a statistical value that changes over time. For example, the event “number of eco products / services” can be expressed in time series as the number of types of products or services aimed at saving resources. The event “eco product / service ratio” can be expressed in time series as a ratio of the number of types of products or services for the purpose of resource saving out of the total number of types of products or services distributed in the market. In the following description of the CLD, an event may be simply expressed as “event A”.

A cause is a temporal or logical preceding of two events. A result is a temporal or logical succession of two events. For example, as the statistical value of the event “eco product / service number” increases in time series, the statistical value of the event “eco product / service ratio” also increases. At this time, the former is the cause and the latter is the result.
A causal relationship is a relationship between one preceding cause and one following result.
Correlation is the relationship between the change in the statistical value of the causal event and the change in the statistical value of the resulting event. A positive or negative correlation coefficient is defined between the two statistics (detailed later).

  Delay is the time (non-negative real number) until the time series change of the statistical value of the event that occurs after the time series change of the statistical value of the cause event occurs, that is, until the correlation appears It's time. For example, a change in the statistical value of the event “eco product / service number” immediately changes the event “eco product / service ratio”. Therefore, the delay between the event “number of eco products / services” and the event “eco product / service ratio” is “0”. Another example is the event “environmental literacy” statistics (number of laws related to environmental protection, etc.) after an increase in a certain year, then the event “environment native” statistics (population learned in textbooks dealing with environmental protection, etc.) ) Increases, for example, it takes one year. In this case, the delay between the event “environment literacy” and “environment native” is “one year”.

(Mathematical meaning of delay and correlation coefficient)
In general, let x and y be two statistical values that change in time series. Statistics of the n-th period of x as x _n, the statistical value of y of the n phase and y _n. However, n = 1, 2, 3,... Paying attention to changes in the time series of x and y, let Δx _n = x _{n + 1} −x _n and Δy _n = y _{n + 1} −y _n .

Thereafter, the discussion support apparatus of the present embodiment first checks the correlation between Δx _n and Δy _n . That is, regarding the change in the statistical value between the same periods such as (Δx ₁ , Δy ₁ ), (Δx ₂ , Δy ₂ ), (Δx ₃ , Δy ₃ ), (Δx ₄ , Δy ₄ ),. Examine the correlation. Next, in the same manner, the correlation between Δx _n and Δy _{n + 1} is examined. In other words, regarding changes in statistical values shifted by one period such as (Δx ₁ , Δy ₂ ), (Δx ₂ , Δy ₃ ), (Δx ₃ , Δy ₄ ), (Δx ₄ , Δy ₅ ),. Examine the correlation. Further, similarly, the correlation between Δx _n and Δy _{n + 2} is examined. That is, the change in statistical values shifted by two periods such as (Δx ₁ , Δy ₃ ), (Δx ₂ , Δy ₄ ), (Δx ₃ , Δy ₅ ), (Δx ₄ , Δy ₆ ),. Examine the correlation.

When these are generalized, the discussion support apparatus eventually checks the correlation between Δx _n and Δy _{n + i} . That is, the correlation of statistical values shifted in the i period such as (Δx ₁ , Δy _{1 + i} ), (Δx ₂ , Δy _{2 + i} ), (Δx ₃ , Δy _{3 + i} ), (Δx ₄ , Δy _{4 + i} ),. It will be. However, i = 0, 1, 2,...

The discussion support apparatus obtains i that maximizes the correlation coefficient r (Δx _n , Δy _{n + i} ), that is, r is closest to “1” (where r> 0). Then, x and y have a positive correlation with i phase delay. Similarly, the discussion support apparatus obtains i that minimizes the correlation coefficient r (Δx _n , Δy _{n + i} ), that is, r is closest to “−1” (where r <0). Then, x and y have a negative correlation with i phase delay. In this way, the discussion support apparatus can determine the delay length “i” and the positive / negative correlation at a time for a certain causal relationship.

(Figures on CLD, etc.)
In the CLD of this embodiment, each event is displayed as a “node”. In addition, the causal relationship is displayed as a “link” which is a directed line segment connecting two nodes. A node serving as a link starting point and a node serving as an end point correspond to a cause and a result, respectively. In the following description, “event” is synonymous with “node”, and “causal relationship” is synonymous with “link”.

  If there is a positive correlation between cause and effect, the link between them is called a “positive link”. If there is a negative correlation between cause and effect, the link between them is called a “negative link”. The node “eco product / service number” and the node “eco product / service ratio” are connected by a positive link. As another example, a node “convenient / economic-oriented product / service number” and a node “environment-friendly product / service number” are assumed. The node “convenience / economic importance product / service number” can be expressed in time series as the number of types of products or services for the purpose of improving convenience or economy. The node “number of environmentally conscious products / services” can be expressed in time series as the number of types of products or services intended for environmental protection. Pursuing convenience or economy usually sacrifices environmental protection. Therefore, the node “convenience / economic importance product / service number” and the node “environment-friendly product / service number” are connected by a negative link.

(Direction of statistical value change and its reversal)
As a matter of course, the direction of the change in the statistical value of the first node is reversed when passing through one negative link. Furthermore, after passing through another negative link, the direction once reversed is further reversed, and eventually returns to the direction of change in the statistical value of the first node. A specific example will be described below on the premise that there is a causal chain of “node A → node B → node C”.

(1) It is assumed that there is a positive correlation between the statistical value of node A and the statistical value of node B, and there is also a positive correlation between the statistical value of node B and the statistical value of node C. In this case, when the statistical value of node A increases in time series, the statistical value of node C also increases in time series.
(2) Assume that there is a positive correlation between the statistical value of node A and the statistical value of node B, and there is a negative correlation between the statistical value of node B and the statistical value of node C. In this case, when the statistical value of node A increases in time series, the statistical value of node C decreases in time series.
(3) It is assumed that there is a negative correlation between the statistical value of node A and the statistical value of node B, and there is also a negative correlation between the statistical value of node B and the statistical value of node C. In this case, when the statistical value of node A increases in time series, the statistical value of node C also increases in time series.

  When the nodes connected by the link are traced in order, the node may return to the original node. In this case, a set of a plurality of nodes and a plurality of links connected in a ring shape is called a “loop”. A plurality of loops may share one or a plurality of nodes. Multiple loops may share one or multiple links. When attention is paid to the number of negative links included in one loop and the number of negative links is an even number including “0”, the loop is referred to as a “self-enhanced loop”. If the number of negative links is an odd number, the loop is called a “balanced loop”.

(Interpretation of loop)
For convenience of explanation, FIGS. 1 to 9 are skipped. First, in FIG. 10, attention is paid to the loop R02. The loop R02 has four nodes of “eco product / service ratio”, “event C”, “environment literacy”, and “environment native”. There is a causal relationship between the node “eco product / service ratio” and the node “event C” in which the former is the cause and the latter is the result. There is a causal relationship between the node “event C” and the node “environment literacy” in which the former is a cause while the latter is a result.

  There is a causal relationship between the node “environment literacy” and the node “environment native” in which the former is the cause and the latter is the result. There is a causal relationship between the node “environment native” and the node “eco product / service ratio” in which the former is the cause and the latter is the result. If the links are followed in order, after starting from the node “eco product / service ratio”, the user returns to the node.

  All four links included in the loop R02 are positive links. Therefore, since the number of negative links included in the loop R02 is “0” (even number), the loop R02 is a self-strengthening loop. A link having a delay length equal to or greater than a predetermined threshold is called a “time lag link”. For example, among the four links included in the loop R02, only the link between the node “environment literacy” and the node “environment native” is a “time lag link”. The directed line segment indicating the time lag link is cut by two lines.

  Next, in FIG. 10, attention is paid to the loop R03. The loop R03 has three nodes “event C”, “environment literacy”, and “event D”. Among these, the node “event C” and the node “environment literacy” are shared with the loop R02. The link between the node “event C” and the node “environment literacy” is also shared with the loop R02. There is a causal relationship between the node “environment literacy” and the node “event D” in which the former is the cause while the latter is the result. Between the node “event D” and the node “event C”, there is a causal relationship in which the former is a cause while the latter is a result.

  Of the three links included in the loop R03, only the link between the node “event D” and the node “event C” is a negative link, and the other links are positive links. A directed line segment indicating a positive link is a solid line, whereas a directed line segment indicating a negative link is a broken line. Therefore, since the number of negative links included in the loop R03 is “1” (odd number), the loop R03 is a balanced loop. The loop R03 does not have a time lag link.

  In FIG. 10, finally, attention is paid simultaneously to the loop R02 and the loop R03. The directions of the four links included in the loop R02 (that is, the rotation direction of the loop R02) are counterclockwise. The directions of the three links included in the loop R03 (that is, the rotation direction of the loop R03) are clockwise. Therefore, it is expected that a synergistic effect will occur as if the two gears are engaged. However, simply expecting this synergistic effect is dangerous. The reason is shown below.

  Loop R02 is a self-strengthening loop. Thus, it can be expected that the statistics of each node will be strengthened in the same direction. For example, as the statistical value of the node “event C” increases, the statistical value of the node “environment literacy” also increases. This change is chained to further increase the statistics of node “Event C”.

  The loop R03 is a balance loop. As the statistical value of the node “event C” increases, the statistical value of the node “environment literacy” also increases. As the statistical value of the node “environment literacy” increases, the statistical value of the node “event D” also increases. However, as the statistical value of node “event D” increases, the statistical value of node “event C” decreases. Then, it is unclear whether the statistical value of “event C” will increase or decrease over time. Thus, the change in the balance loop statistic cancels the change in the self-enhancement loop statistic. This is the basis for naming the “balance loop”.

  In other words, the loop R02 and the loop R03 are highly likely to disappear in the near future. Therefore, you should not overestimate the existence of synergistic effects. As countermeasures, (i) eliminate the time group, (ii) make the negative link a positive link, and (iii) add one negative link to the loop R03 to make the loop R03 a self-enhanced loop. , Etc. are conceivable. In addition, as described above, loops are classified as “self-enhanced loops” and “balance loops”, and are classified as “main loops” and “sub-loops” from another viewpoint, and from another viewpoint, “circular loops”. "And" vicious circle loop "(detailed below).

  In step S1, the CLD display unit 21 of the discussion support apparatus 2 displays the CLD screen 51 (FIG. 10). Specifically, the CLD display unit 21 displays the CLD screen 51 on the table type input / output device 3 based on the node information 31 (FIG. 3), the link information 32 (FIG. 4), and the loop information 33 (FIG. 5). To do. On the CLD screen 51, a theme 151, a CLD 152, a description 153, and a point of interest 154 are displayed.

In step S2, the CLD display unit 21 displays the statistical value screen 52 (FIG. 11). Specifically, first, the CLD display unit 21 accepts that the user selects a node by touching the arbitrary node with a finger. Here, it is assumed that the user touches the node “environment native” and the node “environment literacy”.
Secondly, the CLD display unit 21 displays time-series statistical values for the selected node on the screen input / output device 4 as a statistical value screen 52. That is, the “environment native” time series statistics 161 and the “environment literacy” time series statistics 162 are displayed as graphs on the same time axis. The user knows that although there is a positive correlation between the two, there is a delay that cannot be ignored.

Tap the area with your finger.
Second, the discussion support unit 22 displays the memo creation screen 54 on the tablet input / output device 5 of the user who has input the “memo creation request”.

  The user can input a character string in the text input field 201 and input a handwritten image, character string, or the like in the handwriting input field 202. Further, the user can input a memo classification (task, measure, or comment) by touching any one of the classification buttons 203 to 205 with a finger. The discussion support unit 22 receives the input information. Here, the user inputs “more people think that” in the text input field 201, and the handwritten character string “current elementary school 5th grade or higher after learning from the current textbook, Suppose you enter the question "Is it possible to learn environmental problems in junior high school?" Then, it is assumed that the classification button 203 (corresponding to “task”) is touched.

Specifically, first, the discussion support unit 22 displays a memo attachment screen 55 on the table type input / output device 3. The memo attachment screen 55 is different from the CLD screen 51 (FIG. 10) in that the explanation column 153 is omitted and a memo column 206 is added. The discussion support unit 22 displays a memo in the memo field 206 based on the input information received in “second” in step S4. In several notes, "more people think ..." and "If you are in the fifth grade or older, will you learn ..." (handwritten characters are converted into text) are written. A single note is included. It should be noted that the discussion support unit 22 displays the memos in different manners (such as different colors) depending on the memo categories (tasks, measures, or comments).

Second, the discussion support unit 22 touches an arbitrary memo displayed on the memo column 206 by the user (mainly the facilitator 6) with a finger, and immediately after that touches an arbitrary node displayed on the memo attachment screen 55. Accept touch with your finger. Here, the number of people who think that the memo “... is increasing. More than the current fifth graders ... will they learn?” And immediately after that, the node “environment native” was touched. To do.
Thirdly, the discussion support unit 22 creates a new record of the memo information 34 (FIG. 6). Then, the input category (here, “task”) is stored in the category field 133 of the new record, and the number of people who think that the input character string “... Is increasing. ... is it learned? "Is stored in the memo content column 134. Further, the node ID column 132 stores the node ID of the node “environment native”, and the memo ID column 131 stores the memo ID after numbering.

  The discussion support unit 22 repeats the processes of steps S4 and S5 each time the user inputs a “memo creation request”. In the paragraph in which the repetitive processing is completed, the memo information 34 (FIG. 6) stores a record equal to the number of “memo creation requests”.

In step S6, the discussion support unit 22 displays the node list screen with memo 56 (FIG. 15). Specifically, first, the discussion support unit 22 acquires the node ID stored in the node ID column 132 of the memo information 34 (FIG. 6).
Second, the discussion support unit 22 calculates the total score as follows for each node specified by the node ID acquired in “first”.

(1) Referring to the memo information 34, it is determined whether or not the search condition “m1” of the score information 35 (FIG. 7) corresponds to the memo attached to the node. If applicable, a score “5” is given to the node. This process is repeated for all search conditions m2, m3,... For the type “memo”.
(2) Referring to node information 31 (FIG. 3), link information 32 (FIG. 4) and loop information 33 (FIG. 5), it is determined whether or not the search condition “n1” of score information 35 corresponds to the node. To do. If applicable, a score “10” is given to the node. This process is repeated for all search conditions n2, n3,... For the type “node / link”.
(3) The scores given for each node are summed to obtain a total score.

  Third, the discussion support unit 22 rearranges the nodes specified by the node ID acquired in “first” in descending order of the total score. Note that rearranging in descending order is an example, and rearranging in ascending order is also possible. That is, the discussion support unit 22 can arbitrarily rearrange the nodes based on the magnitude relationship of the total score.

Fourth, the discussion support unit 22 displays the node list screen with memo 56 on the table type input / output device 3. On the node list screen with memo 56, one or more memos are displayed in association with the node in the event column 207. When the memo classification is “task”, the memo is displayed in the task column 208. When the memo classification is “measure”, the memo is displayed in the measure column 209. When the memo classification is “comment”, the memo is displayed in the comment field 210.
Fifth, the discussion support unit 22 accepts that a certain user (mainly the facilitator 6) touches an arbitrary memo with a finger on the node list screen 56 with memo. This memo is called an “idea supplement target memo”.

  In step S7, the discussion support unit 22 displays the idea creation screen 57 (FIG. 16). Specifically, first, the discussion support unit 22 displays the idea creation screen 57 on the tablet input / output device 5 of each user (mainly the participant 7). In the idea viewpoint column 211, an idea supplement target memo is displayed.

Secondly, the discussion support unit 22 accepts that the user inputs the following supplementary information (1) to (5).
(1) The user inputs a character string in the title field 212. Here, it is assumed that “TV broadcast for junior high school students” is input.
(2) The user inputs a handwritten image, a character string, and the like in the handwriting input field 213. Here, it is assumed that a handwritten character string “search for a TV broadcast sponsor for junior high school students” is input.

(3) The user inputs a character string into the “who” column 214 and the “how happy” column 215. Here, it is assumed that “learning school manager” and “expect advertising effect on target customers” are entered in the “who” column 214 and the “how happy” column 215, respectively.
(4) The user inputs a character string in the “other notice” column 216. Here, it is assumed that “do not criticize the government” is entered.
(5) The user selects one solution category from the candidates displayed in the solution category field 217. Details of the resolution category will be described later.

  In step S8, the discussion support unit 22 displays the solution category confirmation screen 58 (FIG. 17). Specifically, first, the discussion support unit 22 displays the solution classification confirmation screen 58 on the table type input / output device 3. The vertical axis of the solution category confirmation screen 58 is the “idea supplement target memo” described above. The horizontal axis is the resolution category. The solution category is a specific business mode for solving a required solution point. The user sets a resolution category for each theme. Here, six solution categories such as “demand side—buy and sell” are set. For example, “demand side—buying and selling” collectively indicates that “leading junior high school students who are on the demand side of educational services to buying and selling products provided by the sponsor”.

A plurality of horizontal axes (solution categories) may be stored in the auxiliary storage device 13 (not shown) in association with the node field (field field 105 in FIG. 3). Then, the discussion support unit 22 may change the horizontal axis for each field of the node to which the “idea supplement target memo” is attached. In the cell at the intersection of the vertical axis and the horizontal axis, the image or the like input in the handwriting input field 213 in FIG. 16 is reduced and displayed, and the number of images or the like is displayed. The discussion support unit 22 previously assigns each solution category to each area of the “business model canvas” and stores the corresponding relationship (details will be described later).
Second, the discussion support unit 22 accepts that the user touches an arbitrary “idea supplement target memo” on the vertical axis with a finger.

  In step S9, the discussion support unit 22 displays the idea summary screen 59 (FIG. 18). Specifically, first, the discussion support unit 22 displays the idea summary screen 59 on the table type input / output device 3. A theme is displayed in the theme column 221. In the noted memo field 222, the “idea supplement target memo” touched by the user in “second” in step S8 is displayed. In the theme summary column 223, any material that can be used to obtain a summary of the theme is displayed. In the discussion result column 224, a pattern (required solution location) including a node with “idea supplement target memo” is displayed. In the related data column 225, a time series statistical value of the node and the node causing the node is displayed in a graph format.

In the noticed social change column 226, the point of interest of the main loop included in the pattern (the point of interest column 128 in FIG. 5) is displayed. In the idea sheet column 227, among the idea creation screen 57 (FIG. 16) corresponding to the “idea to be supplemented memo” touched by the user, “title”, “handwritten input”, “who” and “how happy” However, it is displayed in a reduced size with a resolution classification. In the column 228, the “idea supplementary memo” on the vertical axis in FIG. 17 is displayed, and only the items displayed in the “focused memo” column 222 are displayed in a different form. When the user touches the other “idea supplement target memo” with the finger in the field 228, the discussion support unit 22 transitions the idea summary screen 59 to that for another “idea supplement target memo”.
Second, the discussion support unit 22 accepts that the user touches the “business model canvas” field 229 with a finger.

  In step S10, the discussion support unit 22 displays the business model canvas screen 60 (FIG. 19). Specifically, first, the discussion support unit 22 displays the business model canvas screen 60 on the table type input / output device 3. One record (row) in the idea sheet column 231 corresponds to the character string input in the title column 212, the “who is” column 214, the “how happy” column 215, and the “other notice” column 216 in FIG. doing.

Second, the discussion support unit 22 accepts that the user touches the icon 232 of an arbitrary record among a plurality of records in the idea sheet field 231 with a finger. Then, the discussion support unit 22 displays the business model canvas 233. The business model canvas 233 displays an area (immediately described later) to which the record belongs. For example, the first line of the idea sheet column 231 belongs to the area “CH” of the business model canvas 233, and the second line belongs to the area “C $”. Each area presents business considerations.
After displaying the business model canvas 233, the entire processing procedure is terminated.

(Business model canvas)
The “business model canvas” 233 is a known tool used when discussing a new business model. The business model canvas 233 has nine areas named as follows, just like a canvas (art material).

  “Key Partners (KP)” means “key partners” and is a business partner for business entities. “Key Activities (KA)” means “major activities” and is the main economic activity performed by business entities. “Key Resources (KR)” means “management resources” and is an asset necessary for business. “Value Propositions (VP)” means “value proposal” and is a product or service provided by a business entity. “Customer Relationships (CR)” means “customer relationships”. “Channels (CH)” means “channels” and is a sales channel of products or services. “Customer Segments (CS)” means “customer segments” and is a specific customer targeted by a business entity. “Cost Structure (C $)” means “cost structure” and is information that a business entity must create at a cost. “Revenue Streams (RS)” means “revenue flow”.

(Solution point extraction processing procedure)
A solution point extraction process procedure will be described with reference to FIG. The solution point extraction processing procedure is details of step S3 of the overall processing procedure.

  In step S301, the CLD display unit 21 of the discussion support apparatus 2 determines a pattern to be highlighted. Specifically, the CLD display unit 21 refers to the node information 31 (FIG. 3), the link information 32 (FIG. 4), and the loop information 33 (FIG. 5), and extracts all the following four types of patterns. In addition, a pattern is synonymous with a solution required part.

<Pattern 1>
The pattern 1 is a combination of one loop that satisfies all of the following conditions and one or more “whisker nodes”. “Beard node” is a node at the end of the causal relationship.
• The loop is the “main loop”.
• The loop contains a “controllable node”.
• The controllable node is a child node of “beard node”.
As an example of the pattern 1, the loop R02 and the mustache node “Great East Japan Earthquake” in FIG.

<Pattern 2>
Pattern 2 is a combination of two loops that satisfy all of the following conditions.
• The loop is the “main loop”.
• The loop contains a “time lag link”.
• The loop contains a “controllable node”.
-The node with the two loops is shared.
As an example of the pattern 2, the loop R02 and the loop R04 in FIG.

<Pattern 3>
Pattern 3 is a combination of two loops that satisfy all of the following conditions.
One of the two loops is a “main loop” and includes a “time lag link”.
The other of the two loops is a “sub-loop”.
-The node with the two loops is shared.
At least one of the two loops includes a “controllable node”.
Examples of the pattern 3 include a combination of the loop R04 and the loop R05 in FIG. 10 and a combination of the loop R02 and the loop R03.

<Pattern 4>
Pattern 4 is a combination of two loops that satisfy all of the following conditions.
One of the two loops is a “main loop”.
The other of the two loops is a “sub-loop” and includes a “time lag link”.
-The node with the two loops is shared.
At least one of the two loops includes a “controllable node”.
An example of pattern 4 does not exist in FIG.

In step S302, the CLD display unit 21 determines a node to be highlighted. Specifically, first, the CLD display unit 21 gives points to all nodes based on the following rules.
(rule)
(1) When the node is a “beard node”, “1” is given to the node.
(2) When the node is a child node of the “beard node”, “1” is given to the node.
(3) When the node is included in the “main loop”, “1” is given to the node.
(4) When the node is included in the “sub-loop”, “1” is given to the node.
(5) If the node is included in the pattern extracted in step S301, “1” is given to the node.
(6) When the node is at the start or end point of the “time lag link”, “1” is given to the node.
(7) When the node is a “controllable node”, “1” is given to the node.
Note that the CLD display unit 21 may perform the “first” process only on the nodes included in the pattern extracted in step S301, instead of targeting all the nodes. In this case, the above rule “(5)” is not applied. Furthermore, the number of points given is not limited to “1”, and the number of points given for each rule may be different.

Second, the CLD display unit 21 adds up the given points.
Third, the CLD display unit 21 extracts all nodes whose total score is equal to or greater than a predetermined threshold.

  In step S303, the CLD display unit 21 acquires an unprocessed pattern. Specifically, the CLD display unit 21 acquires an unprocessed arbitrary pattern from the patterns extracted in step S301. The pattern acquired here is called a “target pattern”.

  In step S304, the CLD display unit 21 determines whether or not the acquired pattern is the pattern 1. Specifically, if the target pattern is “pattern 1” (step S304 “Yes”), the CLD display unit 21 proceeds to step S305, and otherwise (step S304 “No”) proceeds to step S308. .

  In step S305, the CLD display unit 21 determines whether the main loop is a virtuous loop. Specifically, the CLD display unit 21 proceeds to step S306 if the main loop included in the target pattern is a “good circulation loop” (step S305 “Yes”), and otherwise (step S305 “No”). ), The process proceeds to step S307.

In step S306, the CLD display unit 21 designates the following countermeasure candidate A as a countermeasure. The countermeasure is an advice to the user displayed in association with the solution required place.
<Countermeasure A>
"Please strengthen the child node of the beard node."
“Strengthening” is an action on the node to strengthen the rotation of the loop.

In step S307, the CLD display unit 21 designates the following countermeasure candidate B as a countermeasure.
<Countermeasure B>
“Suppress child nodes of beard nodes.”
“Inhibition” is an action on a node to weaken or stop the rotation of the loop.

  In step S308, the CLD display unit 21 determines whether or not the main loop is a virtuous loop. Specifically, the CLD display unit 21 proceeds to step S312 when the main loop included in the target pattern is a “good loop” (step S308 “Yes”), and otherwise (step S308 “No”). ), The process proceeds to step S309.

  In step S309, the CLD display unit 21 determines whether or not the main loop is a self-strengthening loop. Specifically, when the main loop included in the target pattern is a “self-enhanced loop” (step S309 “Yes”), the CLD display unit 21 proceeds to step S310, and otherwise (step S309 “No”). ), The process proceeds to step S311.

In step S310, the CLD display unit 21 designates the following countermeasure candidate C as a countermeasure.
<Countermeasure C>
"If the main loop contains controllable nodes, suppress controllable nodes."
"If both loops are self-enhanced loops or balanced loops and the sub-loop contains controllable nodes, suppress controllable nodes."
“If one of the two loops is a self-enhancing loop, the other is a balanced loop, and the sub-loop contains a controllable node, strengthen the controllable node.”
“If the main loop contains a controllable node, change the main loop to a balanced loop by working on the controllable node or by adding a new node.”

In step S311, the CLD display unit 21 designates the following countermeasure candidate D as a countermeasure.
<Countermeasure D>
"If the main loop contains controllable nodes, suppress controllable nodes."
"If both loops are self-enhanced loops or balanced loops and the sub-loop contains controllable nodes, suppress controllable nodes."
“If one of the two loops is a self-enhancing loop, the other is a balanced loop, and the sub-loop contains a controllable node, strengthen the controllable node.”

In step S312, the CLD display unit 21 designates the following countermeasure candidate E as a countermeasure.
<Countermeasure E>
"If the main loop contains a controllable node, strengthen the controllable node."
"If the main loop contains a controllable node and a time lag link, add a new node that becomes a child node of the controllable node and whose child node is the end point of the time lag link."
“If one of the two loops is a self-enhancing loop, the other is a balanced loop, and the sub-loop contains a controllable node, suppress the controllable node.”
“If both loops are self-enhanced loops or balanced loops and the sub-loop contains controllable nodes, reinforce the controllable nodes.”

  In step S313, the CLD display unit 21 determines whether there is an unprocessed pattern. Specifically, the CLD display unit 21 returns to step S303 when an unprocessed pattern remains (step S313 “Yes”), and proceeds to step S314 when it does not remain (step S313 “No”).

In step S314, the CLD display unit 21 highlights the pattern and the node. Specifically, the CLD display unit 21 displays a required solution location extraction screen 53 (FIG. 12) on the table type input / output device 3. On the solution required location extraction screen 53, the pattern determined in step S301 and the node determined in step S302 are highlighted (the center of the loop is highlighted in a cloud shape and the node is surrounded by a thick line).
When distinguishing the highlighted node included in the highlighted pattern and the non-highlighted node included in the highlighted pattern, the highlighted mode is changed. For example, when emphasizing a loop, a circular band is superimposed on the loop, and when emphasizing a node, the node graphic is a double line.

  In step S315, the CLD display unit 21 displays a countermeasure. Specifically, the CLD display unit 21 displays the countermeasure 172 specified in any one of steps S306, S307, and S310 to S312 in association with the pattern on the necessary solution extraction screen 53. Thereafter, the solution point extraction processing procedure is terminated, and the process proceeds to step S4 of the overall processing procedure.
