As shown in FIG. FIG. 7 is a diagram showing an example of an input screen 230 for status information on the sealing material and flange. FIG. 8 is a diagram showing an example of the answer screen 240. As shown in FIG.

Referring to FIG. 3, terminal device 20 displays login screen 200 in FIG. 4 and accepts input of a user ID and password (sequence SQ10). The login screen 200 includes a user ID input field 201, a password input field 202, and a button 203 for transitioning to the next screen. The user inputs the user ID in the input field 201 and inputs the password in the input field 202 .

When the user selects the button 203 after entering the user ID and password, the terminal device 20 transmits the user ID and password to the information processing server 10 (sequence SQ12).

The information processing server 10 performs user authentication of the terminal device 20 based on the user ID and password received from the terminal device 20 (sequence SQ14). Information processing server 10 transmits data for displaying input screen 210 of FIG. 5 to terminal device 20 (sequence SQ16).

The terminal device 20 displays an input screen 210, and condition information including the usage conditions of the gasket, the tightening control conditions when the gasket is sandwiched between a pair of flanges and tightened with a plurality of bolts and nuts, and the flange specifications. is received (sequence SQ18). The input screen 210 includes a use condition input field 211, a tightening control condition input field 212, a flange specification input field 213, and a button 214 for transitioning to the next screen.

Flange specifications include flange material, dimensions, seat shape, and the like. The user inputs the usage conditions in the input field 211 , the tightening control conditions in the input field 212 , and the flange specifications in the input field 213 .

When the button 214 is selected by the user after the condition information is input, the terminal device 20 transmits the condition information (usage conditions, tightening control conditions and flange specifications) on the usage environment to the information processing server 10 (sequence SQ20).

The information processing server 10 determines whether or not the usage environment corresponds to the recommended usage environment based on various conditions (sequence SQ22). Specifically, the information processing server 10 determines whether or not the use conditions match the previously defined recommended use conditions, and whether or not the tightening control conditions and the flange specifications match the previously defined recommended control conditions. judge. The information processing server 10 determines that the usage environment corresponds to the recommended usage environment when the usage conditions match the recommended usage conditions, the tightening control conditions match the recommended tightening control conditions, and the flange specifications match the recommended specifications. do. Otherwise, the information processing server 10 determines that the usage environment does not correspond to the recommended usage environment.

In the following explanation, the usage environment shall correspond to the recommended usage environment. If the usage environment does not correspond to the recommended usage environment, the information processing server 10 transmits data for displaying information indicating the recommended usage environment to the terminal device 20 . Thereby, the user of the terminal device 20 can confirm the recommended usage environment.

The information processing server 10 transmits data for displaying the inquiry screen 220 of FIG. 6 and the input screen 230 of FIG. 7 to the terminal device 20 (sequence SQ24). The data for displaying input screen 230 may be configured to be transmitted in the process of sequence SQ30, which will be described later.

The terminal device 20 displays an inquiry screen 220 and accepts input of inquiry information including the content of the defect and the damaged state of the gasket (sequence SQ26). The inquiry screen 220 includes a defect content selection column 221, a gasket damage state selection column 222, a simple answer column 223, and a button 224 for transitioning to the next screen. The user selects the contents of the defect related to the gasket and flange from the selection column 221 and selects the damaged state of the gasket from the selection column 222 . It should be noted that the content of the defect and the state of damage are examples, and are not limited to the content of FIG. 6 .

When the selection fields 221 and 222 are selected by the user, the terminal device 20 transmits inquiry information including the content of the defect and the state of damage to the information processing server 10 (sequence SQ28). In the example of FIG. 6, since the defect "liquid/gas leak" and the damage state "gasket unbroken" are selected, the inquiry information including these is sent.

Based on the inquiry information, the information processing server 10 generates a simple answer to the inquiry about the problem, and transmits the simple answer (sequence SQ30). In the example of FIG. 6, the information processing server 10 refers to the database of past cases, and in the case of the damage state "gasket non-destroyed", among many actual causes of the defect "liquid/gas leak", Send the most common cause as a short answer.

The terminal device 20 displays the information indicating the simple answer received from the information processing server 10 in the simple answer column 223 of FIG. 6 (sequence SQ32). In this case, the simple answer column 223 displays "insufficient tightening", which is the most probable cause of the liquid/gas leakage in the case where the gasket is not destroyed.

When the user selects the button 224, the terminal device 20 displays the status information input screen 230 of FIG. 7 (sequence SQ34). The input screen 230 includes a selection column 231 for selecting details (status information) of site conditions such as the appearance of gaskets and flanges and process conditions, and a button 232 for transitioning to the next screen.

The selection column 231 is a selection column for the appearance status of the gasket (asymmetrical defects, temporary fixing with tape, etc.) and the appearance status of the flange (flange diameter 1 m or more, suspected rust or damage on the flange surface, etc.) in the category "appearance". and a selection field. In addition, the selection column 231 is a section "process condition", and the fastening method (loosen to adjust to the specified torque, working time is faster than usual, etc.) and the condition change (fluid change, liquid soaking, etc.). include.

The terminal device 20 accepts input of status information including the appearance of gaskets and flanges and process conditions (sequence SQ36). Specifically, the user selects the content corresponding to the external appearance of the used gasket and flange and the content corresponding to the process condition from among the plurality of pieces of state information included in the selection field 231 . In the example of FIG. 7, "temporary tape fixation", "suspected bolt rust/deformation", "loosen and adjust to specified torque", and "with operation ON/OFF" are selected.

When the button 232 is selected by the user, the terminal device 20 transmits the selected status information to the information processing server 10 (sequence SQ38). Information processing server 10 generates response information to the inquiry information on the defect based on the inquiry information and the selected status information (sequence SQ40). Information processing server 10 transmits data for displaying answer screen 240 of FIG. 8 and answer information to terminal device 20 (sequence SQ42).

The terminal device 20 displays the answer screen 240 (sequence SQ44). The answer screen 240 includes an answer column 241 considering the selected situation information, a coping video column 242, a recommended product link area 243, a technical document link area 244, and a button for transitioning to detailed information. 245 and a button 246 for entering the evaluation result for the final answer.

The final answer is displayed in the answer column 241. The moving image field 242 displays a moving image of a remedy for the problem related to the cause displayed in the answer field 241 . When the link area 243 is selected, a transition is made to a Web page of products recommended to prevent the occurrence of this problem. When the link area 244 is selected, a transition is made to a Web page of technical data useful for preventing the occurrence of this problem. Selecting button 245 displays detailed information. When the button 246 is selected, a transition is made to a screen for inputting the evaluation result for the final answer (cause of trouble) displayed in the answer column 241 .

The answer field 241 in FIG. 8 displays "looseness" as the cause of the problem, and the simple answer field 223 in FIG. 6 displays "insufficient tightening" as the cause of the problem. is different. "Looseness" indicates loosening of the tightening of the flange bolts due to process variation. "Insufficient tightening" originally indicates that the tightening force when tightening the flange with the bolt was insufficient.

The content of the answer column 241 is considered to be more accurate than the content of the simple answer column 223 because it is the content of the answer that takes into consideration the situation information by the user. Therefore, the user confirms whether or not the cause of the problem displayed in the answer column 241 matches the actual cause. For example, if they match, the user selects the button 246 to transition to an evaluation input screen (not shown) and input an evaluation result indicating that the content of the answer is correct. On the other hand, if they do not match, the user inputs an evaluation result indicating that the content of the answer is incorrect on the evaluation input screen. The terminal device 20 transmits the input evaluation result to the information processing server 10 . The evaluation result is fed back to the process when the information processing server 10 generates answer information. This enables the information processing server 10 to generate highly accurate answer information.

According to the information processing system 1000 described above, by inputting the status of the seal material and the flange, an appropriate answer to the inquiry about the defect can be quickly provided without depending on the knowledge of the respondent. Therefore, even if there is no skilled person with knowledge and skills, there is no delay in responding to the situation, and it is possible to prevent the situation from becoming serious and serious trouble from occurring.

<Response information generation method>
FIG. 9 is a diagram showing an example of a table used by the information processing server 10. As shown in FIG. FIG. 9 shows tables 310 and 320 corresponding to the contents of the trouble "liquid/gas leakage".

The table 310 is association information that associates the damage state, answer candidates for the cause of the failure, and the degree of association R1 between the damage state and the answer candidate.

The damage state "gasket failure" is associated with the answer candidates "erosion" and "compression/tear", and the damage state "gasket non-rupture" is associated with the answer candidates "insufficient tightening", "unintended uneven tightening" and "Looseness" is associated. All candidate answers are associated with the damage state "Undistinguishable". Answer candidates "erosion", "compression/tear", "insufficient tightening", "unintended partial tightening", and "looseness" are classified into categories A to E, respectively. Each answer candidate is associated with a degree of relevance R1.

The degree of relevance R1 is a value that indicates the extent to which the damage state and answer candidates are related. The larger the value of the degree of association R1, the higher the association between the damage state and the cause indicated by the answer candidate. For example, if the content of the defect is "liquid/gas leakage" and the damage state is "gasket destruction", the relevance of the answer candidate "compression/tear" is higher than the relevance R1 (that is, 0.1) of the answer candidate "erosion". The degree of relevance R1 (that is, 0.2) is larger. Therefore, if the problem is "gas leak" and the damage state is "gasket fracture", the cause of the problem is more likely to be "compression/tear" than "erosion".

In addition, the sum P1 of the relevance R1 of each answer candidate ("erosion" and "compression/tear") corresponding to "gasket destruction" is "0.3", and each answer corresponding to "gasket non-destruction" The sum P2 of the relevance R1 of the candidates (“insufficient tightening”, “unintended uneven tightening” and “looseness”) is “0.6”, and the relevance R1 of each answer candidate corresponding to “distinction unknown” is The sum P3 is "0.1". Since the sum P2 is the largest among the sums P1 to P3, it can be said that in the case of the failure of "liquid/gas leakage", the possibility of "gasket non-destruction" is the highest. In this embodiment, the added value of the sums P1 to P3 is adjusted to be "1.0", but the present invention is not limited to this.

A table 320 is association information in which, for each of a plurality of pieces of situation information, the situation information, (classification of) answer candidates, and the degree of association R2 between the situation information and the answer candidates are associated. The degree of relevance R2 is a value that indicates how much the situation information and answer candidates are related. The answer candidate "erosion" of the category A is associated with the situation information "asymmetric loss", "tape temporary fixation", "flange diameter 1 m or more", and "fluid change (concentration/flow rate)". The answer candidate "compression/tear" in category B is associated with status information "paste application", "flange surface rust/damage suspected", and "loosen and adjust to specified torque". The same applies to the answer candidates "insufficient tightening", "unintended uneven tightening", and "looseness" in categories C, D, and E.

Note that the relevance R1 of the answer candidate X associated with the damage state in the table 310 matches the sum of the relevance R2 of each answer candidate X associated with the situation information in the table 320. For example, the situation information associated with the answer candidate "erosion" of category A is set to "asymmetric loss", "tape temporary fixing", "flange diameter 1 m or more", "fluid change (concentration / flow rate)" The degrees of association R2 are respectively "0.01", "0.04", "0.04" and "0.01". The sum of these degrees of relevance is “0.1”, which matches the degree of relevance R1 of the answer candidate “erosion” in table 310 . The same applies to other categories B to E. However, the degree of association R1 and the degree of association R2 do not have to satisfy such a relationship.

FIG. 10 is a diagram for explaining an example of a method for generating reply information. Referring to FIG. 10 , information processing server 10 reads a table corresponding to inquiry information received from terminal device 20 . In the example of FIG. 10, the contents of the defect included in the inquiry information are "liquid/gas leakage", so the tables 310 and 320 are read.

Based on the table 310, the information processing server 10 identifies each answer candidate associated with the damage state "gasket not destroyed" included in the inquiry information. In this case, answer candidates "insufficient tightening", "unintended uneven tightening" and "looseness" are specified.

The information processing server 10 identifies the answer candidate with the highest set degree of association R1 among the identified answer candidates, and outputs the answer candidate as a simple answer to the inquiry (that is, the terminal device 20 to). In this case, since the degree of association R1 (that is, 0.3) set for the answer candidate "insufficient tightening" is the highest, "insufficient tightening" is output as a simple answer. This process corresponds to sequence SQ30 in FIG.

Next, the information processing server 10 identifies answer candidates associated with each piece of situation information received from the terminal device 20 based on the table 320 . In the example of FIG. 10, status information "paste applied", "flange diameter 1 m or more", "working time earlier than usual", and "thermal cycle present" are received. Therefore, the answer candidates "compression/tear", "erosion", "undertightening" and "looseness" associated with these status information are identified.

The information processing server 10 determines whether the answer candidates associated with the situation information identified using the table 320 exist among the plurality of answer candidates associated with the damage state identified using the table 310. to judge. In the example of FIG. 10 , the information processing server 10 determines that the answer candidates “insufficient tightening” and “looseness” identified using the table 320 exist among the plurality of answer candidates identified using the table 310 .

The information processing server 10 generates answer information to the inquiry based on the determination result, and outputs the answer information. Specifically, the information processing server 10 selects the existing answer candidates "insufficient tightening" and "looseness" as final answers to the inquiry, and outputs answer information including the final answers. The answer information further includes detailed information and suggestion information related to the final answer.

The detailed information is the detailed cause (e.g., "low Occurrence of creep relaxation due to surface pressure”). For example, according to the detailed information, it is suggested that the work time was earlier than usual and the flange was insufficiently tightened, so creep relaxation progressed due to the low surface pressure, and the gasket expanded and contracted due to fluctuations in the heat cycle (process fluctuations). be done. As a result, it is suggested that a liquid/gas leak occurred.

Suggestion information is advice information (for example, "fastening method confirmation”).

Note that if there is no answer candidate identified using the table 320 among the plurality of answer candidates identified using the table 310, the information processing server 10 selects the answer candidate identified as the simple answer as the final answer. output as

FIG. 11 is a diagram for explaining another example of the response information generation method. Referring to FIG. 11, tables 310 and 320 are read as in FIG. It is the same as the example of FIG. 10 in that "insufficient tightening" is output as a simple answer.

In the example of FIG. 11, the information processing server 10 has received the status information "tape temporary fastening", "flange surface rust/damage suspected", "loosen and adjust to specified torque", and "thermal cycle present". Therefore, the answer candidates "erosion", "compression/tear", and "looseness" associated with these context information are identified.

In the example of FIG. 11, the information processing server 10 determines that the answer candidate "looseness" specified using the table 320 exists among the multiple answer candidates specified using the table 310. The information processing server 10 selects the identified answer candidate “loosening” as the final answer to the inquiry information, and outputs answer information including the final answer. In this way, a final answer "looseness" different from the simple answer "insufficient tightening" is output.

FIG. 12 is a diagram showing another example of the table used by the information processing server. FIG. 12 shows tables 410 and 420 corresponding to the content of the defect "contamination with foreign matter". Table 410 has a similar structure to table 310 of FIG. 9, and table 420 has a similar structure to table 320 of FIG. The difference between table 410 and table 310 is the degree of association between damage states and answer candidates. The difference between table 420 and table 320 is the degree of association between the situation information and the answer candidates. In this way, it is understood that the "relevance level" differs according to the content of the defect.

FIG. 13 is a diagram for explaining another example of the reply information generation method. In the example of FIG. 13, the contents of the problem included in the inquiry information are "contamination of foreign matter", so tables 410 and 420 are read.

Based on the table 410, the information processing server 10 identifies the answer candidates "erosion" and "compression/tear" associated with the damage state "gasket fracture".

The information processing server 10 outputs, as a simple answer, "compression/truncation" with the highest set degree of association R1 among the specified answer candidates.

Next, the information processing server 10 identifies answer candidates associated with each piece of situation information received from the terminal device 20 based on the table 420 . In the example of FIG. 13, the status information "tape temporary fixing", "bolt rust/deformation suspected", "loosen and adjust specified torque", and "operation ON/OFF" are received. Therefore, the answer candidates "erosion", "insufficient tightening", "compression/tear", and "looseness" associated with these status information are identified.

The information processing server 10 determines that the answer candidates "erosion" and "compression/tear" specified using the table 420 exist among the multiple answer candidates specified using the table 410.

The information processing server 10 selects the answer candidate associated with the highest degree of relevance R2 from among the answer candidates "erosion" and "compression/tear" as the final answer to the inquiry, and outputs answer information including the final answer. . In this case, since the relevance R2 (that is, 0.15) corresponding to the answer candidate "erosion" is higher than the relevance R2 (that is, 0.1) corresponding to "compression/tear", Erosion” is selected as the final answer. In this way, the configuration may be such that the final answer is narrowed down to one and output using the degree of association R2. As in the example of FIG. 10, when there are two or more answer candidates, the configuration may be such that two or more answer candidates are selected as the final answer. In this case, "erosion" and "compression/tear" are chosen as final answers.

The detailed information includes the detailed cause "contamination of tape components" set in the status information "tape temporary fixing" associated with the answer candidate "erosion" corresponding to the final answer. According to the detailed information, as a result of temporarily fixing the gasket with tape, erosion occurred due to obstruction of fluid flow and the induction of stationary vortices, which not only mixed the temporarily fixed tape components but also destroyed the gasket. is suggested.

FIG. 14 is a diagram for explaining another example of the response information generation method. In the example of FIG. 14, tables 410 and 420 are read as in FIG.

In the table 410, all answer candidates are associated with the damage state "undistinguishable". Therefore, since the information processing server 10 cannot narrow down the answer candidate to one, it outputs "reason unknown" as a simple answer.

Next, the information processing server 10 identifies answer candidates associated with each piece of situation information received from the terminal device 20 based on the table 420 . In the example of FIG. 14, the status information "bolt rust/deformation suspected", "fastened in an unreasonable position", and "fluid change (concentration/flow rate)" is received. Therefore, answer candidates "insufficient tightening", "unintended uneven tightening", and "erosion" associated with these pieces of situation information are specified.

The information processing server 10 determines that answer candidates “insufficient tightening”, “unintended partial tightening”, and “erosion” identified using the table 420 exist among the plurality of answer candidates identified using the table 410. to decide. The information processing server 10 selects the answer candidate "erosion" associated with the highest degree of relevance R2 among the answer candidates "insufficient tightening", "unintended partial tightening" and "erosion" as the final answer to the inquiry, Output the answer information including the final answer.

The detailed information is set to the status information "fluid change (concentration/flow rate)" associated with the answer candidate "erosion" corresponding to the final answer. including.

<Functional configuration>
FIG. 15 is a block diagram showing an example of the functional configuration of the information processing server 10. As shown in FIG. Referring to FIG. 15, information processing server 10 has, as its main functional configuration, a first storage unit 150, a first information input unit 152, a first specifying unit 154, a second storage unit 156, a status information input unit 158, a second specifying unit 160, a first determination unit 162, an output control unit 164, a second information input unit 166, a second determination unit 168, an evaluation result input unit 170, and a setting unit 172 including. Configurations other than the first storage unit 150 and the second storage unit 156 among these functions are implemented by the processor 101 of the information processing server 10 executing a program stored in the memory 103, for example. Some or all of these functions may be configured to be implemented by hardware. First storage unit 150 and second storage unit 156 are implemented by memory 103 .

The first storage unit 150 stores inquiries about the damage state of the sealing material (eg, gasket) used to fasten the flange (eg, “damage state” in the table 310 of FIG. 9) and defects that occurred in the sealing material and the flange. First association information (for example, table 310).

The first information input unit 152 inputs the details of the defect that occurred in the sealing material and the flange (for example, "details of defect" on the inquiry screen 220 in FIG. 6) and the current state of damage to the sealing material (for example, the (e.g., receive inquiry information).

The first identifying unit 154 identifies multiple answer candidates associated with the damage state included in the inquiry information based on the first association information. For example, the first identifying unit 154 identifies a plurality of answer candidates (“insufficient tightening,” “unintended uneven tightening,” and “looseness”) associated with the damage state “gasket not destroyed” (see FIG. 10). .

The second storage unit 156 stores, for each of a plurality of pieces of situation information (for example, “details of situation” in the table 320 in FIG. 9) relating to the appearance and process conditions of the sealant and flange, the situation information and answer candidates (for example , answer candidate corresponding to "classification" in table 320) and second association information (for example, , table 320).

The situation information input unit 158 accepts input of one or more situation information out of a plurality of situation information (for example, receives situation information). Specifically, situation information input unit 158 accepts an input of one or more situation information selected by the user from a plurality of situation information prepared in advance. For example, the status information input unit 158 receives status information selected by the user from a plurality of status information, such as "temporary tape fixing", "suspicious bolt rust/deformation", "loosen and adjust to specified torque", and "operation ON". /OFF" is accepted (see FIG. 7).

The second identifying unit 160 identifies answer candidates associated with each of the received one or more pieces of situation information based on the second association information. For example, the second identification unit 160 identifies the answer candidate “compression/tear” associated with the situation information “paste application”, “flange diameter 1 m or more”, “working time is earlier than usual”, and “thermal cycle is present”. ", "erosion", "undertightening" and "looseness" (see Figure 10).

The first determination unit 162 selects, among the plurality of answer candidates identified by the first identification unit 154 (for example, the plurality of answer candidates associated with the damage state identified based on the table 310), the second identification It is determined whether or not there is an answer candidate identified by unit 160 (for example, an answer candidate associated with the situation information identified based on table 320) (see FIG. 10).

The output control unit 164 outputs (transmits) answer information to the inquiry information based on the determination result of the first determination unit 162 . In a certain aspect, when there is an answer candidate specified by second specifying unit 160 among the plurality of answer candidates specified by first specifying unit 154, output control unit 164 selects the answer candidate specified by second specifying unit 160. The candidate answer is selected as the final answer. In the example of FIG. 10, since the answer candidates "insufficient tightening" and "looseness" identified using the table 320 exist among the plurality of answer candidates identified using the table 310, the output control unit 164 executes " "Insufficient tightening" and "looseness" are selected as final answers, and answer information including the final answers is output.

In another aspect, when there are two or more answer candidates specified by the second specifying unit 160 among the plurality of answer candidates specified by the first specifying unit 154, the output control unit 164 selects the two or more The answer candidate associated with the largest second degree of relevance among the answer candidates is selected as the final answer. In the example of FIG. 13, two answer candidates “erosion” and “compression/tear” specified using the table 420 exist among the multiple answer candidates specified using the table 410. Therefore, the output control unit 164 selects the answer candidate "erosion" associated with the highest degree of relevance R2 from among the two answer candidates as the final answer, and outputs answer information including the final answer.

In yet another aspect, the output control unit 164 outputs the answer candidate with the highest first relevance among the plurality of answer candidates identified by the first identification unit 154 as a simple answer to the inquiry information. In the example of FIG. 10, among the multiple answer candidates "insufficient tightening", "unintended uneven tightening" and "looseness" specified based on the table 310, the degree of relevance R1 set to the answer candidate "insufficient tightening" is the largest. Therefore, the output control unit 164 outputs "insufficient tightening" as a simple answer.

In yet another aspect, if the answer candidate specified by the second specifying unit 160 does not exist among the plurality of answer candidates specified by the first specifying unit 154, the output control unit 164 selects the answer as a simple answer. Output the candidate answer as the final answer.

The second information input unit 166 is used to input seal material usage conditions (for example, “use conditions” on the input screen 210 in FIG. 5) and flange-related tightening control conditions (for example, “tightening control conditions” on the input screen 210). and the specification of the flange (for example, "flange specification" on the input screen 210).

The second judgment unit 168 judges whether or not the usage environment of the sealing material and the flange corresponds to the recommended usage environment based on the condition information. Specifically, if each of the use conditions and the tightening control conditions included in the condition information matches the corresponding recommended conditions and the flange specifications match the recommended specifications, the second determination unit 168 determines that the use environment is Judging that it corresponds to the recommended usage environment. Otherwise, the information processing server 10 determines that the usage environment does not correspond to the recommended usage environment. In one aspect, first information input unit 152 accepts input of inquiry information when the usage environment corresponds to the recommended usage environment.

The evaluation result input unit 170 accepts input of evaluation results including whether or not the final answer is correct. The setting unit 172 sets the value of the second degree of association associated with the answer candidate corresponding to the final answer based on the evaluation result.

For example, as shown in FIG. 11, when the final answer is "looseness", the setting unit 172 sets the degree of relevance R2 associated with the answer candidate "looseness" (for example, "degree of relevance R2" of category E in table 320). set. If the final answer is correct, the setting unit 172 increases the value of the second degree of relevance associated with the answer candidate corresponding to the final answer (for example, "relevance R2" of category E in table 320). In this case, the relationship between the situation information and the causes indicated by the answer candidates in the table 320 increases. If the final answer is incorrect, the setting unit 172 reduces the value of the second degree of association associated with the answer candidate corresponding to the final answer. In this case, the relationship between the situation information and the causes indicated by the answer candidates in the table 320 is low. By feeding back the evaluation results in this way, it is possible to select answer candidates with high accuracy.

<Advantages>
According to this embodiment, it is possible to quickly provide an appropriate answer to an inquiry about a problem with the sealing material and the flange. In addition, even if there is no skilled person with knowledge and skills, there is no delay in responding to the situation, and it is possible to prevent the situation from becoming serious and serious trouble from occurring.

<Other embodiments>
(1) In the above-described embodiment, the information processing server 10 may be configured to generate an answer to the inquiry in consideration of the image data of the sealing material and the flange provided from the terminal device 20 . For example, the information processing server 10 compares the provided image data of the sealant with standard image data prepared in advance, and determines that the sealant is discolored more than usual. In this case, the information processing server 10 generates the final answer in consideration of the discoloration of the sealing material.

9, the degree of relevance of the situation information "liquid permeates" associated with the answer candidate "insufficient tightening" and the degree of relevance of the situation information "thermal cycle present" associated with the answer candidate "looseness" are consistent. When narrowing down the final answer to only one, it is not possible to determine which of the answer candidates "insufficient tightening" and "looseness" should be selected as the final answer based only on the degree of relevance. Here, it is assumed that discoloration of the sealing material occurs when there is a thermal cycle. Therefore, the information processing server 10 selects the answer candidate "looseness" associated with the status information "with heat cycle" as the final answer based on the determination result that the sealing material is discolored.

Note that the information processing server 10 may be configured to generate a final answer in consideration of sensor data, which are various measurement results of the sealing material and the flange.

(2) In the above-described embodiment, a configuration was described in which the degree of relevance set in the situation information was used to generate the final answer to the inquiry. A trained model that estimates the final answer may be generated. For example, the information processing server 10 is configured to perform reinforcement learning.

Q-learning is known as a representative method of reinforcement learning. In Q-learning, if the action value Q of action a with the highest Q value at time t+1 is greater than the action value Q of action a executed at time t, action value Q is increased; Decrease the value Q. That is, the action value function Q(s, a) is updated so that the action value Q of action a at time t approaches the best action value at time t+1. As a result, the best behavioral value in a certain environment is propagated to the behavioral value in the previous environment.

The learning unit of the information processing server 10 uses a data acquisition unit that acquires learning data including the status information received from the terminal device 20 and the final response to the inquiry, and the learning data to obtain information from one or more pieces of situation information. and a model generator for generating a trained model for estimating the final answer. Known algorithms such as supervised learning, unsupervised learning, and reinforcement learning can be used as the learning algorithm used by the model generation unit.

The input parameters of the learning part are state variables. In this embodiment, the state variables include status information and final response. The output parameter of the learning device is the action value. The action value is the final answer that maximizes future rewards.

The information processing server 10 acquires the situation information and the final answer as learning data. The information processing server 10 determines whether to increase or decrease the reward based on the reward criteria, the status information and the final answer. Specifically, the reward criteria increase the reward if the final answer is correct (e.g., award a "+1") and decrease the reward if it is incorrect (e.g., "- 1” reward).

When the obtained final answer is set in the state indicated by the obtained status information, the information processing server 10 increases the reward if the final answer is correct, and reduces the reward if the final answer is incorrect. The information processing server 10 repeatedly executes a process of acquiring learning data and a process of increasing or decreasing the reward, and stores the generated action-value function Q(s _t , at ₎ as a trained model in the memory 103. Remember.

The information processing server 10 acquires status information from the terminal device 20 . The information processing server 10 estimates the final answer by inputting the situation information into the learned model stored in the memory 103 . The information processing server 10 outputs the estimated final answer to the terminal device 20 .

Such programs shall be recorded on non-temporary computer-readable recording media such as flexible disks attached to computers, CD-ROMs (Compact Disk Read Only Memory), secondary storage devices, main storage devices and memory cards. can also be provided as a program product. Alternatively, the program can be provided by recording it in a recording medium such as a hard disk built into the computer. The program can also be provided by downloading via a network.

The program may be one that calls necessary modules out of the program modules provided as part of the computer's operating system (OS) in a predetermined sequence at a predetermined timing to execute processing. In that case, the program itself does not include the above module, and the process is executed in cooperation with the OS. Programs that do not include such modules may also be included in the programs according to the present embodiment. Also, the program according to the present embodiment may be provided by being incorporated into a part of another program. Even in that case, the program itself does not include the modules included in the other program, and the processing is executed in cooperation with the other program.
