The repair information includes, for each repair of the product, generation information of a defect of the product and information of the repaired component. When a first point-in-time object component, which is an object to be repaired at the first point in time, and a second point-in-time object component, which is an object to be repaired at the second point in time, coincide with each other. The re-repair determination unit determines that the repair performed at the first point in time is a re-repair if the defect content determined on the basis of the occurrence information of the defect for the target component at the first point in time coincides with the defect content determined on the basis of the occurrence information of the defect for the target component at the second point in time, or if the defect content coincides with the defect content determined on the basis of the occurrence information of the defect for the target component at the second point in time.

Description

Technical Field

[0001] The present invention relates to a repair information providing device and a repair information providing method that provide information related to product repair. Background Art

[0002] As such a device, there is a device that provides information related to a vehicle repair method. For example, in the device described in Patent Document 1, a symptom code indicating the type of a defect occurring in the vehicle is determined, and a plurality of corresponding operation codes corresponding to the determined symptom code are extracted. Then, by referring to the corresponding operation code and repair date in the past repair history table, a corresponding operation code indicating an operation that has not been performed in the past six months is output as a repair method with a higher priority.

[0003] When a product fails or has a defect, it is best to correctly identify the cause of the defect and the necessary measures to eliminate the defect in one repair. However, when it comes to re-repair, it is necessary to quickly verify the main cause of the re-repair and take necessary measures. However, there are various situations that lead to re-repair, so it is difficult to accurately determine whether each repair is a re-repair. For example, as in the device described in Patent Document 1, it is difficult to accurately determine only from the point of view that different repairs are performed for the same symptom.

[0016] Figure 7 It is shown by Figure 1 A flowchart of an example of a process executed by a repair information providing device. DETAILED DESCRIPTION

[0017] The following reference Figure 1 to Figure 7 The embodiment of the present invention is described. The repair information providing device of the embodiment of the present invention provides information related to the repair of a product such as a vehicle, and in particular provides information related to whether each repair is a re-repair. In the case of a defect such as a malfunction of a product, it is preferable to correctly determine the cause of the defect and the necessary treatment so as to eliminate the defect in one repair, but when it comes to the point of re-repair, it is necessary to quickly verify the main cause of the re-repair and take necessary countermeasures.

[0018] Figure 1 This is a diagram used to illustrate the main reasons for re-repairing a product. Figure 1 As shown in the figure, the situations that require re-repair are roughly divided into the situation where the defect is not eliminated by the first repair and the situation where the defect is eliminated once by the first repair, but the same defect occurs again. The main reasons for the situation where the defect is not eliminated by the first repair are: the diagnosis ability of the repair person is insufficient, and the cause of the defect and the necessary treatment cannot be correctly determined, or the diagnosis is difficult in itself due to the low reproducibility of the defect. The main reasons for the situation where the same defect occurs again are: the cause part that is the cause of the defect is not repaired, but only the damaged part that is affected (damaged) by the cause part and causes the defect is repaired, or the product itself has a quality problem.

[0019] Figure 2 This is a diagram for explaining an example (situation) of re-repair. Figure 1 , 2 As shown in the figure, when the same defective symptom occurs again or continues to occur during the first repair and the second repair, when it is clear that the same part should be repaired or when it is difficult to determine other repair parts, the same part may be repaired (Case A). Such repair is considered to be a re-repair to eliminate the defect that was not eliminated by the first repair.

[0020] When the defect is not eliminated in the first repair, and a different defective symptom appears in the second repair, that is, a related defective symptom or a worsened defective symptom appears, the same part is sometimes repaired again (Example B). For example, when a shock absorber, which is a vehicle component, leaks oil, an abnormal noise sometimes occurs as a related defective symptom or a worsened defective symptom. Such repairs are also considered re-repairs. When the defect is not eliminated in the first repair, and a new defective symptom different from the first repair appears in the second repair, and a different part is repaired, it is not considered re-repairs.

[0021] If the defect is not eliminated in the first repair and the same defect occurs in the second repair, it is possible that the first repair site is inappropriate, so sometimes a different site from the first repair is repaired (Case C). Such repair is also considered re-repair.

[0022] In this embodiment, the repair information providing device is constructed as follows so as to Figure 2 The example of all re-repairs shown can accurately determine whether each repair is a re-repair, and provide information related to the repair of the product.

[0023] Figure 3 1 is a block diagram schematically showing an example of the overall structure of a repair information providing system 100 including a repair information providing device (hereinafter referred to as a device) 10 according to an embodiment of the present invention. Figure 3 As shown, the repair information providing system 100 includes an apparatus 10 and an information input terminal 20 installed in a shop or the like that performs repairs on a vehicle or the like. The information input terminal 20 may also include a device managed by a business entity that manufactures a vehicle or the like. The apparatus 10 and the information input terminal 20 are connected to each other in a communicative manner via a communication network 30 including a WAN (Wide Area Network) such as a LAN (Local Area Network) and the Internet.

[0024] The device 10 is composed of a computer having a CPU (processor), a ROM (read only memory), a RAM (random access memory), other peripheral circuits, etc. The device 10 has an information acquisition unit 11, a re-repair determination unit 12, and an information output unit 13 as a functional structure of the processor, and has an information storage unit 14 as a functional structure of the memory. That is, the processor of the device 10 functions as the information acquisition unit 11, the re-repair determination unit 12, and the information output unit 13, and the memory of the device 10 functions as the information storage unit 14. The device 10 can be configured as a single server device, a distributed server device, or a distributed virtual server device set up in a cloud environment.

[0025] The information input terminal 20 is composed of a device such as a personal computer or a tablet terminal that is installed in a shop that repairs products such as vehicles and is connectable to the communication network 30. Repair information related to the repair of the product is input into the information input terminal 20 by a staff of the shop and the like. The repair information input into the information input terminal 20 is sent to the device 10 through the communication network 30 and managed.

[0026] Figure 4 is a diagram used to illustrate repair information. Figure 4 As shown, the repair information includes an identification number (in Figure 4In the example, the acceptance number) and the identification number for specifying the product that has been repaired (in Figure 4 In the example of , it is the vehicle identification number). In addition, it includes information indicating the date and time when the repair was performed and the amount of product used (in Figure 4 In the example, the repair acceptance date and the cumulative driving distance).

[0027] Repair information also includes information for identifying the defective content (defective symptoms) of the product (in Figure 4 In the example, the symptom code) and information to identify the actual repaired part (in Figure 4 In the example, the representative part number and the replacement part number are used). The "representative part" is a single part that has been repaired as the cause of the defect, and the "replacement part" is a part that has been replaced as the representative part has been repaired. There are also cases where no parts are replaced, and there are also cases where there are multiple replacement parts. In addition to replacing a defective part with a new one, repair also includes removing the defective part for inspection, repair, cleaning, processing, and any other treatment before installing it on the product again. The part number includes multiple character strings, a part of which (such as the first digit) determines the mounting location and major category of the part, and a part of which (such as the first five digits) determines the part itself. The symptom code also contains multiple character strings, a part of which (such as the first three digits) determines the defective symptom.

[0028] The information acquisition unit 11 of the device 10 acquires the repair information transmitted from the information input terminal 20. The repair information acquired by the information acquisition unit 11 is stored in the information storage unit 14 and accumulated.

[0029] The re-repair determination unit 12 determines whether the repair performed on the product at the first time point is a re-repair for eliminating the defect of the product that was not eliminated by the repair performed at the second time point before the first time point, based on the repair information acquired by the information acquisition unit 11. For example, when the repair information of a new repair is acquired by the information acquisition unit 11, the repair information of the past repair performed on the same product is extracted from the repair information stored and accumulated in the information storage unit 14, and it is determined whether it meets the following conditions. Figure 2 Alternatively, the repair information of a series of repairs performed on each product is extracted from the repair information stored and accumulated in the information storage unit 14, and for each combination of the repair information, it is determined whether it meets the requirements. Figure 2 Example of reconditioning shown.

[0030] Figure 51 is a diagram for explaining the re-repair determination performed by the re-repair determination unit 12. The re-repair determination unit 12 first extracts the repair information of the repair performed on the product at the first time point and the repair information of the repair performed at the second time point before the first time point from the repair information acquired by the information acquisition unit 11 and stored in the information storage unit 14. More specifically, a combination of repair information that has the same identification number (e.g., vehicle identification number) for identifying the product and different repair periods and product usage amounts (e.g., cumulative mileage) is extracted.

[0031] In this case, the period from the second time point to the first time point can be limited to within a prescribed period, and the repair information can be extracted. Figure 2 In the case of the example of re-repair shown, repairs that have passed a prescribed period since the last repair are generally not considered re-repair. The prescribed period can also be determined based on time (e.g., half a year, etc.), or based on the amount of use of the product (e.g., mileage of 10,000 km, etc.). The prescribed period can also be determined for each component, for example, based on the service life of each component.

[0032] Next, if Figure 5 As shown, the re-repair determination unit 12 compares the representative part number (the part number of the representative part at the first time point) contained in the extracted repair information at the first time point with the representative part number (the part number of the representative part at the second time point) contained in the repair information at the second time point. In addition, the replacement part number (the part number of the replacement part at the first time point) contained in the repair information at the first time point and the replacement part number (the part number of the replacement part at the second time point) contained in the repair information at the second time point are compared. When the first five digits of the part numbers are consistent, the repair object at the first time point, i.e., the first time point object part (the first time point representative part or the first time point replacement part) and the repair object at the second time point, i.e., the second time point object part (the second time point representative part or the second time point replacement part) are the same part. In this case, it meets the requirement. Figure 2 The repair at the first time point is determined to be a re-repair of the repair at the second time point. It should be noted that, regarding the replacement parts, any one of the parts replaced at the first time point and any one of the parts replaced at the second time point can be the same part.

[0033] The re-repair determination unit 12 also compares the symptom code contained in the repair information at the first time point (the symptom code at the first time point) with the symptom code contained in the repair information at the second time point (the symptom code at the second time point). When the first three digits of the symptom code are consistent, it can be said that the same adverse symptom as at the second time point is reoccurring or continuing at the first time point. In addition, even if the first five digits of the part number are inconsistent, when the first digit of the part number is consistent, the target part at the first time point and the target part at the second time point are parts with the same mounting location and major classification. Therefore, when the first three digits of the symptom code are consistent with the first digit of the part number, it can be said that there is a correlation between the repair at the first time point and the repair at the second time point. In this case, as a compliance Figure 2 In the case of Example A or Example C, it is determined that the repair at the first time point is a re-repair of the repair at the second time point. It should be noted that with respect to the replacement parts, any one of the replacement parts at the first time point and any one of the replacement parts at the second time point can be parts with the same mounting location and major category.

[0034] The determination result of the re-repair determination unit 12 is stored in the information storage unit 14. More specifically, the information of the number of times the re-repair has been performed is added to the repair information at the second time point in the repair information stored in the information storage unit 14, and the repair information at the first time point performed as the re-repair is associated to update the repair information.

[0035] The re-repair determination unit 12 further calculates (determines) a score value indicating the probability that the repair at the first time point is a re-repair. That is, when the probability that the repair at the first time point is a re-repair is the highest, that is, when the first five digits of the part number of the representative part at the first time point and the representative part at the second time point are the same, the highest first score value is calculated (in Figure 5 In the example, it is 1000 points.) If the first five digits of the part number of the replaced part at the first time point and the replaced part at the second time point are the same, calculate the second score value (in Figure 5 In the example, it is 100 points.) If the first digit of the part number and the first three digits of the symptom code of the representative part at the first time point and the representative part at the second time point are the same, calculate the third score value (in Figure 5 In the example, it is 10 points.) If the first digit of the part number and the first three digits of the symptom code of the part replaced at the first time point and the part replaced at the second time point are the same, calculate the fourth score value (in Figure 5 In the example, it is 1 point).

[0036] The score calculated by the re-repair determination unit 12 is stored in the information storage unit 14. More specifically, the score calculated by the re-repair determination unit 12 is added to the combination of the repair information at the first time point and the repair information at the second time point, and the repair information stored in the information storage unit 14 is updated.

[0037] Figure 6 FIG. 1 is a diagram showing an example of a re-repair determination result performed by the re-repair determination unit 12, and shows an example of a series of repairs performed on vehicles having the same vehicle identification number at different times of accumulated travel distance. Figure 6 As shown, in repair 1a and repair 2, the first five digits of the part number representing the component do not match, but the first five digits of the part number of the replaced component match, so repair 2 is determined to be a re-repair of repair 1a, and 100 points are calculated as the score value. In repair 1a and repairs 3 and 4, the first digit of the part number representing the component and the first digit of the part number of the replaced component do not match, so repairs 3 and 4 are determined not to be re-repairs of repair 1a. In this case, the information that a re-repair was performed is added to the repair information of repair 1a, and the repair information of repair 2 performed as a re-repair is linked to update the repair information.

[0038] In repair 1b, repairs 2 and 3, the first five digits of the part number representing the component are the same, so repairs 2 and 3 are determined to be re-repairs of repair 1b, and 1000 points are calculated as the score value. In repair 1b and repair 4, the first digit of the part number representing the component is also different, but the first digit of the part number of the replaced part and the first three digits of the symptom code are the same, so repair 4 is determined to be a re-repair of repair 1b, and 1 is calculated as the score value. In this case, the information that three re-repairs were performed is added to the repair information of repair 1b, and the repair information of repairs 2, 3, and 4 performed as re-repairs is linked to update the repair information.

[0039] Since the first five digits of the part number representing the component are the same in Repair 2 and Repair 3, Repair 3 is determined to be a re-repair of Repair 2, and 1000 points are calculated as the score value. Since the first digit of the part number representing the component and the first digit of the part number of the replaced component are not the same in Repair 2 and Repair 4, Repair 4 is determined not to be a re-repair of Repair 2. In this case, information that a re-repair was performed is added to the repair information of Repair 2, and the repair information of Repair 3, which was performed as a re-repair, is linked to update the repair information.

[0040] In Repair 3 and Repair 4, the first digit of the part number representing the component and the first digit of the part number of the replaced component are not consistent, so it is determined that Repair 4 is not a re-repair of Repair 3.

[0041] When determining that a plurality of repairs performed at the first time point are repairs corresponding to a single repair performed at the second time point, the re-repair determination unit 12 determines a combination of the repair at the first time point and the repair at the second time point that is most likely to be a re-repair. Figure 6 In the example of , the combination of repair 1b and repair 2, the combination of repair 1b and repair 3, and the combination of repair 1b and repair 4, which are determined to be re-repairs, is determined to be the combination with the highest probability of being a re-repair. In this case, the information that repairs 2 and 3 are most likely to be re-repairs corresponding to repair 1b is added to the repair information of repair 1b, and the repair information is updated. Alternatively, only the combination of repair 1b and repairs 2 and 3 with the highest score is determined to be a re-repair combination.

[0042] Such a score value not only indicates the possibility that the repair at the first time point is a re-repair, but also indicates the magnitude of the impact of the defect related to the re-repair on the product and the priority level of the defect. That is, at the first time point and the second time point, the first five digits of the part number representing the component and the replacement part are the same, and the same part is re-repaired, the probability of the product (part) itself having a quality problem is high, and the part needs to be changed as soon as possible. In this way, when the defect related to the re-repair has a large impact on the product and the priority level of the defect is high, a relatively high score value is calculated. On the other hand, at the first time point and the second time point, the part number representing the component and the replacement part is the same only in the first digit, and different parts are re-repaired, the possibility that the part to be handled was not correctly determined in the initial repair is high, and the possibility of the part itself having a quality problem is low. In this way, when the defect related to the re-repair has a relatively small impact on the product and the priority level of the defect is relatively low, a relatively low score value is calculated.

[0043] The information output unit 13 outputs the repair information stored in the information storage unit 14 and updated to the outside. For example, the updated repair information of each shop that repairs a product such as a vehicle is sent to the information input terminal 20 of each shop. The information output unit 13 may output all the repair information stored in the information storage unit 14, or extract a part of it and output it. For example, only the repair information of each shop may be extracted and sent to the information input terminal 20 of each shop. The output of the updated repair information by the information output unit 13 may be performed every time the information acquisition unit 11 acquires new repair information, or may be performed regularly (for example, every day, every week, every month, etc.). For example, every time the repair information of a new repair is sent from each shop to the device 10, a re-repair determination is performed, and the updated repair information is sent to the information input terminal 20 of each shop. In this case, each shop can quickly confirm whether the new repair is a re-repair to eliminate the defect that was not eliminated by the previous repair, and whether the previous repair has reached the re-repair. As a result, each shop can quickly verify the main reason for reaching the re-repair and take necessary countermeasures.

[0044] Figure 7 1 is a flowchart showing an example of processing executed by the device 10 , and shows an example of a case where a re-repair determination is performed every time new repair information is acquired from the information input terminal 20 . Figure 7 The processing is repeated at a specified cycle. Figure 7 As shown, first, in S1 (S: processing step), it is determined whether new repair information is obtained from the information input terminal 20. When S1 is positive (S1: Yes), the process proceeds to S2, and when S1 is negative (S1: No), the process ends. In S2, the repair information obtained at the first time point in S1 and the repair information with the same vehicle identification number and different cumulative driving distance are extracted from the past repair information stored in the information storage unit 14 as candidates for the repair information at the second time point.

[0045] Next, in S3, it is determined whether the first five digits of the representative part number contained in the repair information at the first time point acquired in S1 and the repair information at the second time point extracted as each candidate in S2 are consistent. If S3 is affirmative (S3: Yes), the process proceeds to S4, where a first score value (1000 points) is assigned to the combination of the repair information at the first time point determined in S3 and the repair information at the second time point, and the repair information stored in the information storage unit 14 is updated.

[0046] When S3 is negative (S3: No), the process proceeds to S5 to determine whether the first five digits of the replacement part number included in the repair information at the first time point determined in S3 and the repair information at the second time point are consistent. When S5 is positive (S5: Yes), the process proceeds to S6 to assign a second score value (100 points) to the combination of the repair information at the first time point determined in S3 and S5 and the repair information at the second time point, and update the repair information.

[0047] When S5 is negative (S5: No), the process proceeds to S7 to determine whether the first digit of the representative part number and the first three digits of the symptom code included in the repair information at the first time point determined in S3 and S5 and the repair information at the second time point are consistent. When S7 is positive (S7: Yes), the process proceeds to S8 to assign a third score value (10 points) to the combination of the repair information at the first time point determined in S3, S5, and S7 and the repair information at the second time point, and update the repair information.

[0048] When S7 is negative (S7: No), the process proceeds to S9 to determine whether the first digit of the replacement part number and the first three digits of the symptom code included in the repair information at the first time point determined in S3, S5, and S7 and the repair information at the second time point are consistent. When S9 is positive (S9: Yes), the process proceeds to S10 to assign a fourth score value (1 point) to the combination of the repair information at the first time point determined in S3, S5, S7, and S9 and the repair information at the second time point, and update the repair information.

[0049] When S9 is negative (S9: No), enter S11, assign a score value (0 points) indicating that it is not a re-repair combination to the combination of the repair information at the first time point determined in S3, S5, S7, and S9 and the repair information at the second time point, and update the repair information.

[0050] Next, in S12, it is determined whether the score values ​​have been calculated for all the candidates of the repair information at the second time point extracted in S2. When S12 is negative (S12: No), the process returns to S3 and determines the next candidate. When S12 is positive, the process proceeds to S13, and the updated repair information is sent to the information input terminal 20, and the process ends.

[0051] Thus, by considering Figure 2 , 5 All the examples of re-repair shown are subjected to re-repair determination (S3 to S11), and it is possible to accurately determine whether each repair is a re-repair. In addition, re-repair determination is performed each time new repair information is obtained, and repair information (S1, S13) is provided, thereby enabling rapid verification of the main cause of re-repair and taking necessary countermeasures.

[0052] The above-described embodiment has the following effects.

[0053] (1) The device 10 comprises: an information storage unit 14 for storing repair information related to the repair of a product; an information acquisition unit 11 for acquiring the repair information; and a re-repair determination unit 12 for determining, based on the repair information acquired by the information acquisition unit 11, whether the repair performed on the product at a first time point is a re-repair for eliminating a defect of the product that was not eliminated by the repair performed at a second time point before the first time point. Figure 3 The repair information includes information about each repair of the product, the occurrence of product defects and the information about the repaired parts ( Figure 7 ).

[0054] The re-repair determination unit 12 determines that the repair performed at the first time point is a re-repair when the first time point target component, which is the target of the repair performed at the first time point, is the same as the second time point target component, which is the target of the repair performed at the second time point, or when the defect content determined based on the defect generation information for the first time point target component is the same as the defect content determined based on the defect generation information for the second time point target component. Figure 2 , 5 ). Thus, consider Figure 2 , 5 All the examples of re-repair shown are subjected to re-repair determination based on the repair information, thereby being able to accurately determine whether each repair is a re-repair.

[0055] (2) When the defect content determined based on the defect occurrence information for the target component at the first time point is consistent with the defect content determined based on the defect occurrence information for the target component at the second time point, the re-repair determination unit 12 determines that the repair performed at the first time point is a re-repair, using the condition that the mounting position of the target component at the first time point on the product is consistent with the mounting position of the target component at the second time point. In this way, it is possible to more accurately determine whether each repair is a re-repair.

[0056] (3) The re-repair determination unit 12 further calculates a score value indicating the probability that the repair performed at the first time point is a re-repair. In the case where the defect content determined based on the defect occurrence information for the target component at the first time point is consistent with the defect content determined based on the defect occurrence information for the target component at the second time point ( Figure 2 The repair determination unit 12 determines the score value of the instance A and C of the repair determination unit 12 when the target component at the first time point is consistent with the target component at the second time point. Figure 2 The score value of the instance A, B) is calculated to be higher ( Figure 5In this case, the possibility that each repair is a re-repair can be simply and accurately evaluated based on the repair information. In addition, the magnitude of the impact of the defect associated with the re-repair on the product and the priority of the response to the defect can be simply and accurately evaluated.

[0057] (4) When the re-repair determination unit 12 determines that a plurality of repairs performed at the first time point are re-repairs corresponding to a single repair performed at the second time point, it determines the combination of the repair performed at the first time point and the repair performed at the second time point that is most likely. In this case, for example, only the combination with the highest score value is determined as the re-repair combination. In addition, since the probability of a quality problem occurring in the product (component) itself is high and the component needs to be promptly responded to by a design change or the like, by determining such a re-repair, necessary responses can be effectively taken.

[0058] (5) The period from the second time point to the first time point is within the prescribed period. Figure 2 , 5 In the case of the example, repairs after a prescribed period of time from the last repair are generally not considered as re-repairs, so whether each repair is a re-repair can be more accurately determined by excluding combinations of repairs that exceed the prescribed period of time.

[0059] In the above embodiment, an example of re-repair determination is described for repair of a product such as a vehicle, but the product is not limited to vehicles. The product may be in any form as long as the content of the defective symptoms in each repair and the information of the parts to be handled are managed as repair information. The product may also be a vehicle, other mobile body, or an engine or motor mounted on a generator.

[0060] In the above embodiment, the device 10 has an information output unit 13, and sends repair information to the information input terminal 20 of a shop that repairs the product, but the repair information providing device is not limited to this. For example, it is also possible to be a device that only automatically performs re-repair determination and updates repair information, and outputs updated repair information according to an output instruction from the outside. In other words, the person who receives the repair information can access the device 10 as needed to obtain the updated repair information.

[0061] In the above embodiment, Figure 7 , etc., it is described that the re-repair determination is automatically performed each time new repair information is obtained, but the re-repair determination unit that performs the re-repair determination is not limited to this. For example, it is also possible to be a device that extracts the repair information of a series of repairs performed on each product from the repair information stored and accumulated in the information storage unit 14 according to an instruction from the outside and performs the re-repair determination. That is, the re-repair determination may also be performed according to the request of the person who receives the repair information.

[0062] The present invention has been described above as a repair information providing device, but the present invention can also be used as a repair information providing method. That is, the repair information providing method includes the following steps executed by a computer: an information acquisition step S1, in which repair information related to the repair of the product is acquired; and re-repair determination steps S2 to S12, in which, based on the repair information acquired in the information acquisition step S1, it is determined whether the repair performed on the product at the first time point is a re-repair to eliminate the defect of the product that was not eliminated by the repair performed at the second time point before the first time point ( Figure 6 The repair information includes information about each repair of the product, the occurrence of product defects and the information about the repaired parts ( Figure 7 In the re-repair determination step, when the object of the repair performed at the first time point, i.e., the first time point object component, is identical to the object of the repair performed at the second time point, i.e., the second time point object component, or when the defect content determined based on the defect generation information for the first time point object component is identical to the defect content determined based on the defect generation information for the second time point object component, it is determined that the repair performed at the first time point is re-repair ( Figure 2 , 5 ).

[0063] One or more of the above-described embodiments and modifications may be arbitrarily combined, and modifications may be combined with each other.

[0064] According to the present invention, it is possible to accurately determine whether each repair is a re-repair.

[0065] The present invention has been described above in conjunction with preferred embodiments, but it should be understood by those skilled in the art that various modifications and changes can be made without departing from the scope of the claims.
