Detailed Description

Hereinafter, a problem information management device, a problem information management method, and an information processing device according to embodiments will be described in detail with reference to the drawings.

Embodiment 1.

The problem information management system according to embodiment 1 collects information on a manufacturing site by using a call application installed in a mobile terminal. Further, the problem information management system according to embodiment 1 organizes and stores information so as to be easily analyzed by making the collected information into a database. An operator at the manufacturing site starts a call application to explain the status of the manufacturing site, thereby making a status report by voice. Further, the worker uses the mobile terminal to photograph the status of the manufacturing site, and transmits the obtained image when reporting the status. The problem information management system can reduce the time and effort required for reporting the status of the manufacturing site, compared to the case where handwriting or manual input by an operator is required. The problem information management system can collate and store information for problems at a manufacturing site in a manner that can be easily analyzed by making the collected information into a database.

Fig. 1 is a diagram showing a schematic configuration of a problem information management system 1 according to embodiment 1. The problem information management system 1 manages information for a problem in a manufacturing site of a product. The manufacturing site is, for example, a factory that manufactures the product.

The problem information management system 1 includes a mobile terminal 2 and a management server 3 as a problem information management server. The management server 3 is an information processing apparatus capable of communicating with the mobile terminal 2.

The mobile terminal 2 is a portable information processing terminal having a call function and a shooting function, and is, for example, a smartphone. The mobile terminal 2 may be a mobile communication terminal or a tablet terminal other than a smartphone. A call application is installed in the mobile terminal 2. As the call application, a messenger application that is widespread as a communication tool can be used.

The management server 3 is a Computer system such as a PC (Personal Computer). The management server 3 performs collection and management of information for problems in the manufacturing site, and analysis of the information. The computer system is provided with a problem information management program. The problem information management program is a program for managing information on a problem in a manufacturing site using the management server 3.

When a trouble such as a failure of equipment in the production line 5 of the factory or a failure of a product manufactured by a job on the production line 5 occurs, the worker 4 starts the call application of the mobile terminal 2 and operates the call application access management server 3. The mobile terminal 2 and the management server 3 are connected to each other via wireless communication. As the wireless communication, local 5G communication may be used, for example.

The mobile terminal 2 transmits the problem situation information to the management server 3 according to the operation performed by the worker 4. The worker 4 reports the status of the problem in the manufacturing site to the manager of the manufacturing site by transmitting the problem status information to the management server 3. The problem situation information is information to be transmitted from the mobile terminal 2 to the management server 3 when the situation at the manufacturing site is reported by using the mobile terminal 2, and is information for explaining the situation.

In embodiment 1, the problem situation information includes voice data and image data. If the worker 4 starts a call application and describes the status of the manufacturing site, voice data representing the voice uttered by the worker 4 is transmitted from the mobile terminal 2 to the management server 3. Further, the worker 4 uses the mobile terminal 2 to photograph the status of the manufacturing site and operates the mobile terminal 2, thereby transmitting image data obtained by photographing from the mobile terminal 2 to the management server 3. The mobile terminal 2 may transmit image data to the management server 3 through an image transmission function of the call application. The image data may be any one of still image data and moving image data.

The mobile terminal 2 transmits the problem determination information together with the problem situation information to the management server 3. The problem specifying information is information for specifying a problem reported by the worker 4. Details regarding the issue determination information are described below.

Fig. 2 is a diagram showing a schematic configuration of the problem information management system 1 according to embodiment 1. The mobile terminal 2 starts the call application 6 according to an operation performed by the operator 4. The mobile terminal 2 transmits the problem situation information to the management server 3.

The management server 3 includes an input/output interface unit 11 as an acquisition unit for acquiring problem situation information, a management database 12 as a storage unit for storing the problem situation information, a voice conversion unit 13 as a conversion unit for converting voice data into text data, a character analysis unit 14 as an analysis unit for performing analysis processing of the text data and outputting an analysis result, and an analysis result storage unit 15 as a storage unit for storing the analysis result. The management server 3 also includes a problem specifying information analyzing unit 16 that analyzes the problem specifying information, and a catalog generation managing unit 17.

The management database 12 has a problem information management directory that holds problem situation information. Hereinafter, the problem information management directory is referred to as a management directory 18. The management directory 18 is a directory generated in association with the problem situation information. The catalog generation management unit 17 generates a management catalog 18. Further, the management database 12 holds a problem situation management list 19. The problem situation management list 19 is a list in which the analysis result of the stored problem situation information is associated with the problem specifying information.

The input/output interface unit 11 receives the problem situation information transmitted from the mobile terminal 2. The input/output interface unit 11 receives the problem specifying information transmitted together with the problem situation information. The question specifying information includes a user name of the login call application 6, information of transmission date and time, position information of the mobile terminal 2, and the like.

The problem specifying information analyzing unit 16 analyzes the problem specifying information received by the input/output interface unit 11. The problem specifying information analysis unit 16 acquires an operator name, which is a user name, as information for specifying the operator 4 who reported the problem. The question specifying information analyzing unit 16 acquires information of the transmission date and time as information for specifying the date and time at which the question was reported. The question specifying information analysis unit 16 acquires the position information of the mobile terminal 2 as information for specifying the location where the question has occurred. The question specifying information analyzing unit 16 outputs the question specifying information to the catalog generation managing unit 17.

The problem specifying information analysis unit 16 specifies the production line 5 or the equipment in which the problem has occurred based on the worker name or the positional information of the mobile terminal 2. When specifying the production line 5 based on the worker name, the problem specifying information analyzing unit 16 acquires the production schedule information and specifies the production line 5 in charge of the worker 4 based on the production schedule information and the worker name. The production schedule information is information showing the date and time when a job is performed and the allocation of resources used for the job required for production. The question specifying information analysis unit 16 estimates the location of the occurrence of the question from the position information of the mobile terminal 2. The problem specifying information analyzing unit 16 may specify a product in which a problem has occurred based on the product information when the product information, which is information on a product scheduled to be produced, is included in the production schedule information.

The question specifying information analyzing section 16 may also acquire acceleration information of the mobile terminal 2 from the mobile terminal 2 as the question specifying information. The problem specifying information analysis unit 16 obtains the direction angle of the movement of the mobile terminal 2 based on the acceleration information, and specifies the location where the problem has occurred based on the direction angle of the movement of the mobile terminal 2 and the position information of the mobile terminal 2.

The catalog generation management unit 17 generates a management catalog 18 in the management database 12 if the problem specifying information is received from the problem specifying information analysis unit 16. The catalog generation management unit 17 stores the problem specifying information, that is, information on the name of the worker and the date and time and the position information, in the generated management catalog 18. Specifically, the catalog generation management unit 17 reserves a part of the storage area of the management database 12 as an area for managing the catalog 18, and adds the problem specifying information to the reserved area. The management database 12 stores the problem situation information in a storage area to which the problem determination information is attached.

The catalog generation management unit 17 writes the same problem specifying information as the problem specifying information stored in the management catalog 18 into the problem situation management list 19. In this way, the management server 3 causes the problem specifying information stored in the management directory 18 to be reflected in the problem situation management list 19.

The input/output interface unit 11 stores the generated management directory 18 with the voice data and the image data as the problem situation information. In embodiment 1, the problem status information reported from the operator 4 by using the mobile terminal 2 is not limited to information on problems of the production line 5, equipment, or manufactured products. The problem status information may include information related to the attention of the operator 4 such as difficulty in work or judgment. The problem situation information may be information that can communicate a situation by transmitting voice data or image data, and may be information that can be correlated with improvement of the situation at the manufacturing site.

The status of the problem can be reported by voice or image using the mobile terminal 2 such as a smartphone, and the work performed by the operator 4 to report the status can be simplified. Further, the psychological burden on the report can be reduced. Thus, the problem information management system 1 can easily collect information that can be associated with improvement of the condition of the manufacturing site.

The voice conversion unit 13 converts the voice data stored in the management directory 18 or the voice data acquired from the input/output interface unit 11 into text data. The voice conversion unit 13 converts voice data into text data by combining the voice data with language data. The voice conversion unit 13 has a voice recognition dictionary, and recognizes the voice of the voice data by collating the result of acoustic analysis of the voice data with the voice recognition dictionary. The voice conversion section 13 outputs the text data by changing the recognized voice into text. The illustration of the speech recognition dictionary is omitted. In this manner, the voice conversion unit 13 recognizes a voice shown in the voice data, thereby converting the voice data into text data.

The speech recognition dictionary is composed of an acoustic model, a language model, and a pronunciation dictionary. The speech model is a model for discriminating a character represented by a speech by analyzing a frequency component of the sound or a temporal change of the sound. For example, the acoustic model is obtained by digitizing the characteristics of the sound of each character of "hello". The language model is a model for evaluating whether a character string or a phrase is appropriate as japanese, and performs statistical processing on japanese texts collectively. The pronunciation dictionary is a dictionary for connecting words of the language model and the acoustic model. That is, the speech conversion unit 13 analyzes the speech of the speech data based on the acoustic model, and then constructs a word pronunciation using the pronunciation dictionary. Further, the speech conversion section 13 evaluates the arrangement of the word pronunciation based on the language model. Thus, the voice conversion section 13 realizes high-precision conversion from voice data to text data.

The voice conversion unit 13 outputs the text data to the character analysis unit 14. The character analysis unit 14 performs an analysis process of extracting characters corresponding to a preset management item, which is an item indicating a status of a question, from the text data. The character analysis unit 14 outputs characters as analysis results to the analysis result storage unit 15.

Fig. 3 is a diagram for explaining analysis of text data in the problem information management system 1 according to embodiment 1. Each item of "defect classification", "defect phenomenon", "defect position", and "detailed content" is an example of a preset management item. Fig. 3 shows an example of characters extracted by the character analysis unit 14 when there is a problem of a product such that fastening of screws is loose in several positions of the aligner.

The character analysis unit 14 learns characters corresponding to each management item in advance and extracts the characters from the text data. In fig. 3, for example, "job failure" and "failure classification" correspond to characters. The character analysis unit 14 extracts characters corresponding to the management items from the text data, thereby decomposing the text data into information necessary for managing the problem situation.

The character analysis unit 14 extracts characters related to the management items by performing text mining for each management item. In embodiment 1, the character analysis unit 14 performs text mining by emotion analysis. Without being limited thereto, the character analysis section 14 may also perform text mining by correspondence analysis or principal component analysis.

The analysis result storage unit 15, if acquiring the analysis result from the character analysis unit 14, stores the analysis result in the management database 12 by writing the analysis result in the problem situation management list 19. Thereby, the management server 3 reflects the analysis result in the problem situation management list 19.

Fig. 4 is a diagram showing an example of the problem situation management list 19 held by the problem information management system 1 according to embodiment 1. Each item of "date and time", "reporter", and "problem occurrence place" is an item of problem specifying information. In the question status management list 19, information of the date and time at which the question was reported is written in the "date and time" column. The column "reporter" has the name of the operator written therein. Information indicating the location of the problem is written in the "location of the problem". In the column of "trouble occurrence place", a line name indicating the production line 5 in which a trouble occurred, a part name indicating a part in which a trouble occurred in a product, an equipment name indicating equipment in which a trouble occurred, and the like are written.

Each of the items "failure classification", "failure phenomenon", "failure location", and "detailed content" is a management item. In the problem situation management list 19, the analysis results acquired from the character analysis unit 14 are written in each column of "failure classification", "failure phenomenon", "failure location", and "detailed content".

The "image storage location" indicates a storage location of the management directory 18 in which the image data is stored. An information address indicating a storage location is written in the column of the "image storage location". When creating the management directory 18, the directory creation management unit 17 writes information indicating the storage location into the problem situation management list 19. In this way, the management server 3 reflects information indicating the storage location of the management directory 18 on the problem situation management list 19.

In embodiment 1, the question information management system 1 stores voice data transmitted using the call function of the call application 6 in the management server 3. In the problem information management system 1, the mobile terminal 2 acquires image data by shooting using a shooting function, and stores the image data transmitted from the mobile terminal 2 in the management server 3. The voice data and the image data are stored in the management server 3 by operations different from each other in the mobile terminal 2. Therefore, the problem information management system 1 needs to associate and manage the voice data and the image data with each other.

Fig. 5 is a diagram for explaining a process for managing voice data and image data in association with each other in the problem information management system 1 according to embodiment 1. The mobile terminal 2 transmits voice data and image data to the management server 3 in the first access for status report. The management server 3 stores the problem specifying information obtained by analyzing the data in the initial access in the generated management directory 18.

The management server 3 analyzes the problem specifying information with respect to the voice data or the image data received after the initial access, and stores the received voice data or the image data in the management directory 18 in which the same problem specifying information as the analyzed problem specifying information is added. Thereby, the question information management system 1 associates and manages the voice data and the image data transmitted from the mobile terminal 2 with each other according to the question determination information.

In the above description, the management server 3 generates the management directory 18 at the time of the initial access, but may generate the management directory 18 after the initial access. When the management server 3 generates the management directory 18 after the initial access, the management directory 18 stores therein the voice data and the image data associated with the same information as the question specifying information stored in the management directory 18. In this case, the question information managing system 1 may associate and manage the voice data and the image data with each other.

Fig. 6 is a flowchart showing an operation procedure of the problem information management system 1 according to embodiment 1. In step S1, the input/output interface section 11 acquires the voice data and the image data as the problem situation information, and the problem specifying information. In step S2, the problem specifying information analyzer 16 analyzes the problem specifying information acquired from the input/output interface unit 11. In step S3, the catalog generation management unit 17 generates the management catalog 18 to which the problem specifying information is attached.

In step S4, the management database 12 stores the problem situation information in the generated management directory 18. In step S5, the voice conversion unit 13 converts the voice data stored in the management directory 18 or the voice data acquired from the input/output interface unit 11 into text data. The voice conversion unit 13 outputs the text data to the character analysis unit 14.

In step S6, the character analysis unit 14 performs analysis processing of the text data and outputs the analysis result to the analysis result storage unit 15. In step S7, the analysis result storage unit 15 writes the analysis result in the problem situation management list 19, thereby storing the analysis result in the management database 12. Through the above steps, the problem information management system 1 ends the steps shown in fig. 6.

According to embodiment 1, in the problem information management system 1, the management server 3 can acquire the problem situation information including the voice data, and thus the time and effort for reporting the situation of the manufacturing site can be reduced. Further, the problem information management system 1 needs to convert voice data into text data and perform analysis processing for extracting characters corresponding to management items from the text data. The problem information management system 1 stores the analysis result in the problem situation management list 19. Thus, the problem information management system 1 can manage information on problems in the manufacturing site in an easily analyzable manner.

Further, according to embodiment 1, the burden of status report by the operator 4 is reduced, and thus the number of reports for the status of the manufacturing site is expected to increase. In this way, the problem information management system 1 can acquire a large amount of information regarding the status of the manufacturing site, and can realize a highly accurate analysis of the problem. Further, the problem information management system 1 can facilitate analysis for a problem.

Embodiment 2.

In the problem information management system 1A, the camera 7 captures the status of the manufacturing site, and the camera 7 transmits image data to the management server 3A. The management server 3A is different from the management server 3 shown in fig. 2 in that it has an instruction function for the camera 7. In embodiment 2, the same components as those in embodiment 1 are denoted by the same reference numerals, and the description will be mainly made of a structure different from that in embodiment 1.

The camera 7 is installed in a factory as a manufacturing site at a position where the production line 5 can be photographed. A plurality of cameras 7 may also be provided in the factory. In the following description, the plurality of cameras 7 are provided in the factory so as to be able to photograph all the production lines 5 in the factory. Cameras 7 may also be provided on each production line 5. Each camera 7 has a communication function of transmitting image data to the management server 3A. The image data may be any one of still image data and moving image data.

In embodiment 2, the worker 4 uses the portable terminal 2 to perform a status report by voice as in the case of embodiment 1. Upon receiving the access from the mobile terminal 2, the management server 3A identifies the production line 5 on which the status report is present. The management server 3A specifies an operator 4 who holds the mobile terminal 2 as a sender, specifies a production line 5 for which the operator 4 is responsible, and specifies the production line 5 on which the status report is present. The management server 3A instructs shooting to the camera 7 provided in the determined production line 5. The camera 7 captures images of the production line 5 in response to an instruction from the management server 3A, and transmits image data to the management server 3A. The management server 3A may specify the position of the mobile terminal 2 as the sender and instruct the camera 7 at the position closest to the specified position to perform imaging.

In this manner, the management server 3A acquires voice data and image data as problem situation information. As in embodiment 1, the problem information management system 1A associates and manages voice data transmitted from the mobile terminal 2 and image data transmitted from the camera 7 with each other.

According to embodiment 2, in the problem information management system 1A, even if the worker 4 does not take an image of the manufacturing site, it is possible to acquire image data. Problem information management system 1A can further simplify the work performed by worker 4 to report the situation.

In addition, the photographing by the camera 7 is not limited to the case based on the reception of the instruction from the management server 3A. The camera 7 may also detect access from the mobile terminal 2 to the management server 3 and take the access as a trigger to be shot by the camera 7. The camera 7 may detect access from the mobile terminal 2 to the management server 3 through local communication with the mobile terminal 2.

In embodiment 3, the same components as those in embodiment 1 or 2 are denoted by the same reference numerals, and a description will be given mainly of a configuration different from that in embodiment 1 or 2.

Upon receiving an access from the mobile terminal 2, the management server 3B transmits an inquiry item for each management item to the mobile terminal 2. The query item is information for guiding a status report for the management item. The call application 6, if receiving the information from the management server 3B, causes a voice indicating the content of the received information to be output to the mobile terminal 2. The portable terminal 2 outputs "what is a bad classification? "or" what adverse phenomenon? "speech of such a query.

The management server 3B confirms the status of the management items necessary for the problem management to the worker 4 in the form of an inquiry via the call application 6. This reduces the possibility of missing problem situation information in the problem information management system 1B. The problem information management system 1B can define information for management items and analyze voice data, and therefore, can improve analysis accuracy.

The call application 6 gives a question to the worker 4 in response to an instruction from the management server 3B, and transmits voice data as a response to the question to the management server 3B. The catalog generation management unit 17 shown in fig. 2 stores the data of the question and the voice data as the answer in the management catalog 18 in association with each other. The voice conversion unit 13 shown in fig. 2 acquires voice data from the management directory 18 for each inquiry, and converts the acquired voice data into text data. The character analysis unit 14 shown in fig. 2 performs an analysis process of extracting characters corresponding to the management items from the text data.

In embodiment 3, the management server 3B acquires the voice data corresponding to the query, and thus the voice conversion section 13 and the character analysis section 14 can realize learning to extract the content corresponding to the query for each query.

The analysis result storage section 15, if acquiring the analysis result from the character analysis section 14, transmits the analysis result to the question situation management list 19 and the transmission processing section 20. The transmission processing unit 20 processes the obtained analysis result in order to report the situation to the outside of the problem information management system 1C. For example, the transmission processing unit 20 changes the data format of the analysis result to a format that can be viewed by the management terminal 8. The transmission processing unit 20 processes the analysis result into an expression predetermined for reporting. In this manner, the transmission processing unit 20 generates the problem report information, which is information for reporting the state of the problem, from the result of the processing analysis. The transmission processing unit 20 outputs the problem report information to the input/output interface unit 11. The input/output interface unit 11 transmits the problem report information to the management terminal 8.

The transmission processing unit 20 may add the address of the management directory 18, which is the storage location of the image data, or the address of the management directory 18, which is the storage location of the voice data, to the problem report information. The transmission processing unit 20 may add the image data stored in the management directory 18 to the problem report information.

If the management terminal 8 receives the trouble report information, the management terminal 8 displays the contents of the trouble report information on the display unit of the management terminal 8. The management terminal 8 may output a voice indicating the contents of the problem report information through a voice output unit of the management terminal 8 as necessary. The illustration of the display unit and the voice output unit is omitted. The administrator visually recognizes the display on the display unit or hears a sound from the management terminal 8 to confirm the contents of the question report information.

The management terminal 8 may display the address on the display unit to accept an operation for accessing the management directory 18 when the address of the management directory 18 is added to the trouble report information. By clicking the address, the management terminal 8 reads the image data or the voice data in the management directory 18 from the management database 12. The management terminal 8 reads the image data to display an image on the display unit. The management terminal 8 reads the voice data and outputs the voice from the voice output unit. Thus, the problem information management system 1C can communicate the status of the manufacturing site to the administrator.

Embodiment 5.

Fig. 11 is a diagram showing a schematic configuration of the problem information management system 1D according to embodiment 5. The problem information management system 1D according to embodiment 5 includes the mobile terminal 2, a management server 3D serving as a problem information management server, and an actual production rate management device 9 that manages an actual production rate of the worker 4. In embodiment 5, the same components as those in embodiments 1 to 4 described above are denoted by the same reference numerals, and the description will be mainly given of configurations different from those in embodiments 1 to 4.

The actual yield management apparatus 9 is an apparatus capable of communicating with the management server 3D, and is a computer system such as a PC. The actual yield management device 9 collects the actual yield on the production line 5. The actual yield management apparatus 9 counts the number of non-defective products and the number of defective products. The actual yield management device 9 calculates the actual yield of the worker 4 based on the actual yield based on the number of non-defective products. The actual yield management apparatus 9 manages the actual yield individually for each worker 4 at the manufacturing site.

When a problem occurs in the production line 5, equipment, or a product, the worker 4 reports the problem using the mobile terminal 2. As a result of analyzing the problem situation information transmitted from the mobile terminal 2 by the management server 3D, it is found that the cause of the defective product is a problem of the device or design, that is, a problem not attributable to the worker 4. In this case, the management server 3D notifies the actual yield management apparatus 9 that a defective product is generated because it is not due to a problem of the worker 4, and transmits information indicating the corresponding defective product to the actual yield management apparatus 9. In this manner, the management server 3D transmits the analysis result of the problem situation information to the actual yield management apparatus 9.

Fig. 12 is a diagram for explaining the management of actual yields by the actual yield management device 9 of the problem information management system 1D according to embodiment 5. In fig. 12, "P1" represents the actual yield based on the number of non-defective products. "P2" is set as the actual production amount based on the number of defective products that are generated because of problems that are not attributable to the operator 4. The actual yield management apparatus 9 adds "P1" based on the number of non-defective products and "P2" based on the number of defective products not attributed to the operator 4. The actual yield management apparatus 9 recognizes "P1 + P2" as the actual yield of the operator 4, and manages the actual yield of the operator 4. In this way, the actual yield management apparatus 9 corrects the actual yield of the worker 4 based on the analysis result received from the management server 3D.

The actual yield management device 9 may exclude the actual yield for the reject attributed to the operator 4 from the actual yield of the operator 4 and include the actual yield for the reject not attributed to the operator 4 in the actual yield of the operator 4. When the cause of the defective product is a problem of equipment or design, the actual production volume for the defective product is not excluded from the actual production volume of the worker 4, and therefore the problem information management system 1D can achieve an incentive to improve the situation in which a problem is reported to the worker 4. In the case where a defective product due to the worker 4 is generated, the operator of the plant may be set to omit payment of a reward based on the actual production amount for the defective product.

Embodiment 6.

In embodiment 5, a case where the worker 4 reports a problem that a defective product occurs in the actual yield of the worker is described. That is, in embodiment 5, the operator 4 reports the actual production volume of the operator. Embodiment 6 is different from embodiment 5 in that it has a function of reporting the actual workload of another operator 4 by the operator 4. The problem information management system 1D according to embodiment 6 has the same configuration as the problem information management system 1D according to embodiment 5. In embodiment 6, the operation different from that of embodiment 5 described above will be mainly described.

When reporting the actual work volume of the other worker 4, the worker 4 inputs the name of the other worker 4 to the call application 6 of the mobile terminal 2 as information for specifying the work to be reported, instead of inputting the name of the worker 4 to the call application 6 of the mobile terminal 2. The operator 4 inputs the name of the production line 5 operated by the other operator 4 to the call application 6. The worker 4 inputs the name of the worker as the name of the reporter to the call application 6. The mobile terminal 2 transmits the input information to the management server 3D. Further, as in the case of embodiments 1 to 5 described above, the mobile terminal 2 transmits the problem situation information to the management server 3D. In addition, as in the case of embodiment 2, the management server 3D may acquire image data transmitted by the camera 7.

As a result of analyzing the problem status information transmitted from the mobile terminal 2 by the management server 3D, it is found that the cause of the defective product is a problem of the equipment or design, that is, a problem not caused by the worker 4. In this case, the management server 3D notifies the actual yield management apparatus 9 that a defective product is generated because it is not due to a problem of the worker 4, and transmits information indicating the corresponding defective product to the actual yield management apparatus 9.

The actual yield management device 9 adds an actual yield based on the number of defective products generated due to a problem not attributed to the worker 4 to the actual yield of the worker 4 as a reporter. Problem information management system 1D can achieve an incentive to improve the situation in which a problem is reported to worker 4 by adding the actual yield based on the number of defective products that are not attributed to worker 4 to the actual yield of the reporter. In addition, the actual yield management apparatus 9 may count the actual yields for the defective products as the actual yields of the reporters based on the information directly transmitted from the mobile terminal 2 to the actual yield management apparatus 9 instead of the information transmitted from the management server 3D.

In embodiment 6, the actual yield management apparatus 9 may add the actual yield based on the number of defective products to the actual yield of the reporter regardless of the cause of defective products. In this case, the problem information management system 1D can also realize an incentive to improve the situation in which the worker 4 reports a problem.

Embodiment 7.

In

embodiments

5 and 6, the case where the actual yield for the defective product is added to the actual yield of the worker 4 is described. In embodiment 7, the actual yield management device 9 multiplies the actual yield for the defective product by a coefficient, and adds the actual yield to the actual yield of the operator 4. The coefficient may be a value greater than 0 and lower than 1, for example 0.5. In this way, the actual yield management device 9 may reduce the actual yield for the defective products to be lower than the actual yield for the non-defective products, and add the actual yield for the defective products to the actual yield of the operator 4.

Embodiment 8.

In embodiment 1, an operator 4 who has found a problem in a production line 5, equipment, or a product accesses the management server 3 using the mobile terminal 2, thereby managing information on the problem. In embodiment 8, when a problem is detected in a manufacturing site, the management server 3 transmits an instruction to investigate the situation of the problem to the mobile terminal 2.

When a problem is detected by a device of the production line 5, the device transmits error information indicating that the problem has occurred to the management server 3. The management server 3 instructs a worker 4 located closest to the device, which is the sender of the error information, or the worker 4 who performs work on the production line 5 including the device to investigate the situation of the problem. The management server 3 transmits a message instructing a survey to the mobile terminal 2 held by the worker 4. As in the case of embodiment 1, the worker 4 having received the instruction transmits the problem situation information to the management server 3.

The management server 3 grasps the current position of each mobile terminal 2 based on information of a GPS (Global Positioning System) function mounted on the mobile terminal 2. The management server 3 can select an optimum mobile terminal 2 from the plurality of mobile terminals 2 and transmit an instruction by grasping the current position of each mobile terminal 2.

In embodiment 8, the problem information management system 1 can reduce the time and effort for reporting the status of the manufacturing site. In the problem

information management systems
