Abstract

According to the present invention, a search request processing unit (108) receives a search request in which any production base among a plurality of production bases is designated as a search production base. A search unit (109) extracts, as a similar production base, another production base similar to the search production base in the configuration of a production process, and searches case information in which a case occurring in the similar production base is shown as similar base case information. The search request processing unit (108) transmits the similar base case information acquired by the search unit (109) to a transmission source of the search request.

Description

Information processing equipment, information processing methods and information processing programs

The present invention relates to a technique for sharing information.

In order to improve the production efficiency of the manufacturing industry, it is important to have a mechanism for sharing information on improvement activities between production bases (for example, factories) or between production processes. For example, it is assumed that the productivity is improved by working on the improvement in the production process X of the production base A. If the production base B also has the production process X, the productivity of the production process X of the production base B can be improved by applying the improvement method in the production process X of the production base A to the production process X of the production base B. Probability is high.
If improvement cases can be shared efficiently throughout the company, the production efficiency of the entire company can be greatly improved. Moreover, if information is shared not only in improvement cases but also in defect cases, the production efficiency of the entire company can be greatly improved. For example, a defect that occurs in the production process Y of the production base A may also occur in the production process Y of the production base B. If the information on the defect that occurred in the production process Y of the production base A can be immediately shared with the production base B, it is possible to prevent the same defect from occurring in the production process Y of the production base B.
In this way, it is very important for the manufacturing industry to share information on improvement cases or failure cases between production bases.

As a matter of course, companies are making various efforts to share improvement cases or failure cases. For example, a method of developing a report on an improvement case or a defect case by e-mail, sharing the improvement case or the defect case on a Web server, or disseminating the improvement case or the defect case at a meeting or the like is taken.
The more information you collect, the more valuable the information becomes, but on the other hand, the more information you collect, the more time and effort it takes to search. Furthermore, there is a dilemma that the person in charge does not see the mail because there are too many emails, and it becomes difficult for the person in charge to receive information on improvement cases or failure cases.
In fact, in a large-scale production base, vertical division for each production process is remarkable, and there are many cases where the person in charge does not recognize the improvement case of the adjacent production process.
Therefore, there is a need for a mechanism for streamlining the search or sharing of improvement case information or defect case information related to the production process.

Patent Document 1 describes a method of collecting and managing defect information for each semiconductor manufacturing apparatus in a semiconductor manufacturing process.
In Patent Document 1, the device code of the semiconductor manufacturing apparatus and the defect information are associated and managed in a database. Then, the defect information is notified to the production process in which the semiconductor manufacturing apparatus having the same apparatus code is installed. As a result, in Patent Document 1, defect information of the semiconductor manufacturing apparatus can be efficiently shared. Further, in Patent Document 1, the improvement case information can be efficiently shared by distributing the improvement case information in the same manner.

Japanese Unexamined Patent Publication No. 2003-108219

However, the method of Patent Document 1 has a problem that only improvement case information or defect case information of the production base where the same device is installed is shared.
For example, it is assumed that the same equipment is not installed in the production base P and the production base Q, but the configurations of the production process of the production base P and the production process of the production base Q are similar. In this case, sharing the improvement case information or the defect case information of the production base P with the production base Q is useful for improving the productivity of the production base Q. However, in the method of Patent Document 1, since the same device is not installed in the production base P and the production base Q, the improvement case information or the defect case information of the production base P is not shared in the production base Q.

The main object of the present invention is to solve such a problem. More specifically, it is a main object of the present invention to obtain a configuration capable of sharing case information of other production bases having a similar configuration of a production process.

The information processing device according to the present invention is
A search request receiving unit that receives a search request in which one of a plurality of production bases is designated as a search production base.
A search unit that extracts other production bases that are similar to the search production base in the configuration of the production process as similar production bases and searches for case information showing cases that occurred at the similar production bases as similar base case information.
It has a search response transmission unit that transmits the similar base case information acquired by the search unit to the source of the search request.

According to the present invention, case information of other production bases having similar production process configurations can be shared.

It schematically represents the state in which it is being used.
Further, the production base information storage unit 103, the similarity table storage unit 105, and the case information storage unit 107 are realized by the main storage device 902 or the auxiliary storage device 903.

Next, a functional configuration example of the information processing apparatus 100 will be described with reference to FIG.

The production base information acquisition unit 101 acquires production base information from the user terminal device 200. Further, the production base information acquisition unit 101 outputs the acquired production base information to the production base information storage unit 102.

The production base information is composed of production process information and production status information.
The production process information describes the composition of the production process of the production base. In the production process information, for example, attributes of the production process such as a factory name, a production process name, and a worker name are described. In the production status information, values generated according to production such as the number of production, the number of non-defective products, and power consumption are described. In the production status information, the current value, the past value, the statistical value (average value) for a certain period, etc. are retained. In the present embodiment, the factory will be described as an example of the production base. The production base is not limited to a factory as long as it is a base where tangible or intangible products are produced. For example, workshops, workshops, software houses, system integrators, design offices, etc. are also included in the production bases.

2 and 3 show an example of production base information.
FIG. 2 shows information on production bases of a company's automobile factory. FIG. 3 shows information on production bases of motorcycle factories of the same company.
The production process of the automobile factory shown in FIG. 2 is composed of an engine assembly process and a motor assembly process. Further, the motor assembly process includes a magnetizing process, a bearing insertion process, a stator assembly process, a rotor assembly process, and an inspection process. The voltage is monitored in the magnetizing process. The voltage is also monitored in the stator assembly process. The amount of magnetic flux is monitored in the rotor assembly process. In the inspection process, inspection values and quality loss values are monitored.
In the example of FIG. 2, the four-wheel factory, engine assembly process, motor assembly process, magnetizing process, bearing insertion process, stator assembly process, rotor assembly process, inspection process, and their connection relationships correspond to production process information. .. Further, in the example of FIG. 2, the voltage, the amount of magnetic flux, the inspection value, and the quality loss correspond to the production status information. For example, by clicking the inspection value with a mouse on the user terminal device 200, the current inspection value, the past inspection value, the statistical value (average value) of the inspection value for a certain period, and the like can be displayed.
The motorcycle production plant shown in FIG. 3 has a similar production process structure, but does not have a magnetizing process and a bearing insertion process.
2 and 3 exemplify the production base information, and do not accurately represent the actual production processes of the four-wheeled factory and the two-wheeled factory. Further, in FIGS. 2 and 3, some steps are omitted for the sake of simplicity of explanation.

The production base information storage unit 102 stores the production base information in the production base information storage unit 103.
Further, the production base information storage unit 102 outputs the production base information to the similarity calculation unit 104.

The production base information storage unit 103 accumulates production base information.

The similarity calculation unit 104 calculates the similarity in the configuration of the production process between a plurality of production bases by using the production base information.
The similarity calculation unit 104 regards the production base information as a graph structure, and calculates the similarity between the graph structures as the similarity in the configuration of the production process between the plurality of production bases. The similarity calculation unit 104 calculates the similarity between graph structures by, for example, a method such as a tree editing distance. For example, if the similarity between the production base A, the production base B, and the production base C has already been calculated and the production base information of the production base D is newly acquired, the similarity calculation unit 104 may perform the similarity calculation unit 104. The degree of similarity is calculated between the production base D and the production bases A to C.
The similarity calculation unit 104 generates a similarity table showing the calculation result of the similarity. Then, the similarity calculation unit 104 stores the similarity table in the similarity table storage unit 105.

FIG. 5 shows an example of a similarity table showing the similarity between production bases A to D. In FIG. 5, the larger the value, the higher the similarity.
In addition, the similarity calculation unit 104 may calculate the similarity using a genetic algorithm, a clustering method, machine learning, or the like. Further, the similarity calculation unit 104 may calculate the similarity by combining these methods.

The similarity table storage unit 105 stores the similarity table generated by the similarity calculation unit 104.

The case information acquisition unit 106 acquires case information from the user terminal device 200. Further, the case information acquisition unit 106 stores the acquired case information in the case information storage unit 107.
The case information includes improvement case information and defect case information.
The improvement case information shows the improvement cases that occurred at the production base. The defect case information shows the defect cases that occurred at the production base.
Case information consists of a structured format and natural language.

FIG. 4 shows an example of improvement case information, which is one of the case information.
The improvement case information has a format composed of items of production base, production process, measures and effects.
The improvement case information describes which production process at which production base the improvement was made. In addition, the improvement case information describes what kind of measures were taken and what kind of effect was obtained. Each item is written in natural language. In addition, in terms included in the production base information, a link with the production base information is set. In FIG. 4, the terms included in the production base information are underlined. Specific values can be referred to by clicking the mouse on the terms included in the production status information of the production base information. Specifically, specific values of "voltage", "magnetic flux amount", "inspection value", and "effect" included in "measures" can be referred to.
As will be described later, the search response to the search request includes improvement case information. When the search response includes the improvement case information of FIG. 4, the "voltage", "magnetic flux amount", "inspection value" and "effect" included in the "measure" in the user terminal device 200 include "quality loss". Each specific value can be referred to by clicking with the mouse. For example, if the "inspection value" included in the "measure" is clicked with the mouse, the time series data of the inspection value is displayed on the user terminal device 200, and the user can know how the inspection value has changed. ..
In the present embodiment, the explanation is advanced using the improvement case information as an example of the case information, but the defect case information basically has the same configuration as the improvement case information of FIG.

The case information storage unit 107 stores case information.

The search request processing unit 108 receives the search request from the user terminal device 200. Further, the search request processing unit 108 transmits a search response, which is a response to the search request, to the user terminal device 200.

In the search request, one of the production bases is designated as the search production base.
In addition, the search response includes production base information of similar production bases and case information of similar bases.
Similar production bases are other production bases that are similar in the process of the search production base and the production process. Further, the similar base case information is case information in which a case occurring at a similar production base is described.
FIG. 12 shows an example of a search response. In the example of FIG. 12, the motorcycle factory is the search production base. Further, in the example of FIG. 12, a four-wheel factory and an air conditioner factory are searched as similar production bases. Then, in the example of FIG. 12, the production base information of the four-wheeled factory is shown, and the improvement case information of the four-wheeled factory is shown as the similar base case information. In FIG. 12, the production base information of the automobile factory is different from that in FIG. 2 due to drawing reasons. Further, in FIG. 12, the production base information of the air conditioner factory and the case information of similar bases are not shown for the reason of drawing, but in reality, the production base information of the air conditioner factory and the case information of similar bases are also included. ..
The search request processing unit 108 corresponds to a search request receiving unit and a search response transmitting unit. Further, the processing performed by the search request processing unit 108 corresponds to the search request reception processing and the search response transmission processing.

The search unit 109 extracts another production base that is similar in the configuration of the production process to the search production base specified in the search request as a similar production base. The search unit 109 refers to the similarity table stored in the similarity table storage unit 105 and extracts similar production bases.
Further, the search unit 109 acquires the production base information of similar production bases from the production base information storage unit 103. Further, the search unit 109 searches for similar base case information in the case information storage unit 107. As described above, the similar base case information is case information that describes a case that occurred at a similar production base.
The search unit 109 generates the search response illustrated in FIG. 12 by using the acquired production base information of the similar production base and the similar base case information.
When the search unit 109 extracts two or more similar production bases and acquires similar base case information of two or more similar production bases, it is based on the degree of similarity with the search production bases of two or more similar production bases. 2. Set a priority between similar base case information of two or more similarity production bases. In the example of FIG. 8, since the automobile factory has a higher degree of similarity to the motorcycle factory than the air conditioner factory, the search unit 109 gives priority so that the improvement case information of the automobile factory is displayed with priority. To set.
The process performed by the search unit 109 corresponds to the search process.

*** Explanation of operation ***
First, the generation of production base information by the user will be described.

In the user terminal device 200, the production base information generation screen illustrated in FIG. 6 is displayed. The user operates the production base information component on the production base information generation screen to generate graph-structured production base information.
When the user clicks the production process part button 211 with the mouse or the like, a list of parts of the production process information is displayed. In the example of FIG. 6, parts of production process information such as "engine assembly process", "motor assembly process", and "magnetization process" are displayed in a pop-up manner, for example. The user can generate production process information by dragging and dropping any of the parts.
Similarly, when the user clicks the production status part button 212 with the mouse or the like, a list of parts of the production status information is displayed. In the example of FIG. 6, parts of production status information such as "voltage", "magnetic flux amount", "inspection", and "quality loss" are popped up, for example. The user can generate production status information by dragging and dropping any of the parts.
When the user clicks the other parts button 213 with the mouse or the like, a list of parts having information other than the production process information and the production status transfer information is displayed. Other information can be generated by dragging and dropping any part.
The user terminal device 200 transmits the generated production base information to the information processing device 100. For example, the user terminal device 200 transmits the production base information illustrated in FIG. 2 or FIG. 3 to the information processing device 100.

Next, with reference to FIG. 7, the production base information storage process and the similarity calculation process by the information processing apparatus 100 will be described.

First, the production base information acquisition unit 101 receives the production base information transmitted from the user terminal device 200 (step S101).
Then, the production base information acquisition unit 101 outputs the production base information to the production base information storage unit 102, and the production base information storage unit 102 stores the production base information in the production base information storage unit 103 (step S102). Further, the production base information storage unit 102 outputs the production base information to the similarity calculation unit 104.

Next, the similarity calculation unit 104 handles the production process information of the production base information as a graph structure, and calculates the similarity in the configuration of the production process between the production bases (step S103).
For example, the similarity calculation unit 104 calculates the similarity between the composition of the production process of the four-wheeled factory and the composition of the production process of the two-wheeled factory by a method such as a tree editing distance.
Then, the similarity calculation unit 104 generates a similarity table in which the similarity between production bases is described, and stores the generated similarity table in the similarity table storage unit 105 (step S104).

FIG. 8 shows an example of a similarity table.
In the similarity table of FIG. 8, the similarity between the air conditioner factory, the chemical factory, the automobile factory, and the motorcycle factory is described. In FIG. 8, the larger the value, the higher the similarity.

Next, the generation of case information by the user will be described. In the following, the generation of improvement case information will be described.

In the user terminal device 200, the improvement case information generation screen illustrated in FIG. 9 is displayed.
The user specifies the production base of the target for which the improvement case information is generated in the production base name designation field 221, and the production base information 222 of the corresponding production base is displayed. The user refers to the production base information 222 and inputs the details of the improvement case in the improvement case information input field 223.
In FIG. 9, improvement case information of the automobile factory is generated.
By clicking each element of the production base information 222 ("four-wheel factory", "motor assembly process", etc.) with the mouse, each element ("four-wheel factory", "motor assembly process"" can be displayed in the improvement case information input field 223. Etc.) are automatically described.
Then, the user terminal device 200 transmits the generated improvement case information to the information processing device 100. Specifically, the user terminal device 200 transmits the improvement case information illustrated in FIG. 4 to the information processing device 100.
In FIG. 9, the production base information 222 is different from that shown in FIG. 2 due to drawing reasons.

Next, the case information storage process by the information processing apparatus 100 will be described with reference to FIG.

First, the case information acquisition unit 106 receives the case information transmitted from the user terminal device 200 (step S201).
Next, the case information acquisition unit 106 stores the case information in the case information storage unit 107 (step S202).

Next, the search request reception process, the search process, and the search response transmission process by the information processing apparatus 100 will be described with reference to FIG.

The search request processing unit 108 receives the search request transmitted from the user terminal device 200 (step S301).

Next, the search request processing unit 108 analyzes the search request and identifies the search production base (step S302). Then, the search request processing unit 108 notifies the search unit 109 of the specified search production base.

Next, the search unit 109 reads the similarity table from the similarity table storage unit 105 (step S303).

Next, the search unit 109 extracts similar production bases according to the similarity shown in the similarity table (step S304).
When there is a limit to the number of similar production bases that include case information in the search response, the search unit 109 extracts the production bases having the highest degree of similarity within the limited number as similar production bases in order. For example, if a company has 10 factories and the number of factories that can include case information in the search response is 5, the search unit 109 has 5 factories in descending order of similarity to the search production base. Extract the factory as a similar production base.
Alternatively, the search unit 109 may extract only factories having a similarity equal to or higher than the threshold value as similar production bases.
If there is no limit to the number of similar production bases that include case information in the search response, the search unit 109 extracts all factories as similar production bases.

Next, the search unit 109 reads the similar base case information, which is the case information of the similarity production base, from the case information storage unit 107 (step S305).

Next, the search unit 109 determines the priority among similar base case information according to the degree of similarity (step S306). Specifically, the search unit 109 sets a high priority for similar base case information of similar production bases having a high degree of similarity.

Next, the search unit 109 generates a search response in which similar base case information is displayed in the order of priority, and outputs the generated search response to the search request processing unit 108.
Then, the search request processing unit 108 transmits the search response to the user terminal device 200 (step S307).
As a result, the search response is displayed on the user terminal device 200, and the user can refer to the similar site case information.

The flow shown in FIG. 11 will be described with reference to a specific example.

In step S301, it is assumed that the search request processing unit 108 receives the search request in which the motorcycle factory is designated as the search production base. That is, the user is requesting a search for case information of a production base having a similar production process configuration to that of a motorcycle factory.

Next, in step S302, the search request processing unit 108 identifies the motorcycle factory as the search production base, and notifies the search unit 109 that the search production base is the motorcycle factory.

Next, in step S303, the search unit 109 reads the similarity table illustrated in FIG. 8 from the similarity table storage unit 105.

Next, in step S304, the search unit 109 extracts similar production bases from the air conditioner factory, the chemical factory, and the automobile factory from the similarity table of FIG.
Here, it is assumed that the number of similar production bases that include case information in the search response is two. In this case, the search unit 109 extracts the four-wheel factory and the air conditioner factory as similar production bases in descending order of similarity with the two-wheel factory.

Next, in step S305, the search unit 109 reads out the case information of the automobile factory and the case information of the air conditioner factory from the case information storage unit 107.

Next, in step S306, the search unit 109 determines the priority order between the case information of the automobile factory and the case information of the air conditioner factory. Since the degree of similarity with the two-wheeled factory is higher in the four-wheeled factory, the search unit 109 sets the priority of the case information of the four-wheeled factory to be high.

Next, in step S307, the search unit 109 generates a search response in which the case information of the automobile factory is displayed first, and the search request processing unit 108 transmits the search response to the user terminal device 200.
For example, the search unit 109 generates the search response shown in FIG.

In the above, an example in which the search unit 109 searches for case information of similar production bases regardless of the type of case has been described. Instead, the search unit 109 may search only the case information indicating a specific type of case.
In this case, the user can specify the type of case in the search request.
For example, the user can specify an improvement case or a defect case as the type of case. When the improvement case is specified as the type of the case in the search request, the search unit 109 searches only the improvement case information of the similar production base as the similar base case information. Similarly, when a defect case is specified as the case type in the search request, the search unit 109 searches only the defect case information of the similar production base as the similar base case information.
The user can also specify the type of case in the form of an improvement case accompanied by improvement of quality loss. When an improvement case accompanied by improvement of quality loss is specified as the case type in the search request, the search unit 109 searches only the improvement case information indicating the improvement of the quality loss of the similar production base as the similar base case information. To do.

Further, the above is an example of the search by the search unit 109, and the search unit 109 can extract related information from any item of each element of the production base information, the graph structure, the improvement case information, and the defect case information. ..
For example, the search unit 109 can extract improvement case information / defect case information of similar production bases by using a part of elements of a certain production process information as a keyword.
Further, the search unit 109 can extract, for example, improvement case information / defect case information of a production process similar to the production process referred to by the improvement case information / defect case information.
Further, the search unit 109 can extract, for example, improvement case information / defect case information of the production process around the production process referred to by the improvement case information / defect case information.
Further, the search unit 109 can extract, for example, the details of the production status information (value of quality loss, etc.) referred to by the improvement case information / defect case information.
Further, the search unit 109 can extract, for example, the improvement case information / defect case information of the production process in which the production status information similar to the production status information referred to by the improvement case information / defect case information exists.

*** Explanation of the effect of the embodiment ***
According to the present embodiment, it is possible to share case information of other production bases having similar production process configurations. That is, according to the present embodiment, it is possible to efficiently search for improvement case information or defect case information of other production bases having a similar production process configuration.

*** Modification example ***
In the above, when the search request is received, the search unit 109 extracts similar production bases and searches for similar base case information. Then, the search request processing unit 108 transmits a search response including the production base information of the similar production base and the similar base case information, which is illustrated in FIG. 12, to the user terminal device 200.
Instead of this, the search unit 109 may extract only similar production bases when a search request is received. In this case, the search request processing unit 108 transmits only the production base information of similar production bases to the user terminal device 200. That is, the search request processing unit 108 transmits the information in which the case information is omitted from FIG. 12 to the user terminal device 200.
The user terminal device 200 that has received the production base information of a similar production base transmits a case information transmission request. The case information transmission request is a message requesting the transmission of case information indicating a case that occurred at a similar production base. In the case information transmission request, it is possible to request that case information of all cases occurring at similar production bases be transmitted, or only case information of improvement cases occurring at similar production bases or case information of defect cases is transmitted. Can also be requested. Further, in the case information transmission request, it is possible to request that only the case information of a specific production process be transmitted.
When the case information transmission request is received by the search request processing unit 108, the search unit 109 searches for the case information (similar base case information) instructed by the case information transmission request. Then, the search request processing unit 108 transmits the similar base case information obtained by the search of the search unit 109 to the user terminal device 200. The search request processing unit 108 may transmit only the case information to the user terminal device 200, or, as illustrated in FIG. 12, transfers the production base information of the similar production base and the similar base case information to the user terminal device 200. You may send it.
