(System configuration)
FIG. 1 is a block diagram showing an example of an operation management system according to each embodiment.
The operation management system 100 has a daily report creation system 10 and a nonconformity management system 20 . The operation management system 100 is a document management system having a function of registering and accumulating information useful for plant operation management and presenting it to operators. For example, the daily report creation system 10 receives input of event information such as various incidents and observations that occurred during plant operation by operators, creates daily report data in plant operation, and a document registration system that stores the daily report data. is. Daily report data is accumulated as a record of plant operating conditions. In addition, there are cases where the plant is operated on a 24-hour basis, and the daily report data is used for taking over when the operator changes. The nonconformance management system 20 is a related document registration system that receives input of nonconformity information related to daily report data and stores the nonconformity information. The non-conformity information includes information (details of progress, countermeasures, etc.) from the occurrence of a trouble that occurred during plant operation to its resolution. Non-compliance information is shared within the company that operates the plant, and is used as a knowledge base for formulating maintenance plans and how to deal with abnormalities. Conventionally, when an operator inputs daily event information into the daily report creation system 10 and nonconformity information is included in the event information (when an abnormality occurs during operation), the nonconformance management system 20 Non-conformance information is entered into the On the other hand, in the operation management system 100 of the present embodiment, when an operator inputs event information to the daily report creation system 10, if the event information includes nonconformity information, the nonconformity management system 20 automatically Provide a function to register the contents.

As illustrated, the daily report creation system 10 has an input unit 11 , a control unit 12 , an output unit 13 , a storage unit 14 and a communication unit 15 .
The input unit 11 is configured using input devices such as a keyboard, mouse, touch panel, and buttons. The input unit 11 receives input from the user's operation on the daily report creation system 10 . The input unit 11 outputs the content of the received input to the control unit 12 .
The control unit 12 controls the daily report input process and the process of registering the nonconforming information in the nonconforming management system 20 when the daily report data contains nonconforming information. For example, the control unit 12 creates a daily report registration screen for inputting daily report data, displays it on the display device, and registers the daily report data input to the daily report registration screen in the storage unit 14 . The control section 12 also has a document processing section 121 . The document processing unit 121 has natural language processing functions such as morphological analysis, syntactic analysis, semantic analysis, and contextual analysis. The document processing unit 121 uses a natural language processing function to detect non-conforming information from the input daily report data, and executes processing for registering the detected non-conforming information in the non-conforming management system 20 (first embodiment).

The output unit 13 outputs a daily report registration screen and the like to the display device.
The storage unit 14 stores various information such as input daily report data and various dictionaries.
The communication unit 15 communicates with the nonconforming management system 20 to transmit and receive data.

The nonconforming management system 20 includes an input unit 21 , a control unit 22 , an output unit 23 , a storage unit 24 and a communication unit 25 .
The input unit 21 is configured using input devices such as a keyboard, mouse, touch panel, and buttons. The input unit 21 receives an input by a user's operation to the nonconforming management system 20 . The input unit 21 outputs the content of the received input to the control unit 22 .
The control unit 22 controls registration processing and editing processing of nonconforming information. For example, the control unit 22 creates a nonconforming information processing screen, displays it on the display device, and registers the nonconforming information input on the screen in the storage unit 24 . The control unit 22 has various functions for supporting registration and editing of nonconforming information (second to fourth embodiments). For example, the control unit 22 has natural language processing functions such as morphological analysis, syntactic analysis, semantic analysis, and contextual analysis. The control unit 22 uses the natural language processing function to analyze the registered non-conforming information, classify the non-conforming information (event classification, equipment classification, system classification), and search for other similar non-conforming information ( third and fourth embodiments). The control unit 22 also receives a nonconformity information registration notification from the daily report creation system 10, and notifies the daily report creation system 10 of link information for accessing the nonconformity information (first embodiment).
The output unit 23 outputs the nonconforming information processing screen and the like to the display device.
The storage unit 24 stores various information such as nonconformity information. For example, the storage unit 24 stores a nonconforming information database 241 and various dictionaries. Nonconforming information is registered and accumulated in the nonconforming information database 241 .
The communication unit 25 communicates with the daily report creation system 10 to transmit and receive data.

<First Embodiment>
Next, automatic registration processing of nonconforming information will be described as a first embodiment with reference to FIGS. 2 to 5. FIG. FIG. 2 shows an outline of processing by the document processing unit 121. As shown in FIG. An operator of the plant registers daily report data as illustrated in the frame 2A of FIG. The document processing unit 121 uses syntactic analysis, morphological analysis, etc. to segment the daily report data into words (terms), and refers to dictionaries, databases, etc. in which terms appearing in nonconforming information are described (these dictionaries, databases, etc.). are registered in the storage unit 14.), and the nonconforming information (the underlined portion of the frame 2A) included in the daily report data is detected. In addition, when the document processing unit 121 detects a term that serves as a marker for nonconforming information in the daily report data, the document processing unit 121 identifies the abnormalities, etc. identify the category of For example, in the case of the nonconformance information shown in frame 2A, the document processing unit 121 converts the underlined sentences from words such as conveyor, abnormal noise, and stop to abnormality (abnormality 2B) related to the conveyor and boiler, water quality, deterioration, etc. The word is analyzed to include nonconformance information of different categories of boiler-related abnormality (abnormality 2C), and the two pieces of analyzed nonconformity information are registered in the nonconformity information database 241 as two pieces of data. Conventionally, when registering (drafting) nonconformance information for two cases, an operator had to input nonconformance information twice through the nonconformity information processing screen in addition to inputting daily report data. According to the operation management system 100 , just by inputting daily report data into the daily report creation system 10 , the document processing section 121 can automatically register two cases of nonconformity information in the nonconformity management system 20 .

(Automatic registration processing of non-conforming information)
Next, with reference to FIGS. 3 to 5, automatic registration processing of nonconforming information according to the first embodiment will be described in detail. FIG. 3 is a flowchart showing an example of automatic registration processing of nonconforming information according to the first embodiment.
First, an operator inputs daily report data into the daily report creation system 10 (step S1). The daily report data includes a daily report ID, a date, an input person, the content of the event that occurred (event information), and the like. An example of daily report data is shown in FIG. 4A. The input unit 11 acquires the input daily report data and outputs it to the control unit 12 . The control unit 12 records the daily report data in the storage unit 14 (step S2), and instructs the document processing unit 121 to detect nonconforming information.

Based on this instruction, the document processing unit 121 starts detection of non-conforming information that satisfies a predetermined condition (search processing for non-conforming sentences). First, the document processing unit 121 divides the daily report data (text data) into sentences (step S3). FIG. 4B shows the result of dividing the daily report data of FIG. 4A into sentence units. The document processing unit 121 performs semantic analysis and contextual analysis to categorize the content of the sentences and divides the sentences into categories. For example, the document processing unit 121 classifies a sentence about a conveyor and a sentence about a boiler into different categories and divides them into different sentences. The document processing unit 121 counts and stores the position of the leading character and the position of the trailing character of each divided sentence. Next, the document processing unit 121 searches each sentence obtained by division for a sentence including nonconforming information (referred to as an incompatible sentence). First, the document processing unit 121 morphologically analyzes the divided text and subdivides the text into term levels (step S4). FIG. 4C shows the result of segmentation into term levels by morphological analysis. Next, the document processing unit 121 performs a process of absorbing term fluctuations for each word obtained by division (step S5). The document processing unit 121 refers to a dictionary (this dictionary is registered in the storage unit 14) in which synonyms, synonyms, etc. are defined for each term, and absorbs variations in spelling of terms. For example, in the dictionary, synonyms of "breaker" such as "breaker", "CB", and "breaker" are registered, and "breaker" is defined as a representative word. The document processing unit 121 unifies these remaining terms after fragmentation into "breakers." Next, the document processing unit 121 identifies nonconforming sentences based on the subdivided terms (step S6). For example, the document processing unit 121 refers to a dictionary or database that defines terms representing anomalies, troubles, etc. and their combinations (for example, a combination of “breaker” and “failure”), and refers to the terms registered in this dictionary. Identifies sentences containing or combinations thereof as nonconforming sentences. The document processing unit 121 determines whether or not each of the sentences divided in step S3 is an incompatible sentence.

Next, the document processing unit 121 determines whether or not there is an inappropriate sentence in the daily report data (step S7). If there is no non-conforming sentence (step S7; No), there is no need to register non-conforming information in the non-conforming management system 20, so the processing flow of FIG. 3 ends.

If there is a non-conforming sentence (step S7; Yes), the document processing unit 121 stores the non-conforming sentence (including multiple), the date, the daily report ID, the person who entered it, the position (number of characters) of the beginning and end of the non-conforming sentence, etc. (step S8). Examples of two nonconforming sentences detected from the daily report data of FIG. 4A are shown in FIGS. 4D and 4E. FIG. 5 shows an example of the nonconformance information database 241 in which two nonconformance sentences are registered (the information in the "nonconformance management chart ID" column and the "nonconformity management table address information" column will be registered in a later process. .). Note that the layout of the nonconforming information database 241 illustrated in FIG. 5 is an example. In addition to the items illustrated in FIG. 5, the nonconformity information database 241 includes items such as "discoverer" item, "severity" item, "event classification code" item, "equipment classification code" item, and "system classification code" item. may have

After completing the registration of the nonconforming sentences in the nonconforming information database 241, the document processing unit 121 next notifies the nonconforming sentence management system 20 of the completion of registration of the nonconforming sentences (step S9). The document processing unit 121 transmits a registration completion notification to the nonconforming management system 20 through the communication unit 15 . In the nonconforming management system 20 , the control section 22 receives the registration completion notification through the communication section 25 . When the registration completion notification is received, processing on the nonconforming management system 20 side is started.

First, the control unit 22 acquires nonconformity sentences from the nonconformity information database and automatically issues a nonconformity processing slip (step S10). For example, the control unit 22 assigns a nonconformance management ID to nonconformity information newly registered in the nonconformity information database 241 and registers the ID in the “nonconformity management slip ID” column of the nonconformity information database 241 . The nonconformance information numbered with the nonconformity management slip ID is called a nonconformity processing slip. Next, the control unit 22 registers the access information (address, shortcut, etc.) to the issued nonconforming processing slip in the nonconforming information database 241 (step S11). For example, the control unit 22 generates access information such as a link to a nonconformance information processing screen (for example, FIG. 7) on which two newly automatically generated nonconformance processing slips can be displayed and edited. , the access information is registered in the "nonconforming management table address information" column of the nonconforming information database 241. FIG. Next, the control unit 22 notifies the daily report creation system 10 of the completion of registration of the access information to the newly issued nonconforming processing slip through the communication unit 25 (step S12). In the daily report creation system 10 , the document processing section 121 receives the access information registration completion notification through the communication section 15 . Upon receiving the registration completion notification, the document processing unit 121 acquires information and access information related to the registered non-conforming text, and embeds the access information in the relevant text (step S13). The document processing unit 121 reads out the daily report data registered in the storage unit 14 in step S2, and records in the storage unit 14 the inappropriate sentences included in the daily report data in association with appropriate access information. For example, the document processing unit 121 associates the nonconformance document regarding the conveyor with the access information for the nonconformance processing form issued regarding the conveyor, and the nonconformance processing section 121 associating the nonconformance processing chart issued regarding the boiler with the nonconformance document regarding the boiler. Access information is associated and recorded. An example of daily report data after embedding access information is shown in FIG. 4F.

(effect)
As described above, according to the present embodiment, when an operator registers daily report data in the daily report creation system 10, it is possible to automatically issue a non-conforming processing slip. As a result, the operator's burden of re-inputting the same non-conforming text as the non-conforming text included in the daily report data into the non-conforming management system 20 is reduced. In addition, by absorbing terminology fluctuations in step S5, it is possible to identify nonconforming sentences with high accuracy. In addition, by deploying the access information to the processing slip automatically issued in the nonconforming processing slip to the daily report creation system 10, it is possible to improve the accessibility to the nonconforming processing slip for the plant operator.

<Second embodiment>
Next, a function for preventing double registration of nonconforming information will be described as a second embodiment with reference to FIGS. 6 and 7. FIG.
In the first embodiment, the nonconforming sentences are extracted from the daily report data registered in the daily report creation system 10, and the nonconformance management system 20 automatically issues a nonconforming processing slip for the extracted nonconforming sentences. In many cases, multiple people are in charge, and a plant operator different from the operator who entered the daily report data manually registers the nonconformance information of the same content as the automatically issued nonconformance processing slip in the nonconformance management system 20. situation is expected. Then, two cases of the same nonconformity information are registered in the nonconformity management system 20, which is inappropriate from a management point of view and causes the plant operator to do unnecessary work. Therefore, double registration of nonconforming information is prevented by the processing described below.

(Double registration prevention process)
FIG. 6 is a flowchart showing an example of double registration prevention processing according to the second embodiment.
First, an operator performs a predetermined operation on the nonconformance management system 20 to display a nonconformity information processing screen. The operator inputs the date in the date of occurrence field in order to manually issue a non-conformance processing slip (step S20). FIG. 7 shows the nonconforming information processing screen 701 with the date (2021/01/15) entered in the date of occurrence column. When the date is input, the input unit 21 acquires information on the input date and outputs it to the control unit 22 . The control unit 22 refers to the nonconformance information database 241 and inquires whether there is a nonconformity processing slip for the same date as the input date of occurrence (step S21). The control unit 22 uses the date entered in the "occurrence date" column of the nonconforming information processing screen 701 to search the "daily report registration date" column of the database illustrated in FIG. If there is no non-conforming processing slip for the same day (step S22; No), the processing of FIG. 6 is terminated. The operator inputs other items on the nonconformance information processing screen 701 and manually issues a nonconformity processing slip.

If there is a nonconforming processing slip for the same date (step S22; Yes), the control unit 22 displays information on registered nonconforming processing slips that have the same date of occurrence entered on the screen and the date in the "daily report registration date" column. It is read from the nonconforming information database 241 and displayed on the screen of the nonconforming management system 20 (step S23). For example, the control unit 22 uses the read information to generate the registered nonconforming processing slip list screen 702 of FIG. 7, and displays this screen 702 as a popup. The operator looks at the non-conformity processing form list screen 702 and searches for non-conformance information that he was about to manually enter. Then, the control unit 22 updates the display contents of the nonconforming information processing screen 701 and displays the information in the “occurrence situation” column selected on the screen 702 in the “occurrence situation” column of the screen 701 . An example of display after display is shown in the nonconforming information processing screen 703 in FIG. Note that even if the information in the "occurrence status" column is corrected, the already generated access information is maintained as it is.

(effect)
As described above, according to the present embodiment, it is possible to prevent duplicate submission of nonconforming processing slips. In addition, it is possible to prevent the occurrence of useless work by the operator who was trying to input manually. For example, in the case of the nonconformity information exemplified in the first embodiment, it is possible to prevent the occurrence of two manual registration operations.

In the above example, if the date of occurrence is entered, a list of registered nonconformance processing slips can be displayed from the nonconformity information database 241, but the information that is the key for retrieval is not limited to the date of occurrence. For example, if a finder is entered instead of the date of occurrence, it may be configured to search for registered nonconformity information discovered by the same finder, or if the date of occurrence and the finder are entered, the control The unit 22 may search the nonconformance information database 241 using the input date of occurrence and information on the finder as key information, and display the search results on the nonconformity processing form list screen 702 .

<Third Embodiment>
Next, as a third embodiment, a function for automatically setting values to other input items on the nonconforming information processing screen will be described with reference to FIGS. 8 and 9. FIG.
FIG. 8 shows an example of the nonconforming information processing screen. On the nonconforming information processing screen 704, values are set in the "Occurrence Date" column and the "Occurrence Status" column. The nonconforming information processing screen 704 is displayed when the operator presses or selects, for example, the access information embedded in the daily report data immediately after the automatic registration process described in the first embodiment is performed. is displayed. As shown, the operator enters additional information in the "Title", "Severity", "Detector", "Event Classification", "Equipment Classification", and "System Classification" fields. There is a need. On the other hand, the automatic setting function of the third embodiment analyzes the contents of the nonconforming sentences in the "Occurrence situation" column by natural language processing technology, and estimates the event classification, equipment classification, and system classification. Then, the input values based on the estimation are set in the "event classification" column, the "equipment classification" column, and the "system classification" column, respectively, thereby reducing the burden of the operator's input work. Note that master information is registered in advance in the storage unit 24 for each of the event classification, equipment classification, and system classification. Event classification is to classify non-conforming events that occur during plant operation based on the type. From the point of view of event classification, non-conforming information includes vibration, abnormal sound/noise, deformation, performance deterioration, etc. are categorized. An event classification code is assigned to each classification in the event classification master of the storage unit 24 , and the event classification code is entered in the “event classification” column of the nonconforming information processing screen 704 . The equipment classification is to classify based on the equipment in which the nonconforming event occurred, and the nonconformity information is classified into pumps, boilers, conveying devices, and so on from the equipment classification point of view. A device classification code is assigned to each classification in the device classification master of the storage unit 24 , and the device classification code is entered in the “device classification” column of the nonconforming information processing screen 704 . The system classification is to classify based on the system of the plant to which the equipment in which the non-compliance event occurred belongs, and the non-conformity information is classified into fuel system, cooling water system, etc. from the viewpoint of system classification. . A system classification code is assigned to each classification in the system classification master of the storage unit 24 , and the system classification code is entered in the “system classification” column of the nonconforming information processing screen 704 .

(Automatic setting processing of input items)
Next, with reference to FIG. 9, automatic registration processing of input items according to the third embodiment will be described in detail. FIG. 9 is a flowchart showing an example of automatic registration processing of input items according to the third embodiment. Since the processing from step S1 to step S13 is the same as that of the first embodiment, it will be briefly described. First, an operator inputs daily report data into the daily report creation system 10 (step S1). The control unit 12 records the daily report data in the storage unit 14 (step S2). The document processing unit 121 divides the daily report data into sentence units (step S3), subdivides sentences into term levels by morphological analysis (step S4), absorbs terminology fluctuations (step S5), and identifies nonconforming sentences (step S6). The document processing unit 121 registers the identified non-conforming sentences in the non-conforming information database 241 (step S8), and notifies the non-conforming management system 20 of registration completion (step S9). In the nonconformity management system 20, the control unit 22 automatically issues a nonconformance processing slip (step S10), and registers access information to the automatically generated nonconformance processing slip in the nonconformity information database 241 (step S11). The control unit 22 notifies the daily report creation system 10 of completion of registration of the access information (step S12). In the daily report creation system 10, the document processing unit 121 embeds access information in the daily report data (step S13).

Next, the control unit 22 analyzes the nonconforming text and performs analysis (search processing for input items) from the viewpoints of event classification, equipment classification, and system classification. First, the control unit 22 morphologically analyzes the non-conforming sentences (text data) (step S14), and subdivides the non-conforming sentences into term levels. Next, the control unit 22 performs a process of absorbing term fluctuations for each of the divided terms (step S15). For example, the storage unit 24 stores dictionaries that define synonyms, synonyms, after-representation, etc. for each term. unified as a representative term. Next, the control unit 22 specifies the classification of the input items based on the subdivided and fixed terms (step S16). For example, from terms such as "conveyor" and "abnormal noise", the control unit 22 classifies the event classification of this nonconforming sentence into "abnormal noise/noise" and the equipment classification into "conveyor". The control unit 22 searches the event classification master registered in the storage unit 24 to identify the event classification code corresponding to "abnormal sound/noise". The control unit 22 similarly identifies the appropriate equipment and system from the terms after the morphological analysis for the equipment classification and system classification, refers to the equipment classification master and system classification master, and determines the equipment classification code and system classification code. Identify each. Next, the control unit 22 registers the specified input item in the nonconforming information database 241 (step S17). Specifically, the control unit 22 registers the identified event classification code in the "event classification code" item in the record of nonconformity information to be processed that has already been registered in the nonconformity information database 241, and registers the identified device classification code as " Register in the "Equipment classification code" item, and register the identified system classification code in the "System classification code" item. By this process, for example, when the access information is traced from the daily report creation system 10 and the non-conforming information processing screen 704 is inquired, the input fields of "event classification", "equipment classification", and "system classification" are already filled in. Appropriate value is set.

(effect)
As described above, according to the present embodiment, it is possible to omit the input item setting work in the nonconformity management system 20, and further reduce the input work load of the plant operator.

In the above example, the value of each item of "event classification code", "equipment classification code", and "system classification code" was automatically registered, but for example, a certain amount of nonconformity information in the nonconformity information database 241 is registered, the control unit 22 finds a similar event from the already registered nonconforming information based on the terms after the morphological analysis, and registers it in the nonconforming information database 241 in association with the found nonconforming information. Read out the information of the "title" item and "severity" item that have been registered, set this information to the "title" and "severity" in the newly registered (drafted) nonconformity information, and set it to the nonconformity information database 241 may be automatically registered in the

<Fourth embodiment>
Next, as a fourth embodiment, a function of presenting past similar nonconforming information will be described with reference to FIGS. 10 and 11. FIG.
In the first embodiment, nonconforming sentences are detected from daily report data registered in the daily report creation system 10, and a nonconforming processing form for the detected nonconforming sentences is automatically issued. Further, in the third embodiment, appropriate values are automatically registered for input items that are not set in the automatic ticketing. One of the purposes of the nonconformance management system 20 is to use it as a knowledge base for coping methods when an abnormality occurs. For this purpose, it is necessary to describe what actions were taken to resolve the problem after the abnormality was resolved, or what actions (repairs, parts replacement, etc.) were taken after the temporary situation was resolved. It is necessary to register information such as Therefore, in the fourth embodiment, by the processing described below, similar nonconformance information in the past is searched, a list of retrieved nonconformity information is presented, information to be added after automatic ticketing is entered, and currently occurring information is displayed. support decision-making regarding actions to be taken against nonconforming events

(Similar nonconformity processing form presentation processing)
FIG. 10 is a flowchart showing an example of similarity information presentation processing according to the fourth embodiment.
First, the operator accesses the automatically issued nonconformity processing slip (step S30). For example, the operator clicks the access information of the daily report data or performs a predetermined operation to start the nonconformance information processing screen, enter the date of occurrence, the person who discovered it, etc. to access. Then, the control unit 22 displays a nonconforming information processing screen 705 illustrated in FIG. 11 . Next, the control unit 22 acquires the information (excluding the data being browsed) of the "occurrence status" item of all nonconforming information registered in the nonconforming information database 241 (step S31). The control unit 22 collates the sentences in the "occurrence status" column of the nonconformity processing slip being browsed with the information in the "nonconformance sentence" item of other nonconformity information. Then, nonconforming information in which sentences of similar occurrence situations are registered is searched. Specifically, the control unit 22 performs morphological analysis on each of the sentences of the “occurrence situation” being browsed and the sentences of the “nonconforming sentence” item read from the nonconforming information database 241 (step S33). A process of absorbing the fluctuation is performed (step S34). The contents of these processes are the same as those described in steps S14, S15, etc. of FIG. Next, the control unit 22 divides the terms obtained by the morphological analysis of the text of the "occurrence situation" being browsed into the terms obtained by the morphological analysis of the text of the "non-conforming text" item read from the non-conforming information database 241. Based on this, the degree of association (similarity) between the non-conforming text being browsed and the non-conforming text read from the non-conforming information database 241 is calculated (step S35). A method of calculating the degree of relevance or similarity between sentences based on words contained in the sentences is known. For example, a method of vectorizing sentences based on the number of occurrences of words and calculating vector similarity, a method of calculating vector similarity between sentences using a distributed representation of each word using a tool such as word2vec, etc. It has been known. The control unit 22 uses an arbitrary method to calculate the degree of association (similarity) with the nonconforming text. Next, the control unit 22 identifies a nonconforming processing form that is similar to the nonconforming text being read out of the nonconforming texts read from the nonconforming information database 241 (step S36). For example, the control unit 22 extracts those whose relevance or similarity calculated in step S35 is equal to or greater than a threshold value, and identifies the nonconforming processing slip including the extracted nonconforming sentence as a similar nonconforming processing slip. Next, the control unit 22 presents the identified similarity-nonconforming processing slips in descending order of degree of relevance (step S37). A display example of similar nonconforming processing slips with a high degree of association is shown in the similar nonconforming processing slip list screen 706 in FIG. The control unit 22 generates a similar-unsuitable processing form list screen 706 that displays the contents of the "occurrence situation" item of the specified similar-unsuitable processing form and the degree of association calculated in step S35, and displays this screen 706 as a pop-up. The operator can refer to the contents of the displayed "Occurrence Status" column and "Relevance" column to consider how to deal with the currently occurring anomaly, etc., and how to deal with it. Also, the operator can refer to the contents of the displayed "Occurrence Status" column and "Relevance" column and enter the "Occurrence Status" column for the non-conforming processing slip being viewed. In addition, on the similar nonconforming processing form list screen 706 illustrated, a "draft creation" column is displayed, and can be selected for each similar nonconforming processing form. When the operator presses or selects the display (draft creation button) of "select this" in the "draft creation" column for one similar non-conformance processing form, the control unit 22 displays the selected similar non-conformity The nonconformance text of the "occurrence situation" of the processing slip is reflected in the "occurrence situation" column of the nonconformity information processing screen 705 being browsed. For example, the control unit 22 converts the device name appearing in the selected nonconformity text to the device name used in the nonconformity processing slip being viewed (for example, the device name associated with the device classification code entered in the name, device name included in the non-conforming text at the time of automatic filing)) to the non-conforming text displayed in the "Occurrence status" column during browsing, or replace it. Furthermore, even if the nonconformity statement displayed in the "Occurrence status" column is changed, the access information to the nonconformance processing slip developed in the daily report creation system 10 is not changed. Accessibility can be guaranteed. As a result, the work load on the operator can be reduced.

(effect)
Conventionally, it has been possible for an operator to actively retrieve data registered in the nonconformance information database 241 using the nonconformity management system 20 (pull type). However, with the pull-type search, it is up to the operator whether or not to query past non-conformance information. On the other hand, according to the present embodiment, when the operator accesses the automatically issued nonconformity processing slip, the automatically issued nonconformity information is compared with past nonconformity information stored in the nonconformity information database 241. Then, the nonconforming management system 20 actively presents past nonconforming processing slips that are likely to be related in descending order of relevance (push-type search function; similar nonconforming processing slip list screen 706). As a result, it is possible to use the information as reference information when determining a policy for responding to nonconforming events that are occurring, and as a result, it is possible to improve the efficiency of responding to nonconforming events. In addition, the operator must enter the description of the determined countermeasure policy in the "Occurrence situation" column. The burden can be reduced. Furthermore, the burden of input work can be greatly reduced by pressing the draft creation button. In the process of FIG. 11, the similar non-conforming processing form list screen 706 is automatically displayed. etc.) is performed, the processing after step S31 may be executed.
