[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-276003 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, digitalization has been progressing at production facilities such as chemical plants, and various data related to production operations are now being collected and managed. The operation and management of such digitalized production facilities requires various operational decisions based on the relationships between individual pieces of data contained in a wide variety of data. For example, to efficiently respond to an alarm during operations, a user must select the necessary data from among various other data when notified of an alarm. However, the relationships between individual pieces of data that form the basis for such operational decisions have traditionally been determined based on individual skills and know-how. This has resulted in biases in the response methods used by each user during operations. However, existing systems have made it difficult to evaluate the level of each individual's know-how. As a result, it has been difficult to identify experts in a specific area of ​​know-how and, ultimately, to improve the system based on the work history of these experts. The prior art documents do not take the above mentioned problems into consideration. For these reasons, in order to efficiently manage the operation and management of digitalized production sites, an information management system that can visualize the skills and know-how of individuals to determine the relationships between individual pieces of data is desirable. Ultimately, it is hoped that the visualized skills and know-how of individuals will contribute to the efficient identification of users who should be referred to and the simplification of creating appropriate personnel allocation plans. [Means for solving the problem]

[0005] In order to achieve the above-mentioned objectives, a typical information management system and information management device comprises a memory unit that stores information on multiple types of data groups including data related to facility management and facility performance data, relationship link information that is information indicating the relationships between individual data included in the multiple types of data groups, and specialized skill information that is information indicating the type of specialized skill related to the relationship link information; an input unit to which information on operation instructions that a user will give to the multiple types of data groups is input; and a control unit that outputs an indicator indicating the user's level of understanding of the specialized skill that gave the operation instruction based on the information on the operation instruction and the specialized skill information input to the input unit. Furthermore, a typical information management method includes a step in which a computer acquires information on multiple types of data groups including data related to facility management and facility performance data, relationship link information which is information indicating the relationships between individual data included in the multiple types of data groups, and specialized skill information which is information indicating the type of specialized skill related to the relationship link information; an input acceptance step in which a user accepts input regarding information on operation instructions to be given to the multiple types of data groups; and a step in which, based on the information on the operation instructions and the specialized skill information received in the input acceptance step, an index indicating the level of understanding of the specialized skill of the user who gave the operation instruction. [Effects of the Invention]

[0006] According to the present invention, it is possible to visualize the user's level of understanding of the specialized skill of determining the relationship between individual pieces of data. The problems, configurations, and effects other than those described above will become clear from the following description of the embodiment. [Brief explanation of the drawings]

[0008] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In this specification and drawings, components having substantially the same functions or configurations are denoted by the same reference numerals, and redundant explanations will be omitted. In the following examples, an example in which the information management system of the present invention is applied to a chemical plant will be mainly described, but the embodiment of the information management system of the present invention is not limited to this example. In addition to chemical plants, the information management system of the present invention can be applied to production bases in various fields, such as energy plants including power plants, steel plants, and assembly plants. [Example]

[0009] 1 is a configuration diagram of a chemical plant management system. The chemical plant management system includes a management server 10, a user terminal 20, a distributed control system (DCS) server 30, an equipment maintenance management server 40, and a document management server 50. Here, the chemical plant management system is also called an information management system.

[0010] The management server 10 is a computer having a communication interface 11, a storage unit 12, and a control unit 13. The communication interface 11 communicates with the user terminal 20, the DCS server 30, the facility maintenance management server 40, and the document management server 50. The storage unit 12 stores various data received from the user terminal 20, the DCS server 30, the equipment maintenance management server 40, and the document management server 50. The storage unit 12 also stores various programs and data generated by the management server 10. The control unit 13 is, for example, a CPU (Central Processing Unit), and realizes various functions by reading and executing programs stored in the storage unit. The functions realized by the control unit 13 include control of the chemical plant and evaluation of user skills.

[0011] Like the management server 10, the user terminal 20, the DCS server 30, the equipment maintenance management server 40, and the document management server 50 are computers having a communication interface, a storage unit, and a control unit.

[0012] The user terminal 20 is a computer used by a user who performs operation and management tasks for a chemical plant, and has an input unit 21 and a display unit 22. The user terminal 20 accepts operations from the user via the input unit 21. The user terminal 20 accesses the management server 10 based on the user operation and displays the status of the chemical plant on the display unit 22. The user terminal 20 also accesses the management server 10 based on the user operation and controls the status of the chemical plant.

[0013] The DCS server 30 acquires various data from the production equipment and facility equipment of the chemical plant and transmits it to the management server 10. This data includes alarm signals 31 that notify of abnormalities in the plant, measurement data 32 that indicate the measurement results of sensors, operation data 33 that indicates the status of the equipment, etc. The DCS server 30 also controls the production equipment etc. based on control requests received from the management server 10.

[0014] The facility maintenance management server 40 holds data relating to inspections and repairs of the chemical plant as maintenance work data 41. The facility maintenance management server 40 can transmit the maintenance work data 41 to the management server 10.

[0015] The document management server 50 holds chemical plant design data 51 and manual data 52. The document management server 50 can transmit the design data 51 and manual data 52 to the management server 10.

[0016] 2 is a configuration diagram of the management server 10. The management server 10 has a communication interface 11, a storage unit 12, a control unit 13, a memory 14, an input unit 15, and an output device 16. The storage unit 12 stores programs such as an understanding analysis program, a data analysis program, and a data input / output program. The storage unit 12 also stores related link information, specialized skill information, skill map information, user information, work information, equipment performance data, equipment management data, operation history data, evaluation data, work performance data, and the like.

[0017] The control unit 13 reads out the programs from the storage unit 12, expands them in the memory 14, which is a main storage device, and executes them sequentially to realize various functions. The input unit 15 is a keyboard, a pointing device, etc. The output device 16 is a display, etc. The input unit 15 and the output device 16 are direct input / output interfaces for the management server 10.

[0018] The control unit 13 can output an index indicating the user's level of understanding of the specialized skill based on the data stored in the storage unit 12. The memory unit 12 stores information on multiple types of data groups including data related to equipment management in chemical plants and performance data on equipment, relationship link information which is information indicating the relationships between individual data included in the multiple types of data groups, and specialized skill information which is information indicating the types of specialized skills related to the relationship link information. The data related to facility management may include, for example, maintenance work data 41 received from the facility maintenance management server 40, and design data 51 and manual data 52 received from the document management server 50. These data may be received and stored in the storage unit 12, or may be configured to access the facility maintenance management server 40 or the document management server 50 as needed to use the data.

[0019] The performance data of the facility may include operation data 33 of the facility and equipment in the plant, measurement data 32 of sensors acquired to monitor the process, and alarm signals 31 that notify that the operation data 33 or measurement data 32 has deviated from a standard. These data may be received from the DCS server 30 and stored in the storage unit 12, or may be configured to be accessed as needed by the DCS server 30 for use.

[0020] In this way, the necessary data may be stored in the storage unit 12 of the management server 10, or may be stored in a distributed manner across multiple servers connected via a network. In a distributed storage configuration, the collection of the storage units of the servers serves as the storage unit of this system. In a chemical plant, different servers may be used for different departments or roles, such as the manufacturing department and the maintenance department, and this system can also be applied to such information management systems.

[0021] The memory unit 12 stores user data including identification information for managing users, operation history data which is a history of operation instructions given by a user identified by the user's identification information, work reports indicating the work to be performed by the user, and work performance data given by a user identified by the user's identification information. The storage unit 12 also stores relational link information. Traditionally, a user's decision on which data to access after reviewing certain data has largely depended on personal experience and know-how. For example, a skilled user with a high level of understanding of specialized skills can efficiently access the necessary data, while a user with a low level of understanding may not be able to identify the necessary data. The relational link information indicates the relationship between certain data and the data to be referenced after that data, and is also called a relational link. By referencing this relational link information, it is possible to extract information on related data using a certain data as the source data. Here, for two data items linked by a relational link, the source data is referred to as the From data, and the data extracted as data related to the From data is referred to as the To data. In other words, the data to be referenced after the From data is the To data. The From data may also be referred to as "first information" and the To data as "second information." Furthermore, multiple To data items may exist corresponding to one From data item. The related link information may be predefined or may be generated by analyzing the operation history of an expert. The related link information may be added or updated by the user as appropriate. Presenting the related link information to the user can assist in efficient operation and can also be used to evaluate the user's specialized skills.

[0022] The control unit 13 executes a data input / output program to perform processing related to the input / output of various data. The control unit 13 executes a data analysis program to analyze the state of the chemical plant and present related link information corresponding to the current state. The related link information corresponding to the current state is linked to candidates for data to be checked next, thereby supporting user operations. The control unit 13 executes the understanding analysis program to calculate an index indicating the user's level of understanding of a specialized skill. For example, information on related link information used by the user may be extracted from the user's operation history, and an index indicating the user's level of understanding of a specialized skill related to the related link information included in the operation history may be calculated based on information on the relationship between the related link information and the specialized skill. For example, the more frequently the related link information included in the operation history is used, the higher the user's level of understanding of the related specialized skill may be evaluated. Furthermore, to improve the accuracy of the calculation of the index indicating the user's level of understanding of a specialized skill, it is desirable to exclude information on operations performed despite not actually having a high level of understanding. To this end, for example, if multiple related link information is used in the operation history for a certain task, information on the order in which the multiple related link information was used and the time when the To data was referenced may be extracted, and an index indicating the user's level of understanding of the specialized skill may be calculated based on this information. For example, since an inexperienced user may select To data files that they do not actually reference, such information from the operation history may be excluded when calculating the index indicating the user's level of understanding of the specialized skill. Specifically, if the index indicating the level of understanding of a specialized skill is lower than a predetermined standard and the reference time of the To data included in the relationship link information related to the specialized skill is shorter than a predetermined threshold, information regarding the use of the relationship link information related to the corresponding specialized skill may be excluded from the calculation of the index of the level of understanding of the specialized skill. As another example, since it is conceivable that an inexperienced user may arrive at the file of desired information after looking through various files that do not need to be referenced, such information in the operation history may be excluded from the calculation of the index of the level of understanding of the specialized skill. Specifically, if the index indicating the level of understanding of a specialized skill is lower than a predetermined standard and the related link information included in the operation history was referenced relatively earlier in the order of reference, information regarding the use of the relationship link information related to the corresponding specialized skill may be excluded from the calculation of the index of the level of understanding of the specialized skill. Furthermore, without being limited to the above examples, in the understanding analysis program, what information is obtained from the user's operation history and how it is taken into consideration in calculating the index of understanding of the specialized skill may be determined appropriately depending on the nature and field of the specialized skill.

[0023] FIG. 3 is an explanatory diagram of data used as first information and second information. As shown in FIG. 3, the data used as first information and second information is stored on one of the servers. Furthermore, each server manages the data storage destination using a hierarchical directory structure. Therefore, the target data can be identified by the file server ID and the directory ID that includes the directory hierarchical structure. For example, data can be identified using "file server ID / directory ID / file data ID" as identification information. Identification information structured in this way is called a structured ID. In addition, structured IDs are not limited to file storage locations. They can be created from inclusion relationships shown in various data, such as hierarchical directories, tables in database schemas, column and row identifiers in database schemas, inclusion relationships in the chapter and section structure of manual documents, and inclusion relationships due to indentation, as well as information indicating data relationships such as references to attached documents, notes, and annotations. Inclusion relationships shown in various data are also called path structures. Inclusion relationships in a document's chapter and section structure can be identified from the hierarchy established in the document, such as the document title, chapters, sections, headings, and words. Structured IDs are structured to represent inclusion relationships shown in various data themselves and the path structures used to manage them in a uniform format, and they indicate structured inclusion relationships, so to speak.

[0024] In Fig. 3, the identification information of a structured ID is associated with a server, an information type, the structured ID itself, and a name for screen display. The information type indicates the type of structured ID classified by content, such as "alarm (input)," "document file," or "inspection work." The name for screen display is the name used when displaying the structured ID on the display unit.

[0025] 4 is an explanatory diagram of the relationship link information. In the relationship link information table, mutual relationship link information, that is, a relationship link management number that identifies a relationship link, is associated with From data, To data, creator, priority, number of references, and evaluation.

[0026] The creator is the user who defined the relationship link. The priority, number of references, and rating are used to determine which To data with a relationship link to the same From data should be displayed preferentially. "Evaluation" is an index indicating whether the To data is useful in resolving the event linked to the From data, i.e., an evaluation value of usefulness. For example, it can be obtained by a user checking the To data and then inputting whether or not the content was useful. When multiple evaluation inputs are obtained for one relationship link, any statistical method can be used to determine the evaluation value of the relationship link. Furthermore, the evaluation value may be calculated automatically, without relying on the user input value, depending on whether or not the event related to the From data was actually resolved. For example, if the event related to the From data was actually resolved, the evaluation value of the To data referenced in the operation at that time may be set to be higher than the evaluation value of the To data that was not referenced.

[0027] The "reference count" indicates the number of times the relationship link has been referenced. The reference count is calculated by adding up the reference counts of all users. The "priority" is determined based on information about the user's operational instructions, such as the number of times referenced, and information about the evaluation value. For example, the priority is calculated to decrease as the number of times referenced increases, and the smaller the priority value, the higher the item is displayed in the search. Also, the priority is calculated to decrease as the evaluation value increases, and the smaller the priority value, the higher the item is displayed in the search. This makes it possible to preferentially display to the user To data that is actually evaluated as useful or that is actually used frequently, contributing to improving the efficiency of user operations and supporting decision-making.

[0028] 5 is an explanatory diagram of user information. The user information includes a user management number, a user group name, a user name, a login ID, and a password, and can be used for user authentication.

[0029] 6 is an explanatory diagram of alarm history. When management server 10 receives alarm signal 31, it stores the operation date and time, structured ID identification number, structured ID, name, status, alarm message, and alarm level in association with each other. Alarm history is part of the performance data of the equipment.

[0030] Each alarm can be used as first information. The user checks the alarm and accesses the data for dealing with it. In this case, the data for dealing with it becomes second information. In this embodiment, an alarm is shown as an example of first information, but production plan information, maintenance plan information, etc. can also be used as first information. For example, this system may be applied to a situation where appropriate data (such as the operating status of related equipment, necessary manuals, etc.) is referenced from production (maintenance) plan information for plant operation management during normal operation or when preparing for operation.

[0031] 7 shows an example of the second information when the first information is an alarm. If the first information (From data) is information about an error related to the compressor 1, the second information (To data) will be the pressure or temperature of the compressor 1.

[0032] 6 and 7, the first information may be information (such as an alarm) relating to the operating status of equipment in a chemical plant. In this case, the second information may include information relating to maintenance work on equipment related to the first information, information on manuals relating to equipment related to the first information, information on past operating status of equipment related to the first information, etc.

[0033] The first information may be information about a production plan or a work plan for a chemical plant. In this case, the second information may include information about a manual for equipment or work related to the first information, information about the past operating status of equipment related to the first information, etc. Similarly, the first information may be information about a maintenance work plan for a chemical plant. In this case, the second information may include information about past maintenance work for equipment related to the first information, information about manuals related to the equipment or work related to the first information, information about past operating conditions of the equipment related to the first information, etc.

[0034] 8 is an explanatory diagram of operation history data. The operation history data includes operation date and time, user name, display screen, screen operation content, and reference relationship links. Because this operation history data includes reference relationship links, it not only shows what operation was performed, but also which data was viewed to reach that operation.

[0035] Figure 9 is an explanatory diagram of the number of times related link information is referenced. The table shown in Figure 9 manages the number of times related link information is referenced and the average reference time for each user. Specifically, a unique number is assigned to each combination of user, From data, and To data, and the number of times each number is referenced is counted and the average reference time is calculated.

[0036] Using this table, the control unit 13 determines the level of understanding of a technical skill related to a certain related link depending on the number of times the link has been viewed. As an example, the control unit 13 determines that the greater the number of times, the higher the professional skill. Furthermore, the level of understanding may be determined based on the average reference time in addition to the number of references. At this time, depending on the type of To data, a user with less experience may have a longer reference time than a user with more experience, or the opposite may be true. Therefore, the product of the number of references and the average reference time may be used as an index to take these multiple factors into consideration. For example, the greater the product of the number of references and the average reference time, the higher the level of specialized skill. Another example is when a user simply opens the referenced data without understanding its contents. In such a case, the history of the operation instructions may be excluded from the calculation of the level of understanding of the specialized skill. For example, if the number of references is less than a predetermined threshold and the average reference time is less than a predetermined threshold, it is determined that the data has not been effectively used, and the level of understanding of the specialized skill is relatively low.

[0037] In Figure 9, the number of times a user has accessed and operated the To data of a relationship link for event information (From data) is stored as the number of times it has been accessed. For similar event information (From data), if the number of times the To data has been accessed by the relevant user and other users is displayed on the screen, it is possible to visualize which user has accessed it and how many times, which can assist the operator in making decisions.

[0038] Fig. 10 is an explanatory diagram of specialized skill information. The specialized skill information includes the type, specialized skill, structured ID of related data, related relationship link information ID, display screen, screen operation type, etc. Examples of the type are "DCS system," "facility maintenance," "whole system," etc. Examples of specialized skills are "alarm response," "predictive analysis," "mechanical equipment," "water supply and drainage equipment," etc.

[0039] Since the specialized skill information includes the related link information ID selected as the second information (To data) in the related link, the level of understanding of specialized skills can be visualized by comparing the user's operations with the related link information. The user's level of understanding of specialized skills can be created as a skill map, which will be described later. Skill maps are basically created based on related link information IDs, but to create more accurate skill maps, related structured IDs, display screens, and types of screen operations can also be used.

[0040] For From data and To data that are directly related to specialized skills (e.g., specialized skill "predictive analysis" = To data related to predictive analysis trend graphs and manuals), simply viewing the file can be used as a reference for calculating specialized skills. Similarly, for display screens, the output of specific display screens can be used as a reference for calculating specialized skills. In addition, skill maps can be generated that take into account operation types that are directly related to specialized skills (e.g., registering corresponding relationship links, specialized skills (drawing management and the operation type "drawing file registration"), etc.).

[0041] 10, for convenience, one relationship link corresponds to one specialized skill, but multiple relationship links may correspond to one specialized skill. Conversely, the link may be left blank.

[0042] Furthermore, information on the degree of association between specialized skills may be automatically generated from information on the relationship links of the structured IDs. In this case, the control unit 13 refers to the relationship link information and specialized skill information in the storage unit 12, and determines and outputs the degree of association between a first specialized skill and a second specialized skill of a different type from the first specialized skill.

[0043] The information on the relevance of specialized skills may be defined in multiple stages or may be defined as a score. Also, it may be calculated in a composite manner using multiple calculation methods. For example, two or more specialized skills corresponding to related links linked to the same type of From data or To data may be considered to be related to each other. As another example, it is possible to obtain From data and To data linked by one or more related links associated with a first specialized skill, and From data and To data linked by one or more related links associated with a second specialized skill, and calculate an index indicating the degree of association according to the number of pieces of data common to both (for example, the greater the number of pieces of data, the higher the degree of association). This calculation method may be performed for each From data and each To data.

[0044] Regarding specialized skills that correspond one-to-one to structured IDs, the specialized skills corresponding to the structured IDs that are related by a relation link may be set to have a high degree of relevance to each other. As another example, if multiple users have a common combination of two or more specialized skills for which the understanding index is greater than a predetermined standard, the relationship between the combination of specialized skills may be set to be relatively high. In addition to using information about relationship links related to specialized skills, information about structured IDs associated with specialized skills may be used to generate information about the degree of association between specialized skills from the structured ID information. This is possible by utilizing the fact that structured IDs are structured to uniformly represent the inclusion relationships indicated in various data themselves and the path structures used to manage them, i.e., they indicate structured inclusion relationships. For example, information about a first structured ID associated with a first specialized skill and a second structured ID associated with a second specialized skill may be obtained, and the extent to which the path structures indicated by the first structured ID and the second structured ID have common path structures may be evaluated. Based on the results of this evaluation, information about the degree of association between the first specialized skill and the second specialized skill may be calculated. For example, the degree of association between the first specialized skill and the second specialized skill may be evaluated as being higher the higher the percentage of elements that make up the path structure indicated by the first structured ID that are common to elements that make up the path structure indicated by the second structured ID.

[0045] Fig. 11 is an explanatory diagram of work information. The work information in Fig. 11 includes the work process, scheduled work time, work content, equipment classification, work location, person in charge, and structured ID. By referring to this work information, the content of the work that the user should perform can be identified.

[0046] Figure 12 is an explanatory diagram of work performance data. Work performance data includes the person in charge, work process, work date and time, start time, finish time, inspection time, and structured ID, and is managed by assigning a unique number to each combination of these. This data makes it possible to manage what kind of work a user performed and how long it took.

[0047] Fig. 13 is an explanatory diagram of skill map information. The skill map includes the classification of specialized skills, the name of the specialized skill, the pass mark for the specialized skill evaluation, and the evaluation mark for each user, and assigns a unique number to each combination of these. The pass mark can be used to propose training plans for users or to highlight them in displays.

[0048] FIG. 14 is a flowchart showing a processing procedure related to skill evaluation. First, the input unit 21 of the user terminal 20 or the input unit 15 of the management server 10 accepts input of the user's identification information, and the control unit 13 authenticates the user by referring to the user information (step S101).

[0049] Thereafter, the control unit 13 determines the From data to be displayed on the display screen from the information of the plurality of types of data groups (step S102). The control unit 13 displays the From data on the display unit 22 of the user terminal 20 or the display screen of the output device 16 of the management server 10 (step S103). Here, examples of the From data may be information on the operating status of equipment in the plant including predetermined alarm information, information on the production plan in the plant, information on the maintenance work plan in the plant, etc.

[0050] After step S103, the control unit 13 determines whether or not selection of From data has been performed (step S104). If selection of From data has not been performed (step S204; No), the process returns to step S102.

[0051] If the From data is selected (step S104; Yes), the control unit 13 identifies the To data related to the selected From data based on the relationship link (step S105). The control unit 13 displays an item list of the identified To data on the display screen (step S106). Here, if the selected From data is information about the operating status of equipment in a plant, particularly alarm information, one or more To data items may be identified and displayed based on a relational link as information necessary to respond to the alarm information. In this case, the To data may be information about maintenance work for equipment related to the alarm information (From data), information about a manual for the equipment related to the alarm information (From data), and information about the past operating status of the equipment related to the alarm information (From data). This makes it possible to efficiently collect information necessary to respond to alarm information that has occurred in a plant. If the selected From data is information related to a production plan in a plant, one or more To data items may be identified and displayed based on a relational link as information necessary for managing and executing the production plan. In this case, the To data may be information on a manual related to equipment or work related to the information related to the production plan, which is the From data, and information on the past operating status of equipment related to the information related to the production plan, which is the From data. This makes it possible to efficiently collect information necessary for managing and executing the production plan in a plant. If the selected From data is information about a maintenance work plan in a plant, one or more To data items may be identified and displayed based on a relational link as information necessary for managing and executing the maintenance work plan. In this case, the To data may be information about past maintenance work for equipment related to the From data maintenance work plan, information about manuals related to the equipment or work related to the From data maintenance work plan, and information about the past operating status of the equipment related to the From data maintenance work plan. This makes it possible to efficiently collect information necessary for managing and executing maintenance work plans in a plant. Furthermore, when the list of To data items is displayed on the display screen, the number of times the To data was referenced for the selected From data may be acquired for each user, and the number of times the To data was referenced for each user in the same situation may be displayed in association with each To data. This makes it possible to understand which To data each user referenced when responding to the same From data, and provides support for the user's decision-making when actually responding.

[0052] Thereafter, the control unit 13 acquires the To data based on the information of the operation instruction to select the To data, and displays it on the display screen (step S107). The control unit 13 also acquires information of the evaluation value input to the input unit 21 or the input unit 15 (step S108). Thereafter, the control unit 13 stores information about the operation instruction of the identified user in the storage unit 12, and ends the process.

[0053] 15 is a flowchart showing a processing procedure related to the skill map. First, the control unit 13 acquires information related to user operation instructions stored in the storage unit 12 (step S201). The control unit 13 determines whether or not there is a user who has a user operation history that has not yet been reflected in the skill map (step S202). If there is no user who has a user operation history that has not yet been reflected in the skill map (step S202; No), the control unit 13 ends the processing.

[0054] If there is no user whose user operation history has not yet been reflected in the skill map (step S202; Yes), the control unit 13 selects the corresponding user (step S203). The control unit 13 calculates an index indicating the user's understanding of the specialized skill for the selected user using the specialized skill information and information on the type of To data referenced for the From data included in the operation instruction, the reference time, and the number of references (step S204). The control unit 13 updates the skill map by storing the calculated index information in the storage unit 12 in association with the user (step S205), and ends the process.

[0055] Here, we will explain how to calculate an index that indicates the level of understanding of specialized skills. The index that indicates the level of understanding of specialized skills can be calculated based on items such as response, current situation understanding, setting registration, and work execution. As an example, evaluation points are calculated for these items, and the evaluation points for each item are weighted for each user and each specialized skill.

[0056] Response is an item that indicates understanding through response to the event that occurred. For example, the number of times the user selected related information (related link) from the screen and the number of times new related information (related link) was assigned from the screen are used as evaluation points for this item. The current situation understanding is an item that indicates understanding through screen operation. For example, the evaluation points for this item include the number of times an event occurrence (alarm information, today's work instructions) was confirmed, the number of times detailed information on the target point or target file was displayed, the number of times the current value of the target point was displayed from the graphic screen, the number of times a trend graph of the target point was displayed, and the number of times the alarm history was displayed. Setting registration is an item that shows understanding through report creation and allocation of structured IDs. For example, the evaluation points for the relevant items include the number of times additional structured IDs are registered from the screen, the number of times a work schedule is registered, and the number of times a report is registered when an alarm occurs or during maintenance inspection. Work execution is an item that indicates understanding through work. For example, the work time spent actually performing inspection work is used as the evaluation score for this item.

[0057] FIG. 16 is a specific example of a skill map display. In FIG. 16, selecting "DCS System" displays the evaluation scores of each user for specialized skills related to the DCS system. In this way, by selecting the type of specialized skill, the skills of each user can be displayed in a list. In addition, when a specific specialized skill is specified, it is also possible to display users in a ranking format according to their level of understanding of that specialized skill.

[0058] Furthermore, the control unit 13 can determine and output candidate users for dealing with an event that has occurred based on the ranking of users in terms of required specialized skills. The control unit 13 can also suggest information about specialized skills that are recommended for acquisition based on the evaluation scores of each specialized skill of a user and the degree of association between the specialized skills. That is, the control unit 13 can recommend specialized skills that are related to skills that the user has already acquired but that the user has a low level of understanding of as training targets. In addition, if related specialized skills are set according to the user's work content and job title, the control unit 13 can also display specialized skills that match the user's work content and job title with priority.

[0059] FIG. 17 shows a modified example of skill display. In FIG. 17, an index relating to the time required for a task is displayed along with the skill evaluation score. The index relating to the time required for a task can be calculated using any calculation method based on the actual time required for the task. As shown in the example screen in FIG. 17, by displaying an index indicating the level of understanding of a specialized skill and an index of the time required for the task in association with each other on the display unit, the user's ability can be evaluated from multiple angles.

[0060] As described above, the disclosed information management system includes a memory unit 12 that stores information on multiple types of data groups including data related to facility management and facility performance data, relationship link information that is information indicating the relationships between individual data included in the multiple types of data groups, and specialized skill information that is information indicating the type of specialized skill related to the relationship link information, an input unit 21 to which information on operation instructions that a user will give to the multiple types of data groups is input, and a control unit 13 that outputs an index that indicates the level of understanding of the specialized skill of the user who gave the operation instruction, based on the information on the operation instruction and the specialized skill information input to the input unit. This makes it possible to visualize the user's level of understanding of specialized skills, which in turn contributes to the efficiency of identifying users who should be used as references and the simplification of creating appropriate personnel allocation plans based on the visualized level of understanding of individual specialized skills.

[0061] The disclosed system further includes a display unit 22 that displays first information, which is information related to a specific operation at the chemical plant, from among the data included in the plurality of types of data groups, and the control unit 13 causes the display unit 22 to display one or more pieces of second information, which are identified as information related to the first information from among the data included in the plurality of types of data groups based on the first information and the relationship link information, and the operation instruction information is information indicating the second information referenced by the user in relation to the first information. In this way, the user's level of understanding of specialized skills can be visualized by using the timeline of operations, i.e., how the user references the data.

[0062] As an example, the first information is information regarding the operating status of the equipment, and the second information includes at least information regarding maintenance work on the equipment related to the first information, information regarding manuals regarding the equipment related to the first information, and information regarding the past operating status of the equipment related to the first information. As another example, the first information is information relating to a production plan, and the second information includes at least information relating to a manual regarding equipment or work related to the first information, and information relating to the past operating status of the equipment related to the first information. As another example, the first information is information relating to a maintenance work plan, and the second information includes at least information relating to past maintenance work of equipment related to the first information, information relating to manuals related to the equipment or work related to the first information, and information relating to the past operating status of the equipment related to the first information. In this way, the time series of user operations can be used for operational status, production planning, and maintenance work.

[0063] The disclosed system also displays, for each user, the number of times the user has referred to the second information displayed in relation to the first information. In this way, visualizing information about which user has referenced a document and how many times it has been referenced can assist the operator in making decisions.

[0064] In addition, index information indicating an evaluation of the management work related to the first information is further input to the input unit, and the control unit outputs an evaluation value indicating the usefulness of the second information displayed in relation to the first information based on the index information indicating the evaluation of the management work related to the first information and the operation instruction information. Furthermore, the control unit determines the second information to be displayed on the display unit based on information on an evaluation value indicating the usefulness of the second information displayed for the first information. Therefore, the usefulness of the second information can be provided, and subsequent operations can be effectively supported.

[0065] The control unit also outputs information indicating the degree of association between a first specialized skill and a second specialized skill of a different type from the first specialized skill, based on the relationship link information and the specialized skill information. This allows users to be informed of how specialized skills are related.

[0066] In addition, the control unit outputs information on candidate users to handle operational tasks related to the first information based on the first information, the specialized skill information, and information on an index indicating the level of understanding of the specialized skill. Therefore, the user who is most suitable for the event that has occurred can be assigned to the event.

[0067] In addition, the memory unit stores relevance information, which is information indicating the relevance between a first specialized skill included in the specialized skill information and a second specialized skill of a different type from the first specialized skill, and the control unit outputs information on specialized skills that are recommended for acquisition to the user based on the relevance information and an index indicating the level of understanding of the specialized skill. This can contribute to improving the skills of users.

[0068] The disclosed system also includes a display unit 22, and the control unit causes the display unit to display an index indicating the level of understanding of the specialized skill for each user and for each type of specialized skill. The memory unit also stores work information including information indicating work items at the chemical plant and work performance information regarding the performance of work performed by users, and the control unit calculates an index regarding the time required for work for each user and for each work item based on the work information and the work performance information, and displays the index information on the display unit in association with an index indicating the level of understanding of the specialized skill. This allows the user's level of understanding of specialized skills to be comprehensively evaluated and displayed.
