[0026] <Comparative Example> A gas turbine performance testing system according to a comparative example (claim 1 of Patent Document 1) includes a server (200) communicatively connected to a client computer (145) via a communication network (140), a transducer system (110) configured to acquire one or more functional parameters of a gas turbine (105), and a signal converter (115) communicatively connected to the transducer system (110) and configured to convert the acquired one or more functional parameters into gas turbine operating data provided to the server for transmission to the client computer (145). and an automated gas chromatograph (135) communicatively coupled to the server (200), the automated gas chromatograph (135) configured to automatically analyze test samples of natural gas used to operate the gas turbine (105) and to provide analytical information obtained from the test samples to the server (200) for propagation to the client computer (145) to combine with the gas turbine operating data to obtain gas turbine performance test results.

[0027] However, there is room for improvement in terms of performing maintenance and inspection of gas chromatographs precisely and easily.

[0028] <Embodiment> Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. In each drawing, parts having the same configuration or function are denoted by the same reference numerals. In the description of this embodiment, duplicated descriptions of the same parts may be omitted or simplified as appropriate.

[0029] (Management system) FIG. 1 is a diagram illustrating an example of the configuration of a management system 1 according to an embodiment. The management system 1 manages various data, including operation history, alarm data, analysis data, and device setting information, related to various devices 50 and process lines 60 installed in a plant P. The management system 1 includes a server device 10, a control system 20, a gas chromatograph 30, and a client device 40. In this embodiment, the server device 10, the control system 20, and the gas chromatograph 30 are installed within the premises of the plant P. However, the server device 10 may be installed outside the premises of the plant P while being able to communicate with the control system 20 and the gas chromatograph 30. The server device 10 can communicate with the client device 40 via various networks N, including, for example, an intranet and the Internet.

[0030] The plant P is a facility of any kind in which the gas chromatograph 30 is installed. The plant P is, for example, an LNG plant, an oil refinery, a petrochemical plant, or the like, but is not limited to these.

[0031] The process line 60 is a line through which a gas flows that is the measurement target of the gas chromatograph 30. The process line 60 may be configured, for example, with a pipe through which the gas flows, a valve, and the like.

[0032] The gas chromatograph 30 is a device that uses gas chromatography to analyze gases, including identifying and quantifying the gases flowing through the process line 60. As will be described later with reference to FIG. 5 , the gas chromatograph 30 includes a sample valve 342, a column 343, and a detector 344. The gas chromatograph 30 manages the history of manual operations performed on the gas chromatograph 30, detects abnormalities that occur in the gas chromatograph 30, and manages the device setting information of the gas chromatograph 30. The gas chromatograph 30 transmits various data, including gas analysis data, operation history, alarm data, and device setting information, to the server device 10. The gas chromatograph 30 also updates its operation details and device setting details under the control of the server device 10. The number of gas chromatographs 30 is arbitrary.

[0033] The equipment 50 is various devices that constitute the plant P. For example, the equipment 50 may include valves, tanks, and the like that are provided upstream or downstream of the process line 60. Alternatively, the equipment 50 may include valves, switches, heaters, and the like of the gas chromatograph 30 itself.

[0034] The control system 20 is a device that controls the operation of the device 50 and measures physical quantities related to the device 50. For example, the control system 20 may measure information related to the operation and maintenance of the device 50, such as the device 50 installed upstream or downstream of the process line 60, or the valves and heaters of the gas chromatograph 30, which the gas chromatograph 30 itself cannot obtain. Specifically, the control system 20 may manage an operation history related to plant operation and detect abnormalities that occur in the plant P. The control system 20 transmits various data, including an operation history and alarm data, of the plant P to the server device 10. Furthermore, the control system 20 updates the operation details and device settings, etc., based on the control of the server device 10.

[0035] The server device 10 as an information processing device according to this embodiment is a computer that receives and manages various data relating to the equipment 50 and the process line 60 from the control system 20 and the gas chromatograph 30, and controls the operations of the control system 20 and the gas chromatograph 30. The server device 10 communicates with the client device 40 via the network N, transmits various data relating to the equipment 50 and the process line 60 to the client device 40, and receives instructions for the control system 20 and the gas chromatograph 30. The server device 10 is realized by a general-purpose computer such as a WS (Workstation) or a PC (Personal Computer), but may also be realized by a device dedicated to plant management.

[0036] The client device 40 as a terminal device according to this embodiment is a computer that displays various data related to the equipment 50 and the process line 60 received from the server device 10 to a user and accepts operations from the user. In response to operations from the user, the client device 40 transmits instructions for the control system 20 and the gas chromatograph 30 to the server device 10. The client device 40 is realized by, for example, a general-purpose computer such as a PC or a tablet terminal, but may also be realized by a device dedicated to plant management.

[0037] In the above configuration, the server device 10 transmits not only various data from the gas chromatograph 30 but also various data from the control system 20 to the client device 40, and displays this information together. Therefore, a user of the client device 40 can refer to not only various data acquired by the gas chromatograph 30 but also various data that the gas chromatograph 30 itself cannot acquire, thereby obtaining more detailed information about abnormalities in the gas chromatograph 30 and performing appropriate maintenance. For example, the user can distinguish between abnormalities in the gas chromatograph 30, abnormalities in the control system 20, and abnormalities in the equipment 50. Furthermore, the server device 10 learns the replacement cycles of components of the gas chromatograph 30, such as columns, using the measured gas flow rate, replacement time, and replacement cycle of the gas chromatograph 30 as learning data, and predicts the replacement cycles of the components. The server device 10 notifies the client device 40 of the need to replace the components based on the predicted replacement cycles, and displays the notification to the user. Therefore, the user can perform maintenance, such as component replacement, at the appropriate time. As described above, according to the configuration of this embodiment, maintenance and inspection of the gas chromatograph 30 for abnormalities can be performed more precisely and simply.

[0038] (Server device) Fig. 2 is a block diagram showing an example of the configuration of the server device 10 in Fig. 1. The server device 10 is one or more computer devices that can communicate with each other. As shown in Fig. 2, the server device 10 includes a control unit 11, a storage unit 12, and a communication unit 13.

[0039] The control unit 11 includes one or more processors. In one embodiment, the "processor" may be, but is not limited to, a general-purpose processor or a dedicated processor specialized for a specific process. The control unit 11 is communicably connected to each component of the server device 10 and controls the operation of the entire server device 10.

[0040] The storage unit 12 includes any storage module, such as a hard disk drive (HDD), a solid state drive (SSD), a read-only memory (ROM), and a random access memory (RAM). The storage unit 12 may function as, for example, a main storage device, an auxiliary storage device, or a cache memory. The storage unit 12 stores any information used in the operation of the server device 10. For example, the storage unit 12 may store system programs, application programs, and various data received from the control system 20 or the gas chromatograph 30. The storage unit 12 is not limited to being built into the server device 10, but may also be an external database or an external storage module.

[0041] The communication unit 13 includes any communication module that can communicate with other devices such as a scanner using any communication technology. The communication unit 13 may further include a communication control module for controlling communication with other devices, and a storage module for storing communication data such as identification information required for communication with other devices.

[0042] The functions of the server device 10 can be realized by executing a computer program (program) according to this embodiment on a processor included in the control unit 11. That is, the functions of the server device 10 can be realized by software. The computer program causes a computer to execute the processing of steps included in the operation of the server device 10, thereby causing the computer to realize the functions corresponding to the processing of each step. That is, the computer program is a program for causing a computer to function as the server device 10 according to this embodiment. The computer program may be recorded on a computer-readable recording medium. Programs include information used for processing by an electronic computer that is equivalent to a program. For example, data that is not a direct instruction to a computer but has properties that define computer processing falls under the category of "something equivalent to a program."

[0043] Some or all of the functions of the server device 10 may be realized by a dedicated circuit included in the control unit 11. That is, some or all of the functions of the server device 10 may be realized by hardware. Furthermore, the server device 10 may be realized by a single computer or by multiple computers working together.

[0044] (Control System) Fig. 3 is a block diagram showing an example of the configuration of the control system 20 in Fig. 1. As shown in Fig. 3, the control system 20 includes a control unit 21, a storage unit 22, a communication unit 23, and a measurement unit 24.

[0045] The hardware configurations of the control unit 21, the storage unit 22, and the communication unit 23 are similar to those of the control unit 11, the storage unit 12, and the communication unit 13 of the server device 10, and therefore detailed description thereof will be omitted.

[0046] The measuring unit 24 is a sensor that measures a physical quantity related to the device 50. For example, the measuring unit 24 may measure any physical quantity such as the temperature, pressure, and acceleration of an object to be measured.

[0047] The memory unit 22 of the control system 20 stores various data as second information. The various data are, for example, operation history and alarm data. The operation history as the second operation history is a history of operations related to the operation of the plant P acquired by the control system 20. For example, the operation history includes information such as valve operations and switch operations. The alarm data as the second alarm data is a history of alarms that have occurred in the plant P. For example, the alarm data includes information on abnormalities in the equipment 50, such as abnormal temperatures inside the tank. Note that the various data stored in the memory unit 22 may also include other information, such as physical quantities measured by the measurement unit 24.

[0048] As with the server device 10, some or all of the functions of the control system 20 may be implemented by software. Alternatively, some or all of the functions of the control system 20 may be implemented by a dedicated circuit included in the control unit 21. That is, some or all of the functions of the control system 20 may be implemented by hardware. Furthermore, the control system 20 may be implemented by a single device, or may be implemented by multiple devices working together.

[0049] (gas chromatograph) Fig. 4 is a block diagram showing an example of the configuration of the gas chromatograph 30 of Fig. 1. As shown in Fig. 4, the gas chromatograph 30 includes a control unit 31, a storage unit 32, a communication unit 33, and a measurement unit .

[0050] The hardware configurations of the control unit 31, the storage unit 32, and the communication unit 33 are similar to those of the control unit 11, the storage unit 12, and the communication unit 13 of the server device 10, and therefore detailed description thereof will be omitted.

[0051] The measurement unit 34 uses gas chromatography to measure the physical quantities of the gas flowing through the process line 60. Fig. 5 is a diagram showing an example of the configuration of the measurement unit 34 in Fig. 4. The measurement unit 34 includes a thermostatic bath 341, a sample valve 342, a column 343, and a detector 344.

[0052] The measurement unit 34 uses a sample valve 342 in a thermostatic bath 341 controlled to a constant temperature to collect a fixed amount of multi-component mixed gas flowing through the process line 60 as a process sample, and transports it to a column 343 using a carrier gas (mobile phase). The carrier gas is a gas that sends the process sample to the column 343, and steadily flows through the sample valve 342, column 343, and detector 344 in that order. The carrier gas is required to be stable and to have little effect as a background on the detector signal. For example, inorganic gases such as H2, He, N2, and Ar are used as carrier gases.

[0053] The gas to be measured is separated into individual components in column 343 and elutes in order. Each component in the multi-component gas to be measured, which has been transported to column 343 by the carrier gas, moves through column 343, repeatedly dissolving in and eluting from the stationary phase at a constant rate according to the partition coefficient specific to each component. The partition coefficient is the concentration ratio of the component of interest in the mobile phase and the stationary phase at equilibrium, and is calculated using the concentration in the mobile phase as the denominator. Since the migration speed differs depending on the partition coefficient, the process sample is gradually separated into individual components, and the components with the fastest migration speeds are sent out of column 343 in order.

[0054] The detector 344 converts the components eluted from the column 343 into electrical signals to obtain a chromatogram. The control unit 31 of the gas chromatograph 30 measures the physical quantity of the gas to be measured based on this chromatogram. For example, the control unit 31 may calculate the concentration from the peak area of ​​each component in the chromatogram. The gas to be measured, transported by the carrier gas, is discharged from a vent.

[0055] The memory unit 32 of the gas chromatograph 30 stores various data as first information, including the analysis data acquired by the above-described configuration. The various data include, for example, analysis data, operation history, alarm data, and device setting information of the gas chromatograph 30. The analysis data is information on the analysis results of the measurement target gas flowing through the process line 60. The operation history as the first operation history is a history of manual operations on the gas chromatograph 30. For example, the operation history includes information on parameter changes and calibration operations. The alarm data as the first alarm data is a history of alarms generated in the gas chromatograph 30. For example, the alarm data includes information on heater temperature abnormalities. The device setting information is setting information of devices required for measurement by the gas chromatograph 30. For example, the device setting information includes information on sequence settings and external signal settings. The various data stored in the memory unit 32 may also include other information, such as past chromatogram data and analysis values.

[0056] As with the server device 10, some or all of the functions of the gas chromatograph 30 may be implemented by software. Alternatively, some or all of the functions of the gas chromatograph 30 may be implemented by a dedicated circuit included in the control unit 31. That is, some or all of the functions of the gas chromatograph 30 may be implemented by hardware. Furthermore, the gas chromatograph 30 may be implemented by a single device or by multiple devices working together.

[0057] (Client device) Fig. 6 is a block diagram showing an example of the configuration of client device 40 in Fig. 1. As shown in Fig. 6, client device 40 includes a control unit 41, a storage unit 42, a communication unit 43, an input unit 44, and an output unit 45.

[0058] The hardware configurations of the control unit 41, the storage unit 42, and the communication unit 43 are similar to those of the control unit 11, the storage unit 12, and the communication unit 13 of the server device 10, and therefore detailed description thereof will be omitted.

[0059] The input unit 44 includes one or more input interfaces that accept a user's input operation and acquire input information based on the user's operation. For example, the input unit 14 is, but is not limited to, a physical key, a capacitance key, a pointing device, a touch screen that is integrated with the display (display unit) of the output unit 15, or a microphone that accepts voice input.

[0060] The output unit 15 includes one or more output interfaces that output information to the user and notify the user. For example, the output unit 15 is, but is not limited to, a display that outputs information as an image or a speaker that outputs information as sound. Such a display may be, for example, a liquid crystal panel display or an organic EL (Electro Luminescence) display. At least one of the input unit 14 and the output unit 15 may be configured integrally with the client device 40 or may be provided separately.

[0061] As with the server device 10, some or all of the functions of the client device 40 may be implemented by software. Alternatively, some or all of the functions of the client device 40 may be implemented by a dedicated circuit included in the control unit 41. That is, some or all of the functions of the client device 40 may be implemented by hardware. Furthermore, the client device 40 may be implemented by a single computer or by multiple computers working together.

[0062] (Example 1) Fig. 7 is a flowchart showing an operation example 1 of the server device 10 of Fig. 1. The operation of the server device 10 described with reference to Fig. 7 may correspond to one of the control methods of an information processing device. The operation of each step in Fig. 7 may be executed based on the control of the control unit 11 of the server device 10.

[0063] In step S1, the control unit 11 receives various data stored in the storage unit 22 from the control system 20. For example, the control unit 11 receives the above-mentioned operation history and alarm data as the various data.

[0064] In step S2, the control unit 11 receives various data stored in the memory unit 32 from the gas chromatograph 30. For example, the control unit 11 receives the analysis data, operation history, alarm data, and device setting information of the gas chromatograph 30.

[0065] The control unit 11 may perform the process of step S1 and the process of step S2 in reverse order. The control unit 11 may also perform the process of step S1 and the process of step S2 multiple times.

[0066] In step S3, the control unit 11 displays the various data of the control system 20 received in step S1 and the various data of the gas chromatograph 30 received in step S2. In this embodiment, the server device 10 transmits these data to the client device 40 and displays them on a display unit (display) of the output unit 45, but the data may also be displayed on another device, such as a display unit, provided in the server device 10.

[0067] Fig. 8 is a diagram showing an example of the configuration of a screen 100 displayed on the client device 40 of Fig. 1. Fig. 9 is a diagram showing an example of a screen actually displayed on the client device 40 of Fig. 1. As shown in Figs. 8 and 9, the screen 100 includes a plurality of areas 110 to 180 for displaying various data of the control system 20 and various data of the gas chromatograph 30.

[0068] The area 110 is a display area for the name of the measurement gas. The user can refer to the area 110 to confirm the measurement gas.

[0069] Area 120 is a display area for the operation history of control system 20. By referring to area 120, the user can check the operating status of plant P and confirm whether there has been any operation that may be causing an abnormality in gas chromatograph 30.

[0070] Area 130 is a display area for a list of warnings (alarms) of control system 20. By referring to area 130, the user can check whether there is any abnormality in the process line 60 for the measurement gas in control system 20.

[0071] Area 140 is a display area for the trends of various data measured in control system 20. The user can refer to area 140 to check the trends and determine whether there are any abnormalities that may be causing an alarm in gas chromatograph 30.

[0072] Area 150 is a display area for measurement data of gas chromatograph 30. A user can refer to area 150 to check the analysis results of the gas to be measured.

[0073] Area 160 is a display area for a list of alarms of the gas chromatograph 30. The user can refer to area 160 to check for abnormalities in the gas chromatograph 30.

[0074] Area 170 is a display area for the operation history of the gas chromatograph 30. The user can refer to area 170 to check whether there is an operation that may be causing an abnormality in the gas chromatograph 30.

[0075] Area 180 is a display area for a list of parameters of the gas chromatograph 30. The user can refer to area 180 to check whether there is an abnormality in the readings of the gas chromatograph 30. If there is an abnormality, the user can check whether there is a problem with the past configuration parameters.

[0076] In the example of FIG. 9 , area 160 displays “2022 / 11 / 15 10:31 C-COEF calibration coefficient abnormality” and “2022 / 11 / 15 10:22 CONC OUT concentration abnormality,” so the user recognizes that an abnormality has occurred in the calibration coefficient and concentration of gas chromatograph 30. The user then refers to areas 120 and 130 to check for information related to these abnormalities. In the example of FIG. 9 , area 120 displays “2022 / 11 / 15 8:10 Cracking furnace outlet valve OPEN,” “2022 / 11 / 15 7:10 Raw material feed valve OPEN,” and “2022 / 11 / 15 6:30 Raw material feed valve OPEN.” By referring to area 120, the user can recognize that the operations indicated in area 120 were performed prior to the date and time when the abnormality in gas chromatograph 30 was detected. Area 130 displays "2022 / 11 / 15 10:31 Cracking Furnace No. 3 Temperature Abnormal," "2022 / 11 / 15 10:22 Cracking Furnace Outlet Temperature Abnormal," and "2022 / 11 / 15 9:10 Cracking Furnace Oxygen Concentration Abnormal." By referring to area 130, the user can recognize that an abnormality in the cracking furnace temperature and oxygen concentration occurred on the same date and time as the abnormality was detected in gas chromatograph 30. Area 140 displays graphs showing trends of various data acquired by control system 20. By referring to area 140, the user can check whether there were any events related to the alarm of gas chromatograph 30. The user can also refer to the information in areas 150, 170, and 180 to confirm the cause of the abnormality in gas chromatograph 30 in detail.

[0077] When the control unit 11 finishes the process of step S3, it ends the process of the flowchart in FIG.

[0078] As described above, the server device 10 acquires first information acquired by the gas chromatograph 30 that analyzes a measurement target gas by gas chromatography in the plant P. The server device 10 acquires second information, which is information about the gas chromatograph 30, acquired by the control system 20 that controls the equipment 50 that constitutes the plant P. The server device 10 displays the screen 100 including the acquired first information and the acquired second information on the display unit (output unit 45). In this manner, the server device 10 displays the screen 100 including not only the first information acquired by the gas chromatograph 30 but also the second information, which is information about the gas chromatograph 30 acquired by the control system 20. Therefore, the user can acquire multifaceted information about an abnormality in the gas chromatograph 30 by referring to the first information and the second information, and can appropriately perform necessary maintenance and inspection.

[0079] The server device 10 may acquire at least one of the analysis data, operation history, alarm data, and device setting information acquired from the gas chromatograph 30 as the first information and display it on the display unit, allowing the user to perform a detailed inspection using this information.

[0080] Furthermore, the server device 10 may acquire at least one of a second operation history, which is a history of operations related to the operation of the plant P, and second alarm data, which is a history of alarms that have occurred in the plant P, as second information and display it on the display unit. Therefore, the user can use this information to perform a detailed inspection.

[0081] The server device 10 may further include a communication unit 13 for communicating with the client device 40. The server device 10 may transmit the first information and the second information to the client device 40 via the communication unit 13, and cause a screen 100 including the first information and the second information to be displayed on a display device (output unit 45) included in the client device 40. In this way, the server device 10 causes the client device 40 to display the screen 100 including the first information and the second information, so that the user can remotely perform maintenance and inspection of the chromatograph via the client device 40.

[0082] (Example 2) Fig. 10 is a flowchart showing a second operation example of the server device 10 in Fig. 1. The operation of the server device 10 described with reference to Fig. 10 may correspond to one method of controlling an information processing device. The operation of each step in Fig. 10 may be executed based on the control of the control unit 11 of the server device 10.

[0083] In step S11, the control unit 11 acquires information about the operating environment of the gas chromatograph 30. For example, the control unit 11 receives information including the measurement gas flow rate and the column replacement timing for each target gas chromatograph, target measurement flow path, and measurement gas temperature from the gas chromatograph 30. The control unit 11 may acquire this information by reading it from the storage unit 12, which has been stored in advance in the storage unit 12.

[0084] In step S12, the control unit 11 acquires the replacement cycles of parts such as the column 343 of the gas chromatograph 30 used in the usage environment indicated by the information acquired in step S11.

[0085] In step S13, the control unit 11 creates a prediction model for predicting the replacement period of the parts from the usage environment of the gas chromatograph 30 based on the information about the usage environment acquired in step S11 and the replacement period of the parts of the gas chromatograph 30.

[0086] For example, the control unit 11 may create a prediction model for the replacement period of parts of the gas chromatograph 30 by multiple regression analysis using a plurality of pieces of information about the usage environment of the gas chromatograph 30 as explanatory variables and the replacement period as an objective function. The control unit 11 may also allow the user to set the weight of the explanatory variables. Specifically, the control unit 11 may n , target measurement flow path C n , and the measurement gas temperature Y n A prediction model for predicting the column replacement period may be created by performing weighted multiple regression analysis using the measurement gas flow rate a1, column replacement timing a2, and column replacement period a3 as explanatory variables, as shown in Equation (1). Here, n is a natural number (n=1, 2, 3, . . . ) that identifies the gas chromatograph 30. For example, if the management system 1 is equipped with k gas chromatographs 30, n=1, 2, 3, . . . , k.

[0087] S(Dn,Cn,Yn)=p1a1+p2a2+p3a3(1)

[0088] In formula (1), S is the gas chromatograph D n p1, p2, and p3 are learning data relating to the replacement cycles of parts in the vehicle. p1, p2, and p3 are parameters for weighting in multiple regression analysis. The control unit 11 may accept changes to the settings of the parameters p1, p2, and p3 from the user when creating a prediction model.

[0089] Furthermore, the control unit 11 may perform a regression analysis of S for each part based on the formula (2) to create a prediction model.

[0091] In the formula (2), f is learning data regarding the replacement period of parts for all gas chromatographs 30. n are parameters for performing regression analysis for each part. When creating a prediction model, the control unit 11 receives the parameters P n You may also accept changes to the settings.

[0092] The control unit 11 may create a prediction model for predicting the replacement cycle of parts using any machine learning method other than multiple regression analysis.

[0093] After completing the process of step S13, the control unit 11 ends the process of the flowchart of FIG.

[0094] (Example 3) Fig. 11 is a flowchart showing a third operation example of the server device 10 in Fig. 1. The operation of the server device 10 described with reference to Fig. 11 may correspond to one of the control methods of an information processing device. The operation of each step in Fig. 10 may be executed based on the control of the control unit 11 of the server device 10.

[0095] In step S21, the control unit 11 acquires information about the operating environment of the gas chromatograph 30. For example, the control unit 11 receives information including the measurement gas flow rate and the column replacement timing for each target gas chromatograph, target measurement flow path, and measurement gas temperature from at least one of the gas chromatograph 30 and the control system 20. The control unit 21 may acquire this information by reading it from the storage unit 12, which has been stored in advance in the storage unit 12.

[0096] In step S22, the control unit 11 predicts the replacement period of parts such as the column 343 of the gas chromatograph 30 based on the information acquired in step S21, using a prediction model previously learned based on the flow of FIG.

[0097] In step S23, control unit 11 notifies the user of the part replacement cycle predicted in step S22. For example, control unit 11 may transmit the part replacement cycle to client device 40 and cause the display unit of output unit 45 of client device 40 to display it. Alternatively, control unit 11 may cause another device, such as a display unit included in server device 10, to display the part replacement cycle. Upon completing the processing of step S23, control unit 11 ends the processing of the flowchart in FIG. 11.

[0098] As described above, the server device 10 may acquire environmental information indicating the environment related to the usage environment of the gas chromatograph 30. The server device 10 may predict the replacement period of the parts of the gas chromatograph 30 based on the environmental information using a prediction model trained in advance with the usage environment of the gas chromatograph 30 as an explanatory variable and the replacement period of the parts (e.g., the column 343) of the gas chromatograph 30 as a target variable. The server device 10 may display the predicted replacement period of the parts on a display unit (e.g., a display device of the output unit 45 of the client device 40). In this way, the server device 10 uses the trained prediction model to predict and display the replacement period of the parts based on the usage environment of the gas chromatograph 30. This allows the user to know the appropriate time to replace parts in a timely manner without having to perform complicated part management.

[0099] Furthermore, the server device 10 may predict the replacement period based on the environmental information by using a model previously trained by weighted multiple regression analysis in which weights are set by the user as a prediction model, with the usage environment of the gas chromatograph 30 as an explanatory variable and the replacement period of the parts of the gas chromatograph 30 as a target variable. In this way, the server device 10 predicts the replacement period of the parts using a model previously trained by weighted multiple regression analysis in which weights are set by the user, and therefore it is possible to predict the replacement period of the parts using a prediction model that reflects the user's intentions.

[0100] Furthermore, the server device 10 may generate a prediction model by learning information indicating the usage environment of the gas chromatograph 30, obtained from at least one of the gas chromatograph 30 and the control system 20, as explanatory variables, and the replacement cycle of the parts of the gas chromatograph 30 as objective variables. In this way, the server device 10 generates a prediction model using information obtained from at least one of the gas chromatograph 30 and the control system 20, and therefore can accurately predict the replacement cycle of the parts by reflecting the actual usage conditions of the gas chromatograph 30 and the control system 20.
