Description

  The present invention relates to a training learning support apparatus that supports learning of an operator in a plant operation training system that performs plant operation training using a plant simulator.

  Since many large-scale plants are complicated in operation, the learning period for new operators to acquire plant operation is set to be very long. In addition to the classroom learning method using lectures and manuals, there are cases where practical learning methods such as simulated driving are used as plant learning methods.

  When performing simulated operation, training using an actual plant cannot be performed from the viewpoint of plant safety and cost. Therefore, generally, training using a plant simulator is performed instead of an actual plant.

  A plant simulator simulates the behavior of an actual plant on a computer. By using the same monitoring operation screen interface as that of the actual plant, the user can experience the same monitoring control operation as that of the actual plant.

  Usually, practical training using a plant simulator is performed by a team of instructors and trainees. The instructor inputs the plant state such as an accident event into the simulator and starts the simulation. The trainee performs a corresponding operation similar to that performed on the actual plant based on the information displayed on the simulator, and the instructor observes the operation of the trainee. The training is completed after confirming that the plant has shifted to a predetermined state, and the lecturer reviews and gives guidance to the trainee. The trainees deepen their understanding of the work by repeating questions and answers about the contents of judgment criteria and response operations in each situation with the instructor.

  In this way, by performing training using the plant simulator, the trainee can easily learn a method for responding to an event that has a low frequency of occurrence such as a plant accident but has a large effect. In addition, by reproducing the same plant situation, it is possible to carry out repeated practice and enhance the learning effect.

  However, the instructor must always check the plant parameters and the like during practical training, and check the operation and confirmation contents of the trainee while judging what state the plant is currently in. Therefore, the workload of the instructor is high, there is a possibility that the behavior of the trainee may be overlooked, and the evaluation contents vary.

  In order to deal with such problems, Patent Document 1 proposes a method in which a computer evaluates training instead of a lecturer. According to the method of Patent Document 1, by setting an evaluation point in the plant parameter in advance, the operator's operation content can be evaluated by the computer, the load on the instructor can be suppressed, and the evaluation criteria can be leveled. There are advantages.

  Further, in Patent Document 2, a method of calculating operation contents for realizing a plant parameter target value by simulating a behavior inside a target plant by an arithmetic expression and inputting a target value of a plant parameter into the arithmetic expression. Has been proposed. According to the method of Patent Document 2, the operation guidance and the reason thereof can be created by using the data of the calculation process.

Japanese Patent No. 2610345 Japanese Patent No. 3783418

  The purpose of practical training using the plant simulator is not only to measure the trainee's proficiency in plant operation. The purpose is to remind the trainees themselves of new questions and challenges that could not be understood only through classroom learning by experiencing a situation close to the real environment. On the other hand, in the method of Patent Document 1, when a trainee performs practical skill training alone, even if the trainee's plant operation content can be evaluated, how to achieve the plant state desired by the trainee You can't give an answer as to what to do.

  Patent Document 2 is intended for a plant in which the behavior inside the plant is expressed by a relatively simple model, and an arithmetic expression that takes a plant parameter target value as an input and outputs a recommended plant setting value as an output can be defined. That is, the target is limited when the operation method for controlling the plant parameters is uniquely determined. However, in a system where the internal behavior is complex and a single operation affects various plant parameters as in a large-scale plant, the operation method for realizing the target plant state consists of a combination of multiple operations. There are several ways. In addition, since it is necessary to consider the influence of the input operation on other parameters, an arithmetic expression that outputs the recommended plant setting value cannot be uniquely defined, and the technique of Patent Document 2 cannot be used.

  In view of the above-described problems, the present invention is to provide a training learning support device that increases the learning efficiency of trainees in a plant operation training system using a plant simulator.

  The training learning support device of the present invention is a training learning support device for supporting learning of operation training in a plant operation training system for performing plant operation training, and the plant operation training system is configured to perform computation on a computer. A plant simulator for simulating plant behavior and a parameter input device for inputting initial values of parameters used in the plant simulator to the plant simulator. The training learning support device is selected as a control target from among the parameters used in the plant simulator. A target value input means for inputting target information including specific information of the selected control parameter, a target value of the control parameter, and a time to reach the target value by a user operation, and an operation sequence of the plant simulator, An operation list including operation items and operation targets for each operation. An operation list input means that inputs user operations that affect control parameters, and a recommended operation creation means that determines recommended operation contents in simulation on a plant simulator based on a comparison between control parameters and target information Display means for displaying the recommended operation content, and the recommended operation creating means operates by adding operation information including operation parameters related to the operation amount of each operation in the operation list and the operation amount of each operation to the operation list. Operation content determination means for creating contents and inputting the operation contents to the plant simulator, and operation result evaluation means for receiving control parameter transition information from the plant simulator and calculating the evaluation degree by comparing the transition information with target information The operation content determination means has a high evaluation degree by mathematical programming until a predetermined determination condition is satisfied. Consisting direction change operation information, the recommended operation content operation content when the predetermined determination condition is satisfied.

A plant simulator for simulating plant behavior and a parameter input device for inputting initial values of parameters used in the plant simulator to the plant simulator. The training learning support device is selected as a control target from among the parameters used in the plant simulator.

Operation content determination means for creating contents and inputting the operation contents to the plant simulator, and operation result evaluation means for receiving control parameter transition information from the plant simulator and calculating the evaluation degree by comparing the transition information with target information The operation content determination means has a high evaluation degree by mathematical programming until a predetermined determination condition is satisfied. The operation information is changed in the direction of the above and the operation content when the predetermined judgment condition is satisfied is set as the recommended operation content. Therefore, the plant operation method cannot be obtained with a single arithmetic expression. However, the user can grasp the operation content necessary for realizing the target plant state, and the training learning support apparatus with high learning efficiency is obtained.

<A. Embodiment 1>
<A-1. Configuration, operation>
This apparatus is a training learning support apparatus that is assumed to be used for performing self-evaluation and review after a user performs an operation training using a plant simulator. The user who has performed the operation training needs to examine what kind of operation can realize the ideal plant behavior when a part judged to be undesirable is found through self-evaluation of the operation content. is there.

  This device inputs a plant behavior desired by the user and automatically formulates an operation (recommended operation content) necessary for realizing the input plant behavior.

  FIG. 1 is a block diagram showing the configuration of the plant operation training system according to Embodiment 1 of the present invention. The plant operation training system includes a plant simulator 100 that simulates plant behavior, a parameter input device 200 that inputs initial values of various plant parameters used in the plant simulator 100, and a training learning support device 300. Prepare. The training and learning support apparatus 300 can be realized on a computer, like the plant simulator 100.

  The training learning support apparatus 300 includes recommended operation creation means 310, target value input means 320, operation list input means 330, and display means 340.

  The target value input means 320 is for the user to specify a control parameter to be controlled from plant parameters and to input the target information. Here, the target information includes the target value of the control parameter and the time to reach the target value (target time). In addition to the format for setting the upper and lower limits of control parameters, the target information is automatically based on control parameter values such as the target value for each unit time, such as a trend graph, and alarm generation and system automatic control. It is set in a format that sets the startup time of the system to be started. In this way, the plant behavior targeted by the user is input from the target value input means 320.

  The operation list input unit 330 is an operation list input unit that is simulated by the plant simulator 100. Here, the operation list shows the order of multiple operations. For each operation in the operation list, the user sets the operation type such as screen transition, input operation, confirmation of control parameter value, etc. Specify the item to be operated.

  The recommended operation creating unit 310 is a unit that formulates a driving operation recommended for achieving the target information of the control parameter set by the user using the target value input unit 320. The recommended operation creating unit 310, the operation result evaluating unit, and the like. 312 and a recommended operation database 313.

  The operation content determination unit 311 adds operation information to the operation list set by the operation list input unit 330 and creates the operation content. Here, the operation information includes the operation timing of each operation (elapsed time from the start of simulation) and operation parameters related to the operation amount.

  The plant simulator 100 receives the operation content created by the operation content determination means 311 and starts the simulation calculation using the initial parameter value input by the parameter input device 200. Operation input is performed according to the execution timing and operation parameters set by the operation content determination unit 311, and control parameter transition information obtained by the calculation is transmitted to the operation result evaluation unit 312.

  The operation result evaluation means 312 compares the control parameter transition information sent from the plant simulator 100 with the target of the plant parameter given from the target value input means 320, and calculates the degree of achievement of the target as an evaluation value.

  The recommended operation database 313 includes the operation content determined by the operation content determination unit 311, the transition information of the control parameter calculated by the plant simulator 100 by inputting the operation content, and the evaluation value calculated by the operation result evaluation unit 312. The combined information is accumulated.

  The operation content determination unit 311 acquires the evaluation value calculated by the operation result evaluation unit 312 and sets the operation information, that is, the execution timing of each operation procedure and the operation parameter so that the evaluation value becomes high. Change using the law. That is, when the operation content determination unit 311 changes the operation information, the plant simulator 100 performs the simulation again based on the new operation information. The transition result of the control parameter is evaluated by the operation result evaluation unit 312 and the set value control input value is further changed based on the evaluation value. These steps are repeatedly performed, and are ended according to a determination condition such as an elapsed time from the start of calculation or a predetermined number of solutions satisfying the target, and the operation content when the determination condition is satisfied becomes the recommended operation content.

  Note that the combination of operation contents, control parameter time transition information, and evaluation values in this repetitive process is stored in the recommended operation database 313 as needed. The determined recommended operation content is displayed on the display means 340. In addition, when the operation content which implement | achieves a target is not calculated | required, the solution nearest to a target may be made into a recommended operation content, or you may display without an applicable solution.

<A-2. Training result display>
FIG. 2 schematically shows a training result display screen displayed by the display means 340. The training result display screen displays operation details, alarms, and parameter values. The operation content display is displayed when the recommended operation creation unit 311 has formulated the recommended operation content that satisfies the target, and the individual operation content indicating what operation has been performed is displayed in time series. FIG. 2 shows that the operation device A operation, the operation device B operation, the operation device B operation, and the operation device C operation are sequentially performed. The operation parameters may be displayed together.

  In the alarm display in the lower part of the operation content display, the individual alarm content indicating which alarm has occurred is displayed in the same time series as the operation content display. FIG. 2 shows that the alarm A is generated after the first operation of the operation device B and the alarm B is generated after the second operation of the operation device B. In the case of a plant operation training system in which an alarm is automatically generated in relation to the value of the control parameter, the alarm can be displayed based on the control parameter transition information. The alarm convergence time may be displayed so as to be visually understood.

  Further, parameter values are displayed in the lower part of the alarm display. In FIG. 2, trends of two types of control parameter values are displayed.

  These three types of screen display items on the training result display screen are displayed side by side in the same direction, and the axes in the time direction are displayed so as to have the same step size. It is possible to confirm how the alarm generation status has changed. Thereby, the user can grasp the operation content for achieving the target input by the target value input means 320.

  In addition, the user can change the target information of the control parameter by changing or deleting the position of the individual contents of the alarm display or changing the shape of the trend graph of the parameter value display on the training result display screen. is there. That is, the display unit 340 functions as an input interface for the target value input unit 320.

  For example, when the individual alarm content indicating the occurrence of the alarm A is deleted from the training result display screen, the recommended operation creating unit 311 is optimal with the goal of causing the plant parameters related to the alarm A to transition so as not to generate the alarm A. The recommended operation content is created, and the result is reflected in the operation content display on the training result display screen. In this way, the user can examine the operation content that suppresses the occurrence of the alarm.

  Similarly, when the shape of the trend graph in the parameter value display is changed from the training result display screen, the recommended operation content for realizing the trend of the changed control parameter is reflected in the operation content display. In this way, the user can examine the operation content for realizing the desired trend change of the plant parameter.

The training learning support device 300 includes a plant simulator. 100, target value input means 320 for inputting target information including specific information of a control parameter selected as a control target from among parameters used in 100, a target value of the control parameter, and a time to reach the target value by a user operation. And operation of the plant simulator 100 An operation list that includes an operation item and an operation target for each operation and that has an influence on the control parameter is input by a user operation, and a comparison between the control parameter and the target information The recommended operation creating means 310 for determining the recommended operation contents in the simulation on the plant simulator 100 and the display means 340 for displaying the recommended operation contents are provided. The recommended operation creating means 310 includes each of the operation lists in the operation list. Operation content determination means 311 for creating operation contents by adding operation information including operation parameters related to operation time and operation amount of each operation to the operation list, and inputting the operation contents to the plant simulator 100, and a plant simulator The control parameter transition information is received from 100, and the transition information is compared with the target information to evaluate An operation result evaluation unit 311 for calculating, and the operation content determination unit 311 changes the operation information in a direction in which the degree of evaluation is increased by mathematical programming until a predetermined determination condition is satisfied, and the predetermined determination condition is set. The content of the operation when it is satisfied is the recommended content of operation. Since the training and learning support apparatus 300 is configured in this way, the user realizes the target plant state even if the plant has a complicated behavior in which the plant operation method cannot be obtained with a single arithmetic expression. Therefore, the recommended operation content can be grasped, and the plant operation training can be performed efficiently.

  In the training learning support apparatus according to Embodiment 1, the display unit 340 displays the recommended operation content and the transition information of the control parameter corresponding to the recommended operation content in time series, and displays the parameter transition information on the display screen. By changing, it also functions as an input interface of the target value input means 320 capable of inputting target information. When the control parameter transition information is changed on the display screen, the operation content for realizing the changed control parameter transition information is displayed, so that the user can efficiently perform plant operation training.

<B. Second Embodiment>
<B-1. Configuration, operation>
In general, even if the same plant operation is performed, it is considered that a new operator may take longer to operate than an experienced operator. For this reason, if recommended operation content with an extremely short interval between operations is set, it may be difficult for a new operator to perform the operation as it is. Therefore, the training learning support apparatus in the plant operation training system according to the second embodiment solves the above-described problem by providing a function for adjusting the operation interval before and after the operation content according to the user type.

  FIG. 3 is a block diagram showing the configuration of the plant operation training system according to the second embodiment. In FIG. 3, the same components as those in the first embodiment are denoted by the same reference numerals. The training learning support apparatus 301 according to the second embodiment includes a human behavior model database 350 in addition to the configuration of the training learning support apparatus 300 according to the first embodiment. The other configuration is the same as that of the training learning support apparatus 300 of the first embodiment.

  In the human behavior model database 350, the time required for basic operations such as screen selection and value confirmation is registered for each user type such as an experienced operator or a new operator. Alternatively, in addition to directly registering the required time, the required time may be registered indirectly by an arithmetic expression for calculating the required time using the movement distance of the mouse cursor as a variable.

  The operation content determination means 311 uses the required time registered in the human behavior model database 350 as a constraint condition for the operation interval. For example, it is assumed that a new operator is operating and an input operation of a predetermined parameter is included in the operation list. The operation content determination unit 311 acquires the time required for the input operation by the new operator from the human behavior model database 350, and the interval from the input operation to the next operation is the required time acquired from the human behavior model database 350. The execution timing of each operation is determined so as not to be shorter.

  The training learning support apparatus 301 is configured such that the user can input his / her user type from other input means such as the target value input means 320, for example.

<B-2. Effect>
The training learning support apparatus according to Embodiment 2 includes a human behavior model database 350 that stores a time required for a predetermined basic operation related to a plant operation operation as a required time for each user type, and the operation content determination unit 311 includes an operation list. Since at least the required time according to the user type is provided between each operation and the execution time of each operation is determined, for example, a very short operation interval is set, for example, from the viewpoint of a human behavior model, Operation contents that cannot be operated are not set.

<C. Embodiment 3>
<C-1. Configuration, operation>
Operation training using a plant simulator may not only be completed within a few minutes from the start of training, but may require several tens of minutes. When only the last part of a series of operation lists that take a long time is changed, repeating the simulation from the beginning of the operation list leads to a long simulation time and is inefficient. Therefore, in the plant operation training system according to the third embodiment, the changed part of the operation list is specified, and the simulation is performed from the changed part.

  FIG. 4 is a block diagram illustrating a configuration of a plant operation training system according to the third embodiment. In FIG. 4, the same reference numerals are given to the same components as those in the first embodiment. The plant operation training system according to the third embodiment includes a plant simulator 100, a parameter input device 200, and a training learning support device 302.

  The training learning support apparatus 302 according to the third embodiment includes a plant parameter database 360 and parameter selection means 370 in addition to the configuration of the training learning support apparatus 300 according to the first embodiment. In the plant parameter database 360, the recommended operation content created so far and the transition information for each unit time of the control parameter as the simulation result are stored in association with each other.

  When the parameter selection unit 370 receives an operation list (hereinafter also referred to as an input operation list) input by the user from the operation list input unit 330, the parameter selection unit 370 registers the input operation list and the plant parameter database 360 using a pattern matching method or the like. The operation list (hereinafter also referred to as a registered operation list) of each recommended operation content (hereinafter also referred to as a registered operation content) is compared. If there is a registered operation list in which only some operations are different from the input operation list, the different portion of the input operation list is set as the simulation range.

  Next, the parameter selection means 370 transmits the value of the control parameter corresponding to the first operation time of the different part of the registered operation list to the plant simulator 100 as an initial parameter. In addition, the simulation range of the input operation list is transmitted to the recommended operation creation unit 310.

  The operation content determination unit 312 creates an operation content by adding the operation execution time and operation parameters for the simulation range of the input operation list received from the parameter selection unit 370 and outputs the operation content to the plant simulator 100.

  In the plant simulator 100, the operation content set by the operation content determination unit 312 is simulated using the initial parameters received from the parameter selection unit 370. Other operations are the same as those in the training learning support apparatus 300 of the first embodiment, and the recommended operation content is determined by changing the operation content in the simulation range by a mathematical programming method such as a combinational optimal method.

  The display unit 340 extracts the recommended operation content created by the recommended operation creating unit 310 from the recommended operation database 313 for the simulation range in the input operation list, and the registered operation content from the plant parameter database 360 for other than the simulation range. Extract and combine them and output to the display screen.

  If there is no registered operation list that partially matches the input operation list, similar to the first embodiment, a simulation is performed for all of the input operation lists to determine the operation content. In this case, the plant simulator 100 starts the simulation using the parameter initial value input from the parameter input device 200.

  In the training learning support apparatus 302 according to the second embodiment, when the input operation list is a part of the registered operation list, the changed part is set as a simulation range, and simulation is performed only for the simulation range. The recommended operation content can be determined in a shorter time than when the simulation is performed for the entire input operation list.

  When a certain operation affects subsequent operations, the simulation range may be set including not only the changed portion of the input operation list with respect to the registered operation list but also the subsequent input operation lists.

<C-2. Effect>
The training learning support apparatus according to the third embodiment inputs a plant parameter database 360 that stores past recommended operation contents in the plant simulator 100 and transition information for each unit time of control parameters in association with each other and an operation list input unit. The operation list in the recommended operation content stored in the plant parameter database 360 is compared, and if some of these are different, the control parameter at the first time of the different part is obtained from the plant parameter database 360. A parameter selection unit 370 that extracts and sets the control parameter initial value 370 and sets it instead of the parameter input device 200, and the recommended operation creation unit 310 includes a different part of the operation list input to the operation list input unit 330. Create recommended actions for When changing a part of the operation list for which the operation content has already been created, only the operation list after the changed part is simulated to create the operation content, so the operation content is re-created for all operation lists. The processing time can be shortened compared to

<D. Embodiment 4>
<D-1. Configuration, operation>
In the plant operation training system according to the first to third embodiments, in creating the recommended operation content that realizes the target of the control parameter, the user grasps the procedure of the corresponding operation for the event that has occurred in the plant simulator 100, It is assumed that you enter the operation list yourself. However, even if the user who does not understand the corresponding operation itself for the occurrence event can input an ideal control parameter change from the target value input unit 320, the user cannot input the operation list from the operation list input unit 330. . Therefore, in the plant operation training system of the fourth embodiment, the recommended operation content for realizing the target of the control parameter is created without requiring the user to input an operation list.

  FIG. 5 is a block diagram showing a configuration of a plant operation training system according to the fourth embodiment. In FIG. 5, the same components as those in the first to third embodiments are denoted by the same reference numerals. The plant operation training system according to the fourth embodiment includes a plant simulator 100, a parameter input device 200, and a training learning support device 303.

  The training learning support apparatus 303 according to the fourth embodiment includes a parameter-operator database 380 and a plant event related operation list database 390 in addition to the configuration of the training learning support apparatus 302 according to the third embodiment. An operation list creating means 331 is provided instead of the means 330. The operation list input unit 330 and the operation list creation unit 331 may be used in combination.

  In the parameter-operation device database 380, each plant parameter and an operation device effective for the control are associated and registered. Since the influence of each operation device affects various parameters in the plant, the relationship between the plant parameter and the operation device is not limited to one-to-one, and there are cases where the relationship is many-to-many. Also, the change direction (large or small) of the print parameter corresponding to the operation direction of the operation device is also registered.

  In the plant event-related operation list database 390, a unique identifier determined for each plant event and an operation list corresponding to the unique identifier are registered. The corresponding operation list indicates an order of a plurality of operations corresponding to the plant event, and for each operation, an operation target is specified in addition to an operation type such as screen transition, input operation, or control parameter value confirmation.

  Various events reproduced by the plant simulator 100 are registered in the plant simulator 100 as internal variables together with unique identifiers. The operation list creation unit 331 acquires a unique identifier of a plant event from the plant simulator 100, refers to the plant event related operation list database 390, and selects a corresponding operation list of the plant event.

  The operation list creating unit 331 receives control parameters designated by the user as a control target from the target value input unit 320, refers to the parameter-operator database 380, and information on the operation devices effective for controlling the control parameters. To extract.

  Next, the operation device information described in the corresponding operation list selected from the aforementioned plant event-related operation list database 390 is compared with the operation device information extracted from the parameter-operation device database 380, and recommended from the corresponding operation list. Extract the operations required to create an operation and create a new operation list.

  After that, as in the third embodiment, the recommended operation content for achieving the control parameter target input by the user by adding the operation information to the operation list created by the recommended operation creation unit 310 by the recommended operation creation unit 331. And the recommended operation content is displayed on the display means 340.

  According to the training learning support apparatus 303 of the fourth embodiment, even when the user forgets the corresponding operation or inputs an incorrect operation, the necessary part is extracted from the corresponding operation list registered in the database. Can create an operation list and review the recommended operations.

<D-2. Effect>
The training and learning support apparatus according to Embodiment 4 includes a parameter-operator database 380 that stores an operator that affects plant parameters in association with the plant parameter, and a plant event that stores an operation list corresponding to each plant event. And a related operation list database 390. The operation list corresponding to the current plant event is acquired from the plant event related operation list database 390 instead of the operation list input means 330, and the parameter-operation is included in the operation list. The operation list creation unit 331 extracts an operation list associated with the operation unit corresponding to the control parameter from the device database 380 and sets it as a new operation list. The recommended operation creation unit 310 is created by the operation list creation unit 331. Recommended operation by adding operation information to the selected operation list To create a volume. Because of such a configuration, even a user who does not know the corresponding operation of the event that has occurred in the plant simulator 100 can examine the recommended operation content by inputting the ideal state of the control parameter.

<E-1. Configuration, operation>
FIG. 6 is a block diagram showing the configuration of the training learning support apparatus according to the fifth embodiment.

  In the training learning support devices of the first to fourth embodiments, the user can arbitrarily set the plant parameter target value from the target value input means 320, but there is a situation that there is no feasible solution depending on the set value. Can occur. In such a case, in the solution search process, the time is greatly detoured and the time is increased, but the accuracy of the output solution is low, which may reduce the efficiency of driving training.

  In the case of a user who has abundant plant operation experience, it is possible to appropriately give a target value. However, in the case of a user who has little operation experience, it is not known to what extent the target value is allowed. Therefore, the training learning support apparatus according to the fifth embodiment includes controllable range calculation means 220 that infers a controllable range that can be taken by a selected parameter when an arbitrary parameter is selected in an arbitrary plant state. It was.

  The controllable range calculation unit 220 uses the control parameter selected by the target value input unit 320 and the operation list input from the operation list input unit 330, and performs a simulation using the plant simulator 100, so that the parameter is obtained. The controllable range that can be taken, for example, the upper and lower limits are estimated. The controllable range calculation unit 220 extracts an effective operation for controlling the control parameter from the operation list input from the operation list input unit 330, and determines the execution timing of the extracted operation and the operation parameter. While changing, referring to the simulation result of the plant simulator 100, the controllable range of the control parameter, for example, the upper and lower limit values is estimated.

  The recommended operation creating unit 310 creates the operation contents only when the target value of the parameter input by the user to the target value input unit 320 is within the controllable range. When a target value outside the controllable range is input to the target value input unit 320, for example, the display unit 340 displays the controllable range of the control parameter and prompts the user to input an appropriate target value. good.

<E-2. Effect>
The training learning support apparatus according to the fifth embodiment creates an operation content in which operation information is added to the plant simulator 100 for a predetermined operation in the operation list received from the operation list input unit 330 or the operation list creation unit 331. It further includes controllable range calculation means 400 that calculates the controllable range of the control parameter while inputting and changing the operation information using mathematical programming. When the target value of the control parameter is out of the controllable range, the recommended operation creating unit 310 does not create the recommended operation content of the operation list, so that it is possible to avoid spending time on searching for an infeasible solution.

  It should be noted that the present invention can be freely combined with each other within the scope of the invention, and each embodiment can be appropriately modified or omitted.
