Description

  The present invention relates to an operation plan server and an operation plan system, and more particularly to a technology related to an operation plan of a system in which a plurality of facilities cooperate.

  As represented by water operation, in a large-scale system in which a plurality of facilities and equipment are linked, it is common to formulate an operation plan for a predetermined period in advance with the support of a computer system. While environmental issues are attracting attention, not only the operational efficiency of each facility and equipment, but also the optimal operation plan for the entire system is required more than ever by linking facilities and equipment.

  There are several requirements to consider when planning an operation plan. These include requests for stable operation of facilities such as restrictions on the upper and lower limits of pipelines and reservoirs, fluctuations in the flow rate of pipelines, and demands for reducing environmental impact. The reduction of environmental load in facility operation can also be divided into specific requests such as energy saving and reduction of sludge generated at water treatment plants. Such an operation plan having a plurality of requests is often formulated as a multi-purpose optimization problem.

  In general, since multiple requests are in a trade-off relationship with each other, it is impossible to pursue all requests at the same time. Therefore, it is necessary to balance the achievement of each request when making an operation plan.

  In trade-off adjustment, the planner sets the input items for the computer system and confirms the operation plan obtained as a result of the calculation. Do. Since it is not easy to set the input items to obtain the desired operation plan, this process is a trial and error process until a satisfactory operation plan is obtained.

  In the technique described in Patent Literature 1, a plurality of operation plans are prepared in advance and presented to the operator, and the operator inputs an order to the operation plans as an input item. In a multi-objective optimization problem, a weighting factor is generally used as an input item for adding a plurality of objectives to unify them. Rather than directly setting the weighting factor, an appropriate weighting factor is calculated from the ordering of the presented operation plans.

  In the technique described in Patent Document 2, an object is a color processing system that adjusts the color reproduction of an image, an adjustment process history is stored, and the history is displayed to the operator to adjust at an arbitrary time point. The operation is reproducible.

JP 2006-48212 A JP 2007-36881 A

  According to Patent Document 1, the input item to the system can be an item of ordering of the presented operation plans.

  However, if the operation plan obtained by a certain ordering is not a plan desirable for the operator and it is desired to further adjust, it is not always clear how to change the ordering to obtain a plan more desirable for the operator. As a result, trial and error of ordering is repeated, and problems remain in practice.

  According to Patent Literature 2, a trade-off adjustment process can be reproduced.

  However, the technique described in Patent Document 2 relates to a general image processing technique and is not applied to an operation plan. Even if it is applied, it is not easy to compare plans because there are many items in operation plans for many facilities and equipment. Therefore, the technique described in Patent Document 2 does not lead to improvement in operability.

  Further, in the trade-off adjustment, it is difficult to determine at which point the search is terminated and the obtained operation plan can be determined as a satisfactory operation plan. Of course, it is the operator who makes the judgment by trade-off adjustment, but there is a problem of how to assist the judgment as a computer system.

  An object of the present invention is to provide an operation plan server and an operation plan system that can quickly adjust trade-offs when preparing an operation plan for a large-scale system such as a water supply.

  In order to achieve the above object, the present invention comprises the following arrangement. That is, in an operation plan server connected to a facility through a network, an operation condition storage unit that stores the operation condition of the facility, an input unit that receives input of setting parameters from an operator, and an operation stored in the operation condition storage unit A plan planning unit that formulates an operation plan based on conditions and setting parameters input from the input unit, calculates an index of the planned operation plan, and the operation plan index and the operation plan are referenced for each operation plan. A history storage unit that stores reference number information indicating the cumulative number of times, and a list of operation plan indices stored in the history storage unit and reference number information of each operation plan are displayed on the display screen for the operator. An output unit for outputting the output.

  According to the present invention, it becomes possible for an operator to make an appropriate operation plan more easily.

  First, an outline of an embodiment of the invention will be described.

In this embodiment, a plurality of operation plans prepared in the past are stored as history information, and the number of times of reference of each operation plan referred to when the operator makes an operation plan is stored as history information. Keep it. When an operator creates a new operation plan, an operation plan that has been frequently drafted in the past is presented to the operator as important.
Also, the usefulness of each operation plan evaluated when the operator makes an operation plan is stored together as history information. When the operator creates a new operation plan, an operation plan that has been prepared in the past is presented to the operator as important as an important one.

  Hereinafter, the embodiment applied to the water operation planning system related to the facility operation of the waterworks will be described in detail.

  [1-1: System Configuration] FIG. 1 shows a system configuration diagram of the present embodiment.

  The waterworks facility 100 includes a water intake channel 141 and a water intake channel 142 that take raw water from a river and send it to a water purification plant, a water purification plant 151 and a water purification plant 152 that store raw water until the raw water is purified and water is sent to the water purification plant, and a water supply reservoir from the water purification plant. A water supply channel 161, a water supply channel 162, a water supply channel 163, a water supply channel 164, a water supply channel 165 and a water supply channel 166, a distribution reservoir 171, a distribution reservoir 172, a distribution reservoir 173, It consists of a reservoir 174.

  The river 131 and the water purification plant 151 are connected by the intake channel 141, and the river 132 and the water purification plant 152 are connected by the water intake channel 142. The raw water flowing through the river (code 131, code 132) is the water intake channel (code 141, code 142) to the water purification plant (reference numeral 151, reference numeral 152). In addition, the water purification plant 151 and the water reservoir 171 are connected by the water channel 161, the water purification plant 151 and the water reservoir 172 are transmitted by the water channel 162, and the water purification plant 152 and the water reservoir 171 are transmitted by the water channel 163, and the water purification plant 152 and the water reservoir 173 is connected to the water supply channel 164, the water purification plant 152 and the distribution reservoir 174 are connected to each other by the water transmission channel 165, and the water supply reservoir 172 and the water distribution reservoir 173 are connected to each other through the water supply channel 166. The treated purified water is supplied to the reservoir (reference numeral 171, reference numeral 172, reference numeral 173, reference numeral 174) via the water supply channel (reference numeral 161, reference numeral 162, reference numeral 163, reference numeral 164, reference numeral 165, reference numeral 166). In the distribution reservoir (reference numeral 171, reference numeral 172, reference numeral 173, reference numeral 174), a demand amount that changes with the time of a consumer such as a home or a factory is generated.

  The operation planning system 110 is a server, for example, a human interface unit 111, a facility information interface unit 112, a history management unit 113, a parameter setting unit 114, an operation condition prediction unit 115, a planning unit 116, a display reference management unit 117, a history The storage unit 118, the operation condition storage unit 119, and the display reference storage unit 120 are configured.

  Here, the history management unit 113, the parameter setting unit 114, the operation condition prediction unit 115, and the planning unit 116 are hardware or software for executing history management, parameter setting, operation condition prediction, and planning, respectively. When these are configured as software, the history management unit 113, parameter setting unit 114, operation condition prediction unit 115, and planning unit 116 are called into the memory by a central processing unit (not shown) such as a CPU. Executed. Processing operations, processing contents, and flowcharts of the operation planning system to be described later are all performed on the premise of the above hardware configuration.

  Further, the history storage unit 118, the operation condition storage unit 119, and the display reference storage unit 120 are each stored in a database.

  The facility information interface unit 112 obtains facility information such as facility restrictions at the time of planning, distribution reservoir water level, and waterway flow rate from sensors and devices installed in each facility of the water supply facility 100 through a network. The operation condition prediction unit 115 obtains information such as a weather forecast from the facility information interface unit 112, and performs prediction calculation such as a demand amount of water during the planning period and its fluctuation, and a change in raw water turbidity during the planning period. This prediction, facility restrictions, and facility information are integrated and stored in the operation condition storage unit 119 as operation conditions. Here, the operation condition is a numerical value representing a precondition of calculation or a condition required to be satisfied by the plan in the calculation of the planning. The structure of data stored in the operation condition storage unit 119 is shown in FIG. In FIG. 18, types indicating facilities and the like, and items and contents as operation conditions in the facilities are described as a table. In the present embodiment, the plan refers to the water level of all the water purification plants and distribution reservoirs and the flow rate of all the intake channels and the water supply channels over a certain period of time (planning period) in the water supply facility. The data structure of one plan is shown in FIG. In FIG. 17, a type indicating a facility, an item that is a plan for the facility, a time, and a plan value at the time are described.

  The parameter input by the operator through the human interface unit 111 by the information input unit 122 is digitized by the parameter setting unit 114 and sent to the planning unit 116.

  The plan making unit 116 makes a plan using the operation condition data stored in the operation condition storage unit 119 and the setting parameter sent from the parameter setting unit 114, and calculates a plan index. The planned plan is additionally stored in the history storage unit 118 together with the setting parameters used for the planning and the index calculated from the plan. The specific method of planning will be described later. In the water operation planning system, the index includes, for example, operating cost, CO2 generation amount, sludge generation amount, power consumption amount, and flow fluctuation rate. The parameter is information indicating weighting of operating cost, CO2 generation amount, sludge generation amount, power consumption amount and flow fluctuation rate.

  Information about each plan stored in the history storage unit 118 is processed by the history management unit 113 and output to the information output unit 121 such as a display screen through the human interface unit 111. When the operator requests the history management unit 113 to select / refer to the plan already calculated through the human interface unit 111 by the information input unit 122 based on the information output to the information output unit 121, the history management unit 113. Reads the plan stored in the history storage unit 118 and performs processing. The history management unit 113 corrects the data stored in the history storage unit 118 as necessary.

  When the operator works on the display standard management unit 117 to display whether the plan has achieved one or more of the standards stored in the display standard storage unit 120 through the human interface unit 111 by the information input unit 122 The reference management unit 117 reads data relating to the requested reference from the display reference storage unit 120 and sends the information to the history management unit 113. The history management unit 113 uses the data related to the reference sent from the display reference management unit 117 to output information related to the plan to the information output unit 121 through the human interface unit 111.

  The human interface unit 111, the history management unit 113, the parameter setting unit 114, the operation condition prediction unit 115, the planning unit 116, and the display standard management unit 117 are configured using a general computer including a personal computer, for example. I can do it.

  The information output unit 121 is configured by a display or the like as a unit that displays various dialogs described later. The human interface unit 111 sends, to an information output unit 121 such as a display screen, an index of a plurality of operation plans stored in the history storage unit and reference number information of the operation plan to be described later for an operator who determines the operation plan. It works as an output unit that outputs so that it can be displayed in a list. The information input unit 122 includes a keyboard, a mouse, and the like that are used for setting parameters and selecting a history, which will be described later. The operation plan determined by the operation planning system 110 is transmitted to each facility through the network, and each facility operates according to the determined operation plan.

  [1-2: State Transition] FIG. 2 is a state transition diagram illustrating the operation of the operation planning system according to the embodiment.

  In the initialization process (reference numeral 201), the operating conditions are created and initial parameters for planning are set. Further, the following dialog is displayed on the information output unit 121 through the human interface unit 111. Specifically, the parameter setting dialog shown in FIG. 9, the dialog for displaying the history search structure shown in FIG. 4, the dialog for displaying the history index shown in FIG. 8 as a radar chart, and the history index shown in FIG. Is a scatter diagram matrix display dialog, a water system diagram shown in FIG. 12 is displayed, a dialog for selecting a plan detail display target, a plan detail display dialog shown in FIG. 14, and a display standard shown in FIG. 10 is selected. (Details of each figure will be described later). These dialogs may allow the operator to select display / non-display as required.

  Next, a planning calculation process is performed in the planning calculation (reference numeral 202). Here, a plan is prepared by the planning unit 116, and an index of the obtained plan is calculated. The setting parameter, the plan, and the index are stored in the history storage unit 118. Details will be described later.

  After the planning calculation 202, the display of the plan, index, and history to the operator is updated by history display update (reference numeral 203).

  Here, the index is a numerical value calculated from the operating conditions, the setting parameters, and the plan formulated by them, and indicates an index for determining superiority or inferiority according to the numerical value when evaluating the plan from a certain aspect. In this embodiment, operating cost, CO2 generation amount, sludge generation amount, power consumption amount, and flow rate fluctuation rate are used as indices. The data structure of the index calculated from one plan is shown in FIG. In FIG. 20, the operation cost, CO2 generation amount, sludge generation amount, power consumption amount, and flow rate fluctuation rate are described as an example.

After the display of each dialog is updated by history display update (reference numeral 203), the operation waits (reference numeral 204).
In the operation waiting (reference numeral 204), the operation of the operator is awaited and the state is shifted to one of the following six states according to the operation. The state to be shifted from the operation waiting 204 is a history reproduction operation 208, a usefulness rank operation 209, a parameter change 207, a display reference change 210, a plan detail display 211, and a transmission process 205.

  Hereinafter, an operation involving the transition to each state in the above order and a process after the transition to each state will be described.

  [2: History Reproduction Operation] FIG. 3 is a detailed state transition diagram regarding the history reproduction operation. The history data stored in the history storage unit 118 includes a dialog for displaying a history search structure shown in FIG. 4 to be described later, a dialog for displaying history indexes shown in FIG. 7 in a matrix of a scatter diagram, and FIG. It is displayed from a different point of view in the dialog that displays the historical index in the radar chart.

  As shown in FIG. 3, in the dialog 400 displaying the structure of the history search, the dialog 700 displaying the history index in a scatter diagram matrix, or the dialog 800 displaying the history index in a radar chart, the current selection is performed. When a node different from the node representing the planned plan is selected by the operator, the state shifts from the operation waiting 204 to the history reproduction operation 208.

  In the history reproduction operation 208, the newly selected plan is read from the data stored in the history storage unit 118, and the reference rank (details will be described later) of the corresponding plan is increased by 1, and the data in the history storage unit 118 is updated. Update. 9. Then, in the history display update 203, the dialog 900 for parameter setting shown in FIG. 9, the dialog 1200 for displaying the water system map shown in FIG. 12 and selecting the display target of the plan details, and the details of the plan shown in FIG. Each display of the dialog 1400 to be updated is updated to that of the selected plan, and the operation waits 204 again.

  Hereinafter, details of the three dialogs closely related to the history reproduction operation and the reference rank for recording the history reproduction operation will be described in order.

  [2-1: Dialog Displaying History Search Structure] FIGS. 4 and 5 are diagrams showing a display example of a dialog displaying the history search structure in this embodiment. In this figure, reference numeral 400 is a dialog for displaying a history search structure, reference numeral 401 is a button for opening a usefulness rank setting menu to be described later, reference numeral 410 is a region in which a changed structure is displayed in a tree, reference numerals 411 to 415, etc. It is a node that represents one plan.

  One or more plans can be selected at the same time. The effect of selecting a plurality of plans will be described later together with a function for displaying the details of the plan.

  For example, when one plan is selected, a dialog 400 that displays a history search structure as shown in FIG. 4 distinguishes the currently selected plan by painting it out like a node 412. For example, when two plans are selected, they are displayed as shown in FIG. 5, and the currently selected plan is painted and expressed as a node 412 and a node 415 to be distinguished.

  This selection state is shared between the dialog 400 that displays the structure of the history search, the dialog 700 that displays the history index described below in a scatter diagram matrix, and the dialog 800 that displays the history index as a radar chart. The

In the area 410 where the change structure is displayed in a tree view, when two nodes are connected by a solid line, a node located on the upper side is a parent node, and a node located on the lower side is a child node. The relationship between the parent node and the child node is that the child node is derived from a parameter set by the operator correcting the parameter of the parent node. In other words, when the operator selects a parent node and sets a new parameter by correcting the parameter of the parent node, the plan generated by the set parameter is displayed as a child node.
For example, the node 411 and the node 412, the node 411 and the node 413, and the node 413 and the node 414 in FIG. Both the node 412 and the node 413 are plans generated by the operator modifying the parameters of the node 411. The operation for changing the parameter by the operator will be described later.

  Here, the information regarding the parent node and the child note is stored in the history storage unit 118 as shown in FIG. In FIG. 22, each row of the table corresponds to one plan and stores information associated with the plan. Each plan has a unique serial number that does not overlap with other plans. In addition to the serial number, it has a column for storing the serial number of the parent node, the parameters used when planning, the plan data itself, the index calculated from the plan, the reference rank, and the usefulness rank.

  The child node records the serial number of the parent node in the parent node serial number column of the corresponding row. For example, the rows of serial numbers 5, 6, and 7 correspond to the nodes 411, 412, and 413 in FIG. Since both the node 412 and the node 413 have the node 411 as the parent node, the values of the parent node serial number columns in the rows of the serial numbers 6 and 7 corresponding to the node 412 and the node 413 are both serial numbers corresponding to the node 411. 5.

  In the columns of setting parameter, plan data, and index, parameters having the data structure shown in FIG. 19, plan data having the data structure shown in FIG. 17, and indices having the data structure shown in FIG. 20 are recorded. Yes.

  [2-2: Dialog Displaying History Indexes in a Scatter Plot Matrix] FIG. 7 is a diagram showing a display example of a dialog for displaying indexes of histories in a scatter diagram matrix in this embodiment. In this figure, reference numeral 700 is a dialog for displaying a history index in a scatter diagram matrix, reference numeral 701 is a button for opening a usefulness rank setting menu described later, reference numeral 720 is a display area of a scatter diagram matrix, reference numerals 721 and 722 are It is an element of a scatter diagram matrix.

  As the meanings of the rows and columns of the scatter diagram matrix, the rows represent the operating cost, the CO2 generation amount, the sludge generation amount, the power consumption amount, and the flow rate fluctuation rate in order from the top to the bottom and the columns from the left to the right. Correspondingly, in the scatter diagram of the element 721 of the scatter diagram matrix, the vertical axis represents the flow rate fluctuation rate and the horizontal axis represents the sludge generation amount, and in the scatter diagram of the element 722 of the scatter diagram matrix, the vertical axis represents the operation cost. The axis represents power consumption.

  In the display area 710 of the scatter diagram matrix and the scatter diagram selected / enlarged, each plan stored in the history storage unit 118 is plotted using the index value.

  Reference numeral 710 denotes a display area of the selected / enlarged scatter diagram, and the element 721 currently selected among the elements of the scatter diagram matrix is enlarged and displayed. Reference numerals 711 to 715 displayed in the display area 710 of the selected / enlarged scatter diagram are nodes corresponding to the above-described plan, and are the same as the nodes 411 to 415 of the dialog 400 displaying the structure of the history search. Represents a plan.

  The display area 710 of the selected / expanded scatter diagram can display an arbitrary element of the scatter diagram matrix in an enlarged manner. For example, when the operator selects the element 722 of the scatter diagram matrix with the mouse while the element 721 is selected, the display content of the display area 710 of the scatter diagram selected / enlarged is currently The content of the element 721 is changed to the content of the newly selected element 722.

  [2-3: Dialog for Displaying Index of History as Radar Chart] FIG. 8 is a diagram showing a display example of a dialog for displaying an index of the history as a radar chart in this embodiment. In this figure, reference numeral 800 is a dialog for displaying a history index in a radar chart, reference numeral 801 is a button for opening a usefulness rank setting menu described later, reference numerals 812 and 813 are polygons each representing one plan.

  Polygons 812 and 813 represent the same plans as the nodes 412 and 415 in the dialog 400 for displaying the history search structure, respectively. In addition, the polygon 812 represents a currently selected plan, and is displayed with a bold line so as to be distinguished from other polygons.

[2-4: Reference rank]
The dialog 400 displaying the history search structure in FIG. 4, the dialog 700 displaying the history index in a scatter diagram matrix in FIG. 7, and the dialog 800 displaying the history index in a radar chart in FIG. The size and shape of the node represent the reference rank and usefulness rank of the plan, respectively.

  In the area 410 in which the changed structure is displayed in the tree, the display area 710 of the scatter chart selected and enlarged, and the display area 810 of the chart, in this embodiment, the larger each node is, the higher the reference rank of the plan of that node is. . The reference rank is an index added to the plan, and represents how often the plan is referenced after the plan is generated. As the reference rank, the number of reference times of the plan, particularly the total number of reference times can be used. The reference count is recorded in the history storage unit for each operation plan as shown in FIG.

  A plan with a large number of references is a plan that the operator is paying attention to. There is a high possibility that a plan that the operator has paid attention to and has been referred to many times in the past is a plan whose index value is in an appropriate range or a plan around it. By managing this reference count in the planning process by the computer system and presenting it to the operator, the operator does not have to be careful not to forget the focused plan, and can concentrate on searching for a more desirable plan. In particular, in a water operation planning system with a large number of plans, it is easy to select a plan with a large number of references as an appropriate plan, and the convenience for the operator is remarkably increased. For example, as shown in FIGS. 7 and 8, a plurality of operation plan indicators stored in the history storage unit, a plurality of operation plan indicators stored in the history storage unit, and reference frequency information of each operation plan are displayed. If it is output so that it can be displayed in a list, it is possible to construct a system that is convenient for the operator.

  A specific system of the operation planning system for realizing the above will be described with reference to FIGS. That is, based on the operation condition storage unit that stores the operation condition of the facility, the input unit that receives the input of the setting parameter from the operator, the operation condition stored in the operation condition storage unit, and the setting parameter input from the input unit A history storage that stores an operation plan, calculates a plan of the planned operation plan, and stores reference count information indicating the operation plan index and the cumulative number of times the operation plan is referenced for each operation plan. And an output unit that outputs to the operator a plurality of operation plan indexes stored in the history storage unit and reference count information of each operation plan so that the list can be displayed on a display screen.

  The following is an example of the reproduction operation. Assume that when the plan of the node 412 is selected as shown in FIGS. 4, 7, and 8, the selection is changed to the node 413 in FIG. 4. Then, in the history reproduction operation 208, in the data stored in the history storage unit 118 shown in FIG. 22, the value of the reference rank column in the row of the serial number 7 corresponding to the node 413 is rewritten from 5 to 6. .

  This completes the description of the history reproduction operation.

  [3: Usefulness Rank Operation] In the usefulness rank operation 209, the usefulness rank, which will be described later, of the plan currently selected from the data stored in the history storage unit 118 is selected from the menu. Change to Then, the display is updated by the history display update 203, and the process shifts to the operation waiting 204 again.

  This implementation is performed in the area 410 where the change structure of the dialog 400 for displaying the history search structure is displayed as a tree and the dialog 700 for displaying the history index as a scatter chart matrix in the selected / enlarged scatter chart display area 710. In the example, the shape of each node represents the usefulness rank of that node's plan. In this embodiment, the usefulness rank is set to three levels of “useful”, “normal”, and “exclusion”, and the usefulness rank is “useful” in a circle like the node 411 and “normal” in a rectangle like the node 412. “×” like the node 415 indicates “exclusion”.

  The usefulness rank is determined by the operator setting to record the usefulness of the plan felt by the operator as will be described later. By displaying the usefulness rank, the operator can know the usefulness that the operator has judged for each plan without looking at the details of the plan in the history display.

  By recording and presenting the usefulness of the operator in the usefulness rank, the operator can easily recognize the judgment of the operator's own usefulness for each plan, so that the desired plan is not buried or undesirable. You can concentrate on searching and narrowing down without paying attention to the plan. In addition to the degree of attention automatically recorded by the above-mentioned reference rank, the usefulness rank records the degree of attention actively given by the operator to assist the operator in evaluating each plan.

  The button 401 is pressed by the operator in the dialog 400 for displaying the history search structure, the button 701 is displayed in the dialog 700 for displaying the history index in a scatter diagram matrix, and the button 801 in the dialog 800 for displaying the history index in a radar chart. If so, a usefulness rank setting menu is opened from the button. When a menu item indicating the usefulness rank set from this menu is selected, the state shifts to the usefulness rank operation 209.

  For example, as shown in FIG. 6A, the node 412 having the “normal” usefulness rank is selected in the dialog 400 that displays the structure of the history search, and the operator presses the button 401 to open the menu 601. When the operator selects “useful” from the menu, the state shifts to an operation 209 having a usefulness rank. In the usefulness rank operation 209, the usefulness rank of the plan corresponding to the node 412 is changed from “normal” to “useful”. That is, in the data stored in the history storage unit 118 illustrated in FIG. 22, the value of the usefulness rank column in the row of the serial number 6 corresponding to the node 412 is rewritten from “normal” to “useful”.

  [4: Parameter Change] FIG. 9 is a diagram showing a display example of a parameter setting dialog in this embodiment. In this figure, reference numeral 900 is a parameter setting dialog, reference numeral 901 is a slider for setting a flow rate fluctuation rate weight, reference numeral 902 is a slider for setting a power consumption weight, and reference numeral 903 is a sludge generation weight. It is a slider. The numerical value of the corresponding parameter is set according to the position of each slider.

In the parameter setting dialog 900, when any of sliders 901 to 903, which will be described later, is moved by the operator's input operation, the state shifts from the operation waiting 204 to the parameter change 207.
In the parameter change 207, the parameter setting unit 114 acquires the positions of the sliders 901 to 903 of the parameter setting dialog 900, converts the slider position information into the numerical values of the parameters whose data structure is shown in FIG. Send to part 116. Then, the process proceeds to the planning calculation 202 to perform the planning / index calculation processing using the set parameters.

  Thereafter, the display of each dialog is updated by the history display update 203. In the area 410 where the change structure of the dialog 400 for displaying the search structure of the history is displayed as a tree, a plan newly calculated by the changed setting parameter is set with a node representing the plan before the setting parameter is changed as a parent node. A new child node that represents is added and selected as a plan. A node 700 and a polygon representing a new plan are additionally displayed in a dialog 700 for displaying a history index in a scatter diagram matrix and a dialog 800 for displaying a history index in a radar chart.

  After the display is updated, the process again shifts to operation waiting 204.

[5: Change display standard]
FIG. 10 is a diagram showing a display example of a dialog for selecting a display criterion for the function of displaying the achievement of the plan criterion in the present embodiment. In this figure, reference numeral 1000 is a dialog for selecting a display reference, reference numeral 1001 is a check box for selecting whether or not to display a reference regarding flow rate fluctuations, reference numeral 1002 is a check box for selecting whether or not to display a reference regarding power consumption reduction, and reference numeral 1003 Is a check box for selecting whether or not to display a standard for sludge generation reduction.

In the dialog 1000 for selecting a display reference, when the selection state of the check boxes 1001 to 1003 is changed, the state shifts from the operation waiting 204 to the display reference change 210.
In the display reference change 210, for the reference selected in the check box 1001 to the check box 1003 of the dialog 1000 for selecting the display reference, an index to which each reference is focused and the data of the achievement threshold are displayed from the display reference storage unit 120. read out. Then, the display is updated by the history display update 203, and the process shifts to the operation waiting 204 again.

  Here, the reference is for the computer to evaluate the plan, and it can be determined whether or not the plan is achieved from the index value calculated from the plan. For example, when the value of the index of the power consumption of the entire enterprise relating to transmission and distribution water estimated from the plan is equal to or less than a predetermined constant, the criterion for power consumption reduction is achieved.

  The standard achievement determination procedure may be a procedure determined regardless of the operation condition, or may be a procedure that changes according to information collected by the operation planning system such as the operation condition or input by the operator. For example, the standard for power consumption reduction determines the procedure so that the threshold for judging whether or not to achieve is changed depending on the predicted total demand amount in the planning period.

  FIG. 21 is a diagram illustrating a data configuration stored in the display reference storage unit 120 of the present embodiment.

  As will be described later in the description of the display reference change 210, the change structure of the dialog 400 for displaying the structure of the history search as shown in FIG. 11 for the reference selected in the check boxes 1001 to 1003 is displayed as a tree. 410 and each of the nodes displayed in the display area 710 of the enlarged scatter diagram in the dialog 700 for displaying the history index in a scatter diagram matrix are displayed by distinguishing them depending on whether or not the criteria are achieved.

  In FIG. 11, each node indicating the plan displayed in the area 410 where the changed structure is displayed in a tree and the display area 710 of the selected / enlarged scatter diagram is a reference regarding the flow rate fluctuation displayed by selecting the check box 1001. Is displayed with the symbol i in the upper right corner of the node. Similarly, the symbol iii is displayed at the upper right of the node only when and only when the criterion regarding the sludge generation amount reduction displayed by selecting the check box 1003 is achieved.

  For example, the node 711 does not achieve the standard regarding the flow rate fluctuation, but has achieved the standard regarding the sludge generation amount reduction, so the symbol iii is displayed at the upper right of the node. Since the node 712 has not achieved both the standard regarding the flow rate fluctuation and the standard regarding the sludge generation amount reduction, nothing is displayed at the upper right of the node. Since the node 714 has achieved the standard regarding the flow rate fluctuation but has not achieved the standard for the sludge generation amount reduction, only the symbol i is displayed at the upper right of the node.

  In FIG. 11, whether or not the standard is achieved is distinguished by displaying a symbol such as “i” or “iii” at the upper right of the node. However, as a method for distinguishing whether or not the standard is achieved, there are other methods such as coloring. Can be used.

  Further, for example, as shown in FIG. 11 (b), it is related to the achievement determination of the standard in which the index selected as the vertical axis and the horizontal axis of the scatter diagram displayed in the display area 710 of the scatter diagram selected and enlarged is displayed. In this case, the threshold for achieving the standard may be displayed as a straight line 1102 and a straight line 1103. A straight line 1102 parallel to the horizontal axis represents the achievement threshold of the standard related to the flow fluctuation, and a node below the straight line 1102 achieves the standard related to the flow fluctuation. Similarly, a straight line 1103 parallel to the vertical axis represents an achievement threshold value of the standard for sludge generation amount reduction, and a node on the left side of the straight line 1103 achieves a standard for sludge generation amount reduction.

  For the evaluation that can make a judgment from the value of the index for the plan, the operator can leave the evaluation for each plan partially to the computer by calculating whether the standard is achieved and displaying it together with the history. This simplifies the process of narrowing down and makes it possible to focus on decision making.

  In addition, it is known that a person can easily make a decision when a criterion for determination is clearly indicated. In this embodiment, it is expected that the selection of a plan is facilitated by displaying the criterion.

  [6: Selection Change of Detailed Display of Plan] FIGS. 12 and 13 are diagrams showing a display example of a dialog for displaying a water system diagram of this embodiment and further selecting a facility as a display target of the details of the plan.

  In this figure, reference numeral 1200 is a dialog for displaying a water system map and selecting a plan detail display target, reference numeral 1231 is a display of a river 131, reference numeral 1232 is a display of a river 132, reference numeral 1241 is a display of an intake channel 141, reference numeral 1242 Is the display of the intake channel 142, 1251 is the display of the water purification plant 151, 125 is the display of the water purification plant 152, 1261 is the display of the water supply channel 161, 1206 is the display of the water supply channel 162, and 1263 is the display of the water supply channel 163.

  For example, in FIG. 12, the reference numeral 1271 is surrounded by a frame 1201, indicating that the reservoir 171 has been selected. Similarly, in FIG. 13, the display of reference numeral 1242 is surrounded by a frame 1201, indicating that the intake channel 142 is selected.

  Of the selected plan, the details of the selected facility are displayed in a graph in a dialog 1400 that displays the details of the plan shown in FIG.

  FIG. 14 is a diagram showing a display example of a dialog for displaying the details of the plan in a graph in this embodiment. In this figure, reference numeral 1400 is a dialog for displaying the details of the plan, and reference numeral 1401 is a combo box for selecting a facility to display a graph.

  For example, in FIG. 14, the details regarding the water level of the distribution reservoir 171 in one selected plan are displayed in a graph. A facility whose details are displayed in a graph is selected by a combo box 1401 or by selecting a facility display in a dialog 1200 for displaying a water system diagram and selecting a plan detail display target. This selection state is shared by a combo box 1401 and a dialog 1200 for displaying a water system diagram and selecting a plan detail display target.

In the dialog 1200 for displaying the water system map and selecting the display target of the plan details, the display of one facility different from the display of the facility currently selected as the display target of the plan details is selected from reference numerals 1241 to 1274. In this case, the status shifts from the operation waiting 204 to the detailed plan display 211. Alternatively, even when one facility different from the facility currently selected in the combo box 1401 of the dialog 1400 for displaying the plan details is newly selected, the state shifts from the operation waiting 204 to the plan detail display 211.
In the detailed plan display 211, the graph display is updated to the detailed plan of the facility corresponding to the facility display selected in the dialog 1400 for displaying the detailed plan shown in FIG. In addition, the selection is made so that the selection of the combo box 1401 and the selection in the dialog 1200 for selecting the display target of the plan details by displaying the water system map become the same newly selected facility. Thereafter, the process again shifts to operation waiting 204.

  When a plurality of plans are selected in the dialog 400 for displaying the history search structure, the dialog 700 for displaying the history index in a scatter chart matrix, and the dialog 800 for displaying the history index in a radar chart, In the dialog 1200 for displaying the genealogy and selecting the display target of the plan details, the display reflecting the differences between the selected plans is performed as shown in FIG.

In the present embodiment, for a plurality of plans, intake channels / water channels whose difference in flow rate plan values at the same time are 30% or more with respect to the upper and lower flow widths of the intake channels / water channels are highlighted. In addition, for a plurality of plans, the intake channel / water channel whose difference in the flow rate plan value at the same time is 50% or more with respect to the upper and lower flow widths of the intake channel / water channel are further highlighted. In other words, the intake channel / water channel whose values of the following formula (1) exceed 0.3 and 0.5 are distinguished and highlighted.

  For example, in the dialog 1200 for displaying the water system map of FIG. 13 and selecting the display target of the details of the plan, the value of the expression (1) of the intake channel 142 is 0.3 or more and less than 0.5 for the plurality of selected plans. Yes, the value of the expression (1) of the water channel 163 is 0.5 or more, and the value of the expression (1) of other intake channels / water channels is less than 0.3. A pop-up 1301 and a pop-up 1302 are displayed and highlighted on the waterway display 1163, respectively.

  The display reflecting the difference between a plurality of selected plans is not limited to the pop-up method described here.

  FIG. 15 is a diagram showing a display example of a dialog for displaying the details of a plan in a graph in the present embodiment when a plurality of plans are selected. For example, in FIG. 15, two plans are selected as illustrated in FIG. 5, and the details regarding the flow rate of the intake channel 142 among these plans are displayed in a graph. The details of the two plans are shown as a graph with a solid line and a broken line, respectively. Further, a legend 1501 is displayed to distinguish the two plans.

  By displaying the plan values of one facility over a plurality of plans, the operator can easily recognize which part is different.

  In the plan that has the function described here that the operator can make a detailed comparison in the plan that is narrowed down with the help of the history display function, reference rank and usefulness rank function, and standard display function. Detailed display facilitates and speeds up satisfactory plan decisions.

  [7: Decision operation] When the operator is satisfied with the currently selected plan and decides to adopt the plan and informs the system, the status moves from the operation waiting 204 to the transmission processing 205, and then the termination processing 206 is executed. Do. In the transmission process, after confirmation, the planned value is transmitted to each water supply facility through the facility information interface unit 112. In the termination process, the memory is released and the execution of the system is terminated.

  [8: Planning / Index Calculation] In the planning calculation 202, the planning process and the index calculation process are performed according to the flow shown in FIG.

  Step 1601 is a process for acquiring operating conditions and parameters. The operation conditions necessary for the planning are stored in the operation condition storage unit 119 having the data structure of FIG. 18 and the setting parameters of the data structure of FIG. 19 set by the slider or the like in the parameter setting dialog 900 are acquired. To do.

Step 1602 is a process for executing the calculation calculation of the operation plan. Specifically, it is formulated as a multipurpose planning problem and a plan is created as the optimal solution. The purpose is the expression (2) that expresses the flow rate fluctuation of the water channel that wants to suppress the fluctuation that is the stability of the facility operation, the expression (3) that expresses the power consumption to measure the energy saving, and the by-product associated with the operation of the water supply facility Three objective functions of Expression (4) expressing the amount of sludge generated, which is the amount generated, are set.

  Restrictions of the planning problem include the connection between the intake channel and the water treatment plant, the water treatment plant and the water channel, the distribution reservoir and the water channel, the demand in the distribution reservoir, the upper and lower limits of the flow rate of the intake channel and the water channel, the distribution reservoir Set the water level upper and lower limits.

Under these constraint conditions, the data in FIG. 17 is obtained by performing the optimization calculation using the formula (5) obtained by multiplying the formula (2), the formula (3), and the formula (4) by adding the weighting coefficient as an evaluation formula. Create a "plan" with a structure.

  As the weight coefficients w1, w2, and w3 of each objective function, the parameters set in the parameter setting dialog 900 whose structure is shown in FIG. 19 are used.

Step 1603 is a process for calculating an index from the planned value of the calculation result. In this embodiment, as shown in FIG. 20, the operating cost, CO2 generation amount, sludge generation amount, power consumption amount, and flow rate fluctuation rate are calculated as indices.
Equation (4) can be used for calculating the sludge generation amount, Equation (3) can be used for calculating the power consumption, and Equation (2) can be used for calculating the flow rate fluctuation rate.

  For other indicators, calculation is performed using a plan by setting an appropriate calculation formula.

  As long as it is a numerical value calculated from the operating conditions, the setting parameters, and the plan made based on them, it is possible to use indices other than those exemplified here. The operator may be able to edit the calculation formula of the index, or the index to be displayed may be selected from a plurality of prepared indexes.

  Step 1604 is a process of creating a new child node whose parent is the node before the change in the history storage unit 118 and storing the result.

  Select the newly added node as the current plan.
