[First Embodiment]
In one embodiment, the planning unit 730, based on the demand cost information of each factory, (i) the total of the utilities supplied to each factory is equal to or less than the target value indicated by the information acquired by the reduction request acquisition unit 714. And (ii) the total of the indexes indicating the production cost of goods in one or more factories is supplied to each factory so as to satisfy a predetermined condition (sometimes referred to as a first condition). Create a utility supply plan.

The first conditions are (a) the condition that the total of the indexes indicating the production costs of goods in one or more factories does not correspond to the maximum value of the total of the production costs, and (b) the total of the above indexes is the production. Examples include a condition that the total cost is smaller than a predetermined value, and (c) a condition that the total of the indicators corresponds to the minimum value of the total of the production costs. For example, when the index indicating the production cost of an article is the cost related to one or more specific utilities, the first condition is that (a) the total cost related to one or more utilities described above is not the maximum. The conditions, (b) the condition that the total of the above costs is smaller than a predetermined value, or (c) the condition that the total of the above costs is the minimum can be exemplified.

Under the condition (a) above, the judgment as to whether or not the total of the indexes indicating the production costs of goods in one or more factories corresponds to the maximum value of the total of the production costs is calculated by calculating the total of the indexes. It may be done at times or after the fact. An index showing the production cost of goods at each factory can be determined based on the amount of utility supplied to the factory. Therefore, the total of the indicators indicating the production cost of the goods can be determined based on the combination of the utility supply amount to each factory. The above condition (a) is satisfied, for example, by calculating the total of the indexes indicating the production cost of the article by the following procedure.

According to one embodiment, first, the combination of utility supply amounts to each factory is variously changed to calculate the total of indicators indicating the production cost of goods. Then, after calculating the calculation result of the nth time (n is an integer of 2 or more), the calculation result of the nth time and the calculation result of the n-1th time are compared. If the nth calculation result is smaller than the n-1th calculation result, the n + 1th trial is started. On the other hand, if the nth calculation result is larger than the n-1th calculation result, the n-1th calculation result is adopted as the total of the indexes indicating the production cost of the article.

According to another embodiment, a combination of utility supplies to each factory is determined based on an arbitrary algorithm or an arbitrary standard, and the calculation result in the combination is adopted as a total of indicators indicating the production cost of the goods. To do. Even in such a case, the total of the indicators indicating the production cost of the goods in other combinations of the utility supply amount to each factory is calculated ex post facto, and the calculation result is the value currently adopted. If it is larger than, it can be determined that the above condition (a) is satisfied.

For example, a "sum of indicators of the cost of producing goods in one or more factories" indicates the cost of producing goods in one or more factories in other combinations of utility supplies to each of one or more factories. If it is smaller than the "total of indicators", the condition (a) is satisfied. More specifically, the planning department 730 has made a supply plan stating that "the upper limit of the amount of electric energy supplied to each of factory A, factory B and factory C is 10 kWh / day, 5 kWh / day and 15 kWh / day". In the case of creation, it is assumed that the total production cost of factory A, factory B and factory C is 10 million yen. Here, in the combination that "the upper limit of the amount of electric energy supplied to each of the factory A, the factory B, and the factory C is 10 kWh / day, 10 kWh / day, and 10 kWh / day", the factory A, the factory B, and the factory C When the total production cost of the above is calculated, if the total exceeds 10 million yen, the supply plan created by the planning unit 730 satisfies the condition (a) above.

In the present specification, the term "minimum" means not only the minimum value calculated analytically or the minimum value calculated by numerical analysis, but also "a value 10% smaller than the minimum value and 10 from the minimum value". Includes "values less than or equal to% larger". Further, for example, when the minimum value of the total of the indicators indicating the production cost cannot be calculated analytically, the planning unit 730 has a probability that the total of the indicators indicating the production cost corresponding to a specific supply plan is the minimum. If it is larger than a predetermined value, it may be determined that the total of the indicators indicating the production cost is the minimum. When the planning unit 730 repeats the process of calculating the total a predetermined number of times, the supply plan corresponding to the minimum value in the plurality of trials is a condition that the total of the indexes indicating the production cost is minimized. You may judge that you are satisfied.

To create.

The third condition is (a) the condition that the total of the indexes indicating the amount of by-products discharged from one or more factories does not correspond to the maximum value of the total of the total amount of the discharge, and (b) the above-mentioned index. Illustrate the condition that the total indicates that the total of the emissions is smaller than the predetermined value, and (c) the condition that the total of the above indicators corresponds to the minimum value of the total of the emissions.

In still another embodiment, the planning unit 730 obtains a reduction request based on the emission cost information of each factory, (i) the total of the indexes indicating the emission amount of by-products emitted from one or more factories. One or more factories so that the total of the indexes indicating the production cost of goods in (ii) one or more factories satisfies the predetermined first condition so as to be less than or equal to the target value indicated by the information acquired by the part 714. Create a supply plan for the utilities supplied to each of them.

In the present embodiment, the operation information acquisition unit 732 acquires the operation information of each device of the production process device 142 and the utility process device 144 from the control device 130. The driving information acquisition unit 732 may transmit the driving information to the incentive management unit 734.

In the present embodiment, the incentive management unit 734 provides an incentive according to the supply amount of the utility. The incentive management unit 734 provides, for example, an incentive according to the reduction amount or reduction rate of the utility. The incentive management department 734, for example, if the supply amount of the utility to the factory that agrees with the utility supply plan decided by the planning department 730 among one or more factories satisfies the supply plan, the factory that agrees with the supply plan On the other hand, incentives are given according to the supply amount of utilities.

In the present embodiment, the report creation unit 736 creates a report on the supply and demand of utilities in each factory. The report creation unit 736 may create a report including information on driving information and incentives.

FIG. 8 schematically shows an example of information processing in the supply and demand management system 100. According to the present embodiment, first, in step 802 (step may be abbreviated as S), the supply and demand management system 100 executes a supply plan drafting process. Specifically, the management server 110 determines the upper limit of the amount of utilities supplied to each factory. Next, in S804, the supply and demand management system 100 executes the process monitoring process. Specifically, the control device 130 of each factory monitors the operating status of the production process equipment 142 and the utility process equipment 144. After that, in S806, the supply and demand management system 100 executes the report creation process. Specifically, the management server 110 creates a report on the usage status of the utility during a predetermined evaluation period.

FIG. 9 schematically shows an example of information processing in the supply and demand management system 100. FIG. 9 shows an example of information processing in S802 described in relation to FIG. In FIG. 9, for the purpose of simplifying the explanation, information processing in S802 will be described as an example in which the upper limit of the amount of utility supplied to the factory A is determined by using the demand-cost curve. Those skilled in the art who have come into contact with the description of the present specification can understand that the upper limit value of the utility amount to be supplied to the factory A can be determined by using the demand-emission amount curve or the emission amount-cost curve.

According to the present embodiment, first, in S902, the manager in charge of managing the factory A inputs the production plan of the factory A to the manager terminal 216. For example, the manager inputs the production plan for the day at a predetermined time. The input unit 226 of the control device 130 acquires the information input by the administrator and transmits it to the control unit 230.

Next, in S904, the correlation determination unit 416 of the control unit 230 determines the demand-cost curve and creates the demand cost information. For example, the correlation determination unit 416 first analyzes the production plan input by the manager, and identifies the type and amount of work in the target period of the production plan. Next, the correlation determination unit 416 determines an index indicating the production cost. Then, a mathematical analysis simulation is executed to determine the type of utility required to process the work in the target period of the production plan and the amount of each utility so that the index indicating the production cost is minimized. As a result, the reference value of the utility demand amount and the reference value of the index indicating the production cost can be calculated.

Next, the correlation determination unit 416 adds an upper limit of the supply amount of a specific single utility to the constraint condition of the mathematical analysis simulation. Then, the upper limit of the supply amount of the utility is changed to various values, and the mathematical analysis simulation is executed so that the index indicating the production cost is minimized. As a result, a plurality of data in which the upper limit value of the supply amount of the utility and the minimum value of the index indicating the production cost are paired are generated. By performing data fitting using an arbitrary function on the above-mentioned plurality of data, a function showing a demand-cost curve can be obtained. The correlation determination unit 416 transmits a function showing a demand-cost curve to the management server 110.

The correlation determination unit 416 uses a plurality of data obtained by the mathematical analysis simulation to indicate the fluctuation rate or fluctuation amount of the utility demand amount and the production cost when the reference value of the utility demand amount is used as a reference. A plurality of data may be created in which the fluctuation rate or the fluctuation amount of the index indicating the production cost is associated with the reference value of. The correlation determination unit 416 performs data fitting on a plurality of newly created data by using an arbitrary function to determine the utility demand when the reference value of the utility demand is used as a reference. A function that uses the fluctuation rate or fluctuation amount of the index indicating the production cost as the dependent variable when the fluctuation rate or fluctuation amount is used as the independent variable and the reference value of the index indicating the production cost as the reference value is a function that shows the demand-cost curve. It may be derived as.

On the other hand, in S912, the supply and demand adjustment server 120 transmits information indicating the supply condition of the utility to the management server 110. The reduction request acquisition unit 714 of the management server 110 receives the utility supply conditions. The reduction request acquisition unit 714 confirms the existence and update time of the demand cost information for each of the one or more factories managed by the management server 110. If there is no demand cost information, or if the elapsed time from the update time of the demand cost information to the present is longer than a predetermined period, the reduction request acquisition unit 714 sends the control device 130 that manages the corresponding factory. On the other hand, demand cost information is requested.

The utility supply conditions may be conditions relating to utility supply restrictions. For example, utility supply conditions include information about the upper limit of utility supply over a particular unit time. The unit time may be 30 minutes, 1 hour, 3 hours, 6 hours, 12 hours, or 1 day. Well, it may be one week or one month. The utility supply conditions may include information about incentives for complying with supply limits.

Next, in S922, the planning unit 730 determines a supply plan for each of the one or more factories managed by the management server 110. For example, the planning unit 730 determines a tentative value of the demand amount of each factory so that the total of the utilities supplied to each factory satisfies the supply condition presented by the supply and demand adjustment server 120. Next, the planning unit 730 calculates the value of the index indicating the production cost corresponding to the above-mentioned tentative value by using the demand-cost curve of each factory. The planning unit 730 sums all the calculated values of the indicators indicating the production costs of each factory. The planning unit 730 determines whether or not the calculated total value satisfies the first condition. If the calculated total value does not satisfy the first condition, the above process is repeated. On the other hand, when the calculated total value satisfies the first condition, the supply plan is determined.

Next, in S924, the planning unit 730 transmits the determined supply plan to the control device 130 that manages each factory. In S926, the supply plan acquisition unit 422 receives the information indicating the supply plan and transfers it to the operation plan determination unit 424. The operation plan determination unit 424 determines whether or not to comply with the supply plan. The operation plan determination unit 424 transmits information indicating whether or not to comply with the supply plan to the management server 110.

Next, in S928, the planning unit 730 receives information indicating whether or not to comply with the supply plan from the control device 130 that manages each factory. The planning unit 730 calculates the total demand in each factory based on the response from each factory. In S930, the planning unit 730 determines whether or not the total demand in each factory satisfies the supply condition of the utility presented by the supply and demand adjustment server 120.

If the total amount of demand in each factory does not satisfy the supply condition of the utility presented by the supply and demand adjustment server 120 (No in S930), the process returns to S922 and the supply plan is determined again. On the other hand, when the total amount of demand in each factory satisfies the supply condition of the utility presented by the supply and demand adjustment server 120 (in the case of Yes in S930), the process ends.

After that, in S942, the operation plan determination unit 424 determines the operation plan of the production process equipment 142 and the utility process equipment 144 based on the supply plan determined by the management server 110. Further, the operation plan determination unit 424 automatically changes some settings of the production process equipment 142 and the utility process equipment 144 by remote control. When the setting cannot be changed by remote control, the operation plan determination unit 424 transmits the operation plan or the device setting to the worker terminal 214 or the administrator terminal 216, and prompts the operator or the administrator to change the setting. You may. In S944, the production process equipment 142 and the utility process equipment 144 start operation and end the process.

FIG. 10 schematically shows an example of information processing in the supply and demand management system 100. FIG. 10 shows an example of information processing when an abnormality is detected in the process monitoring process in S804 described in relation to FIG. In FIG. 10, for the purpose of simplifying the explanation, an abnormality is detected in S804 as an example of determining the upper limit of the amount of utility supplied to the factory A by using the demand-cost curve. Information processing in is described.

According to the present embodiment, first, in S1012, each of the production process device 142 and the utility process device 144 transmits the operation information of each device to the control device 130. The monitoring information acquisition unit 432 of the control device 130 receives the operation information from each device and transfers it to the abnormality detection unit 434. Next, in S1014, the abnormality detection unit 434 monitors the operation information from each device. If no abnormality is detected (No in S1014), the abnormality detection unit 434 continues to monitor the operation information.

On the other hand, when an abnormality is detected in S1014 (this is the case of Yes in S1014), in S1022, the abnormality detection unit 434 transmits information indicating that the abnormality has been detected to the process control unit 440. The process control unit 440 transmits information indicating that an abnormality has been detected to the worker terminal 214 or the administrator terminal 216. Further, the abnormality detection unit 434 transmits information indicating that the abnormality has been detected to the correlation determination unit 416, and requests the recalculation of the demand-cost curve.

In S1024, the worker terminal 214 or the administrator terminal 216, which has received the information indicating that the abnormality has been detected, outputs a warning to the worker or the administrator. Then, in S1026, the operator or the administrator adjusts the settings of the device in which the abnormality is detected. At this time, the worker or the manager may access the control device 130 via the worker terminal 214 or the manager terminal 216 and adjust the setting by remote control. Further, the process control unit 440 may automatically adjust the setting.

Further, in S1032, the correlation determination unit 416 of the control device 130 recalculates the demand-cost curve. In S1034, the correlation determination unit 416 compares the demand-cost curve derived by recalculation with the conventional demand-cost curve.

When the difference between the two does not exceed a predetermined value (No in S1034), the correlation determination unit 416 ends the process. Further, the control device 130 returns to S1014 and continues the process.

On the other hand, when the difference between the two exceeds a predetermined value (Yes in S1034), the correlation determination unit 416 determines to notify the management server 110 of the change in the demand-cost curve, and the notification determination unit 436 is requested to notify the management server 110 of the change in the demand-cost curve. The notification determination unit 436 transmits information indicating that the demand-cost curve has changed to the management server 110.

Then, in S1042, the management server 110 and the control device 130 execute the processes S922 to S930 described in relation to FIG. 9 to recalculate the utility supply plan for each factory. In S1044, the control device 130 changes the settings of each device in the same manner as in S942 described with reference to FIG. Further, the operation of each device is restarted in the same manner as in S944 described with reference to FIG.

In the present embodiment, when an abnormality is detected in S1014, in S1022, the abnormality detection unit 434 transmits information indicating that the abnormality has been detected to the process control unit 440, and the process control unit 440 detects the abnormality. Information indicating that the work was done was transmitted to the worker terminal 214 or the administrator terminal 216. Then, the worker or the manager adjusts the settings of the device in which the abnormality is detected. However, the processing when an abnormality is detected in S1014 is not limited to this embodiment.

In another embodiment, when an abnormality is detected in S1014, in S1022, the abnormality detection unit 434 transmits information indicating that the abnormality has been detected to the operation plan determination unit 424. Upon receiving the information indicating that the abnormality has been detected, the operation plan determination unit 424 executes a process for updating the operation plan. For example, the operation plan determination unit 424 executes a process simulation based on a utility supply plan, a product production plan, and the current operation status of each device. As a result, a new operation plan (sometimes referred to as an updated operation plan) can be determined. If it is not possible to create an operation plan under reasonable conditions according to the current utility supply plan, the operation plan determination unit 424 may send information to the management server 110 indicating that it does not agree with the supply plan. ..

After that, the operation plan determination unit 424 transmits the updated operation plan to the process control unit 440. The process control unit 440 automatically changes the settings of each device based on, for example, the updated operation plan. When there is a device whose setting cannot be changed automatically, the process control unit 440 may send an instruction for changing the setting of the device to the worker terminal 214 or the administrator terminal 216. As a result, the worker or the manager can adjust the settings of the device according to the instruction from the process control unit 440.
