Description

The present invention relates to a contract charge calculation device and a contract charge calculation method.

Conventionally, a customer who uses a water treatment facility purchases the water treatment facility by concluding a sales contract between the water treatment facility supplier and the customer. In the sales contract, the water treatment facility becomes the customer's asset, and the customer manages the operation of the water treatment facility. In addition, when the customer wants to request a water treatment equipment contractor for regular patrol inspection and equipment maintenance, he / she requests the water treatment equipment contractor to maintain the water treatment equipment by concluding a maintenance contract separately from the sales contract. If you want to request the water treatment equipment contractor to manage the operation of the equipment together with the maintenance, request the water treatment equipment contractor to maintain and manage the water treatment equipment by concluding an operation management contract instead of the maintenance contract. In this way, the customer pays the contract fee of the sales contract and the contract fee of the maintenance contract and the operation management contract to the water treatment equipment supplier.

In recent years, water supply contracts have been used instead of sales contracts (see, for example, Non-Patent Document 1). In the water supply contract, the water treatment equipment supplier installs the water treatment equipment in the customer's facility as an asset of the contractor, supplies the treated water to the customer, and charges according to the amount of water supplied to the customer. In the case of a water supply contract, the customer does not have to purchase water treatment equipment, so the initial cost can be reduced.

The maintenance contract for water treatment equipment is based on the design conditions of the water treatment equipment, a certain maintenance period (for example, one year, etc.) is decided, and the patrol frequency, inspection items, parts replacement, etc. are planned in advance. , Has signed an annual contract. Then, when it is time for inspection, consumable parts and aging equipment that have been scheduled in advance are replaced. Similarly, in the operation management contract and water supply contract of the water treatment facility, the contract amount is calculated based on the design conditions of the water treatment facility and the contract is concluded.

However, in reality, the operating conditions of the water treatment equipment differ depending on the customer's facility, and the operation is not always performed according to a predetermined plan. As a result, it is assumed that there may be a discrepancy between the contract details of the originally planned operation plan and the actual operation situation. For example, if the water treatment facility is operated more than originally planned, there are cases where the amount of money specified in the original contract cannot be covered. In this case, either the customer or the water treatment equipment supplier will bear the shortfall. In addition, for example, if the water treatment facility is not operated more than originally planned, there are cases where maintenance is not required as much as the contents of the original contract. In this case, the customer is paying the contract fee for unnecessary maintenance.
As described above, the conventional method has a problem that the contract fee cannot be determined based on the operating condition of the water treatment facility.

In view of the above circumstances, an object of the present invention is to provide a technique capable of determining a contract fee based on the operating status of a water treatment facility in a contract in which a contract fee for maintenance of the water treatment facility is incurred.

One aspect of the present invention is the water using a communication unit that receives the operation data of the water treatment unit constituting the water treatment facility from the water treatment facility and the operation data within the contract period among the received operation data. It is a contract charge calculation device including a control unit for deriving the operation status of the treatment facility and calculating the contract charge for the water treatment equipment based on the derived operation status.

One aspect of the present invention is the above-mentioned contract fee calculation device, in which the operation data includes data on the water quality of the water to be treated of the water treatment facility, and the control unit determines the water quality of the water to be treated. The contract fee is calculated so that the worse the deviation from the water quality range is, the higher the contract fee is, and the closer the water quality of the treated water is to the predetermined water quality range, the lower the contract fee is calculated.

One aspect of the present invention is the above-mentioned contract charge calculation device, and the control unit calculates and specifies the contract charge so that the worse the specific operating condition deviates from the predetermined condition range, the higher the contract charge. The contract fee is calculated so that the closer the operating condition is to the predetermined condition range, the lower the contract fee.

One aspect of the present invention is the contract charge calculation device, wherein the control unit has a first threshold value when the water treatment facility is always in operation or the ratio of the total operation time to the total stop time. In the above case, the contract fee is calculated so that the contract fee is high, and the operation time is less than the second threshold value or the ratio of the total operation time to the total stop time is less than the third threshold value (first threshold value). When the threshold value ≥ the third threshold value), the contract fee is calculated so that the contract fee is low.

One aspect of the present invention is the contract charge calculation device, and the control unit searches for a similar water treatment facility having a similar operating condition to the water treatment facility based on the operation data of the water treatment unit. , The operation status of the water treatment facility at a predetermined time in the future is predicted according to the operation status of the similar water treatment facility, and the contract fee is calculated based on the prediction result.

One aspect of the present invention is the contract charge calculation device, and the control unit increases the contract charge when the water quality of the water to be treated deviates from the predetermined water quality range and deteriorates as a result of the prediction. The contract fee is calculated as described above, and when the water quality is close to the predetermined water quality range and becomes good, the contract fee is calculated so that the contract fee is lowered.

In one aspect of the present invention, the communication step of receiving the operation data of the water treatment unit constituting the water treatment facility from the water treatment facility and the operation data of the received operation data at least within the contract period are used. It is a contract charge calculation method having a contract charge calculation step of deriving the operation status of a water treatment facility and calculating the contract charge of the water treatment equipment based on the derived operation status.

According to the present invention, it is possible to determine the contract fee based on the operating status of the water treatment facility in the contract in which the contract fee for the maintenance of the water treatment facility is generated.

At this time, the control unit 24 acquires all the contract period records having the same customer ID if the customer IDs are the same even if the contract numbers are different. Then, the control unit 24 refers to the contract period item of the acquired contract period record, and acquires the period from the contract start time to the present time among the periods registered in the contract period item as the operation period.

The control unit 24 confirms the design value of the unit 11 constituting the water treatment facility 10 confirmed in the process of step S102 by using the design condition database 258 (step S105). The control unit 24 inputs the equipment configuration of the customer's water treatment equipment 10 and the design value of the unit 11 constituting the water treatment equipment 10 and executes the appropriate operation simulation program 252 to ensure that the water treatment equipment 10 is appropriate. The operating range is derived for each unit 11 (step S106).

The control unit 24 acquires the operation data of the unit 11 provided in the water treatment facility 10 by using the device operation database 259 (step S107).
The control unit 24 uses the regional characteristic database 260 to acquire regional characteristic data of the location where the customer's water treatment facility 10 identified by the customer ID is installed (step S108).

The control unit 24 inputs the operation data of the unit 11 and the characteristic data of the area, and executes the appropriate situation simulation program 253 to operate the unit 11 provided in the water treatment facility 10 from the start of the contract to the present time. Derivation of the situation (step S109). However, if the water quality data or operation data of the water to be treated before the contract period is acquired, the control unit 24 calculates the operation status by utilizing the data because the accuracy of the simulation is improved.
FIG. 14 is a conceptual diagram showing an operating state of the unit 11 provided in the water treatment facility 10. FIG. 14 shows the operating status of one unit 11 as an example. In FIG. 14, the horizontal axis represents time and the vertical axis represents water quality index. Here, the water quality index is an index indicating the quality of the water to be treated of the water treatment facility 10. The water quality index may be an index of individual water quality items, or may be an index including a plurality of water quality items (for example, pH, turbidity, electrical conductivity, hardness, etc.). In addition, the water quality index I represents the middle of good and bad water quality. FIG. 14 (A) is a diagram showing an example in the case where the variation in water quality is large, and FIG. 14 (B) is a diagram showing an example in the case where the variation in water quality is small.

The appropriate range values shown in FIGS. 14 (A) and 14 (B) represent the appropriate range values obtained by executing the appropriate operation simulation program 252. Further, the line 41 shown in FIG. 14 (A) and the line 42 shown in FIG. 14 (B) represent the transition lines of the operating conditions obtained by executing the appropriate situation simulation program 253. As shown in FIG. 14 (A), in line 41, a bad period is observed in which the water quality of the water to be treated deviates from the appropriate range value.
On the other hand, as shown in FIG. 14 (B), in line 42, the water quality of the water to be treated does not deviate from the appropriate range value, and a period close to the middle I of the appropriate range value is observed. The fact that it is close to the middle I of the appropriate range value indicates that the water quality of the water to be treated is good. If the quality of the water to be treated deviates from the appropriate range value and is poor, it is necessary to perform excessive treatment in the unit 11. In this case, it is expected that the maintenance and replacement period of parts will be shortened because the processing load is applied to the unit 11 as compared with the case where the water quality of the water to be treated is good. Therefore, the control unit 24 calculates the contract fee so that the contract fee becomes high when the water quality of the water to be treated deviates from the appropriate range value and is bad. Further, the control unit 24 calculates the contract fee so that the contract fee becomes lower as the operation is performed in a state closer to the appropriate range value, particularly in a state closer to the intermediate I of the appropriate range value.

The control unit 24 uses the operation status determination database 261 to diagnose the operation status of each unit 11 from the contract start time to the present time (step S110). Specifically, first, the control unit 24 multiplies the actual operation value by the regional characteristic correction coefficient. Next, the control unit 24 calculates the appropriate rate based on the multiplication result and the appropriate range value. Then, the control unit 24 diagnoses the operating status from the contract start time to the present time for each unit 11 by performing these processes for each determination period. By performing such processing, it is possible to confirm the period during which the actual operation value falls within the appropriate range value, the period during which the actual operation value does not fall within the appropriate range value, and the like.

Then, the control unit 24 calculates the contract fee using the contract fee database 262 (step S111). Specifically, the control unit 24 calculates the contract fee for each period based on the standard contract fee according to the appropriate rate for each contract period. Then, the control unit 24 calculates the contract fee by adding all the contract fees for each period.

According to the contract fee calculation system 100 configured as described above, the contract fee is calculated based on the water quality of the water to be treated by each unit 11 in the water treatment facility 10. For example, if the quality of the water to be treated deviates from the appropriate range value and is poor, it is necessary for the unit 11 to perform excessive treatment. In this case, it is expected that the maintenance and parts replacement period will be earlier because the processing load is applied to the unit 11 as compared with the case where the water quality of the water to be treated is good. Therefore, the contract charge calculation device 20 calculates the contract charge so that the contract charge becomes higher when the water quality of the water to be treated deviates from the appropriate range value and is bad. On the contrary, the closer the quality of the water to be treated is to the specified water quality range, the lower the treatment load. Therefore, use the standard contract fee, or if the water quality is extremely good, set the contract fee so that the contract fee is lower than the standard contract fee. calculate. Therefore, it is possible to determine the contract fee based on the operating status of the water treatment facility.

(Second Embodiment)
In the second embodiment, the contract charge calculation device calculates the contract charge for each customer based on the specific operating conditions of the unit.
The difference between the contract charge calculation device 20 in the second embodiment and the contract charge calculation device 20 in the first embodiment is the method for calculating the contract charge by the control unit 24. Since the other points are the same as those of the first embodiment, only the differences will be described below.

The control unit 24 in the second embodiment calculates the contract fee so that the worse the specific operating condition of each unit 11 in the water treatment facility 10 deviates from the predetermined condition range, the higher the contract fee is, and the water treatment is performed. The contract fee is calculated so that the closer the specific operating condition of each unit 11 in the facility 10 is to the predetermined condition range, the lower the contract fee. Here, "specification" represents an item that affects the load of the unit 11 and changes the maintenance time. The specific operating conditions may be determined by the operating time of each unit 11, or may be determined by the time ratio of the repetition of operation and stop. For example, the control unit 24 charges a contract fee so that the contract fee is high when the water treatment facility 10 is constantly operated or when the ratio of the total operation time to the total stop time is equal to or greater than the first threshold value. Is calculated. Further, the control unit 24 determines that the operating time of the water treatment facility 10 is less than the second threshold value or the ratio of the total operating time to the total stopping time is less than the third threshold value (first threshold value ≥ third threshold value). In some cases, the contract fee is calculated so that the contract fee is low.

FIG. 15 is a conceptual diagram showing an operating state of the unit 11 provided in the water treatment facility 10. FIG. 15 shows the operating status of one unit 11 as an example. In FIG. 15, the horizontal axis represents time and the vertical axis represents water quality index. In addition, the water quality index I represents an intermediate level between good and bad water quality. FIG. 15A is a diagram showing an example of an operating condition of the unit 11 which is constantly operating, and FIG. 15B is a diagram showing an example of an operating condition of the unit 11 which repeatedly operates and stops. ..

The appropriate range values shown in FIGS. 15A and 15B represent the appropriate range values obtained by executing the appropriate operation simulation program 252. Further, the line 43 shown in FIG. 15A and the line 44 shown in FIG. 15B represent the transition lines of the operating conditions obtained by executing the appropriate situation simulation program 253. As shown in FIG. 15 (A), it can be seen that the line 43 is in a constant operation state without a stop period.

On the other hand, as shown in FIG. 15B, it can be seen that the state of the operation period and the stop period is repeated on the line 44. In the case of constant operation, it is assumed that the deterioration of the unit 11 is faster than that of the unit 11 having a short operation time. Further, even when the unit is not always operated, if the total operation time is long, it is assumed that the deterioration of the unit 11 is faster than that of the unit 11 in which the total operation time is short. Therefore, the contract charge calculation device 20 calculates the contract charge so that the contract charge is high when the product is always operated or when the ratio of the total operation time to the total stop time is equal to or more than the first threshold value. , If the operating time of the water treatment facility 10 is less than the second threshold value or the ratio of the total operating time to the total stopping time is less than the third threshold value (first threshold value ≥ third threshold value), the contract fee Calculate the contract fee so that

According to the contract charge calculation system 100 according to the second embodiment configured as described above, the contract charge is calculated based on the operating conditions of each unit 11 in the water treatment facility 10. Therefore, it is possible to determine the contract fee based on the operating status of the water treatment facility.

The similar customer represents, for example, a customer whose contract period, production item, classification, and any two or more of the configurations of the units 11 constituting the water treatment facility 10 are similar. FIG. 17 is a diagram showing an example of a similar customer database 263. The similar customer database 263 has a plurality of records (hereinafter referred to as "similar customer records") representing information about similar customers. The similar customer record has each value of customer ID, similar customer A, and similar customer B. The customer ID represents information for uniquely identifying the customer.

In FIG. 18, the appropriate rate R of the customer, the appropriate rate RA of the similar customer A, and the appropriate rate RB of the similar customer B are registered. The appropriate rate correction coefficient K represents a correction coefficient for correcting the appropriate rate. The appropriate rate correction coefficient is a coefficient calculated from the appropriate rate of operation of similar projects, and can be calculated as (RA + RB) / 2, for example, using the appropriate rates RA and RB on the same day. The corrected appropriate rate can be calculated by, for example, R × K using the appropriate rate R and the appropriate rate correction coefficient K for the customer this time. The contract fee is calculated using the calculated appropriate rate after correction.

FIG. 19 is a flowchart showing the flow of the contract charge calculation process by the contract charge calculation device 20a according to the third embodiment. Note that, in FIG. 19, the same processing as in FIG. 13 is designated by the same reference numerals as in FIG. 13, and the description thereof will be omitted.

The similar water treatment facility is another water treatment facility 10 having the same water treatment facility configuration, treated water characteristics, and treated water characteristics as the customer's water treatment facility 10 (for example, matching a predetermined ratio or more). It should be noted that the water treatment equipment configuration, the water treatment characteristics and the treated water characteristics do not necessarily have to be all similar, and the water treatment equipment 10 having only the water treatment equipment configuration similar may be used, or in addition to the water treatment equipment configuration. The water treatment facility 10 may have similar characteristics of the water to be treated and the characteristics of the treated water.

For the period when it becomes good near, the contract fee for each period is calculated so that the contract fee will be low. After that, the control unit 24a calculates the contract fee by adding all the contract fees for each period.
