FIG. 1 shows a schematic configuration of an estimation system according to this embodiment. This estimation system is provided in association with an equipment database (equipment information storage means) 1 that stores the configurations (equipment specifications) of various water treatment equipment constructed using a plurality of types of equipment, and the equipment database 1. A history database 2 for storing the maintenance date and maintenance items of each water treatment facility, and its failure history and the like.
In the equipment database 1, the configuration (equipment specifications) of the existing water treatment equipment installed at each of a plurality of customers,
For example, it is needless to say that the management ID is added to each and stored, and as will be described later, the configuration (equipment specifications) of the water treatment equipment newly designed according to the customer specifications is also stored.

Further, the estimation system stores the specifications, service life, and maintenance frequency information of a plurality of types of equipments (filtration filters, boilers, heat exchangers, etc.) for constructing various water treatment equipments. The equipment database (equipment information storage means) 3 and the cost database (expense storage means) 4 that stores the unit price of the equipment (price of equipment) related to replacement or maintenance of each equipment and the construction cost thereof are provided. ing.

The estimation processing unit 10 composed of a computer system searches each of the databases 1, 2, 3 and 4 in accordance with the estimation / facility information given from the information input unit 5, and basically specifies the designated water treatment. A function (maintenance plan creating means) of extracting a maintenance item of equipment and formulating a maintenance plan for a predetermined period according to the maintenance item, and based on this maintenance plan, for example, referring to the cost database 4 A function (maintenance cost calculation means) for calculating the maintenance cost of the water treatment facility by accumulating the costs involved is provided. Further, the quotation processing unit 10 has a function (payment plan creating means) for formulating a payment plan for maintenance expenses over a predetermined period as described later.

More specifically, the estimation processing unit 10 searches the facility database 1 for information on a plurality of facility devices that constitute the water treatment facility designated via the information input unit 5, and obtains these information. A maintenance item extracting means 11 is provided for searching the equipment database 3 for the service life of each equipment and the like, and ascertaining equipment and equipment requiring maintenance in a predetermined maintenance period and their maintenance times as maintenance items. .
This maintenance item is extracted within a predetermined maintenance target period (estimated period) determined based on, for example, the operation start date of the water treatment facility or the date of maintenance that can be acquired from the history database 2. This is done by determining whether or not the equipment is a required equipment.
Further, the estimation processing unit 10 uses the cost database 4 for each maintenance item obtained by the maintenance item extracting means 11.
And a maintenance cost calculating means 12 for determining a maintenance cost including an item unit price and a construction cost required for maintenance (maintenance such as repair / replacement) of the maintenance item (facility equipment).

The maintenance cost thus obtained is given to the estimate creating means 13 together with the information on the maintenance item,
The estimate creation means 13 creates an estimate (individual estimate) of the cost required to maintain the equipment specified by the maintenance item. This quotation is presented to the user (equipment manager) who operates the water treatment facility through the quotation presenting unit 6.

In addition to the operating condition storing means 7 which can be rewritten from the information input section 5 such as the amount of raw water treated in the water treatment facility (for example, m ³ / day) and water quality data, the operating condition storing means is provided. It is preferable to include maintenance frequency calculation means 8 for calculating the data in the equipment database 3, that is, the maintenance frequency and the like based on the data stored in 7, and updating the data in the equipment database 3. If the storage unit 7 and the calculation unit 8 are provided, the maintenance frequency and the service life change depending on the raw water load, and the accuracy of estimating the maintenance cost for the filtration filter, the ion exchange resin, or the like can be improved. It is effective.

On the other hand, when the plurality of maintenance items with different maintenance times are required, the estimation processing unit 10 includes a maintenance plan creating means 14 for creating a maintenance plan according to these maintenance items. This maintenance plan creating means 14 is, for example, when the operation period of the water treatment facility is set to 10 years,
By classifying the maintenance items required for each management period defined as the first year, the second year, the third year, etc., and organizing the maintenance contents (maintenance items) to be executed in each year. , Make a maintenance plan for it.

When the maintenance plan of the water treatment facility is prepared in this way, the above-mentioned estimate preparing means 13 determines the maintenance required for each maintenance item in the maintenance cost calculating means 12 according to this maintenance plan. Costs are totaled for each management period, and an estimate (general estimate) for maintenance of the water treatment facility over a predetermined period is created. This estimate is presented to the user (equipment manager) who operates the water treatment facility via the estimate presenting unit 6 together with the maintenance plan.

In addition to the basic estimate processing function described above, the estimate processing section 10 also includes a payment plan preparation means 15 for preparing a payment plan for expenses associated with maintenance of the water treatment facility for a long period of time. This payment plan preparation means 15 pays attention to the total maintenance cost over a predetermined period instead of generally paying the maintenance cost each time the water treatment facility is maintained, and paying the total amount. A plan for dividing and paying a plurality of times within the predetermined period is created. That is, this payment plan is such that when the water treatment facility is operated for a long period of time, the maintenance cost will gradually increase, and if the maintenance cost is settled each time, the monetary amount that was relatively light at the initial stage. In order to prevent the financial burden from increasing gradually, for example, it plays a role of adjusting the financial burden to be almost constant.

Specifically, the payment plan preparation means 15 has a function of calculating the total amount of the maintenance cost for the predetermined period calculated by the estimation preparation means 13. Then, according to the payment pattern selected and designated by the payment pattern selection unit 16, by distributing the total maintenance cost of the water treatment facility over a predetermined period, for example, every year, a facility manager (user of the water treatment facility). ) Creates a payment plan in which maintenance expenses to be paid to the maintenance manager (maintenance company) are dispersed by year.

Incidentally, in the case of the split payment pattern, when the maintenance cost over a predetermined period increases year by year as shown in FIG. 2, the total maintenance cost shown as the shaded area is calculated as It is set as a split payment pattern Y that is leveled as an almost constant amount for each. In addition, this installment payment pattern increases maintenance costs in the early stage when expectations for water treatment equipment are high, and expects that the specifications of the water treatment equipment will become old in a few years and the expectation level will decrease. It is set as a split payment pattern Z or the like that gradually reduces the maintenance cost.

The setting of such a divided payment pattern is as follows.
For example, it is performed by selecting one of a plurality of types of divided payment patterns Y, Z, ... Prepared in advance. At this time, it is also possible to variably set the installment payment pattern itself (the tendency of change in payment amount). Then, a maintenance cost payment plan created in accordance with such an installment payment pattern is presented to the user (equipment manager) who operates the water treatment facility via the estimate presentation unit 6.

FIG. 3 shows an example of a schematic processing procedure of the maintenance cost estimation system having the above-mentioned functions. As shown in this processing procedure, in the present system, if the user name or equipment ID is input from the information input unit 5 and the water treatment equipment to be subjected to the estimation processing is specified [Step S
1], by searching the equipment database 1, the equipment that constructs the water treatment equipment is obtained [step S2]. By searching the equipment database 3 for each specified equipment, it becomes possible to obtain information on the service life and maintenance frequency of the equipment [step S3].

Thereafter, according to the maintenance estimation period given from the information input unit 5, it is determined whether or not there is equipment requiring maintenance within the estimation period. Then, for the equipment requiring maintenance within the estimated period, the equipment name and the maintenance time are extracted as maintenance items [step S4]. At this time, when a plurality of maintenance items with different maintenance periods are required, a maintenance plan for a predetermined period is created as described above [step S5]. And the cost database 4 for each of the above maintenance items
, The maintenance cost is calculated [step S6], and if there are a plurality of maintenance items, the total maintenance cost is calculated [step S7].

When the facility equipment to be maintained and the maintenance cost are obtained as described above, an estimate sheet is prepared in which the equipment name and the maintenance cost are listed in the form of a list according to the maintenance items described above. Step S8], which is presented to the user. If the estimated period is long, a maintenance expense payment pattern is set as necessary [step S9], and a total payment expense installment payment plan is created according to the payment pattern [step S10]. ], And presents this to the user.

Thus, according to the quotation processing system configured as described above, by inputting the user name, equipment ID, etc., and designating (specifying) the water treatment equipment to be the quotation related to maintenance, the input The equipment database 1 is searched according to the information to find a plurality of equipment devices that make up the water treatment equipment, and by searching the equipment database 3, the service life of these equipment devices is found. Then, according to the information such as the service life, it is determined whether or not there is equipment to be maintained within a predetermined maintenance target period from the operation start date of the water treatment facility or the last maintenance date shown by the history database 2. Then, the maintenance item is extracted, and the cost is calculated for the maintenance item by referring to the cost database 4.

As a result, by simply specifying the water treatment facility by using the user name, facility ID, etc., it is possible to easily obtain the item (facility equipment) to be maintained and the cost required for the maintenance of the water treatment facility. Is possible. When water treatment facilities are to be maintained for a long period of time, a maintenance plan for the maintenance period is created and an estimate based on this maintenance plan is created. It is necessary and the maintenance cost at that time can be easily arranged and calculated. Therefore, it is possible to make an effective operation plan of the water treatment facility according to the maintenance plan and the estimate thereof.

Further, according to the present system, the installment payment plan of the cost can be created under various payment patterns according to the total amount of the estimated cost over a long period of time. Therefore, it is possible to equalize the operation cost by paying the maintenance cost that accompanies the operation of the water treatment facility in advance in consideration of the financial burden expected to increase in the future. The effect such as is achieved. Therefore, even if the water treatment facility is operated for a long period of time, it is possible to prevent the occurrence of enormous maintenance costs beyond the expectation in the future. To be

In other words, in anticipation of maintenance expenses required in the future, the maintenance expenses required monthly or yearly can be leveled, and maintenance contracts with reduced financial burden can be concluded. Becomes Further, it is possible to easily prepare an operation plan of the water treatment facility according to the circumstances of the driver (customer) side, in particular, a financial plan for the cost required for the operation can be easily produced.

The present invention is not limited to the above embodiment. Here, the leveling of the operating cost (maintenance cost) in the water treatment facility has been described as an example, but the leveling of the operating cost in other facilities can be similarly applied. Further, the period for which the estimation process is performed may be determined in consideration of the service life of the equipment and the number of years of operation. Further, various payment patterns can be set, and the point is that various modifications can be made without departing from the scope of the invention.
