BACKGROUND OF THE INVENTION
The present invention relates to a second-hand goods estimation system, a method thereof, and a program thereof for presenting a user with an estimated price when taking second-hand goods from a user.
[0002]
[Prior art]
In recent years, a system has been proposed that presents an estimated price when a used item is collected from a user to the user. For example, Patent Document 1 discloses a recycling support method using a computer network. Here, when a user specifies a used item on an estimate input screen and selects a button for presenting an estimated amount, the server computer Calculate the estimated amount of second-hand goods and send it to the user computer. Non-Patent Document 1 discloses a computer trade-in service for a user who newly purchases a product. Here, a user can use a CPU, memory, HDD, etc. of a used computer on an information input screen. When an estimate result is requested after inputting information related to the specification, an estimated trade-in amount of the used computer is presented from the server side.

[Problems to be solved by the invention]
By the way, when a user wants a trader to pick up second-hand goods, it can be broadly divided into purchases of new products. In some cases, the used items that have been used up to now are no longer needed. In this specification, the former takes over the used items, and the latter is called the “trade-in”. . As described above, there are two types of trade-in and purchase of second-hand goods, but in Patent Document 1 and Non-Patent Document 1, only one of them is considered, and the user trades in the trade-in. There was a problem that it was difficult to become an index when he was wondering whether he / she would receive or purchase. Further, from the side of collecting used items, it is desirable to use the opportunity to collect used items from the user to stimulate product purchase motivation.
[0005]
The present invention has been made in view of such a problem, and a used product estimation system capable of presenting an index as to whether a user should take a trade-in or purchase when a user receives a used product. And to provide the program. It is another object of the present invention to provide a second-hand goods estimation system, a method thereof, and a program for the same, which can use the opportunity to pick up second-hand goods from a user and stimulate a product purchase motivation.
[0006]
[Means for solving the problems and their functions and effects]
In order to achieve at least one of the above objects, the present invention employs the following means.
[0007]
A first aspect of the present invention is a used product estimation system that presents an estimated price when taking a used product from a user to a user computer,
When receiving a request for quotation of the second-hand goods and information necessary for quotation for the second-hand goods from the user computer, the estimated trade-in price when the second-hand goods take-off is a trade-in involving purchase of goods, and An estimated price determining means for determining an estimated purchase price based on the estimated necessary information in the case where the second-hand goods are purchased without the purchase of the product;
Estimate information transmitting means for transmitting estimate information including the trade-in estimated price determined by the estimated price determining means and the purchase estimated price to the user computer;
It is equipped with.
[0008]
In this second-hand product quotation system, when a request for a second-hand product quotation and necessary information necessary for the second-hand product quotation are received from a user computer, the estimated trade-in price and the estimated purchase price of the second-hand product are estimated. The trade-in estimated price and the purchase estimated price are transmitted to the user computer. Thus, the user can compare the estimated trade-in price with the estimated purchase price, and can be used as an indicator of whether the user should take out the trade-in or purchase when the second-hand goods are received.
[0009]
Note that “second-hand goods” refers to goods that are not new, such as goods that have been used several times, or goods that have not been used and the date has passed. Further, the estimated price determination means may receive the necessary information for quotation at the same time as the request for quotation of used goods, or may receive the request for quotation of used goods and the information necessary for estimation separately.
[0010]
In the second-hand goods estimation system of the present invention, the estimated price determination means may determine the estimated price for trade-in and the estimated price for purchase so that the estimated price for trade-in is more advantageous than the estimated price for purchase. . In this way, it is expected that the user will consider purchasing the product as much as possible to collect the used product at the estimated trade-in price. That is, it is possible to evoke merchandise purchase intentions by taking advantage of the opportunity to collect second-hand goods from the user.
[0011]
In the second-hand product estimation system of the present invention, the estimated price determination means determines the purchase price so that the estimated price of trade-in is more advantageous than the estimated price of purchase based on the estimated price of purchase. After determining the trade-in price, or after determining the trade-in price, the purchase price is determined based on the trade-in price so that the trade-in price is more advantageous than the purchase price. Also good. The estimated purchase price and the estimated trade-in price may be determined individually, but after determining the estimated purchase price, the estimated trade-in price may be determined based on the estimated purchase price, or the estimated trade-in price. If the purchase estimated price is determined based on the estimated trade-in price after determining the price, the estimated trade-in price can be easily determined to be more advantageous than the estimated purchase price. Specifically, after the estimated purchase price is determined, the trade-in estimated price is calculated as a function of the estimated purchase price, or after the estimated trade-in price is determined, the estimated purchase price is calculated as a function of the estimated trade-in price. For example, the former may be calculated by adding a predetermined offset price (> 0) to the estimated purchase price or multiplying by a predetermined coefficient (> 1), and the latter may be a trade-in price. The estimated purchase price may be obtained by adding a predetermined offset price (<0) to the estimated price or multiplying by a predetermined coefficient (<1). The predetermined offset price or the predetermined coefficient may be a constant value or a value determined according to the price.
[0012]
In the used product estimation system of the present invention, the estimated price determination means may determine a minimum value and a maximum value of the estimated purchase price and a minimum value and a maximum value of the estimated price of trade-in. In this way, when comparing the trade-in estimated price and the purchase estimated price, the user can compare the minimum value or the maximum value of both, so it is more useful as an index.
[0013]
In the used product estimation system of the present invention, the estimate information transmitting means is selected when the user wishes to purchase at the purchase estimated price in addition to the purchase estimated price and the trade-in estimated price as the estimated information. An estimate screen including a purchase selection unit to be selected and a trade-in selection unit to be selected when the user wishes to trade in at the trade-in estimated price may be transmitted to the user computer. In this way, the system side can recognize the user's intention to purchase the product at the estimated purchase price without purchasing the product when the purchase selection unit is selected, and purchases the product when the trade-in selection unit is selected. Recognize the user's willingness to collect at the estimated trade-in price. For example, when the purchase selection unit is selected, the user may be asked for information necessary to purchase second-hand goods, and when the trade-in selection unit is selected, the user may move to a product purchase site.
[0014]
In this way, when the estimate information transmitting means transmits the estimate information including the purchase selection unit and the trade-in selection unit to the user computer, the user selects the trade-in selection unit from the user computer. A trade-in content storage unit that stores in the storage unit the trade-in content including the necessary information for quotation and the trade-in estimated price when the user wishes to trade in, and a product from the user computer A trade-in content confirmation unit that reads out and transmits the trade-in content stored in the storage unit and confirms whether or not the user performs a trade-in with the trade-in content May be provided. In this way, when a user purchases a product and trades in second-hand goods, it is only necessary to confirm the trade-in details when the previous quotation was requested. There is no need for trouble.
[0015]
In the used product estimation system of the present invention, the estimated price information transmission means comprises purchase determination means for determining whether or not the estimated purchase price determined based on the necessary information for estimation is within a predetermined purchaseable price range, When the purchase determination means determines that the estimated purchase price is not in the purchaseable price range, the estimated information not including the estimated purchase price may be transmitted to the user computer. In other words, if the second-hand goods are not worth buying alone, the estimated purchase price is not presented. The price presents. In this way, it is expected that the user wants to collect the used goods at the estimated trade-in price and considers the purchase of the goods. In other words, it is possible to stimulate the purchase of merchandise using the opportunity to collect used items from the user.
[0016]
As described above, when the estimate information transmission unit transmits the estimate screen including the purchase selection unit and the trade-in selection unit to the user computer, the estimate information transmission unit does not include the purchase estimated price. When transmitting the estimate information to the user computer, the estimate screen may be transmitted without including the purchase selection unit, or may be transmitted including the purchase selection unit in a state where the user cannot select the estimate screen. . By doing so, it is possible to avoid a situation in which the user selects the purchase selection unit by mistake even though the estimated purchase price of the second-hand goods is not presented.
[0017]
In the second-hand goods estimation system of the present invention, the estimated price determination means receives information on parts contained in the second-hand goods from the user computer as a request for second-hand goods quotation and necessary information necessary for the second-hand goods quotation. Then, the trade-in estimated price and the purchase estimated price may be determined based on information on the parts. In this way, the value can be determined according to the parts included in the used product.
[0018]
A second aspect of the present invention is a used product estimation method for presenting an estimated price when taking a used product from a user to a user computer,
(A) When the server-side computer receives from the user computer the quotation request for the second-hand goods and the information necessary for quotation for the second-hand goods quotation, the second-hand goods take-off is a trade-in with purchase of goods. Determining an estimated trade-in price in the case of a purchase price and an estimated purchase price in the case where the second-hand goods take-off does not involve purchase of a product based on the estimated information,
(B) the server-side computer sending estimate information including the trade-in estimated price determined in step (a) and the purchase estimated price to the user computer;
Is included.
[0019]
In this second-hand goods estimation method, when a request for a second-hand goods quotation and necessary information necessary for the second-hand goods quotation are received from a user computer, the estimated trade-in price and the estimated purchase price of the second-hand goods are estimated. The trade-in estimated price and the purchase estimated price are transmitted to the user computer. Thereby, the user can compare the trade-in estimated price with the buy-in estimated price, and can be used as an index of whether the user should take out the trade-in or purchase when the second-hand goods are collected. The server side computer may be one or a plurality of computers.
[0020]
A third aspect of the present invention is a second-hand goods estimation program for causing a user computer to present an estimated price when taking second-hand goods from a user,
(A) When a request for quotation of the second-hand goods and information necessary for quotation for the second-hand goods are received from the user computer, a trade-in quotation in the case where the pick-up of the second-hand goods is a trade-in involving purchase of a product Determining a price and an estimated purchase price in the case where the pick-up of the second-hand goods is a purchase that does not involve the purchase of a product, based on the estimate necessary information;
(B) transmitting estimate information including the estimated price for trade-in and the estimated price for purchase determined in step (a) to the user computer;
Is a second-hand product estimation program for causing a server-side computer to execute.
[0021]
This used product estimation program may be recorded on a computer-readable recording medium (for example, hard disk, ROM, FD, CD, DVD, etc.) or via a transmission medium (communication network such as the Internet or LAN). It may be distributed from one computer to another, or may be exchanged in any other form. If this server program is executed by the server-side computer, the server-side computer receives a request for quotation of second-hand goods and information necessary for quotation for the second-hand goods from the user computer. The purchase price and the purchase price are determined based on the necessary information, and the trade-in price and the purchase price are transmitted to the user computer. Thereby, the user can compare the trade-in estimated price with the buy-in estimated price, and can be used as an index of whether the user should take out the trade-in or purchase when the second-hand goods are collected. The server side computer may be one or a plurality of computers.
[0022]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram showing a schematic configuration of a used product estimation system 10 of this embodiment, and FIG. 2 is an explanatory diagram of various databases stored in a data storage device of a database server.
[0023]
A used product estimation system 10 according to the present embodiment includes a web server 12 and a database server 14, which are connected to each other via a network cable 18.
[0024]
The web server 12 is a server that establishes a used product quotation site that presents an estimated price when taking a used product of a personal computer owned by a user. The web server 12 is a server that serves as a request window for the user computer 40 connected via the Internet 20, creates a response content by itself according to the request content received from the user computer 40, and transmits the response content to the user computer 40. Or, the estimate necessary information received from the user computer 40 is passed to the database server 14, the purchase price is calculated by the database server 14, the calculation result is received, and the response content is created from the calculation result and transmitted to the user computer 40. It has a function to do. Note that the necessary information for estimation is information on the types and performances of the components constituting the used product of the personal computer, which will be described in detail later.
[0025]
The data storage device 16 is connected to the database server 14 and stores a component price table in which component names, types, and prices of components of the personal computer are associated with each other as shown in FIG. The component names of personal computer components include CPU, memory, HDD, FDD, CD-ROM, LAN card, manual, and packing box. Among these, the CPU is determined by the processor name and clock frequency. The price is determined for each type, and the type of memory and HDD is determined by the capacity, and the price is determined for each type. Although not shown in the figure, the type of CD-ROM is determined according to the function (DVD readable or writable, etc.) and the price is determined for each type, and FDD, LAN card, manual, and packing box are provided instead of the type. The price is determined according to whether or not.
[0026]
The database server 14 is connected to the data storage device 16 and searches the data storage device 16 on the basis of the information necessary for estimation of the personal computer received from the user computer 40 via the web server 12, and the used price of each component is obtained. It has a function of calculating the total amount as the maximum purchase price PAmax and passing it to the web server 12.
[0027]
The user computer 40 is a well-known general-purpose personal computer used by an individual or a corporation, and can access a used product quotation site established by the web server 12 via the Internet 20 by an installed web browser. Further, the user computer 40 displays various screen information on the display 42.
[0028]
Next, operation | movement of the used article estimation system 10 of this embodiment is demonstrated. FIG. 3 is an explanatory diagram showing the communication state of the web server 12, the database server 14, and the user computer 40 in time series.
[0029]
First, the user starts up a web browser of the user computer 40 and inputs a URL (Uniform Resource Locator) of a used product quotation site established by the web server 12. Then, the user computer 40 transmits an acquisition request for the top page of the used product quotation site to the web server 12 via the Internet 20 (step S100). Receiving this, the web server 12 transmits the top page screen of the used product quotation site to the user computer 40 via the Internet 20 (step S110), and the user computer 40 that has received this displays a top page screen (not shown) on the display 42. To display.
[0030]
Next, the user clicks an estimate request button provided on a top page screen (not shown). Then, the user computer 40 transmits an estimate request to the web server 12 via the Internet 20 (step S120). Receiving this, the web server 12 transmits an estimate required information input screen to the user computer 40 via the Internet 20 (step S130), and the user computer 40 receiving this displays the estimate required information input screen on the display 42. To do. Here, the estimation necessary information is information necessary for estimating a used product of a personal computer, and specifically, information relating to components of the personal computer. FIG. 4 is an example of an estimate required information input screen. Here, processor name and clock frequency for CPU, capacity for memory and HDD, function for CD-ROM (DVD readable and writable, etc.), presence / absence for FDD, LAN card, manual and packing box Select and input from the pull-down menu.
[0031]
Next, the user inputs information on each component on the estimate necessary information input screen, and clicks an “OK” button (see FIG. 4) provided on the screen. Then, the user computer 40 transmits the estimation necessary information to the web server 12 via the Internet 20 (step S140). Receiving this, the web server 12 transmits a request signal for the estimated purchase price together with the estimate necessary information to the database server 14 (step S150). Then, the database server 14 that has received this calculates the maximum purchase price PAmax of the estimated purchase price with reference to the parts price table (see FIG. 2) stored in the data storage device 16 based on the required estimate information. Specifically, the price associated with the CPU processor name and clock frequency, the price associated with the memory capacity, the price associated with the HDD capacity, etc. are read from the component price table illustrated in FIG. As shown in Equation 1, the total of these component prices is calculated as the maximum purchase price PAmax.
[0032]
[Expression 1]
PAmax = Σ (part price)
[0033]
After calculating the maximum purchase price PAmax in this way, the database server 14 transmits the maximum purchase price PAmax to the web server 12 (step S160). Then, the web server 12 that has received this executes an estimation screen creation processing routine shown in FIG. That is, the web server 12 first calculates the minimum value PAmin of the estimated purchase price and the maximum value PBmax / minimum value PBmin of the estimated trade price based on the maximum value PAmax of the estimated purchase price received from the database server 14 ( Step 210). An example of a calculation formula for obtaining each value is shown in Formula 2.
[0034]
[Expression 2]
PAmin = PAmax × k
PBmax = PAmax + α
PBmin = PBmax × k ′
(However, k <1, k ′ <1, α> 0)
[0035]
Subsequently, it is determined whether or not the maximum purchase price PAmax exceeds the threshold value P1 (step S220). This threshold value P1 is set to a value that is judged to be not worth buying alone for the used product estimation system 20 when the maximum value PAmax of the estimated purchase price is equal to or less than this threshold value P1. When PAmax exceeds P1, it is determined that the second-hand goods are worth buying without the purchase of goods, and also worth trade-in with the purchase of new goods. An estimate screen including an explanatory note, a minimum value PAmin / maximum value PAmax of a purchase estimated price, a minimum value PBmin / maximum value PBmax of a trade-in estimated price, and a purchase button / trade-in button / cancel button is created (step S230). ), And then the routine ends. An example of the estimate screen at this time is shown in FIG. The purchase / trade-in explanation is that the estimated purchase price is the estimated price without the purchase of a new product, and the estimated trade-in price is the estimated price with the purchase of a new product. Second-hand goods that do not work properly are not subject to purchase or trade-in, and the final purchase price or trade-in price is determined within the range from the lowest value to the highest value after the system has assessed the used goods. And second-hand property ownership will be transferred to the system when it arrives at the system (see “* Notes” in FIG. 6).
[0036]
On the other hand, when the maximum value PAmax of the estimated purchase price in step S220 is equal to or less than the threshold value P1, it is determined that the used product is not worth buying without the purchase of the product, but worth the trade-in with buying the product, Subsequently, it is determined whether or not the maximum value PBmax of the estimated trade-in price exceeds the threshold value P2 (step S240). This threshold value P2 is a value for which it is determined that it is not necessary for the second-hand goods estimation system 20 side to have a range of the second trade-in estimated price when the maximum value PBmax of the trade-in estimated price is less than or equal to this threshold value P2. Is set. When PBmax exceeds P2, it is determined that the second-hand product needs to present a trade-in estimate price with a purchase of a new product with a range, and the trade-in explanation and trade-in estimate An estimate screen including the minimum value PBmin / maximum value PBmax of the price and the trade-in button / cancel button is created (step S250), and then this routine is terminated. An example of the estimate screen at this time is shown in FIG. The trade-in explanation is that this second-hand product is low value and cannot be purchased without the purchase of the product and is only subject to trade-in with the purchase of the product. The final trade-in price is determined within the range from the lowest value to the highest value after the system has assessed the second-hand goods, and the ownership of second-hand goods is left to the system side. This means an explanation of the transfer to the system when it arrives (see “* Notes” in FIG. 7).
[0037]
On the other hand, when the maximum value PBmax of the estimated trade-in price is equal to or less than the threshold value P2 in step S240, it is determined that the used-goods estimation system 20 does not need to have a wide range of the estimated trade-in price of the used goods. The price is set to a fixed amount P2 (threshold value in step S240), and an estimate screen including a trade-in explanation, a trade-in estimated price P2, and a trade-in button / cancel button is created (step S260). Exit. An example of the estimate screen at this time is shown in FIG. The trade-in explanation at this time means that the second-hand goods of this time are low-value and cannot be purchased without purchasing the product, and are only eligible for trade-in with the purchase of the product. This means an explanation that the product is not subject to trade-in and that the ownership of the used product is transferred to the system when it arrives at the system (see “* Notes” in FIG. 8). In this case, the second-hand goods are traded at a fixed estimated trade-in price P2 without evaluating the second-hand goods. After the above quote screen creation processing routine is completed, the process returns to FIG. 3 and the web server 12 transmits the created quote screen to the user computer 40 (step S170). Receiving this, the user computer 40 displays the estimate screen on the display 42.
[0038]
At this time, if it is the estimate screen shown in FIG. 6, the user compares the purchase estimated price and the trade-in estimated price on the estimate screen, particularly compares the lowest value and the highest value of both prices, and makes a purchase. Click the “Purchase Request” button if you wish, click the “Trade Request” button if you wish to trade in, or click the “Cancel” button if you do not wish to trade in. Then, the user computer 40 sends a purchase request when the “Purchase Request” button is clicked, a trade-off request when the “Trade Request” button is clicked, and a cancel request when the “Cancel” button is clicked. It transmits to the web server 12 via 20 (step S180). Then, when the received signal is a purchase request, the web server 12 that has received this transmits to the user computer 40 a purchase necessary information input screen (not shown) for inputting information necessary for buying second-hand goods. When the signal is a trade-in request, the user computer 40 is connected to a product purchase site (not shown) where a new product can be purchased. When the received signal is a cancel request, a top page screen (not shown) is transmitted to the user computer 40. (Step S190). Here, purchase required information includes the user's address, address, telephone number, e-mail address, etc., and if the pickup destination of second-hand goods is different from the user's address, the address of the pickup destination, the name of the person in charge, the telephone Number etc.
[0039]
In addition, if it is the estimate screen shown in FIG. 7 or FIG. 8, the user read the precautions, and the second-hand goods this time were not subject to purchase because they were low value. If you wish to trade in, click the “Trade in” button. If you do not wish to trade in, click the “Cancel” button. Then, the user computer 40 transmits a trade-in request to the web server 12 via the Internet 20 when the “trade-in request” button is clicked and a “cancel” button is clicked (step S180). . Then, the web server 12 that has received the request connects the user computer 40 to a product purchase site where a new product can be purchased when the received signal is a trade-in request, and when the received signal is a cancel request. The top page screen is transmitted to the user computer 40 (step S190).
[0040]
Here, the correspondence between the components of the present embodiment and the components of the present invention will be clarified. The web server 12 and the database server 14 of the present embodiment correspond to the estimated price determining means of the present invention, the web server 12 corresponds to the estimated screen transmitting means and the purchase determining means, and the threshold value P1 is set for the maximum value PAmax of the estimated purchase price. The price range that exceeds is equivalent to the purchaseable price range. The contents of the estimate screen correspond to the estimate information, the purchase button corresponds to the purchase selection unit, and the trade-in button corresponds to the trade-in selection unit.
[0041]
In the second-hand goods estimation system 10 of this embodiment described in detail above, when a request for quotation of second-hand goods for a personal computer and necessary information necessary for the quotation are received from the user computer 40, the purchase price of the second-hand goods is calculated. When the minimum value PAmin / maximum value PAmax and the minimum value PBmin / maximum value PBmax of the estimated trade-in price are determined based on the necessary information for estimation, the estimated screen shown in FIG. Send to user computer. Thus, the user can compare the estimated trade-in price with the estimated purchase price, and can be used as an indicator of whether the user should take out the trade-in or purchase when the second-hand goods are received. In particular, when the user compares the estimated trade-in price with the estimated purchase price, the user can compare the lowest value or the highest value between the two, so that the user is more useful as an index.
[0042]
In addition, since the estimated trade-in price is set to be more advantageous than the estimated purchase price, the user is expected to consider purchasing the product as much as possible to collect the used goods at the estimated trade-in price. Is done. That is, it is possible to evoke merchandise purchase intentions by taking advantage of the opportunity to collect second-hand goods from the user.
[0043]
Further, after determining the maximum value PAmax of the estimated purchase price, the minimum value PAmin of the estimated purchase price, the maximum value PBmax and the minimum value PBmin of the estimated price of trade-in are determined based on the maximum value PAmax of the estimated purchase price. The estimated price can be easily determined to be more advantageous than the estimated purchase price.
[0044]
Furthermore, the used product estimation system 10 can recognize the user's intention to purchase the product at the estimated purchase price without purchasing the product when the purchase button is selected on the estimate screen of FIG. 6, and the trade-in button is selected. When a product is purchased, it is possible to recognize the user's intention that the product is purchased at the estimated price of trade-in.
[0045]
Further, when the maximum purchase price PAmax of the estimated purchase price is out of the purchase price range in step S220 of FIG. 5, the process proceeds to step S250 or S260 and the estimated purchase price is not presented as in the estimate screen of FIG. 7 or FIG. However, even in such a case, if the trade-in is accompanied by the purchase of the product, it is meaningful for the second-hand goods estimation system 10 side, so the trade-in estimated price is presented. It is expected to consider purchasing products that you would like to receive. In other words, it is possible to stimulate the purchase of merchandise using the opportunity to collect used items from the user. At this time, since the purchase button is not displayed, there is no possibility of selecting the purchase button by mistake.
[0046]
Further, since the estimated trade-in price and the estimated purchase price are determined based on the information on the parts included in the used goods, the value can be determined according to the parts included in the used goods.
[0047]
Needless to say, the present invention is not limited to the above-described embodiments, and can be implemented in various forms.
[0048]
For example, in the above-described embodiment, the price of each component of the personal computer is read from the parts price table, and the total price of the parts is set as the maximum purchase price PAmax, but the total price of the parts is the minimum price of the estimated purchase price. PAmax, PAmax, PBmax, PBmin may be obtained based on this minimum value PAmin, or the total price of parts is set as the maximum value PBmax of the trade-in estimated price, and PAmax, PAmin, PBmin may be obtained, or PAmax, PAmin, PBmax may be obtained based on the minimum value PBmin of the total price of parts as the minimum value PBmin of the trade-in estimated price. When obtaining each value, the price range from the lowest value PBmin of the trade-in estimated price to the highest value PBmax is higher than the price range from the lowest value PAmin to the highest value PAmax of the estimated purchase price. You may add or subtract the offset price (> 0) to the total price of the parts, or you may multiply the total price of the parts by a factor greater than 1 or a coefficient less than 1, and any other Such a calculation formula may be used.
[0049]
Further, in the above-described embodiment, the maximum value PAmax of the estimated purchase price is compared with the threshold value P1, and when the PAmax exceeds P1, it is determined that it is in the purchaseable price range, but the minimum value PAmin of the estimated purchase price and the threshold value are determined. P1 ′ may be compared, and when PAmin exceeds P1 ′, it may be determined that it is in the purchaseable price range.
[0050]
Further, in the above-described embodiment, the minimum value PAmin and the maximum value PAmax of the estimated purchase price, and the minimum value PBmin and the maximum value PBmax of the estimated trade price are obtained, but the purchase estimated price and the estimated trade price have a range.
