Description

Transaction support device, transaction support method and transaction support program

The present invention relates to a transaction support device, a transaction support method, and a transaction support program.

There is a market that sells used equipment that can be used for its original purpose, rather than as scrap. For example, home electric appliances such as washing machines and refrigerators are frequently traded as second-hand goods at physical stores and virtual stores on networks. The transaction price in the market varies greatly depending on how the home appliance was used in the past.

The support service system of Patent Document 1 calculates an assessed price when a recycle shop (an intermediary for buying and selling second-hand home appliances) purchases (purchases) second-hand home appliances from general users. The system multiplies the selling price of a new product by a predetermined coefficient determined from the manufacturer's brand, date of manufacture, deterioration state, etc., to calculate an appraisal price.

JP-A-2003-36390

The support/service system of Patent Literature 1 determines the state of deterioration of home electric appliances based on the rough usage conditions and appearance that users perceive on a daily basis. Therefore, the calculated appraisal price does not reflect objective and technical data obtained from the home appliance. As a result, the appraisal price is not persuasive to both the "selling user" who sells the home appliance and the "buying user" who will purchase the home appliance in the future.
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to calculate a persuasive appraisal price of a used device.

A transaction support device of the invention comprises an input processing unit that acquires operation information of the home electric appliance from a second-hand home appliance, an assessment unit that calculates an index for the price of the electric home appliance based on the acquired operation information, and and an output processing unit that displays an assessed price of the home appliance calculated based on the calculated index.
Other means are described in the detailed description.

According to the present invention, it is possible to calculate a persuasive appraisal price for used equipment.

(Transaction of second-hand electrical appliances)
FIG. 1 is a diagram for explaining the outline of the transaction flow of second-hand electrical appliances. Before describing the present invention, a general existing example of a transaction flow will be described. There are users (old users) 72 who own and sell home appliances to be traded at the time of the transaction and users (new users) 71 who buy the home appliances as subjects of transactions. Store 74 provides a place of transaction. Assessor 73 presents an assessed price for the transaction. The assessment support platform 75 exchanges data necessary for transactions with the buying user 71 , the selling user 72 and the assessor 73 . The assessment company 76 is an organization to which the assessor 73 belongs. The assessment support company 77 is an organization that operates an assessment support platform.

- The selling user 72 presents the home appliance to the assessor 73 and requests an assessment (arrow 81a).
The assessor 73 registers himself or herself as an assessor with the assessment support platform 75, and inquires about the information (new price, etc.) of the presented home appliance (arrow 81b).
- The selling user 72 provides the assessment support platform 75 with information about himself and information about the home appliance (deterioration in appearance, etc.) (arrow 81c).
The assessment support platform 75 interviews the user 72 to sell about the usage status of the home appliance and recommends the timing of the sale (arrow 81d).
- The assessment support platform 75 notifies the assessor 73 of the assessed price (arrow 81e).
- Assessor 73 reports the assessed price to selling user 72 and pays the price (arrow 81f).

- The assessor 73 delivers the home appliance with the assessed price to the store 74 (arrow 81g).
- Assessor 73 reports the assessed price and completion of delivery to assessment company 76 (arrow 81h).
The appraisal support platform 75 presents the appraisal price of the electrical appliance that the buying user 71 wishes to purchase to the buying user 71 (arrow 81i).
- The store 74 presents the appraisal price to the buying user 71 and then sells the home appliance (arrow 81j).
- The buying user 71 pays the price to the shop 74 (arrow 81k).
The user 71 who buys registers the electric home appliance with the assessment support platform 75 and provides information on the electric home appliance (deterioration in appearance, etc.) (arrow 81m).

- The assessment company 76 reports the sales of home electric appliances to the assessment support company 77, and pays the fee for using the assessment support platform 75 (arrow 81n).
- The assessment support company 77 operates the assessment support platform 75 (arrow 81p).
- The assessment company 76 transmits information necessary for cooperation, such as point-of-sale information, to the assessment support platform 75 (arrow 81q).
- The store 74 reports the sale of the home appliance to the appraisal company 76 (arrow 81r).
- The assessment company 76 pays the operating expenses of the store to the store 74 (arrow 81s).

The transaction flow is not limited to what is described here. For example, the selling user 72, rather than the assessor 73, may deliver to the store 74 via a carrier. In this case, the selling user 72 or the store 74 reports the delivery of the target home appliance to the assessor 73 , and the assessor 73 reports the content and assessed price to the assessment company 76 .

Also, the assessor 73 may be an employee of the store 74. In this case, the flow (arrow 81g) of delivering the product to the shop 74 with the assessed price attached is omitted. By having the assessor 73 be an employee of the store 74, the assessment company 76 can unify the assessment price and delivery completion report (arrow 81h) and home appliance sales report (arrow 81r).

Furthermore, the assessment company 76 may be an organization to which the assessor 73 belongs and an organization that owns the store 74 . In this case as well, it is assumed that the assessor 73 will be in a position to assess the home appliance as an employee of the store 74, so the assessment company 76 will report the assessment price and delivery completion (arrow 81h) and the sale of the home appliance. Reports (arrow 81r) can be unified.

The present invention particularly relates to the scene of determining the appraisal price of a transaction between a selling user (old user) 72 and a buying user (new user) 71 in FIG. This scene includes a case where a user buys a certain home appliance and sells another home appliance at the same time. In this case, the user is both the buying user 71 and the selling user 72 . At this time, the home appliances to be sold may be home appliances that were purchased second-hand in the past. In this way, repeated resource recycling of home appliances among users is accelerated, leading to further activation of a resource recycling society.

Hereinafter, a form for carrying out the present invention (referred to as "this embodiment") will be described in detail with reference to the drawings. This embodiment is an example in which a broker calculates an assessed price of a home appliance. An intermediary may be a "dealer" who is a party to a transaction on its own account, or a "broker" who provides a place for transactions between others, or neither of these, but merely an appraisal. It may be a person who calculates the price. The intermediary, which will be described later, is a concept that combines the assessor 73, the store 74, the assessment support platform 75, the assessment company 76, and the assessment support company 77 in FIG. The appraisal price in this embodiment is based on the theoretical price obtained by deducting the deterioration due to use from the selling price when the product is new, and the market price is added to the theoretical price.

Auxiliary storage device 15 may be configured independently from transaction support device 1 .

A user terminal device 3 and a device 4 exist in a living room 2 . The device 4 is a home appliance such as an air conditioner, a heating cooker, a washing machine, or a refrigerator. The device 4 has one or more sensors 41 , and the sensor 41 measures arbitrary physical quantities around the device 4 itself and the device 4 . The device 4 stores the measured time-series physical quantity as an operation history 42 . If the type of equipment is different, the type of physical quantity to be measured is also different (details will be described later). The user terminal device 3 is a portable or stationary computer operated by the user of the equipment 4 .

The transaction support device 1 is connected to the user terminal device 3, equipment 4, product management device 5, maintenance management device 6, and external transaction device 7 via a wired or wireless network 8. That is, each of the user terminal device 3, the device 4, the product management device 5, the maintenance management device 6, and the external transaction device 7 has a communication device (not shown). The product management device 5 is operated by the manufacturer of the equipment 4 . The product management device 5 stores device information 31 about the devices 4 manufactured by the company.

The maintenance management device 6 is operated by the maintenance company of the equipment 4 . The maintenance management device 6 stores equipment maintenance information 34 about the equipment 4 maintained by the company. The external transaction device 7 is operated by a broker other than the operator of the transaction support device 1 . The external transaction device 7 stores external transaction information 35 about the equipment 4 traded in its own market.

The transaction support device 1 acquires the device information 31, the device maintenance information 34, and the external transaction information 35 from the product management device 5, the maintenance management device 6, and the external transaction device 7, respectively, and stores them in its own auxiliary storage device 15. (details below). Further, the transaction support device 1 acquires the operation history 42 from the device 4 and stores it as device operation information 32 and device operation information 33 in its own auxiliary storage device 15 .
As is clear from the above, "second-hand home appliances" are those home appliances that can communicate with the transaction support device 1 that have been used by at least one user after being shipped from the factory. 42, and although it is "used", it has sufficiently new functions.

The operating conditions in the operating condition column 124 are arbitrary operating modes of the device 4 detected by the sensor 41 of the device 4 (operating constraints or instructions set for the device 4 by the user). Operating conditions differ depending on the type of equipment. For example, the operating condition of the washing machine is "fashionable washing mode" or "drying mode", the operating information of the heating cooker is "continuous heating mode" or "intermittent heating mode", and the operating information of the refrigerator is , "quick freezing mode" or "normal freezing mode" (see the thick line frame). When the user of device 4 selects one of these pairs, a "o" is stored in that column. The number of operating conditions (number of dimensions) included in one pair may be other than "2" in FIG.

(Equipment maintenance information)
FIG. 6 is an example of the equipment maintenance information 34. As shown in FIG. In the device maintenance information 34, the device type is stored in the device type column 132, the time is stored in the time column 133, and the maintenance information is stored in the maintenance information column 134, in association with the device ID stored in the device ID column 131. ing.

The transaction time in the transaction time column 147 is the date when the device was traded.
In the example of FIG. 7, four cases of transactions of "Washing machine A123-45 model of Company A" are accumulated on "Website O".

For the external transaction price, in addition to the superiority and rarity of the device 4 to be traded, fluctuations in the supply and demand of the device may be considered. For example, when the old user sells many of the devices 4 owned by the old user and the new user buys them (for example, when the new user moves), the external transaction price is adjusted to be smaller than when it is not. good too.

(assessment information)
FIG. 8 is an example of assessment information 36 . In the assessment information 36, in association with the device ID stored in the device ID column 151, the device type column 152 indicates the device type, the reference price column 153 indicates the reference price, the depreciation index column 154 indicates the depreciation index, The assessed price is stored in the assessed price column 155 .

The device IDs in the device ID column 151 are the same as the device IDs in FIG.
The device types in the device type column 152 are the same as the device types in FIG.
The reference price in the reference price column 153 is the selling price of the device 4 (column 107 in FIG. 3). The standard price is called the "standard price" because it serves as the standard (starting point) for calculating the appraisal price.

The depreciation index in the depreciation index column 154 is a coefficient by which the reference price is multiplied. There are six types of depreciation indicators, namely operating depreciation indicators, environmental depreciation indicators, operating depreciation indicators, maintenance depreciation indicators, market depreciation indicators and overall depreciation indicators. The product of the operational depreciation index, the environmental depreciation index, the operational depreciation index, the maintenance depreciation index, and the market depreciation index is the total depreciation index. In other words, each of the operational depreciation index, the environmental depreciation index, the operational depreciation index, the maintenance depreciation index, and the market depreciation index is a factor of the total depreciation index. Table 156 in FIG. 8 shows this relationship (details will be described later).
The assessed price in the assessed price column 155 is the result of multiplying the reference price by the comprehensive depreciation index.

(Depreciation index calculation function (reference number 38 in FIG. 2 and table 156 in FIG. 8))
Now, to simplify the explanation, we will focus on the depreciation index of washing machines (inside the thick line frame). The operating depreciation index calculation function _F1 is a function that outputs an operating depreciation index when the inner tub rotation speed and inner tub vibration frequency are input. The operating depreciation index is normalized to a range of 0 to 1 inclusive. A "1" indicates that the device 4 is like new, and a "0" indicates that the device 4 is degraded to the point that it cannot be traded and must be discarded. More generally, an operating depreciation index ranging from “0” to “1” is associated with each of a large number of regions (clusters) in a multidimensional space centered on the average value of operating information in FIG. It is The transaction support device 1 determines the position and size of the cluster and the operating depreciation index associated therewith statistically or based on the manufacturer's specifications.

The environmental depreciation index calculation function _F2 is a function that outputs an environmental depreciation index when the temperature, humidity, and installation location are input. The environmental depreciation index is normalized to a range of 0 to 1 inclusive. A "1" indicates that the device 4 is like new, and a "0" indicates that the device 4 is degraded to the point that it cannot be traded and must be discarded. More generally, "0" to "1" for each of a large number of regions (clusters) in a multidimensional space centered on the average value of the environment information (column 115) in FIG. 4 and the installation location A range of environmental depreciation indicators are associated. The transaction support device 1 determines the position and size of the cluster and the environmental depreciation index associated therewith statistically or based on the manufacturer's specifications.

The operation depreciation index calculation function _F3 is a function that outputs an operation depreciation index when the fashion wash mode time and the drying mode time are input. The operating depreciation index is normalized to a range of 0 to 1 inclusive. A "1" indicates that the device 4 is like new, and a "0" indicates that the device 4 is degraded to the point that it cannot be traded and must be discarded. More generally, "0" to "1" for each of a large number of regions (clusters) in a multidimensional space with the axis of the accumulated time during which the equipment 4 is operated under the operating conditions (column 124) in FIG. ” range of operating depreciation indicators. The transaction support device 1 determines the position and size of the cluster and the operating depreciation index associated therewith statistically or based on the manufacturer's specifications.

The maintenance depreciation index calculation function _F4 is a function that outputs a maintenance depreciation index when the number of times the inner tank is disassembled and cleaned and the number of times the filter is replaced are input. The maintenance depreciation index is normalized to a range of 0 to 1 inclusive. A "1" indicates that the device 4 is like new, and a "0" indicates that the device 4 is degraded to the point that it cannot be traded and must be discarded. More generally, a maintenance depreciation index ranging from “0” to “1” for each of a large number of regions (clusters) in a multidimensional space centered on the number of maintenance information (column 134) in FIG. is associated with. The transaction support device 1 determines the position and size of the cluster and the maintenance depreciation index associated therewith statistically or based on the specifications prepared by the maintenance company.

The market depreciation index calculation function _F5 is a function that outputs a market depreciation index when an external transaction price is input. The maintenance depreciation index is normalized to a range between 0 and no upper limit. "0" indicates that the device 4 has deteriorated to the point that it cannot be traded and must be discarded. More generally, there is a market depreciation index in the range of “0” or more for each of a large number of intervals (clusters) on the number line centered on the average value of external transaction prices (column 146) in FIG. Associated. The transaction support device 1 statistically determines the position and size of the cluster and the market depreciation index associated therewith.

When at least one of the depreciation indices F ₁ to F ₅ is "0", the total depreciation index F is "0" regardless of the magnitude of the other indices. In this case, the device 4 must be discarded based on the provisions of the Home Appliance Recycling Law. However, instead of uniformly discarding all the parts provided in the device 4, some of the parts may be reused. For example, a part determined to be reusable may be reused in a new product, or an individual part may be resold to the manufacturer of the device 4 . For example, a recycling factory that discards and dismantles home appliances based on the Home Appliance Recycling Law may determine whether or not to allow reuse.

(Regarding base price and depreciation)
In the above description, the selling price as a new product was used as the reference price. However, this is only an example, and another predetermined price as a second-hand item may be used as the reference price. The operation depreciation index, the environmental depreciation index, the operation depreciation index, and the maintenance depreciation index are “depreciated” in the range of 0 to 1, on the premise that the equipment 4 deteriorates. However, this is only an example, and each of these indices may exceed "1" depending on conditions.

(referred to as a “buy transaction”).

The selling information in the selling information column 165 is information on selling transactions.
The recycling ticket number of the sale information is the number described in the "home appliance recycling ticket", and uniquely identifies the device 4 to be discarded. As is generally known, those who intend to dispose of air conditioners, televisions, refrigerators, and washing machines among home appliances purchase a "Home Appliance Recycling Ticket" and attach the stub to the air conditioner, etc. must be brought to a designated collection point. Of course, the broker may pick up the air conditioner or the like and bring it to a designated pick-up location. In this embodiment, the transaction support device 1 recommends the old user to purchase a home appliance recycling ticket when "0" is calculated as the total depreciation index.

Using the recycling ticket number as a search key, the transaction support device 1 can acquire the tracking information 169 that chronologically indicates the recycling companies that accept the discarded equipment 4 . Transaction support device 1 accesses an external server (not shown) operated by an organization of recycling companies or the like, acquires tracking information 169 , and stores it in auxiliary storage device 15 .

The desired price of the sell information is the price desired by the old user in the sell transaction.
The assessed price of the sale information is the same as the assessed price in FIG.
The transaction price of the selling information is a price obtained by subtracting the intermediary's profit (buying margin) from the appraisal price in FIG.
The old user whose record stores the recycle ticket number has given up on giving up the device 4 for a fee, and both the appraisal price and the transaction price are "0".

The buy information in the buy information column 166 is information in the buy transaction.
The desired price of the buy information is the price desired by the new user in the buy transaction.
The appraisal price of the buying information is the same as the appraisal price in FIG.
The transaction price of the buy information is a price obtained by adding the intermediary's profit (selling margin) to the appraisal price in FIG. Either the buy margin or the sell margin may be "0".

The incentive in the incentive column 167 is an economic value (electronic money, electronic coupon, etc.) given to the old user or new user. The incentive value is defined in advance according to the content of the transaction and the degree of contribution of the former user to the reduction of the environmental load (details will be described later).
The cumulative incentive in the cumulative incentive column 168 is a value obtained by accumulating incentive values for each user.

(Incentive value)
The incentive value given to the old user is determined, for example, as follows.
・The higher the appraisal amount, the higher the incentive value.
・The smaller the difference obtained by subtracting the appraisal price from the standard price, the larger the incentive value.
・The higher the overall depreciation index, the higher the incentive value.
- The greater the predetermined index among the depreciation indexes _F1 to _F5 , the greater the incentive value.
- The greater the number of times the old user has closed sell transactions in the past, the greater the incentive value.
・The greater the difference obtained by subtracting the appraisal price from the desired price, the greater the incentive value. However, an upper limit is set for the desired price.
・When a recycling ticket number is presented, the greater the number of presentations, the greater the contribution to environmental load reduction, and the greater the incentive value.

The incentive value given to the new user is determined, for example, as follows.
・The greater the number of times a new user has completed buy transactions in the past, the greater the value of the incentive.
・The greater the difference obtained by subtracting the desired price from the appraisal price, the greater the incentive value. However, a lower limit is set for the desired price.

In addition, the buying user 71 (FIG. 1) can also repeatedly use the transaction support device 1 in the next transaction in order to resell the device 4 purchased from the selling user 72 (FIG. 1). The position of the user 72 who changes his position in the next transaction, and the person who is in the position of the user 72 who sells can make a persuasive transaction with the person who is in the position of the user 71 who buys. Furthermore, incentives are given to both the person who is in the position of the selling user 72 and the person who is in the position of the buying user 71 . In other words, both the environmental value side of promoting resource circulation among users and the economic value side of promoting persuasive transactions between users are compatible.

(Processing procedure)
10 and 11 are flowcharts of processing procedures. FIG. 11 is a continuation of FIG. 12 and 13 will be referred to as appropriate during the description of the flowchart. Now, a certain user "U01" is about to sell a used washing machine for a fee. User U01 corresponds to selling user 72 in FIG.

At step S201, the input processing unit 21 of the transaction support device 1 accepts an assessment request. Specifically, the input processing unit 21 receives an assessment request from the user terminal device 3 operated by the user U01.

In step S202, the input processing unit 21 displays the assessment request screen 51 (FIG. 12). Specifically, the input processing unit 21 displays the assessment request screen 51 on the user terminal device 3 . Although it is in the middle of the flow chart, the explanation will temporarily move to FIG.

FIG. 12 is an example of an assessment request screen 51. The user U01 enters the device type, manufacturer name, model, and purchase time in the device type column 52, manufacturer name column 53, model column 54, and purchase time column 55, respectively. The user U01 takes an image of a label (not shown) attached to the device 4 by the manufacturer at the time of shipment, and inputs (pasters) the image into the device label image field 56 . In addition to various information such as the manufacturer's name, model, and manufacturing date, the device ID is recorded on the label. The user U01 takes images of the front, side, and top surfaces of the device 4, and inputs (pasters) those images (used images in the column 116 in FIG. 4) into the front column 57a, the side column 57b, and the top column 57c, respectively. . The user U01 inputs the location information (URL etc.) of the operation history 42 of the device 4 into the operation history location column 58. FIG. The user U01 inputs the desired price (column 165 in FIG. 9) in the desired price column 59 for the sell transaction.

The user U01 may register the equipment 4 in the transaction support device 1 when purchasing a new product for the purpose of knowing the appraisal price of the equipment 4 on a daily basis, obtaining support for daily control of the equipment 4, and the like. In this case, the transaction support device 1 acquires data other than the used images 57a, 57b and 57c and the desired price 59 at the time of registration. When requesting an assessment, the user U01 inputs only the used images 57a, 57b and 57c and the desired price 59 to the assessment request screen 51. FIG. The description returns to FIG.

In step S203, the input processing unit 21 receives the device type and the like. Specifically, the input processing unit 21 receives information input to the assessment request screen 51 by the user U21. The input processing unit 21, if the imaging time of the use image input to the assessment request screen 51 is not new enough to satisfy a predetermined standard (for example, if it goes back one month or more from the current time), the input processing unit 21 sends the use image to the user. Prompt to take an image again.

In step S<b>204 , the input processing unit 21 acquires the device information 31 . Specifically, firstly, the input processing unit 21 transmits to the product management device 5 the combination of the device type, manufacturer name and model input on the assessment request screen 51 or the image of the label. For convenience of explanation, it is assumed here that an image of a label (recording device ID "M01") is transmitted. Then, the product management device 5 acquires the record of the device M01 from the device information 31 of itself and transmits it to the transaction support device 1 .
Second, the input processing unit 21 stores the received record in the auxiliary storage device 15 as the device information 31 .

In step S205, the input processing unit 21 acquires the device operation information 32. Specifically, the input processing unit 21 acquires time-series operation information, environment information, and installation location for a predetermined period from the operation history 42 of the device M01, and stores the acquired information as a record of the device operation information 32. , and stored in the auxiliary storage device 15 . The predetermined period is desirably the period from the sale date of the device M01 to the present time (the same applies hereinafter). The input processing unit 21 stores the used image in the used image column 116 of the record at the time of imaging.

In step S206, the input processing unit 21 acquires the device operation information 33. Specifically, the input processing unit 21 acquires time-series operating conditions for a predetermined period from the operation history 42 of the device M01, and stores the acquired operating conditions in the auxiliary storage device 15 as a record of the device operating information 33. do.

In step S<b>207 , the input processing unit 21 acquires the equipment maintenance information 34 . Specifically, first, the input processing unit 21 transmits the device ID “M01” to the maintenance management device 6 . Then, the maintenance management device 6 acquires the record of the device M01 from the device maintenance information 34 of itself and transmits it to the transaction support device 1 .
Second, the input processing unit 21 stores the received record in the auxiliary storage device 15 as the equipment maintenance information 34 .

In step S<b>208 , the input processing section 21 acquires the external transaction information 35 . Specifically, first, the input processing unit 21 transmits to the external transaction device 7 the combination of the device type, manufacturer name, and model input to the assessment request screen 51 . Then, the product management device 5 acquires a record having the combination from its own external transaction information 35 and transmits it to the transaction support device 1 .
Second, the input processing unit 21 stores the received record in the auxiliary storage device 15 as the external transaction information 35 .

At step S209, the assessment unit 22 of the transaction support device 1 acquires a reference price. Specifically, the assessment unit 22 sets the sales price (column 107 in FIG. 3) of the device information 31 acquired in step S204 as the reference price (column 153 in FIG. 8).

In step S210, the assessment unit 22 calculates an operating depreciation index. Specifically, the assessment unit 22 calculates the operating depreciation index using the operating information (column 114) for the device M01 and the operating depreciation index calculation function _F1 in the device operating information 32 acquired in step S205. do. For example, the larger the representative value of the inner tub rotation speed and the larger the representative value of the inner tub vibration frequency in a predetermined period, the closer the operating depreciation index is to “0”. The representative value here includes an average value, minimum value, maximum value, median value, integrated value, accumulated value, etc. (the same shall apply hereinafter).

In step S211, the assessment unit 22 calculates an environmental depreciation index. Specifically, the assessment unit 22 calculates the environmental depreciation index using the environmental information (column 115) of the device M01 and the environmental depreciation index calculation function _F2 in the device operation information 32 acquired in step S205. do. For example, the larger the representative value of the difference between the temperature and its reference value in a predetermined period, the larger the representative value of the difference between the humidity and its reference value, the longer the time it was installed outdoors or on the dirt floor, the more the environmental depreciation. The index approaches "0".

In step S212, the assessment unit 22 calculates a driving depreciation index. Specifically, the assessment unit 22 calculates the operating depreciation index using the operating condition (column 124) for the device M01 and the operating depreciation index calculation function _F3 in the device operating information 33 acquired in step S206. do. For example, the shorter the time spent in the stylish washing mode and the longer the time spent in the drying mode in a predetermined period, the closer the operating depreciation index is to "0."

In step S213, the assessment unit 22 calculates a maintenance depreciation index. Specifically, the assessment unit 22 calculates the maintenance depreciation index using the maintenance information (column 134) for the device M01 in the device maintenance information 34 acquired in step S207 and the maintenance depreciation index calculation function _F4 . do. For example, the smaller the number of times the inner tank is disassembled for cleaning and the smaller the number of times the filter is replaced in a predetermined period, the closer the maintenance depreciation index is to "0".

In step S214, the assessment unit 22 calculates a market depreciation index. Specifically, the assessing unit 22 determines the external transaction price (column 146) and market depreciation for a device having the same combination of device type, manufacturer name, and model as the device M01, among the external transaction information 35 acquired in step S208. The index calculation function _F5 is used to calculate the operating depreciation index. For example, the smaller the representative value of external transaction prices in a predetermined period, the closer the market depreciation index is to “0”.

In step S215, the assessment unit 22 calculates a comprehensive depreciation index. Specifically, the assessment unit 22 multiplies the depreciation indices F ₁ to F ₅ calculated in steps S210 to S214 to calculate a total depreciation index. Note that the assessment unit 22 may calculate the total depreciation index based on the following formula. The assessment unit 22 proposes to discard the device M01 when the total depreciation index becomes "0".

Comprehensive depreciation index = ( _W1 x _F1 ) x ( _W2 x _F2 ) x ( _W3 x _F3 ) x ( _W4 x _F4 ) x ( _W5 x _F5 )
_W1 x _W2 x _W3 x _W4 x _W5 = 1
0< _W1 , _W2 , _W3 , _W4 , _W5
Here, W1, W2, . . . are weights by which each depreciation index is multiplied.

In step S216, the assessment unit 22 compares the images of the devices. Specifically, the assessment unit 22 compares the used image of the device 4 input to the assessment request screen 51 with the new image of the device information 31 acquired in step S204 to determine the degree of appearance deterioration of the device 4. Calculate The assessment unit 22 detects a change in the color of the device 4 from the new image (degree of dirt), the number of scratches or dents on the surface of the device 4, etc., and sets the detection result to, for example, "100%". It is converted to the degree of appearance deterioration as a correction coefficient.

In step S217, the assessment unit 22 corrects the comprehensive depreciation index. Specifically, the assessment unit multiplies the overall depreciation index calculated in step S215 by the degree of appearance deterioration, and obtains the post-correction overall depreciation index.

At step S218, the assessment unit 22 calculates an assessment price. Specifically, the assessment unit 22 multiplies the reference price acquired in step S209 by the corrected total depreciation index to obtain an assessment price.

In step S219, the assessment unit 22 creates assessment information 36 (Fig. 8). Specifically, the assessment unit 22 creates a record of the assessment information 36 for the device M01 using each depreciation index and assessment price calculated in steps S210 to S215 and S218.

In step S220, the assessment unit 22 creates transaction information 37 (Fig. 9). Specifically, the assessment unit 22 creates a record of the transaction information 37 for the device M01. At this stage, the transaction price and recycle number in the buy information column 166, incentive column 167, cumulative incentive column 168, and sell information column 165 of the record are blank. When the comprehensive depreciation index becomes "0", the appraisal price and transaction price in the selling information column 165 become "0".

In step S221, the output processing unit 23 of the transaction support device 1 displays the assessment result screen 61 (Fig. 13). Specifically, the output processing unit 23 displays the assessment result screen 61 on the user terminal device 3 . Although it is in the middle of the flow chart, the explanation will temporarily move to FIG.

FIG. 13 is an example of the assessment result screen 61. The output processing unit 23 displays the device type, manufacturer name, and model input to the assessment request screen 51 in the device type column 62, the manufacturer name column 63, and the model column 64, respectively. The output processing unit 23 displays the reference price, each depreciation index, and appraisal price in the table 65, and also displays a comment 67 (within a thick line frame) for each depreciation index. The auxiliary storage device 15 stores comment information (not shown) in which comments 67 are stored in association with each value of each depreciation index or each cluster described above. 67 is obtained.

The comment 67 is valuable information for new users who are considering buying the device M01. The assessment unit 22 asks the old user (selling user 72 in FIG. 1) whether or not the comment 67 can be disclosed to the new user (buying user 71 in FIG. 1). It accepts pressing any of the "No" buttons 66b. When the "yes" button 66a is pressed, the output processing unit 23 stores the comment 67 in the auxiliary storage device 15 in association with the device ID. The output processing unit 23 displays the comment 67 associated with the device to the new user who is considering buying the device. The description returns to FIG.

In step S222, the assessment unit 22 gives an incentive. Specifically, the assessment unit 22 determines the incentive based on the example described above when the establishment of the sale transaction is confirmed, and stores the incentive and cumulative incentive in the record created in step S220. After that, the procedure ends.

When the selling user submits the home appliance to an assessment transaction, the assessment unit 22 collects not only the operating information generated by the selling user using the home appliance, but also the operating information generated by one or more other users in the past. The operation information used and generated can also be taken into account in the assessment. The input processing unit 21 acquires operation information attributed to the selling user who intends to submit for assessment transaction, and stores it in the auxiliary storage device 15 as part of the device operation information 32 (first operation information). At the same time, the input processing unit 21 acquires operation information attributed to past users as second operation information, and stores it in the auxiliary storage device 15 . The assessment unit 22 reflects the first operation information and the second operation information in the average value of the operation information, etc., and for each of a large number of regions (clusters) in the multidimensional space around the average value, Associate a working depreciation index ranging from "0" to "1". By doing this, it becomes possible to calculate the index more accurately based on not only the most recent operation information but also the past operation information.
