Summary of the Invention

Problems to be Solved by the Invention

[0069] (Configuration - Transaction support device - Transaction support side control unit - Image information acquisition unit) The image information acquisition unit 32d is an image information acquisition means that acquires image information and specification information.

[0070] Here, "image information" refers to information showing images related to construction reuse materials. This image information is a concept that includes, for example, information showing two-dimensional images and / or three-dimensional images related to construction reuse materials, but in Embodiment 1, it will be described as information showing three-dimensional images related to construction reuse materials.

[0071] Furthermore, "specification information" refers to information indicating the specifications (specifically, performance and / or specifications) of the reused construction material. This specification information is a concept that includes, for example, information indicating the shape, dimensions, material, features, and / or intended use of the reused construction material, but in Embodiment 1, it will be described as text information indicating the dimensions of the reused construction material.

[0072] (Configuration - Transaction support device - Transaction support side control unit - Emissions information acquisition unit) The emissions information acquisition unit 32e is an emissions information acquisition means that acquires information (in Embodiment 1, this is text information; hereinafter referred to as "emissions information") indicating the amount of carbon dioxide emitted when construction reuse materials are collected.

[0073] (Configuration - Transaction support device - Transaction support side storage unit) The transaction support side storage unit 33 is a transaction support side storage means that records programs and various data necessary for the operation of the transaction support device 30, and as shown in Figure 4, it includes a first transaction method database (hereinafter, the database is referred to as "DB") 33a.

[0074] (Configuration - Transaction support device - Transaction support side storage unit - First transaction method DB) The first transaction method DB33a is a first transaction method information storage means that stores transaction method information used to identify transaction methods for construction reuse materials. As shown in Figure 5, it is configured by relating the item "deviation information" and the item "transaction method information" with the information corresponding to each item.

[0075] Of these, the information corresponding to the item "Discrepancy Information" is discrepancy information that is a requirement for specifying the trading method of construction reuse materials. For example, as shown in Figure 5, this includes the degree of discrepancy between supply timing and demand timing, such as "within 3 days".

[0076] Furthermore, the information corresponding to the item "Transaction Method Information" is transaction method information, and as shown in Figure 5, for example, it includes "First Direct Sale," which is a transaction method for reused construction materials.

[0077] (Transaction support processing) Next, we will describe the transaction support processing performed by the supply-side control unit 15 of the supply-side terminal device 10, the demand-side control unit 25 of the demand-side terminal device 20, and the transaction support-side control unit 32 of the transaction support device 30, which are configured as described above.

[0078] In the following explanation, the step will be abbreviated as "S" in the description of each process shown in Figures 6 to 8.

[0079] (Transaction Support Processing - Introduction) Transaction support processing is a process designed to support transactions involving reused construction materials.

[0080] The timing of executing this transaction support process is arbitrary, but in Embodiment 1, it will be described as being started after the power to the supply-side terminal device 10, the demand-side terminal device 20, and the transaction support device 30 is turned on.

[0081] In Embodiment 1, although the processing system 1 includes a plurality of supply-side terminal devices 10 and a plurality of demand-side terminal devices 20, the content of the transaction support processing performed by these supply-side terminal devices 10 and demand-side terminal devices 20 is all the same. Therefore, the following will describe the transaction support processing performed by the supply-side terminal device 10 (hereinafter referred to as the "target supply-side terminal device"), the demand-side terminal device 20 (hereinafter referred to as the "target demand-side terminal device"), and the transaction support device 30.

[0082] (Transaction support processing - Processing details) When the transaction support process is activated, as shown in Figure 6, the transaction support control unit 32 of the transaction support device 30 in SA1 determines whether or not the acquisition timing has arrived.

[0083] Here, "acquisition timing" refers to the timing at which misalignment information, image information, and specification information are acquired.

[0084] Furthermore, while the method for determining whether or not this acquisition timing has arrived is arbitrary, in Embodiment 1, the determination is made based on whether or not information indicating that construction reuse materials will be supplied (hereinafter referred to as "supply notification information") is received from the target supply-side terminal device via the transaction-dedicated website (or directly received from the target supply-side terminal device), and whether or not information indicating that a transaction for said construction reuse materials is requested (hereinafter referred to as "transaction request information") is received from the target demand-side terminal device via the transaction-dedicated website (or directly received from the target demand-side terminal device).

[0085] If the above supply notification information and / or transaction request information are received, it is determined that the acquisition timing has arrived. If the above supply notification information and / or transaction request information are not received, it is determined that the acquisition timing has not arrived.

[0086] Furthermore, the motivation for a consumer possessing a target demand-side terminal device to transmit transaction request information to the transaction support device 30 may include, for example, the consumer confirming that information regarding construction reuse materials supplied by a supplier possessing a target supply-side terminal device is posted on a dedicated transaction website (or on another website), or the consumer confirming with the supplier that the construction reuse materials are subject to transaction.

[0087] Then, the transaction support control unit 32 of the transaction support device 30 waits until it is determined that the acquisition timing has arrived (SA1, No), and when it is determined that the acquisition timing has arrived (SA1, Yes), it proceeds to SA2.

[0088] In SA2, the misalignment information acquisition unit 32a of the transaction support device 30 acquires misalignment information.

[0089] The method for obtaining this discrepancy information is arbitrary, but for example, it can be obtained as follows.

[0090] In other words, the information may be obtained by receiving discrepancies from a dedicated trading website, the target supply-side terminal device (specifically, the target supply-side terminal device owned by the supplier supplying the construction reuse materials subject to trading), or the target demand-side terminal device (specifically, the target supply-side terminal device owned by the demander who conducts a transaction between the supplier and the construction reuse materials).

[0091] Alternatively, the system may receive supply timing information indicating the supply timing from the target supply-side terminal device (or trading-dedicated website) via the trading-dedicated website, and also receive demand timing information indicating the demand timing from the target demand-side terminal device (or trading-dedicated website). Subsequently, the difference between the supply timing information and the demand timing information may be calculated, and the information indicating this calculated difference may be considered as deviation information, thereby deeming the deviation information to have been acquired.

[0092] When calculating the above difference, for example, if the supply timing (or demand timing) is earlier than the date and time of SA2 processing, the supply timing (or demand timing) may be replaced with the date and time of SA2 processing in the calculation.

[0093] In SA3, the image information acquisition unit 32d of the transaction support device 30 acquires image information and specification information.

[0094] The method for acquiring this image information and specification information is arbitrary, but in Embodiment 1, image information (specifically, information showing a 3D image of the construction reuse material) and specification information (specifically, information showing the dimensions of the construction reuse material) are acquired simultaneously via an imaging unit (not shown).

[0095] Specifically, in a structure, an imaging unit is installed near the construction reuse material (specifically, the construction reuse material related to the supply notification information (or transaction request information) received by SD1), and after imaging the construction reuse material with the imaging unit, image information and specification information are acquired from the imaging unit using a known method.

[0096] Here, the imaging unit corresponds to the "imaging means" in the claims, and is configured, for example, using a known image dimension measuring instrument, and is owned by the supplier or the manager of the transaction support device 30.

[0097] This acquisition method allows for easy acquisition of image and specification information, reducing the effort required for the acquisition process.

[0098] However, this is not limited to the above; for example, image information and specification information transmitted from the target supply terminal device, which are created by the supplier in a known manner, may also be obtained by receiving such information.

[0099] Alternatively, if the imaging unit only has the function of capturing three-dimensional (or two-dimensional) images of the construction reuse materials, the transaction support control unit 32 of the transaction support device 30 may use a known image analysis method (for example, an image analysis method using artificial intelligence, a similarity determination algorithm, or / or a measurement method of a predetermined standard) to automatically extract the dimensions of the construction reuse materials from the image information acquired from the imaging unit, and acquire the extracted information as "specification information." This reduces the effort required to create specification information.

[0100] In SA4, the emissions information acquisition unit 32e of the transaction support device 30 acquires emissions information.

[0101] The method for obtaining this emission information is optional, but in Embodiment 1, it is obtained by receiving emission information transmitted from the target supply-side terminal device, which is the amount of carbon dioxide emissions calculated by a method known to the supplier, and which indicates the amount of carbon dioxide emissions when construction reuse materials (specifically, construction reuse materials related to the above supply notification information (or above transaction request information)) are collected.

[0102] In SA5, the identification unit 32b of the transaction support device 30 identifies the transaction method for construction reuse materials (specifically, construction reuse materials related to the above supply notification information (or above transaction request information)) based on the deviation information acquired in SA2.

[0103] The method for identifying this transaction method is optional, but in Embodiment 1, it is identified as follows.

[0104] Specifically, first, from the discrepancy information stored in the first transaction method DB33a, the discrepancy information that matches the degree of discrepancy of the discrepancy information obtained by SA2 is identified. Then, from the transaction method information stored in the first transaction method DB33a, the transaction method information corresponding to the identified discrepancy information is extracted, and the transaction method of the extracted transaction method information is identified as the transaction method to be specified.

[0105] For example, if the discrepancy information obtained in SA2 is within 1 day, then discrepancies of 3 days or less may be identified from the discrepancies stored in the first transaction method DB33a, and then the transaction method information corresponding to the identified discrepancy information, the first direct trade, may be extracted to identify the transaction method to be identified, the first direct trade.

[0106] This identification method allows for the simple and rapid identification of trading methods for construction reuse materials, thereby improving the usability of the trading support device 30.

[0107] However, this is not limited to the above. For example, the deviation information acquired by SA2 may be transmitted to an appraisal device (not shown) held by an expert or technician who appraises trading methods, and then the expert may receive information indicating the trading method appraised based on the said deviation information, and the received information may be identified as the trading method to be specified.

[0108] In SA6, the provision unit 32c of the transaction support device 30 provides transaction method information indicating the transaction method identified in SA5.

[0109] The method of providing this transaction method information is optional, but in Embodiment 1, the transaction method information is provided by the transaction support communication unit 31 by transmitting it to the target supply-side terminal device and the target demand-side terminal device.

[0110] However, the method is not limited to this, and may also be provided by, for example, the transaction support communication unit 31 transmitting the transaction method information to only one of the target supply-side terminal device or the target demand-side terminal device. In this case, for example, the target supply-side terminal device may notify the target demand-side terminal device of the transaction method information via a dedicated transaction website, or transmit the transaction method information to the target demand-side terminal device.

[0111] In SA7, the provision unit 32c of the transaction support device 30 provides the image information and specification information acquired in SA3, and the emission information acquired in SA4. Subsequently, the transaction support control unit 32 of the transaction support device 30 moves to SA1, and thereafter repeats the processing from SA1 to SA7 in the same manner.

[0112] Here, the method of providing image information, specification information, and emission information is optional, but in Embodiment 1, the image information, etc., is provided by the transaction support side communication unit 31 by transmitting it to the target demand side terminal device at approximately the same timing as the processing of SA6 (or within a predetermined time after the processing of SA6).

[0113] This method of provision allows for the provision of image information, specification information, and emission information, enabling consumers to trade in construction reuse materials while considering the detailed composition of the materials and the carbon dioxide emissions generated during their collection.

[0114] However, the method is not limited to this; for example, the transaction support communication unit 31 may transmit image information, etc., to the target supply-side terminal device and the target demand-side terminal device. This makes it possible to output image information, etc., to the target supply-side terminal device.

[0115] Furthermore, as shown in Figure 7, in SB1, the supply-side control unit 15 of the target supply-side device determines whether or not the transaction method information provided (transmitted) by SA6 has been received by the supply-side communication unit 11.

[0116] The supply-side control unit 15 of the target supply-side device then waits until it is determined that the transaction method information has been received (SB1, No), and if it is determined that the transaction method information has been received (SB1, Yes), it proceeds to SB2.

[0117] In SB2, the supply-side output control unit 15a of the target supply-side device outputs the transaction method information received in SB1 to the supply-side output unit 13.

[0118] Here, the method for outputting the above transaction method information is arbitrary, but in Embodiment 1, a display area (hereinafter referred to as the "supply-side transaction display area") not shown is generated on the screen of the supply-side output unit 13 (specifically, the display), and the above transaction method information is output by displaying it in the generated supply-side transaction display area.

[0119] This output method allows suppliers to visually confirm transaction method information and understand the transaction method information.

[0120] However, this is not limited to the above. For example, in addition to displaying the above-mentioned transaction method information (or instead of displaying the above-mentioned transaction method information), the above-mentioned transaction method information may also be output as audio from the supply-side output unit 13 (specifically, the speaker).

[0121] In SB3, the supply-side control unit 15 of the target supply-side device determines whether or not the timing for ending the output of transaction method information in SB2 (hereinafter referred to as the "supply-side termination timing") has arrived.

[0122] The method for determining whether or not this supply-side termination timing has arrived is arbitrary, but in Embodiment 1, the determination is made based on whether or not a predetermined operation has been received via the supply-side operation unit 12, or whether or not a predetermined time (for example, 10 minutes) has elapsed since the processing of SB2 was completed.

[0123] If the above-mentioned predetermined operation is accepted, or if the above-mentioned predetermined time has elapsed, it is determined that the supply-side termination timing has arrived. If the above-mentioned predetermined operation is not accepted, or if the above-mentioned predetermined time has not elapsed, it is determined that the supply-side termination timing has not arrived.

[0124] Then, if the supply-side control unit 15 of the target supply-side device determines that the supply-side termination timing has not arrived (SB3, No), it repeats the processing of SB2 and SB3 until it determines that the supply-side termination timing has arrived. On the other hand, if it determines that the supply-side termination timing has arrived (SB3, Yes), it proceeds to SB1 and repeats the processing of SB1 to SB3 in the same manner thereafter.

[0125] Furthermore, as shown in Figure 8, in SC1, the demand-side control unit 25 of the target demand-side device determines whether or not the transaction method information provided (transmitted) in SA6, and the image information, specification information, and emission information provided in SA7 have been received by the demand-side communication unit 21.

[0126] Then, the demand-side control unit 25 of the target demand-side device waits until it is determined that the transaction method information, etc. has been received (SC1, No), and when it is determined that the transaction method information, etc. has been received (SC1, Yes), it proceeds to SC2.

[0127] In SC2, the demand-side output control unit 25a of the target demand-side equipment outputs the transaction method information, image information, specification information, and emission information received in SC1 to the demand-side output unit 23.

[0128] Here, the method for outputting the above-mentioned transaction method information, etc., is arbitrary, but in Embodiment 1, a display area (hereinafter referred to as the "demand-side transaction display area") not shown is generated on the screen of the demand-side output unit 23 (specifically, the display), and the transaction method information, image information, specification information, and emission information are output by displaying them in a list along the vertical or horizontal direction in the generated demand-side transaction display area.

[0129] This output method allows consumers to visually confirm transaction method information and understand the transaction methods.

[0130] However, this is not limited to the above. For example, in addition to displaying the above-mentioned transaction method information, etc. (or instead of displaying the above-mentioned transaction method information, etc.), the above-mentioned transaction method information, etc. (excluding image information) may also be output as audio through the demand-side output unit 23 (specifically, the speaker).

[0131] In SC3, the demand-side control unit 25 of the target demand-side device determines whether or not the timing for ending the output of transaction method information, etc., in SC2 (hereinafter referred to as the "demand-side termination timing") has arrived.

[0132] The method for determining whether or not this demand-side termination timing has arrived is arbitrary, but in Embodiment 1, the determination is made based on whether or not a predetermined operation has been received via the demand-side operation unit 22, or whether or not a predetermined time (for example, 10 minutes) has elapsed since the processing of SC2 was completed.

[0133] If the above-mentioned predetermined operation is accepted, or if the above-mentioned predetermined time has elapsed, it is determined that the demand-side termination timing has arrived. If the above-mentioned predetermined operation is not accepted, or if the above-mentioned predetermined time has not elapsed, it is determined that the demand-side termination timing has not arrived.

[0134] Then, if the demand-side control unit 25 of the target demand-side device determines that the demand-side termination timing has not yet arrived (SC3, No), it repeats the processing of SC2 and SC3 until it determines that the demand-side termination timing has arrived. On the other hand, if it determines that the demand-side termination timing has arrived (SC3, Yes), it proceeds to SC1 and repeats the processing of SC1 to SC3 in the same manner thereafter.

[0135] This transaction support processing enables the provision of transaction method information tailored to discrepancies, allowing suppliers and consumers to conduct transactions of reused construction materials using the transaction methods provided. Therefore, it becomes easier to conduct transactions of reused construction materials that meet the needs of both suppliers and consumers, thereby improving the tradability of reused construction materials.

[0136] (Effects of Embodiment 1) As described above, according to Embodiment 1, the system includes a misalignment information acquisition unit 32a that acquires misalignment information, a specification unit 32b that identifies a trading method for construction reuse materials based on the misalignment information acquired by the misalignment information acquisition unit 32a, and a provision unit 32c that provides trading method information indicating the trading method identified by the specification unit 32b. Therefore, trading method information corresponding to the misalignment information can be provided, and suppliers and consumers can conduct transactions of construction reuse materials using the trading method information. Thus, it becomes easier to conduct transactions of construction reuse materials that match the needs of suppliers and / or consumers, thereby improving the tradability of construction reuse materials.

[0137] Furthermore, since the providing unit 32c provides image information and specification information acquired by the image information acquisition unit 32d, it is possible to provide image information and specification information, for example, enabling suppliers and / or consumers to conduct transactions of construction reuse materials while taking into account the detailed composition of the construction reuse materials.

[0138] Furthermore, since the image information acquisition unit 32d acquires image information and specification information via an imaging unit that can acquire image information and specification information simultaneously, image information and specification information can be easily acquired, and the effort required for such acquisition can be reduced.

[0139] Furthermore, since the supply unit 32c provides emission information acquired by the emission information acquisition unit 32e, it is possible to provide emission information, for example, enabling suppliers and / or consumers to conduct transactions of construction reuse materials while taking into account the amount of carbon dioxide emitted when the construction reuse materials are collected.

[0140] [Embodiment 2] Next, the processing system according to Embodiment 2 will be described. Embodiment 1 is a form that identifies a trading method for construction reuse materials based on deviation information and value information described later. However, unless otherwise specified, the configuration of Embodiment 2 is substantially the same as that of Embodiment 1, and for configurations substantially the same as those of Embodiment 1, the same reference numerals or / ors and names used in Embodiment 1 will be used as necessary, and their explanation will be omitted.

[0141] (composition) First, the configuration of the processing system according to Embodiment 2 will be described. The processing system 1 according to Embodiment 2 is equipped with a supply-side terminal device 10, a demand-side terminal device 20, and a transaction support device 30, similar to the processing system 1 according to Embodiment 1.

[0142] (Configuration - Supply-side terminal equipment) First, let's describe the configuration of the supply-side terminal device 10.

[0143] The supply-side terminal device 10 according to Embodiment 2 is configured in substantially the same way as the supply-side terminal device 10 according to Embodiment 1.

[0144] (Configuration - Demand-side terminal equipment) Next, the configuration of the demand-side terminal device 20 will be described.

[0145] The demand-side terminal device 20 according to Embodiment 2 is configured in substantially the same way as the demand-side terminal device 20 according to Embodiment 1.

[0146] (Configuration - Transaction support device) Next, the configuration of the transaction support device 30 will be described.

[0147] As shown in Figure 9, the transaction support device 30 according to Embodiment 2 is configured in substantially the same way as the transaction support device 30 according to Embodiment 1. However, the details of the configuration of the transaction support control unit 32 and the transaction support storage unit 33 are improved as described below.

[0148] (Configuration - Transaction support device - Transaction support side control unit) As shown in Figure 9, the transaction support control unit 32 functionally comprises a deviation information acquisition unit 32a, a specification unit 32b, a provision unit 32c, an image information acquisition unit 32d, an emissions information acquisition unit 32e, and a value information acquisition unit 32f.

[0149] (Configuration - Transaction support device - Transaction support side control unit - Value information acquisition unit) Of these, the value information acquisition unit 32f is a value information acquisition means for acquiring value information.

[0150] Here, "value information" refers to information indicating the value of construction reuse materials. This value information is a concept that includes, for example, scarcity information, versatility information, and / or quality information, but in Embodiment 2, it will be described as including scarcity information, versatility information, and quality information.

[0151] Of these, "rarity information" refers to information indicating the degree of rarity of construction reuse materials. This rarity information is a concept that includes, for example, information indicating the degree of rarity based on a historical perspective and / or an artistic perspective of construction reuse materials. However, in Embodiment 2, it is explained as information indicating the degree of rarity based on a historical perspective of construction reuse materials (specifically, text information indicating a three-level rarity, such as "high," "average," and "low," based on a predetermined standard regarding a historical perspective (for example, a standard that takes into account construction reuse materials from a predetermined era)). However, it is not limited to this, and may also be text information indicating a two-level or four-level or higher rarity.

[0152] Furthermore, "versatility information" refers to information indicating the degree of versatility of construction reuse materials. This versatility information is a concept that includes, for example, information indicating the degree of versatility based on the usability and / or installation aspects of construction reuse materials. In Embodiment 2, however, it is described as information indicating the degree of versatility based on the usability aspects of construction reuse materials (specifically, text information indicating a three-level degree of versatility, such as "high," "average," and "low," based on predetermined criteria related to the usability aspects (for example, criteria that take into account the usability of a given construction reuse material)). However, it is not limited to this, and may also be text information indicating a two-level or four-level or higher degree of versatility.

[0153] Furthermore, "quality information" refers to information indicating the degree of quality of the reused construction material. This quality information is a concept that includes, for example, information indicating the degree of quality based on the manufacturing and / or utilization aspects of the reused construction material. In Embodiment 2, however, it is described as information indicating the degree of quality based on the manufacturing aspects of the reused construction material (specifically, text information indicating three levels of quality, such as "high," "average," and "low," based on predetermined standards related to the manufacturing aspects (e.g., known manufacturing standards, etc.)). However, it is not limited to this, and may also be text information indicating two or four or more levels of quality.

[0154] As described later, this type of value information makes it possible to identify trading methods for reused construction materials based on scarcity information, versatility information, and / or quality information, making it easier to trade reused construction materials that meet the needs of suppliers and / or consumers.

[0155] (Configuration - Transaction support device - Transaction support side storage unit) As shown in Figure 9, the transaction support storage unit 33 includes a first transaction method DB33a and a second transaction method DB33b.

[0156] (Configuration - Transaction support device - Transaction support side storage unit - Second transaction method DB) Of these, the second transaction method DB33b is different from the first transaction method DB33a and is a second transaction method information storage means that stores transaction method information used to identify transaction methods for construction reuse materials. As shown in Figure 10, this second transaction method DB33b is configured by relating the item "value information" and the item "transaction method information" with the information corresponding to each item. Furthermore, the item "value information" includes the items "rarity information", "versatility information", and "quality information" as items related to value information.

[0157] Here, the information corresponding to the item "Value Information" is the value information that is required to identify the trading method for reused construction materials.

[0158] Of these, the information corresponding to the item "Scarcity Information" is scarcity information, for example, as shown in Figure 10, which refers to the degree of scarcity of the reused construction material (specifically, scarcity based on a historical perspective), such as "high." The information corresponding to the item "Versatility Information" is versatility information, for example, as shown in Figure 10, which refers to the degree of versatility of the reused construction material (specifically, the degree of versatility based on a usability perspective), such as "high, average, or low." The information corresponding to the item "Quality Information" is quality information, for example, as shown in Figure 10, which refers to the degree of quality of the reused construction material (specifically, the degree of quality based on a manufacturing perspective), such as "high, average, or low."

[0159] Furthermore, the information corresponding to the item "Transaction Method Information" is transaction method information, and as shown in Figure 10, this includes "First Direct Sale," which is a transaction method for reused construction materials.

[0160] (Transaction support processing) Next, we will describe the transaction support processing performed by the supply-side control unit 15 of the supply-side terminal device 10, the demand-side control unit 25 of the demand-side terminal device 20, and the transaction support-side control unit 32 of the transaction support device 30, which are configured as described above.

[0161] (Transaction Support Processing - Introduction) First, SD1 to SD4, SD7, and SD8 in Figure 11 in the transaction support processing according to Embodiment 2, which is executed by the transaction support control unit 32, are the same as SA1 to SA4, SA6, and SA7 in Figure 6 in the transaction support processing according to Embodiment 1, which is executed by the transaction support control unit 32, so their explanation will be omitted.

[0162] Furthermore, the transaction support processing according to Embodiment 2, which is executed by the supply-side control unit 15, is the same as the transaction support processing shown in Figure 7 according to Embodiment 1, which is executed by the supply-side control unit 15, so its explanation will be omitted.

[0163] Furthermore, the transaction support processing according to Embodiment 2, which is executed by the demand-side control unit 25, is the same as the transaction support processing shown in Figure 8 according to Embodiment 1, which is executed by the demand-side control unit 25, so its explanation will be omitted.

[0164] (Transaction support processing - Processing details) Furthermore, as shown in Figure 11, in SD5, the value information acquisition unit 32f of the transaction support device 30 acquires value information (specifically, scarcity information, versatility information, and quality information).

[0165] The method for obtaining this value information is optional, but for example, it may be obtained in the following way.

[0166] In other words, it may be obtained by receiving value information transmitted from the target supply terminal device, which indicates the value of construction reuse materials (specifically, construction reuse materials related to supply notification information (or transaction request information) received at SD1) that have been appraised by the supplier using a method known to the supplier.

[0167] Alternatively, the image information and specification information acquired by SD3 may be transmitted to the appraisal device, and then value information generated based on the image information and specification information by an expert or other person may be received from the appraisal device.

[0168] In SD6, the identification unit 32b of the transaction support device 30 identifies a transaction method for construction reuse materials (specifically, construction reuse materials related to the above-mentioned supply notification information (or above-mentioned transaction request information)) based on the deviation information acquired in SD2 and the value information acquired in SD5.

[0169] The method for identifying this transaction method is optional, but in Embodiment 2, the transaction method is identified by prioritizing the transaction method information extracted from the second transaction method DB33b over the transaction method information extracted from the first transaction method DB33a.

[0170] Specifically, first, the system identifies discrepancy information from the discrepancy information stored in the first transaction method DB33a that matches the degree of discrepancy of the discrepancy information obtained by SD2. Then, it extracts the transaction method information corresponding to the identified discrepancy information from the transaction method information stored in the first transaction method DB33a.

[0171] Next, it is determined whether there is any value information in the value information stored in the second transaction method DB33b that matches the value of the value information obtained in SD5.

[0172] If the above value information exists, the transaction method information corresponding to the value information determined to exist is extracted from the transaction method information stored in the second transaction method DB33b, and the extracted transaction method information is identified as the transaction method to be specified. On the other hand, if the above value information does not exist, the transaction method information extracted from the first transaction method DB33a is identified as the transaction method to be specified.

[0173] For example, if the discrepancy information obtained in SD2 is within 1 day, and the scarcity information obtained in SD5 is low, the generality information is high, and the quality information is high, then discrepancy information within 3 days is identified from the discrepancy information stored in the first transaction method DB33a, and then the transaction method information corresponding to the identified discrepancy information, the first direct sale, is extracted. Also, if it is determined that there is value information in the value information stored in the second transaction method DB33b that matches the value of the value information obtained in SD5, then the transaction method information corresponding to the value information determined to exist, the indirect sale, is extracted from the transaction method information stored in the second transaction method DB33b. Then, based on the transaction method information extracted from the second transaction method DB33b, the transaction method to be identified, the indirect sale, may be identified.

[0174] As another example, if the discrepancy information obtained in SD2 is within 1 day, and the scarcity information obtained in SD5 is average, the generality information is low, and the quality information is low, then discrepancy information within 3 days is identified from the discrepancy information stored in the first transaction method DB33a, and then the transaction method information corresponding to the identified discrepancy information, the first direct sale, is extracted. Also, if it is determined that there is no value information in the value information stored in the second transaction method DB33b that matches the value of the value information obtained in SD5, then transaction method information may not be extracted from the second transaction method DB33b, and the transaction method to be identified, the first direct sale, may be identified based on the above transaction method information extracted from the first transaction method DB33a.

[0175] This SD6 processing makes it possible to identify trading methods for reused construction materials based on deviation and value information, making it easier to trade reused construction materials that meet the needs of suppliers and / or consumers.

[0176] (Effects of Embodiment 2) Thus, according to Embodiment 2, the identification unit 32b identifies a method for trading construction reuse materials based on the misalignment information acquired by the misalignment information acquisition unit 32a and the value information acquired by the value information acquisition unit 32f. This makes it possible to identify a method for trading construction reuse materials based on the misalignment information and value information, and makes it easier to conduct transactions of construction reuse materials that meet the needs of suppliers and / or consumers.

[0177] Furthermore, since the value information includes scarcity information indicating the degree of scarcity of the reused construction material, versatility information indicating the degree of versatility of the reused construction material, and / or quality information indicating the degree of quality of the reused construction material, it becomes possible to identify trading methods for reused construction material based on scarcity information, versatility information, and / or quality information, making it even easier to trade reused construction material that meets the needs of suppliers and / or consumers.

[0180] (Regarding decentralization and integration) Furthermore, the electrical components described above are functional concepts and do not necessarily need to be physically configured as shown in the diagram. In other words, the specific forms of distribution and integration of each part are not limited to those shown in the diagram, and all or part of them can be functionally or physically distributed or integrated in any unit according to various loads and usage conditions. For example, the trading support device 30 may be distributed among multiple devices configured to communicate with each other, with the trading support control unit 32 provided in some of these multiple devices and the trading support storage unit 33 provided in other parts of these multiple devices.

[0181] (Regarding shape, numerical values, structure, and time series) With regard to the components illustrated in the embodiments and drawings, their shapes, numerical values, or the interrelationships of the structure or time series of multiple components can be arbitrarily modified and improved within the scope of the technical concept of the present invention.

[0182] (Regarding structures) In the embodiments 1 and 2 described above, the structure was explained as a building structure under demolition, such as an office building being demolished. However, it is not limited to this, and may be a building structure that is not being demolished, for example.

[0183] (Regarding supply-side terminal equipment and demand-side terminal equipment) In the embodiments 1 and 2 described above, the supply-side terminal device 10 and the demand-side terminal device 20 are each composed of smartphones, but the invention is not limited to these, and may be composed of, for example, a tablet device, a stationary personal computer, or a laptop computer.

[0184] (Regarding trading support equipment) In embodiments 1 and 2 described above, the transaction support device 30 is described as being composed of a cloud server, but it is not limited to this, and may be composed of, for example, a server device installed in a management facility.

[0185] Furthermore, although the above embodiments 1 and 2 described the transaction support device 30 as comprising an image information acquisition unit 32d and an emissions information acquisition unit 32e, it is not limited to this configuration, and for example, the image information acquisition unit 32d and / or the emissions information acquisition unit 32e may be omitted.

[0186] In this case, for example, in the transaction support processing according to Embodiment 1, the processing of SA3, SA4, or / and SA7 may be omitted. Also, in the transaction support processing according to Embodiment 2, the processing of SD3, SD4, or / and SD8 may be omitted.

[0187] (Regarding the second transaction method database) In the above embodiment 2, it was explained that the second transaction method DB33b stores scarcity information, generality information, and quality information. However, it is not limited to this, and for example, it may store only one or two of the scarcity information, generality information, or quality information.

[0188] (Regarding transaction support processing) In Embodiment 1 described above, it was explained that in the processing of SA7, image information and specification information acquired in SA3, and emission information acquired in SA4 are provided, but this is not limited to this. For example, depending on the transaction status of the construction reuse materials, only one or two of the image information, specification information, or emission information may be provided (the same applies to the transaction support processing according to Embodiment 2).

[0189] Furthermore, in the above embodiment 2, it was explained that in the processing of SD8, image information and specification information acquired in SD3, and emission information acquired in SD4 are provided, but this is not limited to this. For example, in addition to this image information, specification information, and emission information, value information acquired in SD5 may also be provided to the demand-side terminal device 20 and / or the supply-side terminal device 10. This makes it easier for suppliers and / or demanders to understand the details of the construction reuse materials by providing value information.

[0190] Furthermore, in the above embodiment 2, it was explained that in the processing of SD6, the transaction method information extracted from the second transaction method DB 33b is given priority over the transaction method information extracted from the first transaction method DB 33a in identifying the transaction method, but this is not limited to this. For example, as shown in Figure 12, the transaction support device 30 may have a third transaction method DB that stores, in place of the first transaction method DB 33a and the second transaction method DB 33b, discrepancy information and value information (specifically, rarity information, versatility information, and quality information) used to identify the transaction method of construction reuse materials, and transaction method information in an interrelated manner. The identification unit 32b of the transaction support device 30 may then extract transaction method information from the transaction method information stored in the third transaction method DB that matches the discrepancy information obtained in SD2 and the value information obtained in SD5, and identify the extracted transaction method information as the transaction method to be identified.
