[0009] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In each drawing, the same or corresponding elements are designated by the same reference numerals, and for clarity of explanation, duplicate explanations will be omitted as necessary. In addition, for ease of understanding, the scale of each part in the drawings may differ from the actual scale.

[0010] Embodiment 1 First, referring to Figure 1, an example configuration of a timber matching system 100 according to the first embodiment will be described. The timber matching system 100 includes a confirmation unit 110, a selection unit 120, a calculation unit 130, and a display unit 140. The timber matching system 100 is an information processing system that presents timber that meets a user's desired conditions. The user is a person who wishes to purchase timber. The user may be, for example, a person who uses furniture made from timber, or a person who makes furniture from timber.

[0011] The timber matching system 100 is communicatively connected to a timber database 200 via a network 300. The network 300 connects information and communication devices via wired or wireless communication lines. The network 300 may be a network accessible only to some information devices, or a network such as the Internet that is available to an unspecified number of people. The timber database 200 is a storage device in which timber information for multiple timbers is registered. The timber information is information about timber, and includes, for example, at least one of standing tree position, tree species, tree height, diameter at breast height, and forest age. The standing tree position is three-dimensional location information of the location where the timber is growing, and may be, for example, three-dimensional coordinate data acquired by airborne LiDAR (Light Detection and Ranging). The diameter at breast height is the diameter of the timber trunk at a position 1.2 m above the ground. The timber information is linked to each of the multiple timbers and stored in the timber database 200.

[0012] The timber matching system 100 is an information processing system that uses timber information stored in the timber database 200 to identify and present timber that meets a user's desired purchasing conditions. The confirmation unit 110 confirms the user's desired purchasing conditions. The desired purchasing conditions are information about the timber the user wishes to purchase, and include, for example, at least one of the following: type of furniture, delivery date, price, origin, forest age, and tree species. Here, the type of furniture refers to the type of furniture the user wishes to purchase, and is the type of furniture that will be produced using the timber. The user may input the desired purchasing conditions using, for example, a user terminal (not shown). The user terminal is an information processing terminal communicatively connected to the timber matching system 100. The desired purchasing conditions input by the user are transmitted to the timber matching system 100, and the confirmation unit 110 accepts the desired purchasing conditions and confirms their contents.

[0013] The selection unit 120 selects lumber that meets the desired purchase conditions confirmed by the confirmation unit 110, by referring to the lumber database 200. For example, if the desired purchase conditions are "table, within one month," the selection unit 120 selects lumber that is of a tree species suitable for making a table and that can be delivered within one month, by referring to the lumber database 200. The selection unit 120 usually selects multiple lumber that meet the desired purchase conditions.

[0014] The calculation unit 130 calculates the amount of CO2 fixation for each piece of wood selected by the selection unit 120. The amount of CO2 fixation is the amount of CO2 fixed by wood, and is calculated, for example, by the following formula 1. Note that a is the market survival rate. V is the volume of wood fixed in furniture. A is the volume density of the wood species used. B is the carbon (C) content of the wood species used. C is the conversion coefficient from C to CO2. Amount of CO2 fixed = a(V×A×B×C)...Formula 1

[0015] The calculation unit 130 may further calculate a transportation cost for each piece of timber selected by the selection unit 120. The transportation cost is the cost required to transport the timber. The calculation unit 130 first uses the tree position information to draw a circular line centered on the timber on a map and detects multiple nearby forest roads. The calculation unit 130 then calculates the distance and elevation difference between the junction with the forest road and the position of the standing tree where the timber is growing, using topographical data. The topographical data may be data calculated using airborne LiDAR acquired in advance. Next, the calculation unit 130 calculates the slope angle from the forest road to the position of the standing tree using the following equation 2. Slope angle = (elevation of timber - elevation of forest road) / distance from timber to forest road... Equation 2

[0016] The calculation unit 130 performs this process for each node and determines the extraction route by extracting the node where the product of the inclination angle and the distance from the forest road is the smallest. At this time, the calculation unit 130 excludes nodes where the inclination angle is 70° or more. Next, the calculation unit 130 calculates the timber extraction cost using the following equation 3. Note that b to e are coefficients. x1 is the distance from the forest road to the timber. x2 is the inclination angle from the forest road to the timber. x3 is the volume of the timber. x4 is the height of the timber. Carry-out cost = bx1 + cx2 + d(x3 + x4) + e··· Equation 3

[0017] The display unit 140 displays the wood pieces selected by the selection unit 120 to the user in descending order of CO2 fixation amount. Specifically, the display unit 140 generates a wood piece list in which the multiple wood pieces selected by the selection unit 120 are sorted in descending order of the CO2 fixation amount calculated by the calculation unit 130, and transmits the wood piece list to the user terminal. The user then checks the wood piece list transmitted to the user terminal. Furthermore, if the calculation unit 130 calculates the transportation cost, the display unit 140 may generate a wood piece list for the wood pieces selected by the selection unit 120 in descending order of CO2 fixation amount and transportation cost. In this way, the wood piece matching system 100 can present wood pieces that meet the user's desired purchasing conditions to the user in descending order of CO2 fixation amount. This is expected to encourage the user to consider wood pieces with a high CO2 fixation amount as wood pieces to purchase. In other words, the wood piece matching system 100 can perform wood piece matching that takes into account the CO2 fixation amount.

[0018] Next, an example of the timber matching method according to the first embodiment will be described with reference to FIG. 2. When the user's desired purchase conditions are input, the confirmation unit 110 confirms the input desired purchase conditions (step S101). Next, the selection unit 120 refers to the timber database 200 and selects timber that meets the desired purchase conditions confirmed in step S101 (step S102). It is assumed that timber information has been stored in the timber database 200 prior to step S102. Next, the calculation unit 130 calculates the amount of CO2 fixation for the timber selected in step S102 (step S103). Next, the display unit 140 displays the timbers selected in step S102 to the user in descending order of the amount of CO2 fixation calculated in step S103 (step S104). In this way, the timber matching method according to the first embodiment can perform timber matching that takes into account the amount of CO2 fixation.

[0019] Embodiment 2 After performing timber matching, the user may order the matched timber. Embodiment 2 is an embodiment illustrating an example of a timber matching system that allows a user to order and receive timber. FIG. 3 is a block diagram showing an example configuration of a timber matching system 400 according to embodiment 2. As shown in FIG. 3, the timber matching system 400 includes an instruction unit 450 in addition to the configuration shown in FIG. 1. The instruction unit 450 transmits work requests to each of the contractors who will perform work such as felling, cutting, processing, and transporting the timber.

[0020] 4 is a flowchart illustrating a timber matching method according to the second embodiment. When a user inputs desired purchase conditions into a user terminal, the user terminal transmits the desired purchase conditions to the timber matching system 400. The confirmation unit 110 confirms the received desired purchase conditions (step S201). Next, the selection unit 120 selects timber from the timber database 200 that meets the desired purchase conditions confirmed in step S201 (step S202). Next, the calculation unit 130 calculates the amount of CO2 fixation for the timber selected in step S202 (step S203). Next, the display unit 140 generates a list of timbers in which the timbers selected in step S202 are arranged in descending order of the amount of CO2 fixation calculated in step S203, and transmits the list to the user terminal to present it to the user (step S204).

[0021] The user checks the timber list sent to the user terminal and considers purchasing timber. If the user wishes to purchase timber, the user inputs a purchase request for the timber they wish to purchase on the user terminal. If the user wishes to process the timber, the user also inputs a processing request when inputting the purchase request. In other words, in this case, the purchase request includes a processing request. The user terminal transmits a purchase request for the timber they wish to purchase to the timber matching system 400. Upon receiving the purchase request (Yes in step S205), the instruction unit 450 transmits a felling request for the timber they wish to purchase to the felling worker terminal (not shown) (step S206). The felling worker confirms the received felling request, determines a felling date, and inputs it into the felling worker terminal. The felling worker fells the timber on the felling date. The felling worker terminal transmits the input felling date to the timber matching system 400. The timber matching system 400 receives the felling date from the felling worker terminal (step S207).

[0022] Next, the instruction unit 450 transmits the transportation request for the felling date received in step S207 to the transportation worker terminal (not shown) (step S208). The transportation worker checks the transportation request received by the transportation worker terminal, transports the timber on the felling date, and delivers the timber to the user. If the purchase request includes a processing request (step S209 Yes), the instruction unit 450 transmits a processing request to the processing worker terminal (not shown) to request processing of the timber (step S210). The processing worker checks the processing request received by the processing worker terminal and processes the timber. In this case, the transportation worker delivers the timber to the user after processing. In this way, the timber matching system 400 can not only match timber, but also transmit instructions to each worker from purchasing timber to handing it over to the user.
