[0001] The present disclosure relates to a management device and a management method.

Background Art

[0002] With the increasing awareness of environmental problems, there has been a growing interest in the CO2 emissions generated by the production of products distributed in the market. Upstream companies (upstream companies) in the supply chain may be required by downstream companies (downstream companies) that receive the products to disclose the CO2 emissions generated for the production of the products. The upstream company calculates the CO2 emissions generated for the production of the products and discloses this to the downstream company.

[0003] For example, Japanese Unexamined Patent Application Publication No. 2016-126372 (Patent Document 1) discloses a method for calculating the CO2 emissions in the transportation process of products (including materials and parts). The method for calculating the CO2 emissions in the transportation process disclosed in Japanese Unexamined Patent Application Publication No. 2016-126372 calculates the CO2 emissions corresponding to the purchase amount of the article from a predetermined coefficient table, the industry to which the company belongs, and the purchase amount of the article.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In calculating the CO2 emissions discharged for producing a product, it is desirable to take into account not only the CO2 emissions in the production process but also the CO2 emissions in the transportation process. For example, in a moving body such as a railway or a transport vehicle that transports products, a plurality of products (parts, raw materials) with different delivery destinations may be loaded together. In such a case, it is desired to establish a method for accurately calculating the CO2 emissions in the transportation process of each delivered product.

[0006] The present disclosure has been made to solve the above problems, and an object of the present disclosure is to accurately calculate the CO2 emissions in the transportation process of each product when a plurality of products are loaded together in a moving body that transports products.

Means for Solving the Problems

[0007] (1) A management device according to an aspect of the present disclosure is a management device that manages a moving body that transports a plurality of products loaded together. The plurality of products includes a first product and a second product. The management device includes a storage device that stores the amount of energy consumed by the moving body in a transportation section, and a control device that calculates the CO2 emissions of the first product due to transportation and the CO2 emissions of the second product due to transportation based on the amount of energy and the weight ratio between the first product and the second product loaded on the moving body.

[0008] According to the above configuration, the control device calculates the CO2 emissions of the first product due to transportation and the CO2 emissions of the second product due to transportation based on the amount of energy consumed in the transportation of the transportation section where the products are loaded together and the weight ratio of the loaded products. By using the weight ratio of the loaded products, the CO2 emissions of the first product due to transportation and the CO2 emissions of the second product due to transportation can be appropriately calculated.

[0009] (2) In a certain embodiment, the control device apportions the amount of energy to the first product and the second product based on the weight ratio, and calculates the CO2 emissions of the first product due to transportation and the CO2 emissions of the second product due to transportation.

[0010] According to the above configuration, the control device apportions the amount of energy consumed during the transportation of the transportation section in which products are mixed according to the weight ratio of the mixed products. By apportioning the amount of energy based on the weight ratio, the CO2 emissions of the first product due to transportation and the CO2 emissions of the second product due to transportation can be appropriately calculated.

[0011] (3) In a certain embodiment, the transportation section includes a first section in which the first product and the second product are mixed, and a second section in which the first product is loaded and the second product is not loaded. The control device apportions the amount of energy consumed by the moving body in the first section to the first product and the second product based on the weight ratio of the first product and the second product, and apportions the amount of energy consumed by the moving body in the second section to the first product.

[0012] According to the above configuration, the control device apportions the amount of energy consumed in each section according to the weight ratio of the mixed products for each section. In the first section, since the first product and the second product are mixed, the control device apportions (allocates) the amount of energy consumed by the moving body in the first section to the first product and the second product based on the weight ratio. On the other hand, in the second section, since the second product is not loaded, the control device apportions (allocates) the amount of energy consumed by the moving body in the second section to the first product. In this way, by apportioning the amount of energy consumed in each section divided based on the presence or absence of mixed loading of products, the CO2 emissions of the first product due to transportation and the CO2 emissions of the second product due to transportation can be appropriately calculated.

[0013] (4) In a certain embodiment, the storage device stores conversion information for converting the amount of energy into CO2 emissions. The control device uses the conversion information to convert the amount of energy apportioned to the first product into the CO2 emissions of the first product due to transportation, and converts the amount of energy apportioned to the second product into the CO2 emissions of the second product due to transportation.

[0014] According to the above configuration, the power consumption can be appropriately converted into the CO2 emission amount.

[0015] (5) The management method according to another aspect of the present disclosure is a management method for managing a moving body that transports a plurality of products in a mixed manner. The plurality of products include a first product and a second product. The management method includes a step of reading out the amount of energy consumed by the moving body in the transportation section, and a step of calculating the CO2 emission amount of the first product due to transportation and the CO2 emission amount of the second product due to transportation based on the amount of energy and the weight ratio between the first product and the second product loaded on the moving body.

Advantages of the Invention

[0016] According to the present disclosure, when a plurality of products are loaded on a moving body that transports products, the CO2 emission amount in the transportation process of each product can be accurately calculated.

[0018] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and their description will not be repeated.

[0019] [Embodiment 1] FIG. 1 is an overall configuration diagram of a management system 100 according to Embodiment 1. FIG. 2 is a hardware configuration diagram of the management system 100 according to Embodiment 1.

[0021] In Embodiment 1, at least Company A and Company C form a supply chain. Company A is an upstream company of Company C in the supply chain. Company A produces product 15 at factory 1. Product 15 is an electronic component. Note that product 15 is not limited to being an electronic component and may be various raw materials. The product 15 produced at factory 1 is, for example, grouped into a predetermined delivery unit to form a product set 16. The product set 16 is delivered to factory 3 of Company C via, for example, a plurality of transportation means.

[0022] Also, in Embodiment 1, at least Company B and Company D form a supply chain. Company B is an upstream company of Company D in the supply chain. Company B produces product 25 at factory 2. Product 25 is an electronic component. Note that product 25 is not limited to being an electronic component and may be various raw materials. The product 25 produced at factory 2 is, for example, grouped into a predetermined delivery unit to form a product set 26. The product set 26 is delivered to factory 4 of Company D via, for example, a plurality of transportation means.

[0023] Server 10 of Company A stores the CO2 emission amount Qp1 per unit quantity of Product 15. The CO2 emission amount Qp1 includes the CO2 emission amount required to produce Product 15 using raw materials in Company A's production line and the CO2 emission amount emitted during the production of the above raw materials. The CO2 emission amount emitted during the production of raw materials can be obtained from upstream enterprises (not shown) in the supply chain. Furthermore, Server 10 calculates the CO2 emission amount Qp1set per product set 16 using the CO2 emission amount Qp1 and stores this. Hereinafter, the CO2 emission amount Qp1set is also referred to as the "CO2 emission amount Qp1set in the production process".

[0024] In response to a request from Server 30 of Company C, or triggered by the delivery of product set 16 to Company C, Server 10 transmits the CO2 emission amount Qp1set in the production process to Server 30.

[0025] Server 20 of Company B stores the CO2 emission amount Qp2 per unit quantity of Product 25. The CO2 emission amount Qp2 includes the CO2 emission amount required to produce Product 25 using raw materials in Company B's production line and the CO2 emission amount emitted during the production of the above raw materials. The CO2 emission amount emitted during the production of raw materials can be obtained from upstream enterprises (not shown) in the supply chain. Furthermore, Server 20 calculates the CO2 emission amount Qp2set per product set 26 using the CO2 emission amount Qp2 and stores this. Hereinafter, the CO2 emission amount Qp2set is also referred to as the "CO2 emission amount Qp2set in the production process".

[0026] In response to a request from Server 40 of Company D, or triggered by the delivery of product set 26 to Company D, Server 20 transmits the CO2 emission amount Qp2set in the production process to Server 40.

[0027] The management center 50 manages the transport vehicles 9A to 9D and the transport railway 5. For example, the enterprise operating the management center 50 receives requests for transporting products from enterprise A and enterprise B. In this embodiment, an example where the management center 50 manages both the transport vehicles 9A to 9D and the transport railway 5 will be described. However, it is also possible that the management entity for managing the transport vehicles 9A to 9D is different from the management entity for managing the transport railway 5. In such a case, a management center for managing the transport vehicles 9A to 9D and a management center for managing the transport railway 5 are provided. Hereinafter, when not particularly distinguishing each of the transport vehicles 9A to 9D, they may be collectively referred to as "transport vehicle 9".

[0028] First, the product set 16 is loaded onto the transport vehicle 9A from the factory 1 of enterprise A and transported to station A 6. At station A 6, the product set 16 is loaded onto the transport railway 5 and transported to station B 7. Then, at station B 7, the product set 16 is loaded onto the transport vehicle 9C and transported to the factory 3 of enterprise C. First, the product set 26 is loaded onto the transport vehicle 9B from the factory 2 of enterprise B and transported to station A 6. At station A 6, the product set 26 is loaded onto the transport railway 5 and transported to station B 7. Then, at station B 7, the product set 26 is loaded onto the transport vehicle 9D and transported to the factory 4 of enterprise D. Here, the product set 16 and the product set 26 are mixedly loaded on the transport railway 5 and transported from station A 6 to station B 7.

[0029] The transport vehicle 9 is a vehicle equipped with an internal combustion engine (not shown). Also, although not shown in any of the transport vehicles 9, they are equipped with a communication device and a GPS (Global Positioning System) receiver. The communication device may be, for example, a DCM (Data Communication Module). The transport vehicle 9 is configured to be communicable with the management center 50 via the communication device. The transport vehicle 9 is configured to transmit position information and fuel consumption information to the management center 50 at a predetermined cycle. The fuel consumption information indicates the amount of fuel consumed by the transport vehicle 9 during a predetermined cycle. The fuel consumption information may be information on the remaining amount of fuel.

[0030] The transportation railway 5 is driven using electricity or fuel. The transportation railway 5 may be a train or a locomotive. In Embodiment 1, the transportation railway 5 is a train driven using electricity. Although not shown in any figure, the transportation railway 5 includes a power conversion device, a motor, and a communication device. The transportation railway 5 is configured to transmit information on power consumption (energy consumption) to the management center 50 at a predetermined cycle.

[0031] The management center 50 includes a control device 51, a storage device 52, and a communication device 53. The control device 51, the storage device 52, and the communication device 53 are connected to a bus 54. Note that the management center 50 corresponds to an example of the "management device" according to the present disclosure.

[0032] The control device 51 is constituted by, for example, an integrated circuit including a CPU (Central Processing Unit). The control device 51 includes a memory and executes various programs stored in the memory. The various programs include an operating system and the like. The memory includes, for example, a ROM (Read Only Memory) storing the various programs described above, and a RAM (Random Access Memory) that functions as a working memory and temporarily stores various data necessary for the execution of the various programs.

[0033] The memory device 52 stores a first conversion formula (first conversion information) for converting the power consumption into the CO2 emission amount, and a second conversion formula (second conversion information) for converting the fuel consumption into the CO2 emission amount. The first conversion formula may, for example, multiply the power consumption by a first CO2 emission coefficient. The first CO2 emission coefficient may be, for example, a value published by a country, a government, an operator, or the like. The first CO2 emission coefficient may be set for each type of power (such as whether it is renewable energy or not). The second conversion formula may, for example, multiply the fuel consumption by a second CO2 emission coefficient. The second CO2 emission coefficient may be, for example, a value published by a country, a government, an operator, or the like. The second CO2 emission coefficient may be set for each type of fuel (such as gasoline, light oil, biodiesel, etc.). The first conversion formula and the second conversion formula are updated by the control device 51, for example, as the published first CO2 emission coefficient and the published second CO2 emission coefficient are updated.

[0034] The communication device 53 is configured to be communicable with each of the servers 10 to 40. The communication between the communication device 53 and each of the servers 10 to 40 is performed via, for example, the Internet or the like. Also, the communication device 53 is configured to be communicable with the transport railway 5 and the transport vehicle 9. The communication between the communication device 53 and the transport railway 5 and the transport vehicle 9 is performed via, for example, the Internet or the like.

[0035] The control device 51 calculates the CO2 emission amount in the transport process, and reports the calculated CO2 emission amount to the enterprises at the transport destination (Enterprise C and Enterprise D in Embodiment 1).

[0036] In Embodiment 1, the management center 50 receives a transport request for the product set 16 from the server 10 of Enterprise A. The server 10 notifies the management center 50 of the delivery number and weight information of the product set 16. Also, the management center 50 receives a transport request for the product set 26 from the server 20 of Enterprise B. The server 20 notifies the management center 50 of the delivery number and weight information of the product set 26.

[0037] Transport vehicles 9A and 9B receive product sets 16 and 26 at factory 1 of Company A and factory 2 of Company B, respectively. Transport vehicle 9A transports product set 16 from factory 1 of Company A to Station A6. Transport vehicle 9B transports product set 26 from factory 2 of Company B to Station A6. Product sets 16 and 26 are loaded together on transport railway 5 and transported from Station A6 to Station B7. Thereafter, at Station B7, product set 16 is loaded onto transport vehicle 9C and delivered to factory 3 of Company C. At Station B7, product set 26 is loaded onto transport vehicle 9D and delivered to factory 4 of Company D.

[0038] In addition, in Embodiment 1, it is assumed that only product set 16 is loaded on transport vehicles 9A and 9C. Also, it is assumed that only product set 26 is loaded on transport vehicles 9B and 9D. Further, it is assumed that only product sets 16 and 26 are loaded on transport railway 5.

[0039] The control device 51 calculates the CO2 emission amount Qa emitted during transportation based on the fuel consumption amount Fa consumed by transport vehicle 9A for transporting product set 16 from factory 1 of Company A to Station A6. The control device 51 inputs the fuel consumption amount Fa into the second conversion formula to calculate the CO2 emission amount Qa. Also, the control device 51 calculates the CO2 emission amount Qm1 emitted by the transportation of product set 16 by transport railway 5 from Station A6 to Station B7 by the method described later. Furthermore, the control device 51 calculates the CO2 emission amount Qc emitted during transportation based on the fuel consumption amount Fc consumed by transport vehicle 9C for transporting product set 16 from Station B7 to factory 3 of Company C.

[0040] The control device 51 adds the CO2 emission amount Qa, the CO2 emission amount Qm1, and the CO2 emission amount Qc according to the following formula (1) to calculate the CO2 emission amount Qt1set in the transportation process of product set 16.

[0041] Qt1set = Qa + Qm1 + Qc ··· (1) The control device 51 reports the calculated CO2 emission amount Qt1set in the transportation process to the server 30 of Company C via the communication device 53.

[0042] The server 30 of Company C adds the CO2 emission amount Qp1set in the production process reported by Company A and the CO2 emission amount Qt1set in the transportation process reported by the management center 50 to calculate the CO2 emission amount Q1set of the delivered product set 16. For example, the server 30 can calculate the CO2 emission amount Q1 of the product 15 by dividing the CO2 emission amount Q1set by the number of products 15 included in the product set 16. The server 30 of Company C stores the CO2 emission amount Q1set and the CO2 emission amount Q1.

[0043] The control device 51 calculates the CO2 emission amount Qb emitted by transportation based on the fuel consumption amount Fb consumed by the transport vehicle 9B for transporting the product set 26 from Factory 2 of Company B to Station A6. The control device 51 inputs the fuel consumption amount Fb into the second conversion formula to calculate the CO2 emission amount Qb. Also, the control device 51 calculates the CO2 emission amount Qm2 emitted by transporting the product set 26 by the transport railway 5 from Station A6 to Station B7 by the method described later. Furthermore, the control device 51 calculates the CO2 emission amount Qd emitted by transportation based on the fuel consumption amount Fd consumed by the transport vehicle 9D for transporting the product set 26 from Station B7 to Factory 4 of Company D.

[0044] The control device 51 calculates the CO2 emission amount Qt2set in the transportation process of the product set 26 by adding the CO2 emission amount Qb, the CO2 emission amount Qm2, and the CO2 emission amount Qd according to the following formula (2).

[0045] Qt2set = Qb + Qm2 + Qd ··· (2) The control device 51 reports the calculated CO2 emission amount Qt2set in the transportation process to the server 40 of Company D via the communication device 53.

[0046] The server 40 of Company D adds the CO2 emission amount Qp2set in the production process reported by Company B and the CO2 emission amount Qt2set in the transportation process reported by the management center 50 to calculate the CO2 emission amount Q2set of the delivered product set 26. For example, the server 40 can calculate the CO2 emission amount Q2 of the product 25 by dividing the CO2 emission amount Q2set by the number of products 25 included in the product set 26. The server 40 of Company D stores the CO2 emission amount Q2set and the CO2 emission amount Q2.

[0047] Figure 3 is a functional block diagram of a control device 51 showing a function for calculating the CO2 emission amount discharged by the transportation by the transportation railway 5. The control device 51 includes a power consumption acquisition unit 511, an information acquisition unit 512, a pressing unit 513, a CO2 emission amount calculation unit 514, and a storage unit 515. The control device 51 functions as the power consumption acquisition unit 511, the information acquisition unit 512, the pressing unit 513, the CO2 emission amount calculation unit 514, and the storage unit 515 by executing a program stored in the memory. Note that the power consumption acquisition unit 511, the information acquisition unit 512, the pressing unit 513, the CO2 emission amount calculation unit 514, and the storage unit 515 can also be realized by, for example, dedicated hardware (electric circuit).

[0048] The power consumption acquisition unit 511 acquires information on the power consumption from the transportation railway 5 via the communication device 53. The power consumption acquisition unit 511 integrates the power consumption acquired until the transportation railway 5 moves from Station A 6 to Station B 7. The power consumption acquisition unit 511 stores the integrated power consumption Etotal in the storage device 52. Note that the power consumption acquisition unit 511 may be configured to output the power consumption Etotal to the pressing unit 513.

[0049] The information acquisition unit 512 acquires the delivery number and the information of the weight Mc of the product set 16 from the server 10 of Company A. The information acquisition unit 512 stores the information of the delivery number and the weight Mc in the storage device 52. Also, the information acquisition unit 512 acquires the delivery number and the information of the weight Md of the product set 26 from the server 20 of Company B. The information acquisition unit 512 stores the information of the delivery number and the weight Md in the storage device 52.

[0050] The apportionment unit 513 reads out the total power consumption Etotal, the delivery number, and the information of the weights Mc and Md from the storage device 52. The apportionment unit 513 apportions the total power consumption Etotal based on the weight ratio of the product set 16 and the product set 26. The apportionment unit 513 calculates the power consumption E1 allocated to the product set 16 according to the following formula (3). Also, the apportionment unit 513 calculates the power consumption E2 allocated to the product set 26 according to the following formula (4).

[0051] E1 = Etotal × Mc / (Mc + Md) ··· (3) E2 = Etotal × Md / (Mc + Md) ··· (4) The apportionment unit 513 outputs the calculated power consumption E1 and power consumption E2, associated with the corresponding delivery number, to the CO2 emission calculation unit 514.

[0052] The CO2 emission calculation unit 514 reads out the first conversion formula from the storage device 52. The CO2 emission calculation unit 514 inputs the power consumption E1 into the first conversion formula and calculates the CO2 emission Qm1 emitted by the transportation of the product set 16 from Station A 6 to Station B 7. Also, the CO2 emission calculation unit 514 inputs the power consumption E2 into the first conversion formula and calculates the CO2 emission Qm2 emitted by the transportation of the product set 26 from Station A 6 to Station B 7. The CO2 emission calculation unit 514 outputs the CO2 emissions Qm1 and Qm2 to the storage unit 515.

[0053] The storage unit 515 stores the CO2 emissions Qm1 and Qm2, associated with the corresponding delivery number, in the storage device 52.

[0054] Figure 4 is a flowchart showing the procedure of a process for calculating the amount of CO2 emissions discharged by transportation by the transportation railway 5, which is executed by the control device 51. This flowchart is started, for example, when it is detected that the delivery to Company C and Company D has been completed. The completion of the delivery to Company C and Company D may be determined, for example, based on the position information of the transport vehicles 9C and 9D, based on the arrival of the transport vehicles 9C and 9D at the sites of Company C and Company D, respectively. Alternatively, the control device 51 may determine the completion of the delivery to Company C and Company D based on receiving a notification of the completion of delivery from the terminal devices for the delivery personnel respectively associated with the transport vehicles 9C and 9D. Each step (hereinafter, steps are abbreviated as "S") of the flowcharts shown in Figure 4 and Figure 6 described later will be described for the case where they are realized by software processing by the control device 51, but a part or all of them may be realized by hardware (electric circuit) fabricated in the control device 51.

[0055] In S1, the control device 51 acquires, via the communication device 53, the information on the delivery number and the weight Mc of the product set 16 from the server 10 of Company A. Further, the control device 51 acquires, via the communication device 53, the information on the delivery number and the weight Md of the product set 26 from the server 20 of Company B. The control device 51 stores the information on the delivery number and the weight Mc of the product set 16, and the information on the delivery number and the weight Md of the product set 26 in the storage device 52.

[0056] In S2, the control device 51 acquires, via the communication device 53, the information on the power consumption from the transportation railway 5, and integrates the power consumption acquired until the transportation railway 5 moves from Station A 6 to Station B 7. The control device 51 calculates the integrated power consumption as the total power consumption Etotal. The control device 51 stores, for example, the total power consumption Etotal in the storage device 52.

[0057] In S3, the control device 51 reads out the total power consumption Etotal, the information on the delivery number and weight Mc of the product set 16, and the information on the delivery number and weight Md of the product set 26 from the storage device 52. The control device 51 apportions the total power consumption Etotal based on the weight ratio of the product set 16 and the product set 26. Specifically, the control device 51 calculates the power consumption E1 assigned to the product set 16 and the power consumption E2 assigned to the product set 26 according to the above-mentioned formulas (3) and (4), respectively.

[0058] In S4, the control device 51 reads out the first conversion formula from the storage device 52, inputs the power consumption E1 into the first conversion formula, and calculates the CO2 emission amount Qm1 discharged by the transportation of the product set 16 from station A6 to station B7. Further, the control device 51 inputs the power consumption E2 into the first conversion formula and calculates the CO2 emission amount Qm2 discharged by the transportation of the product set 26 from station A6 to station B7.

[0059] In S5, the control device 51 associates the CO2 emission amounts Qm1 and Qm2 with the corresponding delivery numbers and stores them in the storage device 52. More specifically, the control device 51 stores the CO2 emission amount Qm1 in the storage device 52 in association with the delivery number of the product set 16. The control device 51 stores the CO2 emission amount Qm2 in the storage device 52 in association with the delivery number of the product set 26.

[0060] As described above, when calculating the CO2 emission amount in the transportation process, the management center 50 according to the first embodiment apportions, in the transportation section where products are mixed (in the first embodiment, the section from station A6 to station B7), the energy amount consumed in the transportation of the transportation section (in the first embodiment, the power consumption consumed by the transportation railway 5), based on the weight ratio of the mixed products. By apportioning the energy amount based on the weight ratio, the CO2 emission amount in the transportation process for each product can be appropriately calculated.

[0061] In addition, for example, in the case where there is a transportation section in the transport vehicle 9 where products are mixedly loaded, the fuel consumption F in the transportation section may be allocated according to the weight ratio of the mixed products.

[0062] [Modification Example 1] In Embodiment 1, the amount of energy consumed in the transportation section where products are mixedly loaded is allocated based on the weight ratio of the mixed products, and the allocated amount of energy is converted into the CO2 emission amount using the conversion formula respectively. However, the order of conversion of the energy amount to the CO2 emission amount and the allocation does not matter. For example, the amount of energy consumed in the transportation section where products are mixedly loaded may be converted into the CO2 emission amount, and then the converted CO2 emission amount may be allocated to the product set 16 and the product set 26 based on the weight ratio of the mixed products. Modification Example 1 can also be combined with Modification Examples 2 and 3 and Embodiment 2 described later.

[0063] [Modification Example 2] In Embodiment 1, an example where the transport vehicle 9 is a vehicle equipped with an internal combustion engine has been described. However, the transport vehicle 9 is not limited to a vehicle equipped with an internal combustion engine. For example, the transport vehicle 9 may be an electric vehicle. In this case, the transport vehicle 9 includes a battery and a drive device that is driven using the power of the battery. When the transport vehicle 9 is an electric vehicle, instead of the fuel consumption, the power consumption may be used to calculate the CO2 emission amount discharged by the transport by the transport vehicle 9.

[0064] Also, in Embodiment 1, the transport railway and the transport vehicle have been described as examples of moving bodies, but the moving body is not limited to the transport railway and the transport vehicle. The moving body may be, for example, a two-wheeled vehicle, an aircraft, a helicopter, etc.

[0065] [Modification Example 3] In the management system 100, it is also conceivable to share information between enterprises using distributed ledger technology. In this case, the servers 10 to 40 and the management center 50 function as nodes, and each node transmits transaction data including various types of information subject to notification and reporting to the distributed ledger network. For example, a distributed ledger infrastructure that can limit the sharing range of transaction data to the parties involved may be adopted. By exchanging information using distributed ledger technology, the tamper resistance of the information can be enhanced.

[0066] [Embodiment 2] In Embodiment 1 and Modification Examples 1 to 3, an example was described in which the product set 16 and the product set 26 are loaded onto the transport railway 5 at the same station and transported to the same station. However, the product set 16 and the product set 26 may be loaded onto the transport railway 5 at different stations from each other, or may be unloaded from the transport railway 5 at different stations from each other. In Embodiment 2, as an example, an example in which the product set 16 and the product set 26 are unloaded from the transport railway 5 at different stations from each other will be described.

[0067] FIG. 5 is an overall configuration diagram of the management system 100A according to Embodiment 2. Note that the hardware configuration diagram of the management system 100A is the same as that of FIG. 2.

[0068] Referring to FIG. 5, similar to Embodiment 1, the management center 50 receives a transportation request for the product set 16 from the server 10 of Company A. The server 10 notifies the management center 50 of the delivery number and weight information of the product set 16. Further, the management center 50 receives a transportation request for the product set 26 from the server 20 of Company B. The server 20 notifies the management center 50 of the delivery number and weight information of the product set 26.

[0069] Transport vehicles 9A and 9B receive product sets 16 and 26 at factory 1 of Company A and factory 2 of Company B, respectively. Transport vehicle 9A transports product set 16 from factory 1 of Company A to Station A6. Transport vehicle 9B transports product set 26 from factory 2 of Company B to Station A6. Product sets 16 and 26 are loaded together on transport railway 5 and transported from Station A6. In Embodiment 2, product set 26 is unloaded at Station C8 between Station A6 and Station B7. At Station C8, product set 26 is loaded onto transport vehicle 9D and delivered to factory 4 of Company D. On the other hand, product set 16 is transported from Station C8 to Station B7. At Station B7, product set 16 is loaded onto transport vehicle 9C and delivered to factory 3 of Company C.

[0070] That is, on transport railway 5, product sets 16 and 26 are loaded together in the transport section from Station A6 to Station C8, and only product set 16 is loaded in the transport section from Station C8 to Station B7. Hereinafter, the transport section where products are loaded together, that is, the transport section from Station A6 to Station C8, is also referred to as the "first section", and the transport section where products are not loaded together, that is, the "transport section" from Station C8 to Station B7, is also referred to as the second section.

[0071] The control device 51 of the management center 50 accumulates the information on the power consumption obtained from transport railway 5, and accumulates the power consumption (hereinafter also referred to as the "power consumption in the first section") Eja during the movement of transport railway 5 from Station A6 to Station C8. Further, the control device 51 accumulates the power consumption (hereinafter also referred to as the "power consumption in the second section") Ejb during the movement of transport railway 5 from Station C8 to Station B7.

[0072] The control device 51 apportions the power consumption Eja in the first section based on the weight ratio of product sets 16 and 26. The control device 51 calculates the power consumption Eja1 in the first section allocated to product set 16 according to the following formula (5). Further, the control device 51 calculates the power consumption Eja2 in the first section allocated to product set 26 according to the following formula (6).

[0073] Eja1 = Eja × Mc / (Mc + Md) ··· (5) Eja2 = Eja × Md / (Mc + Md) ··· (6) Next, the control device 51 apportions the power consumption Ejb in the second section based on the weight ratio of the product set 16 and the product set 26. The control device 51 calculates the power consumption Ejb1 in the second section assigned to the product set 16 according to the following formula (7). Also, the control device 51 calculates the power consumption Ejb2 in the second section assigned to the product set 26 according to the following formula (8).

[0074] Ejb1 = Ejb × Mc / (Mc + Md) ··· (7) Ejb2 = Ejb × Md / (Mc + Md) ··· (8) In the second section, since the product set 26 is not loaded on the transport railway 5, Md is zero.

[0075] The control device 51 calculates the power consumption E1, which is the allocation of the power consumption consumed in the transport section (the first section and the second section) by the transport railway 5 to the product set 16, according to the following formula (9). Also, the control device 51 calculates the power consumption E2, which is the allocation of the power consumption consumed in the transport section by the transport railway 5 to the product set 26, according to the following formula (10).

[0076] E1 = Eja1 + Ejb1 ··· (9) E2 = Eja2 + Ejb2 ··· (10) The control device 51 reads the first conversion formula from the storage device 52, inputs the power consumption E1 into the first conversion formula, and calculates the CO2 emission amount Qm1 emitted by the transportation of the product set 16 by the transport railway 5. Also, the control device 51 inputs the power consumption E2 into the first conversion formula and calculates the CO2 emission amount Qm2 emitted by the transportation of the product set 26 by the transport railway 5.

[0077] The control device 51 associates the CO2 emissions Qm1 and Qm2 with the corresponding delivery numbers and stores them in the storage device 52. Using the CO2 emissions Qm1 and Qm2 stored in the storage device 52, the control device 51 calculates the CO2 emissions Qt1set in the transportation process of product set 16 and the CO2 emissions Qt2set in the transportation process of product set 26 according to the above formulas (1) and (2).

[0078] Note that the CO2 emissions Qa emitted by transporting product set 16 from factory 1 of Company A to Station A 6, the CO2 emissions Qb emitted by transporting product set 26 from factory 2 of Company B to Station A 6, the CO2 emissions Qc emitted by transporting product set 16 from Station B 7 to factory 3 of Company C, and the CO2 emissions Qd emitted by transporting product set 26 from Station C 8 to factory 4 of Company D can be calculated using the fuel consumption Fa to Fd and the second conversion formula as described in Embodiment 1.

[0079] Figure 6 is a flowchart showing the procedure of the process for calculating the CO2 emissions emitted by transportation by the transportation railway 5, which is executed by the control device 51. This flowchart is started, for example, when it is detected that the deliveries to Company C and Company D are completed.

[0080] In S10, the control device 51 acquires, via the communication device 53, the information on the delivery number and weight Mc of product set 16 from the server 10 of Company A. Further, the control device 51 acquires, via the communication device 53, the information on the destination of product set 16 from the server 10 of Company A. Also, the control device 51 acquires, via the communication device 53, the information on the delivery number and weight Md of product set 26 from the server 20 of Company B. Further, the control device 51 acquires, via the communication device 53, the information on the destination of product set 26 from the server 20 of Company B. The control device 51 stores in the storage device 52 the information on the delivery number of product set 16, the weight Mc, and the destination of product set 16, as well as the information on the delivery number of product set 26, the weight Md, and the destination of product set 26.

[0081] Note that the control device 51 can determine the station at which the product sets 16 and 26 are unloaded from the transport railway 5 based on the information on the destinations of the product set 16 and the information on the destination of the product set 26. Here, the station at which the product set 16 is unloaded from the transport railway 5 is determined to be Station B 7, and the station at which the product set 26 is unloaded from the transport railway 5 is determined to be Station C 8. Therefore, the control device 51 can recognize that the product sets 16 and 26 are mixedly loaded on the transport railway 5 in the section from Station A 6 to Station C 8 (the first section), and only the product set 16 is loaded on the transport railway 5 in the section from Station C 8 to Station B 7 (the second section).

[0082] In S11, the control device 51 acquires the information on the power consumption from the transport railway 5 via the communication device 53, and integrates the power consumption consumed by the transport railway 5 during the movement from Station A 6 to Station C 8 (the first section). That is, the control device 51 calculates the power consumption Eja in the first section. The control device 51 stores the power consumption Eja in the first section in the storage device 52.

[0083] In S12, the control device 51 apportions the power consumption Eja in the first section based on the weight ratio of the product set 16 and the product set 26. Specifically, according to the above formulas (5) and (6), the power consumption Eja1 in the first section allocated to the product set 16 and the power consumption Eja2 in the first section allocated to the product set 26 are calculated.

[0084] In S13, the control device 51 acquires the information on the power consumption from the transport railway 5 via the communication device 53, and integrates the power consumption consumed by the transport railway 5 during the movement from Station C 8 to Station B 7 (the second section). That is, the control device 51 calculates the power consumption Ejb in the second section.

[0085] In S14, the control device 51 apportions the power consumption Ejb in the second period based on the weight ratios of product set 16 and product set 26. Specifically, according to the above formulas (7) and (8), it calculates the power consumption Ejb1 in the second period allocated to product set 16 and the power consumption Ejb2 in the second period allocated to product set 26. In this case, the control device 51 sets the weight Md to zero.

[0086] In S15, the control device 51 calculates, according to the above formulas (9) and (10), the power consumption E1 which is the allocation of the power consumption consumed by the transport railway 5 to product set 16, and the power consumption E2 which is the allocation of the power consumption consumed by the transport railway 5 to product set 26, respectively.

[0087] In S16, the control device 51 reads the first conversion formula from the storage device 52, inputs the power consumption E1 into the first conversion formula, and calculates the CO2 emission amount Qm1 emitted by transporting product set 16 by the transport railway 5. The control device 51 inputs the power consumption E2 into the first conversion formula and calculates the CO2 emission amount Qm2 emitted by transporting product set 26 by the transport railway 5.

[0088] In S17, the control device 51 associates the CO2 emission amounts Qm1 and Qm2 with the corresponding delivery numbers and stores them in the storage device 52. More specifically, the control device 51 associates the CO2 emission amount Qm1 with the delivery number of product set 16 and stores it in the storage device 52. The control device 51 associates the CO2 emission amount Qm2 with the delivery number of product set 26 and stores it in the storage device 52.

[0089] As described above, when the product set 16 and the product set 26 are unloaded from the transport railway 5 at different stations, the management center 50 according to the second embodiment divides the transport section transported by the transport railway 5 into a first section where the product set 16 and the product set 26 are mixed and a second section where the product set 16 and the product set 26 are not mixed. Then, the management center 50 apportions the power consumption (energy amount) consumed in each section based on the weight ratio of the products being mixed. Thereby, even when the product set 16 and the product set 26 are unloaded from the transport railway 5 at different stations, the CO2 emissions in each section can be appropriately calculated.

[0090] In the above description, an example where two sets (products) of the product set 16 and the product set 26 are mixed on the transport railway 5 has been described. However, the number of sets mixed on the transport railway 5 may be three or more. For example, when three sets are mixed on the transport railway 5, the transport section may be divided into a section where three sets are mixed, a section where two sets are mixed, and a section where one set is loaded. Alternatively, the section may be divided based on the stopping stations of the transport railway 5. For example, assume that the transport railway 5 transports products from the starting station A to the terminal station B and stops at intermediate stations C and D between station A and station B. In this case, the transport section by the transport railway 5 can be divided into a section from station A to station C, a section from station C to station D, and a section from station D to station B. The power consumption can be allocated to each product based on the weight ratio of the products loaded in each section.

[0091] Furthermore, for example, a case is also conceivable where one transport vehicle 9 loads the product set 16 at the factory 1 of Company A, then loads the product set 26 at the factory 2 of Company B, and transports the product set 16 and the product set 26 to the station A 6. In such a case, for the transport vehicle 9 as well, the transport section may be divided into a section from the factory 1 to the factory 2 and a section from the factory 2 to the station A 6, and the fuel consumption may be apportioned based on the weight ratio. Thereby, the CO2 emissions discharged by the transport by the transport vehicle 9 can be appropriately apportioned.

[0092] The embodiments disclosed this time should be considered illustrative in all respects and not restrictive. The scope of the present disclosure is indicated by the scope of claims rather than the above description, and it is intended that all modifications within the meaning and scope equivalent to the scope of claims be included.
