Various companies, including those in the manufacturing industry, are required to conduct their business activities in consideration of environmental indicators such as _CO2 emissions. Regarding CO ₂ emissions of companies, there is a way of thinking that uses an index called supply chain emissions to evaluate CO ₂ emissions in the entire supply chain. A company's (buyer's) supply chain emissions include indirect CO ₂ emissions from purchasing products from other companies (suppliers). Therefore, it is required that the purchase order contract under which the buyer procure the product from the supplier takes into consideration not only the price and the delivery date but also the environmental index.

However, since the system disclosed in Patent Document 1 evaluates the environmental impact of ICT services, it does not consider sales contracts, and is not suitable for considering environmental indicators in sales contracts.

One of the purposes of this disclosure is to provide a technique for arbitrating orders and orders contracts in consideration of environmental indicators.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of the contract mediation system of this embodiment. The contract mediation system has a contract mediation device 10 and an operation terminal 20 .

The contract arbitration system has a contract arbitration device 10 and a plurality of operation terminals 20. The operation terminal 20 can be connected to the contract mediation device 10 via the network 70 .

The contract arbitration device 10 is a device that supports an order placement contract exchanged between a supplier and a buyer. The contract arbitration device 10 makes it possible to conclude an order placement contract in consideration of environmental indicators in addition to price and delivery date when procuring goods. Specific examples of environmental indicators include _CO2 emissions and power consumption.

The supplier 31 is a company that manufactures and sells its own products. The buyer 21 is a company that purchases goods from the supplier 31 and uses them in its own products. For example, the buyer 21 incorporates an article purchased from the supplier 31 into its own product as a component. In addition, there are further suppliers (lower level suppliers 32) below the supplier 31, and the suppliers 31 may purchase goods from the lower level suppliers 32 and use them for their own products. These buyer 21, supplier 31, and subordinate supplier 32 are system users of the contract mediation system.

In the example of FIG. 1, companies A to N are system users as buyers 21, company AA is a system user as supplier 31, and company NN is a system user as a subordinate supplier. The operation terminal 20 is a terminal device used by each system user. The buyer 21, the supplier 31, and the subordinate supplier 32, who are users of the system, can use the service provided by the contract arbitration device 10 via the operation terminal 20 to conclude an order placement contract.

FIG. 2 is a block diagram showing the software configuration of the contract mediation device. The contract arbitration device 10 has a user management section 101 and a contract adjustment section 102 .

The user management unit 101 provides a user interface for inputting information to system users who use the contract arbitration system, and records the input information as user information 111 . For example, the user management unit 101 provides the supplier 31 with a user interface for inputting desired order conditions in advance, and records the input information as the user information 111 . The details of the user interface for inputting the desired order conditions will be described later.

The user information 111 includes information on each of the buyer 21, the supplier 31, and the subordinate supplier 32. The user information of the supplier 31 includes desired order conditions that the supplier 31 desires when receiving an order for an article that is its own product. The desired order conditions are conditions related to a plurality of condition items including an environmental index, which is an index relating to the environmental impact of providing the item to the buyer 21 .

FIG. 3 is a diagram showing an example of information on desired order conditions. The desired order condition information 114 includes "company ID", "item", "purchase unit", "delivery date", "standard consumption", "adjustable value", "priority information", and "renewable energy usage information". ” is registered.

"Company ID" is identification information that identifies the supplier 31. The "item" is the item of the goods covered by the ordering contract. The "purchase unit" is the minimum number of items that should be purchased at once. The “delivery date” is the period required for delivery of the goods.

"Standard Consumption" is the standard resource consumption caused by providing the item. Standard resource consumption means resource consumption when renewable energy is not used. Resource consumption, like _CO2 emissions, is an environmental indicator. Resource consumption and _CO2 emissions can be converted to each other. As for the resource consumption amount, further details may be set so as to be used in the environmental index management process described later. For example, the amount of resource consumption for manufacturing the article, the amount of resource consumption for delivery of the article, and the amount of resource consumption in the upstream process of the article used as a part or the like for the article may be set.

"Adjustable value" is the amount of resource consumption that can be adjusted by using renewable energy.

"Priority information" is information that indicates the items that the supplier prioritizes in the ordering contract for the goods. ">" in the figure indicates the order of priority. For example, "consumption>delivery date>unit price" means that the supplier gives priority to delivery date over unit price and resource consumption over delivery date when receiving an order for the item. For example, giving priority to the delivery date over the unit price means that if a concession is necessary for any item in order to complete the ordering contract, the lower-priority unit price will be conceded before the delivery date. do.

"Renewable energy usage information" indicates whether it is possible to reduce resource consumption by using renewable energy in providing the item. "Possible" means that the supplier can use renewable energy in manufacturing, transportation, etc. of the item. "Provision Acceptable" indicates that the resource consumption of the product can be reduced by receiving the provision of rights related to environmental indicators and claiming the rights. The provision of rights related to environmental indicators is, for example, the provision of renewable energy certificates such as green power certificates.

The user management unit 101 also provides the buyer 21 and the supplier 31 with a user interface for checking the supply chain emissions. For example, the supply chain emissions of the buyer 21 include the CO ₂ emissions at the supplier 31 of the parts that the buyer 21 procures from the supplier 31 and incorporates into its products. The relationship can be confirmed on the user interface screen. The details of the user interface for checking supply chain emissions will be described later.

The contract adjustment unit 102 executes contract arbitration processing. The contract arbitration process determines the supplier 31 to be the contract destination of the buyer 21 and the contract content of the contract based on the desired order conditions presented by the buyer 21 and the desired order conditions registered in advance by the supplier 31. This is the process of specifying. For example, the contract adjustment unit 102 identifies the supplier 31 who has registered the desired order conditions satisfying the desired order conditions of the buyer 21 as the buyer 21's contract partner.

FIG. 4 is a diagram showing an example of information on desired order conditions. "Order number", "company ID", "item", "quantity", "delivery date", "consumption", "priority information", and "renewable energy provision information" are registered in the desired order condition information 113. be done.

"Purchase order number" is a number that identifies the order subject to the ordering contract. "Company ID" is identification information of the buyer 21 who intends to enter into an order placement contract. The "item" is the item of the goods covered by the ordering contract. "Quantity" is the number of the goods to be purchased in the ordering contract.

"Delivery date" is the desired delivery date of the item. The "consumption amount" is a desired resource consumption amount caused by the supplier 31 providing the item. The desire of the supplier 31 is that the resource consumption is below the desired value.

"Priority information" is information that indicates the items that the buyer prioritizes in the ordering contract for the goods. ">" in the figure indicates the order of priority. For example, "consumption>delivery date>unit price" means that the buyer gives priority to delivery date over unit price and resource consumption over delivery date when ordering the item. For example, giving priority to the delivery date over the unit price means that if a concession is necessary for any item in order to complete the ordering contract, the lower-priority unit price will be conceded before the delivery date. do.

"Renewable energy provision information" indicates whether rights related to environmental indicators can be provided in order to reduce renewable energy when receiving the provision of the product. The provision of rights related to environmental indicators is, for example, the provision of renewable energy certificates such as green power certificates. "Yes RE001" means that the rights related to environmental indicators can be provided, and the identification information of the rights, for example, the certificate number is RE001.

Upon receiving the desired order terms information 113 from the buyer 21, the contract adjustment unit 102 refers to the desired order terms in the user information 111 of each supplier 31 registered in advance, and obtains the desired order terms indicated in the desired order terms information 113. A search is made for a supplier 31 registering desired order conditions satisfying the conditions, and when found, the supplier 31 is specified as a contract partner.

The determination of each conditional item is roughly performed as follows.

If the "item" of the desired order condition information 113 and the "item" of the user information 111 match, the condition item is satisfied. If the "quantity" in the desired order condition information 113 is a multiple of the "purchase unit" in the user information 111, the condition item is satisfied. If the "delivery date" of the desired ordering condition information 113 is before the date obtained by adding the "delivery date" of the user information 111 to the current date, the condition item is satisfied.

If the "standard consumption amount" of the user information 111 is equal to or less than the "consumption amount" of the desired order condition information 113, the condition item is satisfied without using renewable energy. Even if the "standard consumption amount" of the user information 111 exceeds the "consumption amount" of the desired order condition information 113, the "renewable energy information" of the user information 111 is "possible" and the "standard consumption amount is less than or equal to the "consumption" of the desired order condition information 113, the condition is satisfied by using renewable energy. In addition, even if the "standard consumption amount" of the user information 111 exceeds the "consumption amount" of the desired order condition information 113, the "renewable energy supply" of the desired order condition information 113 is "possible", If the “renewable energy information” of the person information 111 is “provided and accepted”, the provision of the right related to the environmental index satisfies the condition.
Details of the contract mediation process will be described later.

When the contract adjustment unit 102 finds the desired order conditions that satisfy the desired order conditions and identifies the contracting party, it generates contract information 112 indicating the content of the order/order contract between the buyer 21 and the supplier 31 .

FIG. 5 is a diagram showing an example of contract information. In the contract information 112, "contract ID", "ordering company ID", "order receiving company ID", "item", "quantity", "emission amount", "delivery date", and "certificate number" are registered.

"Contract ID" is identification information of the order acceptance contract. The “ordering company ID” is identification information of the buyer 21 who is the company that placed the order for the order-receiving contract. The "accepting company ID" is identification information of the supplier 31 that has become the contracted company of the order receiving/ordering contract. The “item” is the item of the goods covered by the order-ordering contract. "Quantity" is the number of articles purchased in the relevant ordering contract. "Emissions" is the _CO2 emissions from goods traded under the relevant ordering contract. _CO2 emissions are converted from resource consumption. The “delivery date” is the scheduled delivery date of the goods traded according to the order-ordering contract. The “certificate number” is the identification number of the renewable energy certificate provided to the contracted company that receives the order from the ordering company that orders the goods in the ordering contract.

In addition, the contract adjustment unit 102 executes a process (environmental indicator management process) that supports the system user's environmental indicator management. The environmental index management process is a process of displaying a list of the environmental index values of the order placement contract or tabulating them. System users such as the buyer 21 and the supplier 31 can easily confirm the company's supply chain emissions.

FIG. 6 is a block diagram showing the hardware configuration of the contract mediation device.

The contract arbitration device 10 is a general computer such as a server device as hardware, and is connected to the operation terminal 20 via a network 70 such as the Internet.

The contract arbitration device 10 has, as hardware, a main control unit 231 , a main storage unit 234 , an input unit 235 , an output unit 236 and a communication unit 237 , which are interconnected via a bus 238 .

The main storage unit 234 is a device that stores data in a writable and readable manner.

The main control unit 231 includes a processor 232 and RAM (Random Access Memory), and the processor 232 uses the RAM 233 as appropriate to execute software program processing. User management unit 101 and contract adjustment unit 102 shown in FIG. 2 are implemented by main control unit 231 executing a software program.

The communication unit 237 transmits information processed by the main control unit 231 via the network 70 including wired or wireless or both, and also transmits information received via the network 70 to the main control unit 231 . The received information is used by the main control unit 231 for software program processing.

The input unit 235 is a device that receives information input by an operator such as a keyboard or mouse, and the input information is used by the main control unit 231 for software program processing.

The output unit 236 is a device that displays image and text information on the display screen in accordance with the processing by the main control unit 231 .

FIG. 7 is a flowchart of contract mediation processing.

In step S101, the user management unit 101 provides the supplier 31 and the subordinate supplier 32 with a user interface for inputting desired order conditions, acquires the desired order conditions from the supplier 31 and the subordinate supplier 32, and stores user information. Set to 111.

FIG. 8 is a diagram showing an example of a user interface for inputting desired order conditions.

The desired order condition setting screen shown in FIG. 8 is a screen for the supplier 31 to register the user information 111 including the desired order condition for the company's products. When information is input from this screen, the user information 111 illustrated in FIG. 3 is registered. For example, if a “normal” value for the discharge amount (monthly) is set, it is registered in the “standard consumption amount” in the user information 111 . Furthermore, when the "renewable energy" value of the emission amount (monthly) is entered, the value obtained by subtracting the value set for "renewable energy" from the value set for "normal" is the "adjustable value" in the user information 111. ” is registered. In the Emission Reduction Rate column, the amount of reduction compared to the previous year's actual _CO2 emissions is calculated and displayed for "normal" and "renewable energy." In addition, if a "normal" delivery date and a "renewable energy use" delivery date are set in the delivery date column, the range indicated by the minimum and maximum values is registered in the "delivery date" of the user information 111. . Also, "renewable energy information" in the user information 111 is registered based on the information set in the option column. For example, if a check mark is set for “Renewable energy only when provided by buyer”, “Provided and accepted” is registered in the “Renewable energy information” of the user information 111 . Also, when a standard value and a fluctuation range are set in the unit price column, the unit price information (not shown) is registered in the user information 111 .

Returning to FIG. 7, the contract adjustment unit 102 provides the buyer with a user interface for inputting the desired order conditions. When the buyer 21 sets information on the desired order conditions in step S102, contract adjustment is performed in step S103. The unit 102 acquires information on the desired order conditions.

FIG. 9 is a diagram showing an example of a user interface for inputting desired order conditions.

The desired order condition setting screen shown in FIG. 9 is a screen for registering the desired order condition information 113 when the buyer 21 purchases parts from the supplier 31 . When information is entered from this screen, the desired order condition information 113 illustrated in FIG. 4 is registered.

For example, if a range from the earliest date to the last date is set in the delivery date column, the date set for the earliest date is registered in the "delivery date" of the desired order condition information 113. The date set as the last day is also registered in the desired order condition information 113 (not shown). Also, when a standard value and a fluctuation range are set in the unit price column, the unit price information (not shown) is registered in the desired order condition information 113 . In addition, if a check is set in the "Yes" column in "Provision of power purchase quota to suppliers" and a certificate number is set in "Certificate setting", " Yes" and the certificate number are registered.

In addition, an annual target value for CO ₂ emissions can be set in the column of "emissions (annual)", or no specification can be selected. When the target value is set, the target value information (not shown) is registered in the desired order condition information 113 . In addition, a target value for the annual reduction rate of CO ₂ emissions can be specified in the "Emission Reduction Rate" column, or no specification can be selected. When the target value is specified, the information (not shown) of the target value is registered in the desired order condition information 113 . In addition, in the "Electricity Designation" column, "renewable energy" and "green power" can be checked, or no designation can be selected. When “renewable energy” is specified, information (not shown) indicating that use of renewable energy is desired is registered in the desired order condition information 113 . When "renewable energy" is checked, information (not shown) indicating a desire to use renewable energy is registered in the desired order condition information 113 . When "green power" is checked, information (not shown) indicating a desire to use green power is registered in the desired order condition information 113. FIG.

Returning to FIG. 7, in steps S104-105, the contract adjustment unit 102 compares the desired order acceptance terms of the user information 111 of each supplier 31 with the desired order terms of the buyer's 21 desired order terms information 113, It is determined whether or not there is a supplier 31 that satisfies the conditions regarding resource consumption of 21. If the buyer 21 does not set the resource consumption condition in the desired order condition information 113, it is assumed that all suppliers 31 who can provide the item satisfy the resource consumption condition. For example, if no value is set in the item "consumption amount" in the desired order condition information 113 illustrated in FIG. It may be treated as satisfying the resource consumption condition in the desired condition.

If a supplier 31 whose "standard consumption amount" of the user information 111 is equal to or less than the value obtained by normalizing the "consumption amount" of the desired order condition information 113 by "quantity" is found, the condition regarding the resource consumption amount of the buyer 21 is satisfied. It is determined that there is a supplier 31. If such a supplier 31 is not found, it is determined that there is no supplier 31 that satisfies the condition regarding the resource consumption of the buyer 21 .

If it is determined that there is no supplier 31 that satisfies the condition regarding the resource consumption of the buyer 21, the contract adjustment unit 102 can change the condition regarding the resource consumption in the desired order condition information 113 of the buyer 21 in step S106. Determine whether it is possible or not. For example, in the priority information of the desired order condition information 113, if the priority of "consumption" is a predetermined order or less and the value added to the "consumption" is a predetermined value or less, the desired order condition information 113 of the buyer 21 It may be determined that it is possible to change the resource consumption condition in .

In step S106, if it is not possible to change the resource consumption condition in the buyer's 21 desired order condition information 113, the contract will not be concluded. A notice to the effect that a review of the conditions is urged is sent to the buyer 21, and the contract arbitration process ends.

In step S106, if it is possible to change the condition regarding the resource consumption in the buyer's desired order condition information 113, the contract adjustment unit 102 relaxes the condition regarding the resource consumption of the buyer 21 in step S107. do. For example, a value obtained by adding a predetermined value to the value of "consumption" in the desired order condition information 113 may be used as the new "consumption" value.

At this time, the contract adjustment unit 102 refers to the priority information in the desired order condition information 113, presents the option of the relaxation method of the condition to the buyer 21 according to the information set there, and the buyer 21 selects the option. You may choose to relax the conditions in an optional way.

Subsequently, in step S108, the contract adjustment unit 102 determines whether or not adjustment of contract conditions with the supplier 31 is required. For example, if a supplier 31 that satisfies the relaxed resource consumption condition is found in step S107, it may be determined that adjustment is unnecessary, and if such a supplier 31 is not found, it may be determined that adjustment is required. .

When it is determined in step S108 that adjustment is required, the contract adjustment unit 102 notifies each supplier 31 of the relaxed resource consumption condition in step S107, and sends it to the supplier 31 via the user interface. Prompts to determine whether the condition is acceptable.

In step S109, if the supplier 31 determines that it is possible to accept the relaxed conditions regarding resource consumption, in step S112, the supplier 31 accepts the resource requirements in the desired order conditions included in its own user information 111. The value of the condition item regarding the consumption amount is changed so as to satisfy the relaxed condition regarding the resource consumption amount, and the contract arbitration device 10 is notified to that effect.

On the other hand, if the supplier 31 determines in step S109 that it is not possible to accept the relaxed resource consumption conditions, in step S110 the supplier 31 sends relax the resource consumption conditions required for it, and notify the subordinate suppliers of the conditions that have been relaxed. In step S111, the lower supplier 32 determines whether or not it is possible to accept the relaxed conditions. If the conditions are acceptable, the supplier 31 is notified of the acceptance.

The supplier 31, having received the notification from the lower supplier 32 that the conditions are acceptable, in step S112, based on the conditions accepted by the lower supplier 32, fills in the condition items related to resource consumption in its own user information 111. The value is changed so as to satisfy the condition regarding the resource consumption relaxed by the buyer 21, and the contract arbitration device 10 is notified to that effect.

All the suppliers 31 and lower suppliers 32 perform the operations from step S109 to step S112. After that, in step S113, the contract adjustment unit 102 determines whether there is a supplier 31 that satisfies the relaxed resource consumption condition. In step S112, if there is a supplier 31 that has changed the condition for the relaxed resource consumption and notified the contract arbitration device 10 to that effect, the supplier 31 that satisfies the relaxed condition for the resource consumption. It should be determined that there is

If it is determined in step S113 that there is no supplier 31 that satisfies the relaxed resource consumption conditions, the contract adjustment unit 102 returns to step S106.

On the other hand, if it is determined in step S113 that there is a supplier 31 that satisfies the relaxed condition regarding resource consumption, the contract coordination unit 102 determines in step S114 that the supplier 31 and the buyer meet the relaxed condition regarding resource consumption. 21, and the difference in each condition item between the specified contents and the initial desired order condition information 113 of the buyer 21 is calculated. Here, as an example, the content of the supplier's 31 desired order conditions, including the value of the accepted condition item related to resource consumption, is specified as the content of the ordering contract. The difference is calculated for each condition item of resource consumption, delivery date, and unit price. In the desired order condition information 113, if the delivery date is set by the earliest date and the last date, the earliest date is used to calculate the difference. Also, in the desired order condition information 113, if the unit price is set by the standard value and the fluctuation range, the standard value is used to calculate the difference. If there are multiple suppliers 31 that satisfy the relaxed resource consumption condition, the difference is calculated for all of the suppliers 31 .

Subsequently, in step S115, if there are a plurality of suppliers 31 who satisfy the relaxed condition regarding resource consumption, the contract adjustment unit 102 selects the resource consumption, delivery date, and unit price from the desired order condition information 113 of the buyer 21. The supplier 31 with the smallest difference in the items with the highest priority indicated in the priority information is specified as the contract partner.

Furthermore, in step S116, the contract coordination unit 102 notifies the supplier 31 and the buyer 21 of the contents of the order placement contract between the identified supplier 31 and the buyer 21.

Note that in this embodiment, when the condition regarding the resource consumption of the desired order condition is relaxed in step S108, the supplier 31 is notified of this fact and the content of the condition, and whether or not the condition can be accepted is determined. It is supposed to ask for judgment, but it will not be used in this example. As another example, after step S107, the process may proceed to step S113 to determine whether or not there is a supplier that satisfies the relaxed conditions.

FIG. 10 is a diagram showing an example of the user interface presented to the buyer after the contract mediation process is executed.

FIG. 10 shows the contents of an order placement contract in which the buyer 21 purchases the item XXX from the supplier 31 with a delivery date of 2021/11/10 and a unit price of 100,000 yen. In the ordering contract, the buyer 21 provides the supplier 31 with a power purchase quota (certificate RE0123), and the power supply amount is 1000/kWh. The delivery date is three days after the buyer's 21 request. The unit price is 10,000 yen higher than the buyer 21's request. "Priority Result" shows the difference between the value in the contract content and the value in the desired order condition for each condition item whose priority is specified in the priority information of the desired order condition. "Emissions OK" means that the buyer's 21 wishes have been met with respect to the CO ₂ emissions conditional item. “Assumed Emissions (Yearly)” displays the current year's forecast of _CO2 emissions related to item xxx. The "emission reduction rate" displays the reduction rate from the actual CO2 emissions of the last fiscal year to the above assumed emissions (annual).

FIG. 11 is a diagram showing an example of the user interface presented to the supplier after the contract mediation process is executed. "Priority Result" indicates the difference between the value in the contract content and the value in the desired order condition for each condition item whose priority is specified in the priority information of the desired order condition. Looking at the "priority result", the unit price in the ordering contract on the supplier 31 side is 10,000 yen higher than the amount desired by the supplier 31, but the delivery date and _CO2 emissions are It is within the desired range of 31.

Also, when a plurality of contract arbitration processes are executed, information on CO ₂ emissions related to those orders and orders contracts is accumulated, and the accumulated information is provided for the environmental index management process. The contract adjustment unit 102 executes environmental index management processing based on the accumulated information on CO ₂ emissions, aggregates and processes the information on CO ₂ emissions, and presents it to the system user through a user interface. do.

FIG. 12 is a diagram showing a table listing monthly total CO ₂ emissions for each item. In this table, "company ID", "item", "monthly emission total", and "addition source contract ID" are described. “Company ID” is identification information of companies such as the buyer 21 and the supplier 31 to be referred to. "Item" is the item of the article to be referred to. "Total monthly emissions" is the total monthly _CO2 emissions for the item in question at the company. For example, 10000 [21/10] indicates that the _CO2 emissions in October 2021 is 1000. The “addition source contract ID” is identification information of each contract in which the CO ₂ emissions are added up in the “total monthly emissions”.

FIG. 13 is a table showing the breakdown of CO ₂ emissions of items for each contract. This table describes "contract ID", "item", "total emission amount", "manufacturing emission amount", "delivery emission amount", and "upstream emission amount".

“Contract ID” is identification information of the contract. "Item" is the item of the article. “Total emissions” is the total amount of _CO2 emissions related to the goods of the item in the contract. “Manufacturing emissions” are the _CO2 emissions associated with the manufacturing of the goods of the relevant item in the relevant contract, and are converted from the amount of resources consumed by the manufacturing of the relevant goods. “Delivery emissions” is the amount of _CO2 emissions associated with the delivery of the goods of the relevant item in the relevant contract, and is converted from the amount of resource consumption due to the delivery of the relevant goods. "Upstream emissions" is the amount of _CO2 emissions in the upstream process of the parts, etc. used for the goods of the item in the contract, and the amount of resource consumption in the upstream process of the goods used as parts, etc. converted. The sum of manufacturing emissions, delivery emissions, and upstream emissions is the total emissions.

FIG. 14 is a diagram showing an example of a user interface for browsing actual emissions. FIG. 14 shows an example of a screen on which a company browses _CO2 emissions related to its products. "YYY" is specified as the product type, "September" is specified as the time range for aggregation, and "3%" is specified as the reduction target. The pie chart shows the percentage of _CO2 emissions of the company's products containing "YYY".
