The storage unit 13 may be provided outside the information processing device 1 and accessed from the information processing device 1 . Storage unit 13 includes an order information DB.

The information processing method by the information processing apparatus 1 will be described in detail below.

The control unit 11 of the information processing device 1 acquires order information for steel-related products. Steel-related products include, but are not limited to, slag or steel products, for example. The order information may be acquired by being received from another information processing device via the network and the communication unit 12, or may be acquired by being manually input to the information processing device 1. FIG. Order information includes, for example, JIS standards, quantity, or delivery date information.

The control unit 11 determines manufacturing standards for steel-related products. When the steel-related product is a steel material product, the manufacturing specification may include information such as steel grade, product specification, manufacturing route, and product weight. When the steel-related product is slag, the production specification may include information such as product specification, production route, product weight, and the like.

The control unit 11 determines the output amount, slag amount, and rolling amount of the electric furnace EF for manufacturing steel-related products from the determined manufacturing standard. The electric furnace EF will be described with reference to FIG.

The electric furnace EF applies a high voltage to the electrode EL to generate an electric arc EA. The electric furnace EF applies a high voltage to the electrodes EL to generate arc heat, and the arc heat melts, for example, scrap iron. Molten steel MS produced by melting is processed into steel products after going through processes such as composition adjustment, casting and rolling. The steel product may be, but is not limited to, at least one of the following products.
・Deformed bars, flat steel, small and medium shaped steel, H-shaped steel (large shaped steel, steel sheet piles)

As an alternative or an additional example, the electric furnace EF melts and detoxifies the slag raw material in the electric furnace EF at a high temperature with thermal energy from the electric arc EA. The arc temperature is approximately 4,000°C. The slag raw material is melted at about 1,300°C to 1,600°C. The generated slag SG floats above the molten steel MS and has a heat retaining effect. The slag SG in this embodiment is used for at least one of the following purposes, but may be used for other purposes as an alternative.
・Aggregate for asphalt mixture ・Aggregate for concrete ・Road base material ・Soil improvement material

The control unit 11 determines the amount of electric power required to manufacture steel-related products in the electric furnace EF from the output amount, slag amount, and rolling amount of the electric furnace EF. The required amount of power may be calculated by a predetermined formula, or determined by referring to a correspondence table between the amount of steel output, the amount of slag, the amount of rolling, and the amount of power required.

The electric power used in the electric furnace EF of the present embodiment is electric power that does not emit carbon dioxide and is generated from a non-fossil power source such as renewable energy. Renewable energy here refers to the following energy sources.
(1) Solar power (2) Wind power (3) Hydro power (4) Geothermal power (5) Biomass (organic matter derived from animals and plants that can be used as an energy source (excluding crude oil, petroleum gas, combustible natural gas, coal, and products manufactured from these. ).)
(6) In addition to the energy sources listed in 1 to 5 above, among energy sources other than crude oil, petroleum gas, combustible natural gas, coal, and products manufactured from these, those that can be used permanently as an energy source for electricity. Those specified by Cabinet Order as permitted

Non-fossil power sources include, for example, nuclear power as well as renewable energy. Electricity generated from non-fossil power sources includes the following two.
1. Value of electricity itself (kWh value, etc.)
2. Non-Fossil Value In the present embodiment, the "non-fossil value" of the above two values is referred to as non-fossil value. The electric furnace EF uses electric power defined as a non-fossil value. The non-fossil value here is the value recorded as a non-fossil power source when calculating the non-fossil power source ratio in Japan's "Energy Supply Structure Advancement Act". Non-fossil value is the value purchased by new electricity retailers to meet the stated target value.

Power, defined by non-fossil values, is obtainable and verifiable, for example, using at least one of the following three means.
(1) Non-fossil certificate (2) Green power certificate (3) J credit

A non-fossil certificate is a certificate that expresses the environmental value of electricity generated by renewable energy.

A green power certificate is a certificate of the environmental value of power generated by renewable energy. A serial number is attached to the Green Power Certificate, making it unique. The green power certificate includes information on the amount of power generated, the period of power generation, the method of power generation, and the date of issuance of the certificate. The green power certificate further includes information on the name of the certification body and the name of the certificate issuer.

J-credit is a system in which the government certifies the emission reduction amount and absorption amount of greenhouse gases such as carbon dioxide as "credits".

Additionally or alternatively, power defined in non-fossil value may also be obtained and verifiable by the following means.
(4) Power generation using solar power generation equipment owned by the company

As an alternative, the power used in the electric furnace EF may be power defined as a zero-emission value rather than power defined as a non-fossil value. The zero-emission value here is the value for which the carbon dioxide emission coefficient in Japan's "Law Concerning Promotion of Global Warming Countermeasures" (hereinafter referred to as the Global Warming Law) is zero. Specifically, the zero-emission value is calculated by multiplying the amount of electricity from the non-fossil fuel certificates procured by the electricity retailer when calculating the post-adjustment emission factor by the "national average factor". A value that can be subtracted from emissions. When power purchasers such as manufacturers report their carbon dioxide emissions to the government based on the Global Warming Law, the carbon dioxide emission factor for power with zero emission value is zero. For example, electricity defined as zero-emission value may be electricity generated by an existing electricity sales company using renewable energy, such as hydropower, or nuclear power. Power, defined as a zero-emission value, is obtainable and verifiable by the following means.
(5) Contracts with electricity retailers (e.g. “Aqua Premium” (registered trademark) and “Aqua Energy 100” provided by TEPCO Energy Partner (registered trademark))

For each of the means (1) to (5) exemplified above, information such as a certificate certifying that the electric power used in the electric furnace EF is defined as non-fossil value or zero emission value is unique It is obtained from a certificate issuing business or a certification authority as unique certification information. The above means (1) to (5) are examples, and can be replaced by any other means that proves that the electric power used in the electric furnace EF is electric power defined by non-fossil value or zero emission value. be.

In this embodiment, the method for certifying that the electric power used in the electric furnace EF is electric power defined by non-fossil value or zero emission value is to obtain the certification information by any of the above (1) to (5). There is a way to prove

Certification information that certifies that the electric power used in the electric furnace EF is defined as non-fossil value or zero-emission value is purchased at an auction or from an intermediary and stored in the storage unit 13 .

As an additional example, certification information may include non-fossil residue information certified by any manufacturer.

As an example, the purchase amount (order amount) of the certification information in the first auction may be determined as follows, for example. That is, the control unit 11 calculates the economical order quantity that minimizes the sum of the annual order cost and the annual inventory maintenance cost. The annual ordering cost is the cost for ordering the certification information for one year. The larger the order quantity per order, the lower the number of orders placed in a year, so the annual order cost is low. The annual inventory maintenance cost is a system usage fee, personnel cost, or the like required for one year to place an order for certification information. The higher the order quantity per order, the higher the annual inventory maintenance cost because more proof information may remain. As shown in FIG. 3, in the economical order quantity, the annual order cost and the annual inventory maintenance cost are the same. Therefore, the equation shown in FIG. 4 holds true, where Q is the economic order quantity. Although the "power unit" in FIG. 4 is MWh here, it is not limited to this. Transforming the equations shown in FIG. 4 yields the equations shown in FIG. Examples of values substituted into the formula in FIG. 5 are as follows.
Cost per order = 100,000 yen Annual requirement = (Last year's production volume of steel-related products: 10,000 tons) x (636.5 kWh/ton)
= 6,365 MWh/year Annual inventory maintenance cost per power unit = (Purchase cost per 1MWh) x (Capital cost rate)
= ¥300 x 3%
= 9 yen Substituting each value above into the formula in Figure 5, the economic order quantity is 3,756 MWh.

The control unit 11 may determine the calculated economic order quantity as the purchase quantity of the certificate information in the first auction. As an alternative example, the control unit 11 calculates the economic order quantity, the steel material demand index (for example, construction start floor area year-on-year forecast, GDP forecast, etc.), and the carbon-free steel material demand index (global average temperature, number of natural disasters, natural disasters damage cost, national budget for carbon-free measures, etc.), etc., the amount of proof information to be purchased in the first auction may be determined.

As described above, the purchase amount of certification information in the first auction may be determined. However, the method of determining the purchase amount in the first auction is arbitrary.

When the control unit 11 acquires the order information, it stores the order information in the order information DB of the storage unit 13 in association with the required power amount, as shown in FIG.

After reading the certification information from the storage unit 13, the control unit 11 determines whether or not the required amount of power required for manufacturing is within the range of the amount of power certified by the certification information purchased in the first auction (specifically, determines whether or not the required power amount is equal to or less than the certified power amount). As shown in FIG. 6, the determination result may be stored in association with the order information.

When the control unit 11 determines that the required amount of power required for manufacturing is within the range of the certified amount of power, the control unit 11 notifies other information processing apparatuses to start manufacturing steel-related products. Notification may be performed by image or sound. Another information processing device may be, for example, a terminal operated by a person in charge of manufacturing. On the other hand, when the control unit 11 determines that the required amount of power exceeds the range of the certified amount of power, it determines whether the delivery date of the steel-related product is earlier than the date and time of the next auction for purchasing the certification information. do. The date and time of the next auction may be retrieved via the network by the control unit 11, or may be manually input.

When the control unit 11 determines that the delivery date is earlier than the date and time of the next auction, the control unit 11 accesses the terminal of the intermediary through the network and orders and purchases the certificate information. When the purchase of the certificate information is completed, the control unit 11 notifies other information processing devices to start manufacturing steel-related products. As an alternative example, the control unit 11 may purchase the certification information from the intermediary without determining whether or not the delivery date is before the date and time of the next auction. The amount of power purchased from the intermediary (in units of MWh as an example) may be the same as the shortfall with respect to the required power amount, or may exceed the shortfall.

On the other hand, if the control unit 11 determines that the delivery date is later than the date and time of the next auction or that they are on the same date, it purchases additional proof information at the next auction. After completing the purchase of the additional certification information, the control unit 11 notifies the other information processing devices to start manufacturing steel-related products. The amount of additional certification information purchased may be the same as the shortfall with respect to the required power amount, or may exceed the shortfall.

If the additional proof information cannot be purchased in the next auction (for example, if the successful bid is not successful, or if the date and time of the next auction is later than the delivery date), the control unit 11 terminal to order and purchase certificates. Alternatively, the control unit 11 may further participate in the next auction to purchase additional proof information.

An information processing method by the control unit 11 of the information processing device 1 will be described with reference to FIG.

In step S1, the control unit 11 acquires order information for steel-related products.

In step S2, the control unit 11 determines manufacturing standards and the like for steel-related products from the order information.

In step S3, the control unit 11 determines the necessary amount of electric power required to manufacture steel-related products from manufacturing standards and the like.

In step S4, the control unit 11 reads from the storage unit 13 the purchased certification information for certifying that the electric power used for manufacturing is electric power defined as non-fossil value or zero emission value. Step S4 may be performed before step S3.

In step S5, the control unit 11 determines whether or not the required power amount is within the range of the certified power amount certified by the certification information.

If No in step S5, the control unit 11 determines in step S6 whether or not the delivery date is before the date and time of the next auction.

When Yes in step S6, the control unit 11 purchases additional certification information from the intermediary in step S7.

If No in step S6, the control unit 11 participates in the next auction and determines whether additional proof information can be purchased in step S8.

When No in step S8, the control unit 11 executes step S7.

When Yes in step S8, the control unit 11 notifies other information processing devices to start manufacturing steel-related products in step S9. Also when Yes in step S5, the control unit 11 executes step S9.

[Modification]
