Description

Carbon traceability management system

The present invention relates to a carbon traceability management system used for manufacturing management for the industrial field.

Reducing greenhouse gas emissions is becoming increasingly important from the perspective of corporate social contribution, emission regulations, and emission limits.

From such trends, as described in [Patent Document 1], a system that provides the best mix of energy with different greenhouse gas intensity during production has been proposed. By using this system, it is said that greenhouse gas emissions due to fuel, received power, etc. used in the production process of products can be suppressed.

Also, as described in [Patent Document 2], there is a technique for managing the energy usage status in the production process in real time. By using this technology, it is said that greenhouse gas emissions due to fuel, received power, etc. used in the product production process can be suppressed.

JP 2005-25206 A JP 2007-264704 A

In many industries except materials such as pulp, iron, and synthetic rubber, greenhouse gas emissions in product manufacturing processes account for around 50% of materials and transportation.

The proportion of private power generation and business power is about 40%. In this way, private power generation and business power are certainly the main sources of emissions. However, what is optimized by the conventional technology described in [Patent Document 1] is the emissions from these private power generation and business power. Only.

For example, in the case of electricity, by procuring electricity from a provider with a low greenhouse gas emission intensity, greenhouse gas emissions generated through the manufacturing process and operations that support it can be suppressed. The percentage of 40% is not 0. Moreover, in reality, it is necessary to meet the demand for steam, heat, etc., and it is not possible to simply switch the energy supply source based on only the greenhouse gas intensity.

Excluding in-house power generation, the contribution of own industry is about 10-20% in industries such as medicinal chemistry, and about several to 10% in the assembly industry. Even with in-house power generation, it is about 10% for the assembly industry, about 15% for food and medicine, and about 25% for chemistry.

For this reason, in order to produce products, it is necessary to grasp or reduce the total greenhouse gas emissions from product production, including greenhouse gases generated by suppliers such as materials and electricity. On the other hand, a method that targets only private power generation and business power can be expected to have a great effect only in specific industries such as materials.

Further, in the conventional technology described in [Patent Document 2], what is monitored in real time is the production activity including the energy consumption in facilities such as offices, and the power reception status of business power. Combining with the technology of [Literature 1], there is a possibility that more advanced greenhouse gas emission reduction can be implemented. However, even in this case, it is not possible to contribute to grasping or reducing the remaining 50% of greenhouse gases emitted from materials and transportation.

For CO ₂ trading, etc., it is only necessary to be able to manage greenhouse gases emitted at business establishments. To manage emissions or reduce emissions by combining [Patent Document 1] and [Patent Document 2]. It can respond.

On the other hand, in order to calculate the carbon footprint, etc., [Patent Document 1], [Patent Document 2] and production management information are used to allocate greenhouse gas emissions as emissions per unit amount of each product. There is a need to. This must include contributions from procurement raw materials, etc., but the greenhouse gas emissions equivalent to 50% that are not managed as described above are based on macro information such as input-output tables and raw material usage. It will be determined.

Although greenhouse gas emissions management in this way can be realized in a closed form at each manufacturing plant, it does not reflect the company's efforts in terms of purchasing and inventory management. As a result, greenhouse gas emission reduction results are not transmitted to upstream (upstream) materials and parts companies through the supply chain. Conversely, efforts to reduce greenhouse gas emissions in the parts and materials industries do not have the effect of making transactions between companies advantageous.

In other words, greenhouse gas emissions trading requires reduction efforts by each industrial sector or individual company, and each reduction effort is made individually, and [Patent Literature 1] and [Patent Literature 2] are combined. While the method is a useful system for reducing such greenhouse gases, such a reduction effort cannot be used for business-to-business transactions and as a material to make transactions as advantageous as price.

An object of the present invention is to provide a management apparatus capable of grasping greenhouse gas emissions related to production in product units.

In order to achieve the above object, the carbon traceability management system of the present invention includes a means for recording and managing externally received power, received cold / heat quantity, in-house facility operation results, cold / heat facility operation results, material receipt / payment results, A means of managing production results, a means of calculating greenhouse gas emissions from each result, a means of allocating the calculated greenhouse gas emissions to a single unit quantity of product, and distribution to production lots Means for managing greenhouse gas emission data as specific data for lots is provided.

In addition, the means for calculating the greenhouse gas emission from each result is to calculate the greenhouse gas emission using the highest efficiency value of the equipment and the purchaser.

In addition, the means for recording and managing the payment results is to record the basic unit of greenhouse gas emissions of the received materials together with the price and delivery date.

Also, the means for recording and managing the receipt and payment results is to record the inventory period of the materials and raw materials that have been issued.

Means for calculating greenhouse gas emissions when calculating greenhouse gas emissions per unit for any lot that manufactures any product, or the calculated greenhouse gas emissions per unit of product The method of allocating to the greenhouse is based on the operating results of the individual manufacturing equipment used in the production lot, the use of cold / hot heat, the storage period of the raw materials used, the amount of raw materials used, etc. Distribute gas emissions to the product concerned, apportion greenhouse gas emissions associated with the operation of cold / hot facilities according to the use of cold / hot energy, and apportion greenhouse gas emissions generated during production and storage of raw materials used In addition, greenhouse gas emissions associated with cleaning, disposal, paperwork, etc. are apportioned in proportion to the production time of the production lot for a certain period.

According to the present invention, for an arbitrary lot for manufacturing an arbitrary product, the amount of greenhouse gas discharged to produce a unit quantity of the product, the electric power received and used or the electric power generated by private power generation, Not only greenhouse gas emissions associated with energy used directly in production activities, such as steam consumption, but also greenhouse gas emissions generated during the production of raw materials and greenhouses emitted during the preservation process You can also grasp the effect gas.

A greenhouse gas emission management device 101 for each lot for calculation is provided.

The manufacturing execution management device 103 records the usage results of the input materials and raw materials and the equipment used for each lot. For materials and raw materials, record the lot number and amount used, and for facilities, record the power used in the lot and the amount of heat and cold energy. Here, the amount of cold / hot heat is the amount and temperature in the case of hot water and cold water, and the amount, temperature, and pressure in the case of steam.

Calculate the amount of greenhouse gas emissions from utilities, materials, raw materials, and facilities that are assumed to be generated during the production of the lot.

In calculating the greenhouse gas emissions, the greenhouse gas emission equivalent data 107 of the power generation equipment used and the greenhouse gas emission data 108 of the materials and raw materials are used. Here, the greenhouse gas emission equivalent data 107 for each facility refers to the amount of greenhouse gas emissions generated per unit time or unit output in the operation state of the facility. In addition, the greenhouse gas emission data 108 from the production of materials and raw materials is used if there is greenhouse gas emission basic unit information 160 of the relevant materials and raw material lots at the time of arrival. Use to calculate.

In calculating the greenhouse gas emissions, the greenhouse gas emissions generated by the production of the related cleaning operations and waste lots may be apportioned based on the allocation policy 106.

The greenhouse gas emission management device 101 for each lot records and manages the greenhouse gas emission for each lot calculated by the above-described method in addition to the management items such as the production amount and the raw materials used for each lot.

2 to 13 will be used to explain the processing performed by the greenhouse gas emission management device 101 for each lot and the greenhouse gas emission distribution means for the intermediate product lot. FIG. 2 is a flowchart showing an example of processing executed by the greenhouse gas emission distribution means for the product and intermediate product lots, and FIG. 3 is a diagram showing an example of greenhouse gas emission equivalent data 107 for each facility. is there.

The data 401 of the utility facility 120 is an example of data for a facility whose greenhouse gas emission amount per unit time is determined in accordance with the operation state of the facility. The data 402 of the utility facility 120 is an example of data for a facility whose greenhouse gas emission rate with respect to the amount of raw material used is determined in accordance with the operation state of the facility. The data 403 of the utility facility 120 is an example of data targeted for a utility that changes the amount of greenhouse gas generated with respect to the unit amount of energy used by the provider (electric power company), such as purchased power from the electric power company. The data 404 of the utility facility 120 is an example of data targeted for utilities that can be managed appropriately by changing the distribution of greenhouse gas emissions according to the quality (pressure) of the utility used like air pressure.

FIG. 4 is an example of data indicating the operating status of each lot or each facility. The production lot data 500 records the process included in the production lot, its start time, end time, equipment used, amount of utility used, and the like. Further, the data 501 records the used material and the lot number and the amount of the raw material.

The usage history 601 of the utility equipment 120 shown in FIG. 5 is equipment usage status data that records the operating state on two proportional scales. For example, a boiler or the like records the operating state and the amount of fuel used in the operating state, and uses equivalent data in the form of data 402 of the utility facility 120 to record greenhouse gas emission equivalent data for the operating state. Is defined, it is possible to determine the amount of greenhouse gas emissions during that time period.

The usage record 701 of the utility facility 120 shown in FIG. 6 is the usage of the facility that can be recorded by a combination of a proportional scale (received power) and a nominal scale (provider) with respect to time, such as the amount of power received and the provider, such as the power receiving facility 110. It is an example of situation data.

7 is the usage status data of the facility that records the operation state on one proportional scale. For example, if the time change of the tank pressure is recorded as a record in a compressor or the like, the greenhouse gas emission amount can be obtained using the equivalent data 404. In the facility usage record 901 shown in FIG. 8, the amount of power used at each time is recorded.

In the inventory information 1001 shown in FIG. 9, the stock status of materials and raw materials is recorded. In addition to the lot number and item information of materials and raw materials, the arrival date (receipt date), the place of receipt, record the inventory amount and the greenhouse gas emission intensity. The stock quantity is updated every time a shipment is issued. Greenhouse gas emission basic unit (manufacturing basic unit) is recorded when data is obtained from the purchase source at the time of purchase of the material and raw materials. In addition, the transport unit obtained by dividing the greenhouse gas emissions associated with transport from the purchase source to the establishment using the management system of the present embodiment by the amount received at the time of arrival is added to the production unit. It may be recorded. For the greenhouse gas emissions associated with such transportation, data such as the emission equivalent 405 related to the transportation of materials is prepared in advance, and a method of calculating the amount of emissions according to the actual transportation distance can be adopted. good.

The facility energy usage record 1101 shown in FIG. 10 includes divisions that can be linked to production lots such as the warehouse facility 140 and the production site 130 in addition to divisions that do not depend directly on production lots such as the office 150. , Records energy consumption with respect to time for each category such as warehouses A and B.

FIG. 11 shows an example of greenhouse gas emission equivalent data 108 for each material and raw material. This can be created from an input-output table. This data indicates that when 1 kg of item AA is consumed, it is regarded as 0.12 kg of greenhouse gas emissions. When there is no basic unit data in the inventory information, this data is used for the greenhouse effect associated with raw material production and transportation. Estimates of gas emissions can be obtained.

FIG. 12 shows a description example of a greenhouse gas emission allocation policy 106 for cleaning and lot disposal. The description method of the allocation policy 106 depends on an algorithm for processing the allocation policy 106. For example, here, a disposal lot is a production lot of the same item that is manufactured within 60 hours in any item manufacturing process. Apportion in 1/3 increments. If three or more lots of the same item are not manufactured within the time, the greenhouse gas emissions from the waste lot remaining when the time has elapsed are Error processing such as assigning to a production lot of the same item executed is described.

In addition, it is described that only the item ITEM1 is apportioned by 1/10 of the production lot of the same item manufactured within 15 weeks. As for the cleaning operation, all the cells are equally divided into the immediately preceding and immediately following lots at a ratio of 1: 1, but the cell CELL1 is allotted to the next lot using the cells. With regard to cleaning of equipment, basically, for all equipment, all emissions are assigned to the first lot that uses the equipment, and for equipment EQIPMENT 11, the emissions are assigned to the lot using the equipment immediately before cleaning. It is described.

Such data is defined in advance, greenhouse gas emissions are allocated to production lots according to the flowchart of FIG. 2, and greenhouse gas emissions are calculated.

First, manufacturing lots that have been manufactured but have not yet been allocated for greenhouse gas emissions are extracted using information on the production lot results 501. Regarding the extracted production lot, in step 301, the used equipment and utilities, materials, and raw material lots are identified from the actual data 501 and the actual data is acquired.

While looping in step 302 for each equipment used in the lot, the loop in step 303 is rotated for each utility therein, in which, first, in step 311, for each utility used there. Acquire usage records. In step 312, the

utility operating status

601, 701, 801 for the time period is acquired. In step 313, greenhouse gas emission equivalent data 401 to 404 of the utility is acquired. In step 314, the utility uses the utility. Calculate and apportion the amount related to the lot of the greenhouse gas emissions.

In step 320, inventory information is acquired regarding the materials and raw materials used in the lot, and a loop is performed for each stock. In step 321, the presence or absence of purchase unit data is first confirmed, and the purchase source is obtained. If there is unit data from, the value is acquired in step 323, and if not, the value of greenhouse gas emission data 108 for each material and raw material is acquired in step 324.

Subsequently, in step 325 in step 320, the amount of greenhouse gas emissions associated with the manufacture and transportation of the material and raw material is calculated using the used amount of the material and raw material and the obtained basic unit. Also, in step 326, the greenhouse gas emissions due to the use of energy at the facility of the warehouse during the inventory period of the material and the raw material are prorated according to the weight ratio or heat capacity ratio of the other raw materials that use the same warehouse, and the greenhouse accompanying the storage is stored. Calculate effect gas emissions.

In step 330, if there is a track record of waste lots or cleaning operations for which emissions are not yet completed, a loop is performed for each of the waste lots or cleaning operations that have not been counted. In accordance with the allocation policy 106, in step 331, it is determined whether or not it is necessary to apportion the discharges of those lots to the lots. If apportioning is necessary, in step 332, the target waste lot or cleaning operation is performed. Calculate greenhouse gas emissions associated with the use of materials and raw materials and utility use. In step 333, the emission amount is apportioned to the lot according to the allocation policy 106, and in step 334, the emission amount value is updated.

In step 340, a loop is made for a time zone that has not yet been accounted for in the amount of emissions generated by the facility. In step 341, it is determined whether or not the time zone falls within the time zone in which the production lot was implemented. If so, in step 342, the balance is equally distributed with other production lots executed in that time zone. If not, in step 343, a certain proportion of the emission amount due to the facility in the time period is apportioned, and in step 344, the emission amount value is updated.

An example of a distribution process based on the allocation policy 106 will be described with reference to FIGS. In the initialization sequence, in step 14-101, the policy file is read and its contents are stored in the memory.

As shown in FIG. 13, in the disposal process of the discarded lot in step 332, first in step 14-201, the production item and the production period of the production lot to be allocated are acquired. In step 14-202, the element that is the manufactured item acquired in step 14-201 with the target attribute in the haiki-lot element is searched from the policy read and stored in the initialization sequence. If this does not exist, a haiki-lot element with target attribute = 'all_item' is selected in step 14-203. In step 14-204, the alloction child element of the haiki-lot element obtained in this way is acquired. In step 14-205, the bunkatsu child element is acquired. In step 14-206, the exception child element is acquired.

In step 14-207, it is determined whether the allocation child element hanni attribute = all_product acquired in step 14-204 or hanni attribute = same_product and the allocation lot item = discarded lot item. If they match, the allocation process is performed.

If it is determined in step 14-207 that it is the allocation target, the start date of the allocation target production lot is checked in step 14-208, and this is the allocation child acquired in step 14-204 from the production end date of the discarded lot. Check whether it is within the period specified by element time attribute and time_unit attribute.

If the allocation target lot is completed within the period, this is regarded as a normal allocation target, and the process proceeds to (A). If the period is exceeded, the process proceeds to (B).

In the processing of (A) within the period, in step 14-210, the rate attribute of the bunkatsu child element acquired in step 14-205 and the total discharge amount of the disposal lot (in the case of the disposal lot, depending on the utility usage and the material / raw material) Using this method, the apportionment amount for the allocation lot is determined. In step 14-211, the apportioned amount and apportioned amount of the disposal lot are updated, and in step 14-212, the apportioned amount obtained in step 14-210 is returned as the calculation result.

In the process of (B) when the time limit is exceeded, in step 14-221, the time_span_exception attribute of the exception child element acquired in step 14-206 is acquired, and in step 14-223, if time_span_exception attribute = allocate_to_first, Set the apportioned amount of waste lot to the return value. In other cases, the return value is zero in the example of FIG. 14, but other proportional methods may be used. In step 14-225, the apportioned amount of the discarded lot is updated, and in step 14-226, the return value is returned.

As shown in FIG. 14, in the cleaning lot allocation process in step 332, in step 15-101, the used equipment and manufacturing period of the allocation target manufacturing lot are first acquired. In the step 15-102, an element whose target attribute in the cleaning element is the equipment used in the cleaning lot (the equipment used in the cleaning lot is uniquely determined by the equipment to be cleaned) from the policy read and stored in the initialization sequence Search for. If not, a cleaning element having target attribute = 'all_cells' is selected in step 15-103. In step 15-104, the allocation child element of the cleaning element thus obtained is acquired, and in step 15-105, the bunkatsu child element is acquired.

In step 15-106, it is checked whether the equipment used for the production lot to be allocated includes the equipment for the cleaning lot. If it is included, in step 15-107, the hanni attribute of the allocation child element acquired in step 15-104 is checked. In the case of hanni attribute = prior_and_next_lot, the process of (A) is performed, in the case of prior_lot, the process of (B) is performed, and in the case of next_lot, the process of (C) is performed.

In the process of (A) where hanni attribute = prior_and_next_lot, first, a production lot that ended before the cleaning lot is searched, and in step 15-201, the equipment used for the cleaning lot is used, and Search for the production lot with the newest production end time. In step 15-202, it is obtained in step 15-105 how to apportion the generated amount generated in the cleaning lot to the production lot immediately before searched in step 15-201 and the production lot to be allocated. Determined using the bunkatsu child element. For example, when the rate attribute of the bunkatsu child element = x: y, the apportioning amount to the allocation target lot is determined as shown in Equation 1. In this case, the apportioning amount is determined as shown in Equation 2 for the immediately preceding production lot.

[Equation 1]
Apportioned amount to allocation target lot = discharge amount of cleaning lot x y / (x + y) (1)

[Equation 2]
Apportioned amount to the immediately preceding production lot = discharge amount of the cleaning lot x x / (x + y) (2)

When the rate attribute = product_quantity_depend, x is calculated in the same manner as in the case of x: y, where x is the product manufacturing amount (weight) of the allocation target lot and y is the product manufacturing amount (weight) of the immediately preceding manufacturing lot. When rate attribute = material_quantity_depend, x is the material and raw material usage (weight) of the allocation target lot, and y is the raw material and raw material usage (weight) of the previous production lot, as in the case of x: y described above calculate.

In step 15-203, the apportioned amount and the incomplete amount of the actual cleaning lot are updated, and the apportioning process is completed. In step 15-204, the value obtained in Equation 2 is added to the discharge amount of the previous lot, and the record is updated. In step 15-205, the value obtained in equation 1 is returned.

In the process of (B) where hanni attribute = prior_lot, the previous production lot is searched in step 15-301 as in step 15-201. In step 15-302, the discharge amount of the cleaning lot is added to the actual result of the manufacturing lot, and the actual result is updated. In step 15-303, the actual result of the cleaning lot itself is updated and the apportioning process is completed (not completed = 0), and in step 15-304, 0 is returned as the apportioning amount to the allocation target lot.

In the process of (C) where hanni attribute = next_lot, the discharge amount in the cleaning lot is recorded in step 15-401, and the result of the cleaning lot is updated in step 15-402, and the apportioning process is completed (not completed). = 0). In step 15-403, the value acquired in step 15-401 is returned as the apportioning amount to the allocation target lot.

Embodiment 2

In the first embodiment, the emission equivalents in each facility and utility are defined in advance in a table as shown in FIG. 4, and the table is directly searched from the facilities and utilities used in the production lot, and the emission amount is determined in this table. It is calculated using the value of.

In Embodiment 2 of the present invention, equipment such as boilers, power receiving equipment, private power generation equipment, and water is classified as primary power equipment, and power equipment that moves by receiving energy supply from these primary power equipment is classified as secondary power equipment. The non-powered equipment that moves in response to the supply of energy from the primary power equipment and the secondary power equipment is classified as the tertiary equipment, and the lookup table is prepared for the primary power equipment as in the first embodiment. For secondary power equipment and tertiary equipment, the amount of emissions will be allocated using the power supply relationship and calculation model.

FIG. 15 is a diagram showing a change in the output of the primary power equipment according to the present embodiment and a time change in the amount of greenhouse gas emission due to the output of the primary power equipment. In FIG. 15A, the vertical axis represents the output of the primary power facility, and the horizontal axis represents time. In FIG. 15B, the vertical axis represents greenhouse gas emissions, and the horizontal axis represents time. That is, FIG. 15 shows temporal changes in the output 1601 of the primary power equipment and the greenhouse gas emission 1602 generated along with the output 1601.

For example, in the case of electric power, since the greenhouse gas proportional to the amount of electric power is emitted from the electric power company, the output 1601 of the primary power equipment and the greenhouse gas emission amount 1602 are proportional. As shown in FIG. 15, the amount of emissions varies depending on the configuration of the power generation equipment or when the power is supplied from multiple power providers. The output 1601 of the primary power equipment and the greenhouse gas emissions 1602 may not be proportional.
