Description

Technical Field

[0001] The present invention relates to a product management system, and more particularly to a management system for calculating the manufacturing carbon emission value of a product from cradle to gate. Prior Art

[0002] As climate change becomes a global concern, all industries have taken action to reduce greenhouse gas emissions. Organizational carbon verification and product carbon footprint are key inventory measures, which refer to quantifying the carbon emissions generated by products, services or activities during their life cycle and ensuring the accuracy and transparency of the calculation through audits by third-party organizations. This process is crucial on the road to achieving sustainable development.

[0003] Among them, calculating the carbon emission value in the product manufacturing process is not only a reflection of the company's fulfillment of social responsibility, but also a necessary means to maintain competitiveness in the international market. Calculating carbon emission values ​​can enable companies to clearly understand the main sources of emissions in the manufacturing process, so as to formulate emission reduction strategies for high-emission links. For example, a factory may find that energy use is the main source of carbon emissions, so it can consider switching to green energy, improving energy efficiency, and reducing carbon footprint. In addition, many countries and regions have formulated carbon emission-related regulations requiring companies to report and reduce carbon emissions. Accurate carbon inventory reports help companies comply with regulations and avoid fines. At the same time, many international trade agreements and green certification programs also require the provision of carbon emission data, and even many investment institutions will consider the environmental, social and governance (ESG) performance of companies when making investment decisions.

[0004] More importantly, during the carbon inventory process, companies can discover potential energy and resource waste, thereby optimizing production processes and reducing costs. Therefore, the importance of carbon inventory as a core strategy for sustainable management of modern enterprises is self-evident. Therefore, how to accurately calculate the carbon emission value in the product manufacturing process so that companies can not only fulfill their social responsibilities, but also improve their market competitiveness and economic benefits, and contribute to the mitigation of global climate change is one of the problems that need to be overcome urgently.

Implementation

[0018] Referring to FIG. 1 , an embodiment of the present invention provides a management system for calculating the manufacturing carbon emission value of products from cradle to gate, wherein the product is a ratchet wrench as an example, but not limited to this. The components of the ratchet wrench include a handle for providing a hand-grip force application portion, a ratchet mechanism for controlling a one-way rotation mechanism, a socket interface for connecting sockets of different sizes, an internal spring for returning the pawl of the ratchet mechanism to its original position, and a retaining ring for locking the parts to prevent them from loosening. The management system is mainly composed of a first generation unit 10, a second generation unit 20, a supplier database 30, an in-plant processing machinery and equipment database 40, an outsourcing database 60, a carbon emission calculation unit 50, and a selection unit 70. As shown in FIG. 2 and FIG. 3, the first generation unit 10 generates a bill of materials (Bill of Materials) according to manufacturing a product 100. The raw material list 11 lists the raw material names, numbers and quantities of the raw materials required for feeding; in this embodiment, the product 100 takes a ratchet wrench as an example, but is not limited to this; and the raw material names required for feeding include but are not limited to the handle, ratchet mechanism, wrench head, internal spring and fixing ring, etc., of course, the aforementioned raw materials also have identification numbers, such as the handle numbered T1000, the ratchet mechanism numbered T2000, the wrench numbered T3000, the internal spring numbered T4000, the fixing ring numbered T5000, etc., and even lists the next-level numbers of the components of the ratchet mechanism T2000 (ratchet gear, pawl, switch lever), such as the ratchet gear numbered T2001, the pawl numbered T2002, and the switch numbered T2003. In addition, the raw material can be at least one of raw materials, materials, semi-finished products and finished products.

[0019] Referring to FIGS. 2 , 4 and 5 , the second generating unit 20 generates a bill of process (BOP) 21 according to manufacturing the product 100. The bill of process 21 lists the steps required for the factory production process and the steps required for outsourcing. For example, the handle and the wrench need to be forged and processed (in-factory processing), the ratchet mechanism needs to be turned or cut (in-factory processing), the internal spring and the fixing ring need to be quenched and tempered (outsourcing processing), and other related raw materials need to be surface treated (outsourcing processing), and assembled and tested (in-factory processing). It should be noted that the steps required for the factory production process listed may be the first in-factory processing station, the second in-factory processing station, the third in-factory processing station, the fourth in-factory processing station, etc., but are not limited thereto. Similarly, the steps required for outsourcing may be the first outsourcing processing station, the second outsourcing processing station, the third outsourcing processing station, the fourth outsourcing processing station, etc., but are not limited thereto.

[0020] Referring to FIG. 2 and FIG. 3 , the supplier database 30 is connected to the first generating unit 10, and multiple raw material input combinations are selected according to the raw material name, the corresponding number and quantity of the raw material. The supplier database 30 has a built-in raw material production carbon emission coefficient 31 for producing the raw material, and a built-in raw material transportation and distribution carbon emission coefficient 32 for transporting and distributing the raw material. In this embodiment, the raw material production carbon emission coefficient 31 is provided by the supplier, or refers to the common key component carbon footprint product category rule (PCR) database of the machinery industry, or refers to the official machinery industry carbon coefficient database; the raw material transportation and distribution carbon emission coefficient 32 is provided by a logistics manufacturer or supplier, or refers to the carbon emission coefficient database of various types of transportation vehicles.

[0021] The "carbon emission coefficient" in the raw material production carbon emission coefficient 31 and the raw material transportation and distribution carbon emission coefficient 32 referred to in the supplier database 30 refers to "the amount of carbon dioxide equivalent emitted per unit of production (or energy consumption or service volume)", and "activity data" refers to the size of production volume (or energy consumption or service volume) within a period of time, which is mainly calculated and estimated by substituting the unit items of the emission coefficient. Among them, various activity data can be automatically input through optical character recognition OCR (Optical Character Recognition) or AI-OCR, and the information sharing function can be achieved between systems through API (Application Programming Interface). Therefore, the calculation basis of the carbon emission coefficient 31 for raw material production and the carbon emission coefficient 32 for raw material transportation and distribution is per piece (CO2e / per piece), per unit weight (CO2e / kg), per unit volume (CO2e / m3), per unit hour (CO2e / hr), per piece per hour (CO2e / per piece*hr), per piece per unit distance (CO2e / per piece*km), per unit weight distance (CO2e / kg*km) or per unit volume distance (CO2e / m3*km); at the same time, the carbon emission coefficient 31 for raw material production and the carbon emission coefficient 32 for raw material transportation and distribution are updated every year according to the latest published values.

[0024] Referring to FIG. 2 and FIG. 5 , the outsourcing database 60 is connected to the second generating unit 20, and generates an outsourcing work order according to the process required for the outsourcing processing. The outsourcing work order corresponds to the process required for the outsourcing processing to select a plurality of outsourcing processing transportation tool combinations and a plurality of outsourcing processing manufacturer combinations. The outsourcing database 60 has built-in raw material outsourcing processing transportation and distribution carbon emission coefficients 61 for transporting and distributing raw materials to be outsourced, and raw material outsourcing processing process carbon emission coefficients 62 for outsourcing the raw materials; wherein, the raw material outsourcing processing transportation and distribution carbon emission coefficients 61 are provided by logistics manufacturers or outsourcing processing manufacturers, or refer to the carbon emission coefficient database of various types of transportation vehicles; the raw material outsourcing processing process carbon emission coefficients 62 are provided by outsourcing processing manufacturers, or refer to the carbon footprint product category rules (PCR) database of common key components in the machinery industry, or refer to the official machinery industry carbon emission coefficient database.

[0025] The definition, calculation basis, and update cycle of the "carbon emission coefficient" in the raw material outsourcing transportation and distribution carbon emission coefficient 61 and the raw material outsourcing process carbon emission coefficient 62 referred to in the outsourcing database 60 are the same as those contained in the supplier database 30, so they are not repeated here.

[0026] Referring to Figures 2, 6 and 7, the carbon emission calculation unit 50 is connected to the supplier database 30, the in-plant processing machinery and equipment database 40, and the outsourced processing database 60, and generates multiple manufacturing combinations of the product 100 from the cradle to the gate based on multiple raw material input combinations, multiple processing machinery and equipment production combinations, multiple outsourced processing transportation tool combinations, and multiple outsourced processing manufacturer combinations, and calculates the total carbon emission value of each manufacturing combination; in this embodiment, the total carbon emission value calculated by each manufacturing combination of the carbon emission calculation unit 50 includes a raw material production and manufacturing carbon emission value, a machinery and equipment operation production energy consumption carbon emission value, a raw material transportation and distribution carbon emission value, a raw material outsourced processing transportation and distribution carbon emission value, and a raw material outsourced processing process carbon emission value. Among them, the carbon emission value of raw material production, the carbon emission value of the energy consumption of mechanical equipment operation and the carbon emission value of the raw material outsourcing process are calculated based on the corresponding activity data multiplied by the corresponding carbon emission coefficient to calculate the corresponding carbon emission value combination; secondly, the carbon emission value of raw material transportation and distribution is calculated based on the address of the optional supplier through GOOGLE MAP, and according to different transportation and distribution vehicles, there are multiple transportation and distribution vehicle combinations, and the corresponding carbon emission value combination is calculated according to the raw material transportation and distribution carbon emission coefficient 32; the carbon emission value of raw material outsourcing transportation and distribution is calculated based on the address of the optional outsourcing manufacturer through GOOGLE MAP, and according to different transportation and distribution vehicles, there are multiple outsourcing transportation vehicle combinations, and the corresponding carbon emission value combination is calculated according to the raw material outsourcing transportation and distribution carbon emission coefficient 61.

[0028] According to Table 1 and Table 2 below, assume that the bill of materials (BOM) 11 of a product 100 includes S1*1, S2*1, S3*1 and S4*1, and two suppliers A and B can be found in the supplier database 30. Their corresponding raw material production carbon emission coefficients 31 are (S1MW)A, (S2MW)A, (S3MW)A and (S4MW)A, (S1MW)B, (S2MW)B, (S3MW)B and (S4MW)B. For the sake of simplicity, assume that the carbon emission coefficient calculation basis is per unit (CO2e / per piece); Similarly, the corresponding carbon emission coefficients 32 for raw material transportation and distribution are (S1TW)A, (S2TW)A, (S3TW)A and (S4TW)A, (S1TW)B, (S2TW)B, (S3TW)B and (S4TW)B. Assuming that the calculation basis of the carbon emission coefficient is the unit distance per piece (CO2e / per piece*km), and the activity data are the transportation distances d1 and d2 kilometers respectively, the total carbon emission coefficient of the manufacturing combination purchasing from different suppliers can be calculated as follows.

[0029]

[0030] The carbon emission value of raw material production provided by supplier A is: Σ(SUM)=[(S1MW)A]*1+[(S2MW)A]*1+[(S3MW)A]*1+[(S4MW)A]*1

[0031] The carbon emission value of raw material transportation and distribution provided by supplier A is:Σ(SUM)=[(S1TW)A]*d1+[(S2TW)A]*d1+[(S3TW)A]*d1+[(S4TW)A]*d1

[0032]

[0033] The carbon emission value of raw material production provided by supplier B is: Σ(SUM)=[(S1MW)B]*1+[(S2MW)B]*1+[(S3MW)B]*1+[(S4MW)B]*1

[0034] The carbon emission value of raw material transportation and distribution provided by supplier B is:Σ(SUM)=[(S1TW)B]*d2+[(S2TW)B]*d2+[(S3TW)B]*d2+[(S4TW)B]*d2

[0035] In conjunction with Table 3 below, assuming that the in-plant processing sequence in the bill of process sequence (BOP) 21 of a product 100 includes I1, I2, I3 and I4, for the sake of simplicity, assuming that the calculation basis of its carbon emission coefficient is per piece unit hour (CO2e / per piece*hr), and the activity data is the equipment operation time t1 to t4, the calculation of the carbon emission value of the in-plant processing is as follows.

[0036]

[0037] The carbon emission value of the energy consumption of the mechanical equipment in the factory is: Σ(SUM)=[(I1W)]*t1+[(I2W)]*t2+[(I3W)]*t3+[(I4W)]*t4

[0038] In conjunction with Table 4 and Table 5 below, it is assumed that the outsourcing order in the bill of process order (BOP) 21 of a product 100 includes O1, O2, O3 and O4, and two outsourcing manufacturers C and D can be found from the outsourcing database 60. Their corresponding raw material outsourcing process carbon emission coefficients 62 are (O1MW)C, (O2MW)C, (O3MW)C and (O4MW)C, (O1MW)D, (O2MW)D, (O3MW)D and (O4MW)D. For the sake of simplicity, it is assumed that the calculation basis of the emission coefficient is per unit (CO2e / per piece); Similarly, the corresponding raw material outsourcing transportation and distribution carbon emission coefficients 61 are (O1TW)C, (O2TW)C, (O3TW)C and (O4TW)A, (O1TW)D, (O2TW)D, (O3TW)D and (O4TW)D respectively. Assuming that the calculation basis of the emission coefficient is the unit distance per piece (CO2e / per piece*km), and the activity data are the transportation distances d3 and d4 kilometers respectively, the total carbon emission values ​​of the manufacturing combinations of different outsourcing manufacturers can be calculated as follows.

[0039]

[0040] The carbon emission value of the raw material outsourcing process of outsourcing manufacturer C is:Σ(SUM)=[(O1MW)C]*1+[(O2MW)C]*1+[(O3MW)C]*1+[(O4MW)C]*1

[0041] The carbon emission value of raw material outsourcing, transportation and distribution of outsourcing manufacturer C is: Σ(SUM)=[(O1TW)C]*d3+[(O2TW)C]*d3+[(O3TW)C]*d3+[(O4TW)C]*d3

[0042]

[0044] The carbon emission value of raw material outsourcing processing, transportation and distribution of outsourcing manufacturer D is:Σ(SUM)=[(O1TW)D]*d4+[(O2TW)D]*d4+[(O3TW)D]*d4+[(O4TW)D]*d4

[0045] Based on this, the carbon emission calculation unit 50 can calculate the total carbon emission value of the product 100 from the cradle to the gate under multiple manufacturing combinations. For example, the total carbon emission value of one of the manufacturing combinations (A supplier and C outsourcing manufacturer) is: Σ(SUM)=[(S1MW)A]*1+[(S2MW)A]*1+[(S3MW)A]*1+[(S4MW)A]*1+[(S1TW)A]*d1+[(S2TW)A]*d 1+[(S3TW)A]*d1+[(S4TW)A]*d1+[(I1W)]*t1+[(I2W)]*t2+[(I3W)]*t3+[(I4W)]*t4+[(O1MW)C]*1+[ (O2MW)C]*1+[(O3MW)C]*1+[(O4MW)C]*1+[(O1TW)C]*d3+[(O2TW)C]*d3+[(O3TW)C]*d3+[(O4TW)C]*d3

[0046] The selection unit 70 can sort out the top five suppliers with the lowest carbon emission values ​​and the top five outsourcing manufacturers with the lowest carbon emission values ​​from the total carbon emission values ​​under these multiple manufacturing combinations.

[0047] 1 and 8 , the selection unit 70 is connected to the supplier database 30 or the outsourcing database 60 and is responsible for selecting the top five suppliers with the lowest carbon emission values ​​as a reference for the source of procurement suppliers for the raw materials, or is responsible for selecting the top five outsourcing manufacturers with the lowest carbon emission values ​​as a reference for selecting outsourcing manufacturers for the raw materials.

[0048] Accordingly, the present invention uses the design of the raw material list 11 generated by the first generation unit 10 and the production process sequence list 21 generated by the second generation unit 20, in combination with the supplier database 30 selected to allocate a plurality of raw material input combinations, the raw material production carbon emission coefficient 31 of the built-in production of the raw material, the raw material transportation and distribution carbon emission coefficient 32, the factory processing machinery equipment database 40 selected to allocate a plurality of processing machinery equipment production combinations and the built-in machinery equipment operation production energy consumption carbon emission coefficient 41, the outsourced The database 60 selects and allocates a plurality of outsourced processing transportation tool combinations, a plurality of outsourced processing manufacturer combinations, a built-in transportation and distribution carbon emission coefficient 61 of the raw material outsourcing transportation and distribution of the raw materials that need to be outsourced, and a raw material outsourcing process carbon emission coefficient 62 of the raw material, so that the carbon emission calculation unit 50 can generate a plurality of manufacturing combinations of the product 100 from the cradle to the gate, and calculate the total carbon emission value of each manufacturing combination, so as to accurately calculate the carbon emission value of the product 100 during the manufacturing process.

[0049] The present invention accurately calculates the carbon emission value during the manufacturing process of the product 100, and then serves as the core basis for a comprehensive assessment of the carbon footprint, which has the following key significance for corporate environmental management and sustainable development:

[0050] First, fully understand the environmental impact. Carbon footprint is an indicator that measures the greenhouse gas emissions of a product throughout its life cycle, covering the stages of raw material acquisition, production, transportation, use and waste disposal. The product manufacturing process is usually one of the main sources of carbon emissions. The management system of the present invention can accurately calculate this part of the data, accurately reflect the impact of the manufacturing process on the environment, and provide a scientific basis for a complete carbon footprint assessment.

[0051] Second, it supports carbon emission reduction goals. The management system of the present invention can accurately calculate the carbon emission value in the manufacturing process, which can help enterprises identify high-emission links and take targeted emission reduction measures such as technology improvement, energy optimization or process reorganization. This can not only effectively reduce the carbon footprint of products, but also help enterprises achieve carbon neutrality or net zero emission goals.

[0052] Third, it complies with regulations and market demands. With the increasingly stringent global carbon emission regulations and standards (such as ISO 14067) and the increasing demand of consumers for low-carbon products, the management system of the present invention can accurately calculate the carbon emission value in the manufacturing process and become the key to entering the international market. Transparent and accurate carbon footprint reports can not only enhance the market competitiveness of enterprises, but also reduce the risks and costs caused by non-compliance.

[0053] Fourth, improve supply chain efficiency. Through the management system of the present invention, the carbon emission value of the product manufacturing process can be accurately calculated, allowing enterprises to work with supply chain partners to formulate carbon reduction strategies, such as selecting low-carbon raw materials or introducing green energy technologies. This not only reduces the carbon footprint of the product's entire life cycle, but also improves the overall efficiency and environmental image of the supply chain.

[0054] Fifth, achieve a balance between economic benefits and social responsibility. Accurately calculating carbon emissions through the management system of the present invention is not only a concrete manifestation of fulfilling corporate social responsibility, but also can bring potential economic benefits to the company. For example, reducing energy consumption and reducing costs, and obtaining policy subsidies or tax incentives through low-carbon products, further enhancing the overall competitiveness of the company.

[0055] Sixth, by selecting the top five suppliers and outsourced processing manufacturers with the lowest carbon emission values ​​through the selection unit, the optimized management of supply chain manufacturers and outsourced processing manufacturers can be more specifically achieved. More detailed optimized management can be carried out in terms of green procurement, local procurement, low-carbon transportation, route optimization and mechanical equipment resource sharing, further driving the carbon reduction path.

[0056] It is worth mentioning that the carbon emission calculation unit 50 further calculates the total carbon emission coefficient of each manufacturing combination, which includes the carbon emission coefficient 31 of the raw material production and manufacturing, the carbon emission coefficient 41 of the mechanical equipment operation and production energy consumption, the carbon emission coefficient 32 of the raw material transportation and distribution, the carbon emission coefficient 61 of the raw material outsourcing transportation and distribution, and the carbon emission coefficient 62 of the raw material outsourcing processing. When any carbon emission coefficient is lower than 5% of the total carbon emission coefficient of the product, it can be excluded from the calculation of the total carbon emission value of the product based on the effective control principle. This simplifies the process of the carbon emission calculation unit 50 calculating the total carbon emission value of the product 100 from the cradle to the gate and the system calculation load.

[0057] Taking one of the above manufacturing combinations (supplier A and outsourced processing manufacturer C) as an example, the total carbon emission coefficient is: Σ(SUM)=(S1MW)A+(S2MW)A+(S3MW)A+(S4MW)A+(S1TW)A+(S2TW)A+(S3TW)A+(S4TW)A+(I1W)+(I2W)+(I3W)+(I4W)+(O1MW)C+(O2MW)C+(O3MW)C+(O4MW)C+(O1TW)C+(O2TW)C+(O3TW)C+(O4TW)C

[0058] When any carbon emission coefficient is lower than 5% of the total carbon emission coefficient of the above-mentioned products 100, it can be excluded from the calculation of the total carbon emission value of the product based on the principle of effective control.
