Description

Technical Field

[0001] This invention belongs to the field of supply chain management and carbon footprint monitoring technology, specifically relating to a method and system for collaborative management of multi-source information on supply chain carbon footprint based on a cloud manufacturing platform. Background Technology

[0002] Product carbon footprint management has become crucial for companies to fulfill their social responsibility and enhance their competitiveness. It covers carbon emission accounting throughout the entire product lifecycle, from raw material acquisition, production, transportation, and sales to use and recycling, and serves as a core basis for assessing a company's environmental impact.

[0003] However, current product carbon footprint management still faces many shortcomings and challenges: First, at the data level, there are issues of information asymmetry and lag. Inconsistent data collection standards and information barriers across supply chain companies lead to data asymmetry. Furthermore, long data update cycles prevent real-time reflection of carbon emission dynamics; for example, changes in raw material suppliers' production processes are difficult to synchronize with downstream companies in a timely manner, resulting in inaccurate carbon footprint calculations. Second, at the collaboration level, there are problems with imperfect and inefficient collaboration mechanisms. Traditional supply chain companies primarily have transactional relationships, lacking long-term and stable collaboration mechanisms. In carbon footprint management, companies are unwilling to share core data, such as energy consumption data in the production process, due to considerations of trade secrets and costs, making it difficult to conduct full-chain carbon footprint assessments. Third, at the technical level, there is a lack of a unified information platform. Data from various companies is stored in a scattered manner, lacking a unified information integration platform, making real-time data sharing and collaborative analysis impossible. For example, different companies have different carbon footprint report formats, making it difficult to integrate them into a comprehensive full-chain assessment report. Summary of the Invention

[0004] The purpose of this invention is to overcome the existing problems in product carbon footprint management at the data, collaboration, and technology levels. It provides a method and system for collaborative management of multi-source information on supply chain carbon footprint based on a cloud manufacturing platform, and constructs a product carbon footprint evaluation model based on the cloud manufacturing model. This expands the application of cloud manufacturing technology in the field of carbon footprint management and is of great significance in helping enterprises achieve precise emission reduction and enhance their competitiveness.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A collaborative management method for multi-source information on supply chain carbon footprint based on a cloud manufacturing platform includes: S1 defines the product system boundary and clarifies the various stages that need to be considered in the product lifecycle; S2 builds a product supply chain network based on product system boundaries and completes unified identity authentication on the cloud manufacturing platform; S3, based on the data interface and service management interface of the cloud manufacturing platform, collaborates with supplier companies to call the product carbon footprint life cycle assessment platform to carry out carbon footprint assessment work and realize data interaction and storage. S4, based on the cloud manufacturing platform management functions, unifies the management of product lifecycle carbon footprint calculation results and suppliers, obtains overall carbon footprint assessment, and provides data support for supply chain optimization.

[0006] A further improvement of this invention is that S1 defines the product system boundary to clarify the various stages that need to be considered in the product lifecycle, including: The product system boundary is defined as "door to door," which only covers the manufacturing stage from when raw materials enter the production organization to when finished products leave the production organization; this is applicable to carbon footprint accounting within manufacturing enterprises. Alternatively, the product system boundary can be defined as "cradle to gate," which only covers the stage from when the product is obtained from raw materials to when it leaves the production organization, excluding the use and disposal stages; this is applicable to carbon footprint assessments during the internal management of the supply chain or the product design stage. Alternatively, the product system boundary can be defined as "cradle to grave," encompassing the entire lifecycle of a product from raw material extraction to final disposal, including raw material acquisition, manufacturing, distribution, use, and waste disposal stages; this is suitable for scenarios requiring a comprehensive assessment of the product's environmental impact.

Simultaneously, data interaction and storage are carried out using cloud manufacturing platforms to further improve the efficiency and accuracy of carbon footprint management.

[0013] A further improvement of this invention lies in that, based on the cloud manufacturing platform management function, S4 uniformly manages the product lifecycle carbon footprint calculation results and suppliers, obtains the overall carbon footprint assessment, and provides data support for supply chain optimization, including: Relying on the lifecycle carbon footprint management function of the cloud manufacturing platform, it supports the integration of multi-source data, including carbon emission data, energy consumption data, material information and production process data of each link in the supply chain, thereby realizing accurate accounting and management of the carbon footprint of the product lifecycle.

[0025] In this embodiment, S1 defines the product system boundary to clarify the various stages that need to be considered in the product lifecycle, including: The product system boundary is defined as "door to door," which only covers the manufacturing stage from when raw materials enter the production organization to when finished products leave the production organization; this is applicable to carbon footprint accounting within manufacturing enterprises.

[0026] In this embodiment, S2 constructs a product supply chain network based on the product system boundary and completes unified identity authentication on the cloud manufacturing platform, including: After the system boundaries are defined, all members of the product supply chain network involved need to register on the cloud manufacturing service platform and join the supplier database to manage their product carbon footprint data in a unified manner.

[0027] In this embodiment, S3, based on the data interface and service management interface of the cloud manufacturing platform, collaborates with supplier enterprises to call the product carbon footprint lifecycle assessment platform to conduct carbon footprint assessment work, and realize data interaction and storage, including: The supplier defines the product business process flow internally; Supplier companies should establish lifecycle data inventories internally; The supplier company internally utilizes the product carbon footprint life cycle assessment cloud manufacturing platform to build a carbon footprint calculation model and conduct carbon footprint calculations; Supplier companies analyze the carbon footprint calculation results internally, conduct carbon footprint assessments, and rely on cloud manufacturing platforms for data exchange and storage.

[0028] In this embodiment, the supplier company internally defines the product business process flow, including: Suppliers at all levels define the complete business process of their products, from raw material procurement, production and processing, logistics and transportation to final delivery, based on their own business needs. This process will serve as the boundary for carbon footprint calculation and the starting point for data collection.

[0029] In this embodiment, the supplier company establishes a lifecycle data inventory, including: Suppliers at all levels are required to establish a product lifecycle data inventory, covering key data on raw materials, energy consumption, process parameters, and emission sources. This data will serve as the basis for subsequent carbon footprint calculations.

[0030] In this embodiment, the supplier company internally calls the product carbon footprint life cycle assessment cloud manufacturing platform to build a carbon footprint calculation model and conduct carbon footprint calculations, including: The construction of a carbon footprint life cycle assessment model based on a cloud manufacturing platform includes defining objectives and scope, data collection and inventory analysis, carbon footprint model establishment, and carbon footprint calculation. Clearly define the objectives and scope, including target product description, functional unit analysis, production process analysis, and system boundary definition.

[0031] In this embodiment, the supplier company analyzes the carbon footprint calculation results internally, conducts carbon footprint assessment, and relies on a cloud manufacturing platform for data interaction and storage, including: Within supplier companies, analysis of carbon footprint calculation results identifies carbon emission hotspots and develops emission reduction strategies, such as optimizing processes, selecting low-carbon materials, and improving energy structures, to reduce carbon footprints.

[0033] Example 2 The present invention provides a method for collaborative management of multi-source information on supply chain carbon footprint based on a cloud manufacturing platform, which calculates the carbon footprint of a certain model of refrigerator product throughout its entire life cycle.

[0034] This invention provides a method for collaborative management of multi-source information on supply chain carbon footprint based on a cloud manufacturing platform, comprising: Step S1: Define the product system boundary to clarify the various stages that need to be considered in the product life cycle. Define the system boundary of the refrigerator product as "cradle to grave," covering the entire life cycle of the product from raw material mining to final disposal, including stages such as raw material acquisition, manufacturing, distribution, use, and recycling.

[0035] Step S2: Based on the product system boundaries, construct a product supply chain network. Suppliers involved in all stages, including raw material acquisition, manufacturing, distribution, use, and recycling, complete unified identity authentication on the cloud manufacturing platform.

[0036] Step S3: Based on the data interface and service management interface of the cloud manufacturing platform, collaborate with supplier companies to call the product carbon footprint lifecycle assessment platform to conduct carbon footprint assessment work, and realize data interaction and storage, including: Refrigerator manufacturers and other companies define their internal product business process flows; Refrigerator manufacturers, raw material suppliers, logistics companies, and other enterprises should establish lifecycle data lists internally; Refrigerator manufacturers, raw material suppliers, logistics companies and other enterprises internally utilize the product carbon footprint life cycle assessment cloud manufacturing platform to build carbon footprint calculation models and conduct carbon footprint calculations; Supply chain members at all levels analyze the carbon footprint calculation results, conduct carbon footprint assessments, and rely on cloud manufacturing platforms for data exchange and storage.

[0037] In this embodiment, carbon emissions during the raw material acquisition stage mainly originate from the mining, processing, and transportation of raw materials. For example, the acquisition and processing of materials such as metals, plastics, and electronic components consume energy and generate greenhouse gas emissions. According to relevant standards, carbon emission calculations for this stage include both material processing and transportation processes.

[0038] Carbon emissions during the manufacturing stage primarily originate from energy consumption during the manufacturing process, such as electricity, fuel combustion, heat, direct greenhouse gases, and waste disposal. Carbon emissions at this stage are typically calculated by collecting energy consumption data from the production process. For example, carbon emissions are generated during the manufacture of refrigerator components, assembly, and packaging.

[0039] Carbon emissions during the usage phase primarily come from the electricity consumption of the refrigerator during its use. This phase typically accounts for a large proportion of the total life-cycle carbon emissions, especially with longer usage periods. According to relevant standards, carbon emissions during the usage phase are calculated based on the refrigerator's annual electricity consumption and lifespan.

[0040] Carbon emissions during the recycling phase primarily originate from the dismantling, recycling, and disposal of refrigerators. While emissions at this stage are typically small, specific figures need to be calculated based on energy consumption and waste disposal during the recycling process.

[0041] In this embodiment, the carbon footprint of this refrigerator model at each stage of its entire life cycle, including raw material acquisition, manufacturing, distribution, use, and recycling, was statistically analyzed, and the results are shown in Table 1 below.

[0042]

[0043] Based on the above calculations, the total carbon footprint of a certain model of refrigerator over its entire lifecycle is 2488.483 kg. Of this, the carbon footprint during the raw material acquisition stage is 168.524 kg, accounting for 6.77% of the total; the carbon footprint during the product manufacturing stage is 42.965 kg, accounting for 1.73%; and the carbon footprint during the transportation stage is 5.372 kg, accounting for 0.22%. Assuming a product lifespan of 10 years, the carbon footprint during the usage stage is 2268.355 kg, accounting for 91.15% of the total; and the carbon footprint during the recycling stage is 3.267 kg, accounting for 0.13%. The order of carbon footprint across stages is: usage stage > raw material acquisition stage > product manufacturing stage > transportation stage > recycling stage. Figure 5 This is a graph showing the carbon footprint percentages of this refrigerator model across its lifecycle stages.

[0044] This indicates that the usage phase is the stage with the largest carbon emissions in the product's entire life cycle, accounting for 91.15% of the total emissions, demonstrating its dominant role in the product's life cycle. Therefore, when exploring carbon reduction strategies, the focus should be on controlling carbon emissions during the usage phase to achieve more effective carbon reduction targets. Meanwhile, the carbon emissions during the recycling phase are extremely low (only 0.13%), reflecting significant room for optimization in product recycling and reuse, and also demonstrating society's gradual practice and promotion of environmental protection concepts.

[0045] Step S4: Based on the cloud manufacturing platform's management functions, uniformly manage the product lifecycle carbon footprint calculation results and suppliers, obtain the overall carbon footprint assessment, and provide data support for supply chain optimization.

[0046] In this embodiment, the cloud manufacturing platform can integrate carbon emission data from all stages of refrigerator product lifecycle, including raw material acquisition, production, distribution, use, and recycling, enabling unified management of the product's carbon footprint. Through the platform's database and data analysis functions, enterprises can obtain real-time calculation results of their product's carbon footprint, facilitating quantitative analysis and optimization of the carbon footprint.

[0047] Meanwhile, the cloud manufacturing platform supports the management of refrigerator supplier information, including supplier BOM information, production energy consumption, and transportation data, which helps enterprises achieve transparent management of the supply chain. Through the platform's collaborative functions, enterprises can share data with suppliers, improving the efficiency and transparency of supply chain collaboration.

[0048] Example 3 like Figure 6 As shown, the multi-source information collaborative management system for supply chain carbon footprint based on a cloud manufacturing platform provided by this invention includes: The product system boundary definition unit defines the product system boundary and clarifies the various stages that need to be considered in the product lifecycle. The network construction and identity authentication unit builds a product supply chain network based on the product system boundary and completes unified identity authentication on the cloud manufacturing platform; The carbon footprint assessment unit, based on the data interface and service management interface of the cloud manufacturing platform, collaborates with supplier companies to call the product carbon footprint lifecycle assessment platform to carry out carbon footprint assessment work and realize data interaction and storage. The carbon footprint assessment optimization unit, based on the cloud manufacturing platform's management functions, uniformly manages the product lifecycle carbon footprint calculation results and suppliers, obtains the overall carbon footprint assessment, and provides data support for supply chain optimization.
