Life Cycle Assessment Of Product Carbon Footprint Under Cloud Manufacturing Model

As the global warming trend has intensified,the concept of environmental protection has gradually gained popularity.In order to resolve the contradiction between economy and resources,greenhouse gas emissions have gradually become one of the hotspots of common concern of the international community.How to accurately evaluate the carbon footprint has become an important issue at present,and in many carbon footprint assessment methods,life cycle assessment is widely used as a carbon footprint evaluation method.At the same time,cloud manufacturing,as a new manufacturing model,shares secure and reliable product information and services in real time through the cloud manufacturing service platform to achieve efficient use of resources.It not only provides a platform for product manufacturing services and supply chain collaboration,but also provides new ideas for product carbon footprint management and low carbon development.This thesis is proposed in this context.From the perspective of cloud manufacturing,and deeply studies the calculation and evaluation of product carbon footprint in the supply chain.Specific research content includes:(1)The structure and characteristics of the supply chain under the cloud manufacturing model are analyzed,as well as the opportunities and challenges brought by cloud manufacturing to the carbon footprint assessment of supply chain products.Through the cloud manufacturing resource service combination and optimization,the optimal configuration of cloud manufacturing service platform information resources is realized,and the product carbon footprint information integrated management scheme based on cloud manufacturing service platform is proposed,and the product carbon footprint evaluation under cloud manufacturing mode.(2)According to the traditional life cycle assessment method and cloud manufacturing theory,the carbon footprint life cycle evaluation model of home appliance products under cloud manufacturing mode is proposed.Firstly,the target product and its system boundary are determined,and then the corresponding data is collected according to its boundary,and the carbon footprint calculation system based on cloud manufacturing platform is used for calculation and analysis.(3)Taking the refrigerator product of H company as an example,based on the carbon footprint life cycle evaluation model of household appliances under the cloud manufacturing mode,a case study was carried out.A more accurate calculation of the carbon footprint of X-type refrigerator product during its entire life cycle.(4)Through the life cycle assessment of the carbon footprint of H company’s refrigerator products,the low-carbon measures of refrigerator products were discussed from the aspects of electric energy,transportation and recycling.In terms of electrical energy,wind power generation is the safest,cleanest,and lowest carbon power generation method compared to thermal power generation,which is 53.13% lower than thermal power generation.In terms of transportation,the carbon footprint of railway transportation is the least,which is 4.7% of road transportation.In the recycling phase,three ways to improve product recycling efficiency are proposed.The research in this thesis provides a theoretical basis for corporate environmental governance practices,is conducive to the low carbon and sustainable development of manufacturing enterprises and supply chains,and is of great significance to promote the improvement of ecological environment.
