Life cycle oriented low carbon operation models of machinery manufacturing industry
Abstract It is urgent for machinery manufacturing industry to implement low carbon manufacturing to solve the problems of high energy consumption and high carbon emissions. Combining the theory of product life cycle, a system framework of low carbon operation models in machinery manufacturing industry is established, which consists of an objective layer, a strategy layer, a process layer and a supporting layer. In addition, four typical low carbon operation models of machinery manufacturing industry are proposed from the perspectives of low carbon product design, source control, process control and EOL (end of life) product disposal respectively. Finally, the proposed models are illustrated in a case of implementing low carbon manufacturing by a machine tool manufacturer.
