Abstract: With the increasing enhancement of people's consciousness of sustainable development,the traditional manufacturing industry is deeply remolding and transforming into green,intelligent and service-oriented.Manufacturing enterprises had successively applied various advanced information technology (cloud computing,CPS,IoT,simulation modeling) to solve various problems in sustainable manufacturing.With the integration of physical world and virtual world centered on green features,a new paradigm of digital twin driven green manufacturing was proposed,and a five-dimensional digital twin model with green features was established to reconstruct the relationship between physical entities,virtual twins,data,interactive interfaces,services and the green characteristics of elements in green manufacturing process.Then,the application of green material selection,green disassembly,green recycling,green remanufacturing and reverse supply chain under the five-dimensional digital twin model were analyzed.The energy consumption management platform of product life cycle based on energy consumption feature extraction was validated.

Key words: digital twin, green manufacturing, five-dimensional digital twin model, product life cycle, manufacturing industry

摘要： 随着人们可持续发展意识的增强,传统制造业正深刻重塑并向绿色化、智能化、服务化转型。制造企业相继运用各种先进信息化技术(云计算、信息物理系统、物联网、仿真建模)来解决可持续制造中的各类问题,由此提出数字孪生驱动的绿色制造新模式,围绕以绿色特征为中心的物理世界与虚拟世界的交互与融合,建立了包含绿色特征的五维数字孪生模型,以重塑绿色制造过程中物理实体、虚拟孪生体、数据、交互接口、服务五维要素之间的关系及要素的绿色特性。分析了五维数字孪生模型下绿色材料选择、绿色拆解、绿色回收、绿色再制造及逆向供应链领域的相关应用,最后以基于绿色特征提取的产品生命周期能耗管理平台验证了提出的五维数字孪生体驱动的产品生命周期绿色制造新模式。
