基于区块链技术的异构社群制造资源数字孪生封装共享方法

针对社群化制造中各类闲散的、智能化程度良莠不齐的社会化生产资源在制造协作互联中存在的问题，本项目提出构建资源的数字孪生对象，以数字孪生对象为纽带实现物理-信息-社交空间多维协同的设想。然而在社群化制造资源的异构性为其数字孪生对象的构建带来了新的挑战。本项目深入分析了社群制造资源的多源异构特性在数字孪生模型层面和服务化封装层面的影响。在模型层面，分别从数字孪生本体的角度研究多领域异构数字孪生模型融合方法，从数字孪生数据的角度研究多模态数据的异构融合方法。在服务化封装层面，分别从封装框架、封装架构和封装技术三个维度研究模型在异构部署环境下的可自主重构封装方法。最后，考虑社群本身具备知识共享的优势以及社群弱中心化、去中心化的组织结构，设计基于区块链技术的去中心化数字孪生封装共享机制，解决数字孪生类知识密集型软件著作在社群环境下的著作保护和共享权益问题，促进数字孪生技术在社群制造中的可复制性应用。

The diversified social manufacturing resources (SMRs) with different intelligence levels have hindered the efficient collaboration and interconnection during the process of production execution. Hence, this project proposes to construct the digital twins for SMRs, and takes digital twin as the major link to realize the multi-dimensional collaboration among physical, cyber and social space. However, the heterogeneity of SMRs brings more challenges to the construction of their digital twins. Therefore, this project deeply analyzes the influences of multi-source heterogeneous characteristics of SMRs on the aspects of digital twin modeling and servitization encapsulation. For digital twin modeling, this project focuses on the multi-domain fusion method for the heterogeneity in digital twin ontology. Then, from the perspective of heterogeneous data, a fusion method for multi-modal data will be explored. As for servitization encapsulation of digital twin, this project proposes an autonomous reconfigurable encapsulation method for the heterogenous runtimes in social manufacturing from the view of encapsulation framework, architecture and technique. Finally, as the social community has the advantage of knowledge sharing and its organization structure tends to weak centralization and decentralization, a decentralized digital twin sharing mechanism is designed based on blockchain technology. It aims to address the problems of knowledge-intensive copyright (e.g. digital twin) protection and shard equity under social manufacturing environment, which facilitate the sharing of digital twin for reproducible applications.
