社会制造被概念化为一种新型的网络化制造模式，支持社会化制造资源（SMR）的组织，以满足在共同创建开放式架构产品时对人群智能的个性化需求的增长。每一个利益相关者在这类产品生产中的高度参与，对社会、网络和物理空间之间的充分合作提出了更高的要求。然而，在一个分散的社会制造网络，管理的SMR遇到了一些现实生活中的挑战，在其分布和异构的功能。因此，本文提出了一个基于区块链的数字孪生协作平台（BcDTCP），作为解决这些挑战的综合解决方案。提出了一种混合领域驱动的设计方法来设计和实现业务知识驱动的系统。为了解决SMR的异构性，设计了一种无处不在的对象结构，以灵活地调整数字孪生的功能。引入区块链来构建点对点网络，以分散的方式组织SMR。此外，还采用了一种基于时间着色Petri网的工作流，将协作逻辑公式化为在区块链上执行的智能合约。最后，进行了示范性的案例研究，以验证和评估所提出的BcDTCP下的3D打印场景。
Social manufacturing is conceptualised as a new type of networked manufacturing paradigm that supports the organisation of socialised manufacturing resources (SMRs) to satisfy the growth of personalised demands on crowd intelligence in a timely manner when co-creating open architecture products. The high participation of each stakeholder in this type of product production places a higher requirement on sufficient collaboration among social, cyber and physical spaces. However, under a decentralised social manufacturing network, the management of SMRs has encountered some real-life challenges in terms of their distributed and heterogeneous features. Hence, this paper proposes a blockchain-enabled digital twin collaboration platform (BcDTCP) as an integrated solution to address these challenges. A hybrid domain-driven design method is presented to design and implement business-knowledge driven systems. To address the heterogeneity of SMRs, a ubiquitous object structure is designed to flexibly adjust the functionality of the digital twin. Blockchain is introduced to construct a peer-to-peer network to organise the SMRs in a decentralised manner. Additionally, a timed coloured Petri net-based workflow is adopted to formulise the collaboration logic into a smart contract executed on the blockchain. Finally, a demonstrative case study is conducted to verify and evaluate the proposed BcDTCP under a 3D printing scenario.
