Abstract The information generated from a nonconformance can be used to determine the party responsible for ensuring that quality standards are assured. However, in the construction industry, the absence of a uniform and transparent system for managing quality information undermines the assurance process and may lead to disputes among stakeholders. In addressing this issue, we develop a blockchain-based framework for managing quality information, referred to as “Product Organization Process (POP) qualityChain”. A Hyperledger-Fabric-based architecture and a series of blockchain solutions (e.g., a POP-model-based quality information structure, a consensus mechanism, smart contracts for processing quality information, authorization sequences, and execution processes) are covered. Finally, we build a prototype system and use a case study to validate our framework. Results show that the proposed framework can decentralize the management of quality information, thereby achieving consistent and secure quality information management. Future work could seek more evidence from practice to further validate our framework.

使用区块链进行施工质量信息管理

摘要 不符合项产生的信息可用于确定负责确保质量标准的一方。然而,在建筑行业,缺乏统一和透明的质量信息管理系统会破坏保证过程,并可能导致利益相关者之间的纠纷。为了解决这个问题,我们开发了一个基于区块链的质量信息管理框架,称为“产品组织流程 (POP) qualityChain”。涵盖了基于 Hyperledger-Fabric 的架构和一系列区块链解决方案(例如,基于 POP 模型的质量信息结构、共识机制、处理质量信息的智能合约、授权序列和执行过程)。最后,我们构建了一个原型系统并使用案例研究来验证我们的框架。结果表明,所提出的框架可以分散质量信息的管理,从而实现一致和安全的质量信息管理。未来的工作可以从实践中寻求更多证据,以进一步验证我们的框架。
