衡量区块链和智能合约对建筑供应链可见性的影响

Measuring the Impact of Blockchain and Smart Contract on Construction Supply Chain Visibility

Stanford University(斯坦福大学)

Hesam Hamledari, Martin Fischer

摘要:

这项工作评估了区块链和智能合约对建筑供应链的可见性和支付环境(现金流和产品流的交叉点)的影响。它使用比较实证实验(Charrette测试方法)来比较商业建设项目中实践状态和区块链支持的支付系统的可见性。在四个粒度级别上进行了比较。调查结果有两个方面:1)与数字实践解决方案相比,区块链将信息完整性和信息准确性分别平均提高了216%和261%。对于具有更高产品,交易和时间粒度的查询,这些改进更为明显; 2)区块链解决方案在面对更高粒度时是强大的,而传统解决方案在信息的完整性和准确性方面分别下降了50%和66.7%。本文最后讨论的机制,有助于可见性和技术采用的基础上的业务目标。

英文摘要:

This work assesses the impact of blockchain and smart contract on the visibility of construction supply chain and in the context of payments (intersection of cash and product flows). It uses comparative empirical experiments (Charrette Test Method) to draw comparisons between the visibility of state-of-practice and blockchain-enabled payment systems in a commercial construction project. Comparisons were drawn across four levels of granularity. The findings are twofold: 1) blockchain improved information completeness and information accuracy respectively by an average 216% and 261% compared with the digital state-of-practice solution. The improvements were significantly more pronounced for inquiries that had higher product, trade, and temporal granularity; 2) blockchain-enabled solution was robust in the face of increased granularity, while the conventional solution experienced 50% and 66.7% decline respectively in completeness and accuracy of information. The paper concludes with a discussion of mechanisms contributing to visibility and technology adoption based on business objectives.
