基于区块链的装配式建筑供应链风险因素研究

Research on Risk Factors of Prefabricated Building Supply Chain Based on Blockchain

针对传统装配式建筑供应链中存在的信息传递失真等问题,文章首先探讨了将区块链技术应用于传统装配式建筑供应链的优势,构建了基于区块链的装配式建筑供应链模型,并根据该模型对供应链中可能存在的风险因素进行了识别、归纳。其次,运用集成DEMATEL-ISM法对归纳出的各风险因素的影响关系分析得出:区块链背景下的装配式建筑供应链风险因素系统可分为5层3阶,进而建立了风险因素系统的多层递阶结构模型。最后,针对区块链技术如何保障装配式建筑供应链稳定运行提出对策建议,为实现装配式建筑供应链进一步发展提供思路。

Aiming at the problems of information transmission distortion in the prefabricated building supply and combining with the blockchain-based prefabricated building supply chain model to identify possible risk factors,the prefabricated building supply chain was optimized with blockchain technology.By using the integrated DEMATEL-ISM method to study the importance and attributes of each risk factor,a multi-layer hierarchical structure model of the risk factor system was built.The results show that the prefabricated building supply chain risk factor system under the blockchain background can be divided into five layers and three levels.On this basis,various risk factors are analyzed,and countermeasures and suggestions are put forward for the stable operation of the prefabricated building supply chain with blockchain technology,which provides solutions for further developing the prefabricated building supply chain.
