The rapid global adoption of prefabricated buildings introduces complexities and uncertainties in their supply chains, necessitating enhanced resilience to maintain competitiveness and stability. A systematic investigation was conducted on the influencing factors of prefabricated building supply chain resilience (PBSCR). A network model of influencing factors was constructed, and key factors affecting supply chain resilience were identified and quantified. It was demonstrated that the supply chain exhibits both small-world and scale-free characteristics. Nodes such as design changes, supply chain efficiency, and information sharing were revealed to play significant hub roles within the network. Quantitative and actionable pathways for improving supply chain resilience were provided. Five immune strategies were proposed and compared, and their effectiveness in suppressing the spread of influencing factors and network efficiency was evaluated through dynamic simulation. The degree centrality-based immunization strategy is found to most effectively reduce network efficiency, thereby controlling the occurrence and propagation of influencing factors. The findings provide new insights and practical strategies for managing prefabricated building supply chains, with implications for enhancing resilience in other industrial supply systems.

基于影响因素传递机制,通过系统梳理国内外装配式建筑领域文献数据库进行分析归纳与专家访谈相结合的方式,对装配式建筑供应链影响因素和传递关系进行识别。在影响因素识别方面,孙亚琪等[11]的研究中,通过文献整理和专家访谈构建了风险因素的装配式建筑供应链风险清单,并基于复杂网络理论分析了影响因素传递效应;朱蕾等[12]基于解释结构模型(interpretative structural modeling, ISM)的研究成果,从设计、制造、运输等环节提炼出15个关键影响因素的结构化层级关系,验证了信息共享和运输能力对韧性的直接影响。王红春等[13]提出的DEMATEL(decision making trial and evaluation laboratory)-ISM模型方法,将影响因素划分为根本、中间和直接层级,强调了设计变更(R11)、供应链效率(R20)等枢纽节点的核心作用。王乾坤等[14]采用扎根理论方法论,系统构建了供应链弹性评估框架。进一步从弹性资源、协同合作等维度补充了库存管理(R14)、构件冗余(R18)等关键因素,初步形成了影响因素指标体系。
