Industrialized construction (IC), encompassing off-site construction (OSC) and on-site industrialized construction (OIC), is pivotal to promoting sustainability in the construction sector. However, existing research in the construction industry has focused predominantly on the advantages of OSC, while overlooking the value of OIC to the broader industrialization of the building sector. In this paper, a systematic evaluation is conducted of key OIC technologies' contributions to industrialization goals (IGs). Through case studies and literature analysis, 8 critical OIC technologies and 7 IGs are identified. An advanced decision-making framework, integrating the decision-making trial and evaluation laboratory (DEMATEL) to analyze IGs interactions and weights, hesitant fuzzy numbers to address evaluation uncertainty, and prospect theory to incorporate psychological preferences, is employed to systematically rank the contributions of OIC technologies. Results indicate: (1) the importance ranking of IGs is: labor saving, efficiency improvement, costs reduction, quality enhancement, resource conservation, safety assurance, and pollution reduction. (2) The ranking of OIC technologies based on their contributions to IGs is: Interspersed construction, High-precision lightweight formwork, Centralized steel bar processing and distribution, Digitization and intelligent assistive technologies, Intelligent self-climbing scaffolds, Ready-mixed concrete and pumping, Full cast-in-situ exterior walls, and Floor water interception systems. This study empirically quantifies the contribution of each OIC technology to key IGs and defines an upgrading direction that enables traditional construction practices toward on-site industrialization, thereby reducing the sector's path dependence on OSC. In addition, it establishes an integrated evaluation framework that helps decision-makers identify and prioritise the most suitable OIC technologies.

评估现场工业化建筑技术对工业化目标的贡献

工业化建筑 （IC），包括场外施工 （OSC） 和现场工业化建筑 （OIC），对于促进建筑行业的可持续发展至关重要。然而，建筑行业的现有研究主要集中在 OSC 的优势上，而忽视了 OIC 对建筑行业更广泛工业化的价值。本文对 OIC 关键技术对工业化目标 （IG） 的贡献进行了系统评估。通过案例研究和文献分析，确定了 8 项关键的 OIC 技术和 7 项 IG。采用先进的决策框架，整合决策试验和评估实验室 （DEMATEL） 来分析 IGs 的相互作用和权重，整合了犹豫不决的模糊数字来解决评估不确定性，并整合了结合心理偏好的前景理论，用于系统地对 OIC 技术的贡献进行排名。结果表明：（1） IG 的重要性排序为：节省劳动力、提高效率、降低成本、提高质量、节约资源、保证安全、减少污染。（2） 基于对 IG 的贡献，OIC 技术排名为：散布施工、高精度轻模板、钢筋集中加工和分配、数字化和智能辅助技术、智能自爬脚手架、预拌混凝土和泵送、全现浇外墙和地板截水系统。 本研究实证量化了每种 OIC 技术对关键 IG 的贡献，并定义了一个升级方向，使传统建筑实践能够转向现场工业化，从而减少该行业对 OSC 的路径依赖。此外，它还建立了一个综合评估框架，帮助决策者确定最合适的 OIC 技术并确定其优先级。
