To improve the functionality of heritage buildings, modern facility management (FM) practices have been increasingly adopted in heritage building maintenance management (HBMM). To achieve effective FM operations in HBMM, it is essential to identify the critical success factors (CSFs) and understand their relationships. Since this is an underexplored area, a study was initiated to establish a hierarchical structure of the CSFs and ascertain their influence on each other. Under the study, HBMM experts were invited to assess the interrelationships of the CSFs through an online survey. Then, an interpretative structural modeling (ISM) technique was used to establish the envisaged hierarchical structure. Finally, Matrice d'Impacts Croisés Multiplication Appliqués à un Classement (MICMAC) analysis was used to classify the CSFs into four clusters based on their dependence and driving powers. From the ISM analysis, a hierarchical structure composed of seven levels was resulted, with the CSFs at the bottom of the hierarchy belonging to the independent categories with strong driving power but weak dependence power. Achieving these CSFs, which will drive the realization of other CSFs, warrant particular attention from HBMM practitioners. With an integrated ISM – MICMAC model developed, this study contributes to knowledge by establishing the hierarchy and interactions among the CSFs. The CSFs classification also serves as a guide for HBMM practitioners in understanding the operational dynamics of the CSFs and prioritizing their importance. The approach of this study, which is novel in the HBMM research domain, also forms a fertile foundation for future studies in this field.

为了提高文物建筑的功能，现代设施管理（FM）实践越来越多地应用于文物建筑维护管理（HBMM）中。为了在 HBMM 中实现有效的 FM 操作，必须确定关键成功因素 (CSF) 并了解它们之间的关系。由于这是一个探索不足的领域，因此启动了一项研究，以建立 CSF 的层次结构并确定它们之间的相互影响。在这项研究中，HBMM 专家受邀通过在线调查评估 CSF 的相互关系。然后，使用解释结构建模 (ISM) 技术来建立设想的层次结构。最后，Matrice d' Impacts Croisés Multiplication Appliqués à un Classement (MICMAC) 分析用于根据 CSF 的依赖性和驱动力将其分为四个集群。从ISM分析得出一个由七个层次组成的层次结构，层次结构底部的CSF属于驱动力强但依赖力弱的独立类别。实现这些 CSF 将推动其他 CSF 的实现，值得 HBMM 从业者特别关注。通过开发集成的 ISM - MICMAC 模型，本研究通过建立 CSF 之间的层次结构和相互作用来促进知识的发展。CSF 分类还可以作为 HBMM 从业者了解 CSF 的运营动态并确定其重要性优先级的指南。这项研究的方法，
