Even though infrastructure dependencies and interdependencies are often overlooked, they significantly impact infrastructure performance. The existing dependency and interdependency classifications are fragmented and lack a comprehensive, universally accepted system. Therefore, this study aims to develop a novel and precise categorisation of infrastructure dependencies and interdependencies. A systematic literature review was conducted, filtering 58 relevant articles from a total of 570 for thematic analysis. The findings reveal that no distinct classifications for infrastructure dependencies are available and interdependency classifications are often used instead, overlooking the specific “direction” of dependencies. While this practice may not harm dependencies under normal conditions, such misinterpretation can undermine resilience and performance of infrastructures during emergencies and disasters. Furthermore, the study developed a novel and precise classification system for interdependencies and suggests how further refinements into more specific categories can be made.
