This work aims at conducting a comprehensive investigation of network structures of humanitarian organisations and elaborating the resulting influences on their logistical activities. This is the first work that connects the organisational structures of humanitarian organisations with logistical aspects. Organisational components and their relationships, as well as influencing factors, are identified, and essential scientific and practical implications derived. For this purpose, a multiple case study based on ten humanitarian non-governmental organisations (NGOs) was conducted. Interviews and surveys, as well as publicly available and internal documents of the organisations, served as research material. In this case study, four components of networks were identified, and their interrelationships described. The logistical influences were consequently analysed. It is shown that the dimensions of formalisation, centralisation, and standardisation in humanitarian organisational networks have an impact on logistics activities. This paper further provides theoretical and practical implications.
