Conflicts since the end of the Cold War have seen military and civilian assets deployed side by side as part of an overall UN mandated solution. In order to visually present the integrated nature of humanitarian supply chains ‘Structured Analysis and Design Technique’ (SADT) has been used. SADT was chosen as it provides a robust structured method to model hierarchical systems and for this research it provides an opportunity to define and analyse the coordination and co-operation in terms of the humanitarian supply chain process, humanitarian supply chain activities and the actors involved. This research demonstrates that the visualisation facility that SADT provides not only helps in understanding the interrelationships between the actors and stakeholders involved in a humanitarian supply chain but also to some extent explains how a more effective co-ordination of humanitarian operations by military and civilian organisations involved in a complex emergency can be achieved.
