Dependency and Structure Modelling (DSM) techniques support the management of complexity by focusing attention on the elements of a complex system and how they are related to each other. The DSM perspective can assist in understanding, designing and optimising complex systems – including products, processes and organisations. This volume comprises peer-reviewed papers representing state-of-the-art in DSM research and applications. The papers were presented at the 17th International DSM Conference held in November 2015 in 2015 in Fort Worth (Texas, USA).
