Developing a System of Systems management framework for the Fukushima Daiichi Nuclear Disaster recovery

Systems are becoming more complex due to uncertainties arising from rapid global technological progress and the growing involvement and interconnectedness of the human factor. Thus new management approaches are needed in order to improve system management effectiveness and efficiency. This research addresses critical issues in management decision-making processes for complex systems, and proposes a System of Systems (SoS) management framework to assist system engineers to assess continuously a complex situation and develop systemic solutions to problems. This paper demonstrates the usefulness of an SOS management framework using modelling and simulation. A case study examines the application of the new approach in the emergency recovery management of the Fukushima Daiichi Nuclear Power Plant disaster in Japan. Based on research related to this incident and the recovery efforts following, the paper shows that the SoS approach can have benefits for complex system management, providing flexibility while at the same time retaining the ability to regulate the degree of control of the system.
