This volume outlines the technical details of a dynamic systems approach to megaproject risk analysis and simulation, based on the authors' long-term research into megaproject management, multi-criteria decision making, and system dynamics from 2010 to 2014. They offer a technical solution to overruns on cost and time in megaprojects, based on a comprehensive set of risks associated with social, technical, economic, environmental, and political issues in the megaproject environment and a dynamic systems approach called SDANP, an integrated use of tools including analytic network process (ANP) and system dynamics (SD) for risks prioritization and simulation. The model is described through a case study on the Edinburgh Tram Network project, along with a framework of qualitative risk analysis for megaprojects, megaproject risk quantification, and risk simulation.
