A system of systems framework for the evaluation of critical infrastructure - the case of Changi international airport.

Abstract

Critical Urban Infrastructures are always a crucial concern to any governments and their decision makers. Infrastructures based on the current demographic trend, future cities will provide residence for almost 70% of total global population in a few decades. However, we stand at a crossroad, that cities must change radically to achieve long-term sustainability and survivability. Shortage of energy, food and water resources, inadequate public transportation systems and other basic infrastructures, will constrain the potentials and diminish the quality of life in future cities. Moreover, natural disasters such as cyclone, earthquake and flooding and man-made disasters resulting from terrorism and negligence are emerging threats to the integrity of these critical urban infrastructures.
