Infrastructure Resilience

The concept of 'network resiliance' refers to the capacity of a network to resist damage "whether we are talking about our failing infrastructures because of the current economic crisis, or we are worrying about targeted infrastructure when discussing cyber-war and terror attacks." But many human-made networks are designed for efficiency, not resiliance. Resiliance requires redundancy, which runs counter to efficiency. In fact, in systems both natured and nurtured, we see in the best systems a balance between efficiency and redundancy. Too often (in my mind) calculations of best value take into account only efficiency, without accounting for the need to build in redundancy.
