What is Infrastructure? “A civilization’s rise and fall is linked to its
ability to feed and shelter its people and to defend itself. These capabilities depend on infrastructure - the underlying, often hidden foundation of a society’s wealth and quality of life. A society that neglects its infrastructure loses the ability to transport people and food, provide clean air and water, control diseases, and conduct commerce.” NSF, ‘Civil Infrastructure Systems Research’,
1994.
What is Management?The act, manner, or practice of
managing; handling, supervision, or control: management of a crisis; management of factory workers.
The person or persons who control or direct a business or other enterprise Source: American Heritage Dictionary

Management Involves:Decision Making Issues across the (asset) life cycleUncertaintyRegulation/liabilityMultiple dimensions / stakeholders
As mentioned before: spatial/temporal, deterministic/probabilistic, project/network..
What is Infra. Mgmt.?Administrative process of creating,
planning, and maintaining our infrastructures
An integrated, inter-disciplinary process that ensures infrastructure performance over its life cycle
Life cycle is entire time from design through decommissioning

What do Mgmt Systems Do? Organize and summarize large quantities of
information Automate repetitive, lengthy, complicated
calculations Scenario analysis in technical/economic
terms Sound a bit ‘soft’ perhaps because they are
so “high level” - i.e. used by managers not engineers, technician, etc to see big picture
Current hip lingo: management “dashboard”
Apply Data Mining to Civil Infrastructure?civil infrastructure meets guidelines for
selecting potential data mining problems significant impact no good alternatives exist prior/domain knowledge effects of noisy data are mitigated sufficient data relevant attributes are being measured
