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

The Bottom Line:

aka Good Advice about Infrastructure Management

(and Life in General)
