2. Infrastructure Management Review H. Scott Matthews April 30, 2003

3. Announcements / Agenda  HW 4 Brief Review today  HW 5, Final ‘Optional’, due next week  SABIS Brief Demo  Competing/replacing infrastructure  Course Review

4. Recap of Last Lecture(s)  VoIP as potential replacement technology / infrastructure for telephony  Issues associated with infrastructure / technology transition  What are other general, big picture issues?

5. Course Review in < 10 slides

6. 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.

7. 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 (00)

8. Management Involves:  Decision Making  Issues across the (asset) life cycle  Uncertainty  Regulation/liability  Multiple dimensions / stakeholders  As mentioned before: spatial/temporal, deterministic/probabilistic, project/network..

9. 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

10. Life Cycle Cost Influences Decreasing Influence Increasing Expenditure 100% 50 % 0%0% Planning Design Construction Maintenance Disposal Time Cum. Cost Level of Influence

11. Approaches to Performance  Condition Assessment  Condition Indices  Reliability Theory  Multi-dimensional Measures

12. “Failure”  Failure as not meeting expectations  Happens when P(t) < P F  Need to maintain performance level  Expectations increase over time P PFPF TDTD

13. Existing Interdependency Diagrams Production, Cooling, Emissions Reduction Water for Power for Compressors, Storage, Control Systems Fuel for Generators Power for Pump and Lift Stations, Control Systems Power for Switches Water for Cooling, Emissions Reduction Heat Power for Pumping Stations, Storage, Control Systems Fuel for Generators, Lubricants SCADA, Communications SCADA, Communications SCADA, Communications SCADA, Communications Fuels, Lubricants SCADA, Communications Water for Cooling Fuel Transport, Shipping Fuel Transport, Shipping Shipping Power for Signaling, Switches Fuel for Generators Water for Production, Cooling, Emissions Reduction Water Transpor- tation Oil Telecom Natural Gas Electric Power

14. 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”

15. 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

16. The Bottom Line: aka Good Advice about Infrastructure Management (and Life in General)  Nothing Lasts Forever..  Plan Accordingly
