Overview

• Scenario Emergency manager needs to determine
  short term shelter needs and longer term
  temporary housing after Magnitude 7.9 Earthquake
  in Shelby County Tennessee.
• Load Housing data and Freeways from Remote or
  Local Repositories
• Start from Dislocation Analysis and work
  backwards to create required inputs
• Damage Analysis with hazard uncertainty option
• Style View
• Result table with result columns highlighted
• Start from Dislocation analysis and work forward
  to Short Term Shelter Needs
• Highlight areas of large dislocation results
• Generate Shelter Supply requirements and display
  in report
• Run Temporary housing and report on housing
  assignments for displaced families

Overview

• Decision makers of Shelby County need to exercise
  1,500,000 budget to retrofit highway bridges for
  preparing an earthquake (magnitude 7.9). They
  have six retrofit methods to be implemented and
  want to minimize the societal cost (which is
  measured via total system travel time (TSTT)).
  As a result, they need to know which bridge needs
  to be retrofitted with which method while
  minimizing TSTT under budget constraint.
