• Overview of IET Scoring
• Mapping from IET Scoringto Space-Time Module
• Approach and effort estimate

IET Scoring Tree

• Each child has a weight
• Score for node with n children
• Bottom-up score propagation

Schedule Score

• ScheduleQuality is weighted sum of leaves
• DollarCost is vendor fees
• DollarFloor is estimated minimal cost
• RoomQueryCost is number of requested rooms
• RoomQueryFloor is the estimated minimal number

Schedule Quality

• We compute the schedule quality as a
• weighted sum of leaf scores. We divide
• the leaves into four categories
• no changes
• minor changes
• significant changes
• massive changes

Summary

• Half of the leaves in the schedule-quality
  evaluation require extensive changes to
  Space-Time Module
• We tentatively estimate that this work may
  require two to three months of full-time
  programming
• Evaluation of the background tasks and
  notifications is based on the information
  unavailable to Space-Time Module, and should
  probably be outside the module

14
Summary

• Implementing IET Scoring in Space-Time Module may
  take as much work as implementing it from scratch
• On the positive side, it may help with future
  extensions to Space-Time Module
