Radar Space-Time Module and Scoring

1. Radar Space-Time Module and Scoring Ulas Bardak (Carnegie Mellon)

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

3. IET Scoring Tree • Each child has a weight • Score for node with n children: • Bottom-up score propagation RADAR

4. Overall Score Overall Score 0.25 0.15 0.6 Background Tasks Schedule Notification Reading and answering emails Quality of the conference schedule Web-page updates and briefings RADAR

5. 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 RADAR

6. 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 RADAR

10. Overall Comparison Overall score: • Schedule is 60% • Background tasks are 25% • Notifications are 15% Schedule score, 32 leaves: • 6 require no modification • 9 require minimal modifications • 2 require significant modifications • 15 require massive changes to thecurrent system RADAR

13. 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 RADAR

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 RADAR
