VEDAViz for ETSAP partners

1. Modeling for insights
not numbers

2. What we do, normally
• Judiciously select a handful of combinations of various factors and run
those as scenarios. Then, we use these few points of reference to
interpolate/extrapolate to cover a large solution space to draw overall
conclusions.

3. What we can do, easily
• Significantly larger combinations offer two advantages:
• They improve the quality of insights as you can identify the tipping points and
not just the different disjoint configurations.
• This large set of solutions can be made available to policy-
makers/stakeholders/domain experts as a kind of “expert system”, which they
can interrogate meaningfully even without having deep knowledge of the
model.

13. What is VEDAViz?
• A powerful and intuitive web tool for constructing and sharing views
of model results.
• Specifically designed for three distinct uses:
• Individual analysis
• Collaborative analysis
• Dissemination

14. What makes is special?
• VEDAViz makes model results truly accessible to analysts and
stakeholders at different technical levels to explore and interpret
results, pose questions, and share insights.
• It can convert a model into an expert system that can promote and
support logical discussion among policy makers, stakeholders and
modelers.

15. Basic operations
• Filter
• allows filtering of multiple elements from each of the
following dimensions: Scenario, Variable, Model, Region
and Year. Can define sets of elements often selected
together.
• Configure
• Any dimension can be: put on x-axis, summed over, used
for small multiples or put on separate tabs
• Render
• Several predefined chart types, or even in tabular form
(pivot table), which can be downloaded to Excel

16. VEDAViz uses powerful, flexible graphics to
facilitate analysis and communication

17. All this takes three things
• Create clusters of scenarios
• Run all these scenarios
• Visualize a large number of scenarios in an intuitive way

18. Dense scenario experiments
• More points of reference
• Possibility to turn the model into an expert system

19. Individual dimensions are easy to handle

20. New functionality to combine such
dimensions – Scenario clusters
• All tables would go into a single file
• One SYNC operation will create the entire cluster
• Case manager will run the cluster as a single case
• Cluster members will be available in browse
• Create DD only will create DD files and scripts in separate wrk folders

21. Next Steps: Running all these cases

22. Next Steps: Analyzing all these cases

23. VEDAViz offer: modus operandi
• User Provides:
• Scenario files that specify each state of each scenario dimension (along with the
model)
• SnT file with views for VEDAViz. Each row of each table will be created as a variable.
• Scenario Matrix, with a few runs marked to be tested first. Ref case identified.
• Workflow:
• KanORS-EMR sends VD files of pilot runs. User may want to tweak the scenario
definition or the matrix.
• KanORS-EMR runs the matrix and creates a VEDAViz project with the variables for all
scenarios and scenario differences
• Views of SnT file will be created for interactive use.
• Set up portals, in discussion with the User.
