Modeling for insightsnot numbers

Amit KanudiaCork ETSAP, 31 May 2016

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.

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.

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

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.

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

VEDAViz uses powerful, flexible graphics to facilitate analysis and communication

All this takes three things

• Create clusters of scenarios

• Run all these scenarios

• Visualize a large number of scenarios in an intuitive way

Dense scenario experiments

• More points of reference

• Possibility to turn the model into an expert system

Individual dimensions are easy to handle

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

Next Steps: Running all these cases

Next Steps: Analyzing all these cases

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.
