BAM Online Meeting March 31, 2007 Team Members Present: Richard Bornhorst Kathryn Poole Deepak Janardhanan Robert Grillo Shubh Krishna Meeting length: 90 minutes Discussion of model issues o Matlab modeling BAM will use Matlab to determine an appropriate method to solve ODEs (current Excel model uses Euler) o Input parameters Alpha needs to relate somehow to the people quarantined during the last time period 2 options o Work it into the equation explicitly o Calculate the % for alpha separately from other values Need to determine what input parameters will be stochastic and which can remain deterministic Beta needs to be fixed (varied during sensitivity analysis) or have a decay function Need to determine what beta levels or decay rates would appropriately represent the various control measures Need to avoid normal distributions when using stochastic inputs May want to consider ‘beta distributions’ Need to determine an appropriate time-step (results from Matlab may help with this issue) Discussion of analysis plan o The controllable parameters are alpha, gamma, beta, and phi and will be addressed in the parametric studies o The uncontrollable parameters will be addressed in the sensitivity analysis o Ro will be used to assess the overall impact of control strategies and make BAM comparable to models from previous studies Preparations for progress presentation o Project management o Resources o Input parameters o Model diagram o Model status/changes o Analysis plan o Action items Agree to online meeting on Tuesday, April 3 at 8:30 p.m. Action items and assignment of responsibilities: o All members will work on assigned progress presentation slides o Rick – Progress presentation draft o Kathryn – C++ coding o Shubh – Model updates o Deepak – Matlab analysis o Rob – Beta value research
