There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

TITLE: Model Uncertainty and Robust Stochastic Modeling
ABSTRACT:
Virtually any performance analysis in stochastic modeling relies on input model assumptions that, to some extent, deviate from the truth. This talk will investigate a robust framework to quantify these model errors, by positing worst-case optimizations over the input probability distributions subject to the modeler's partial, nonparametric information. We illustrate these optimization formulations in several stylized contexts in stochastic modeling, describe their computational challenges, and present some simulation-based machinery in approximating their solutions. We also illustrate their statistical connections with conventional input modeling in the stochastic simulation literature.
