Complex Systems

plum colored bullet Measurement Science for Complex Information Systems:
Develop modeling and analysis methods to understand relationships among parameters and responses in large distributed systems, such as communications networks, computing grids and service-oriented architectures. Develop and refine methods to model large systems in computationally feasible form, where the number of system variables and responses become manageable. Construct abstract Markov models simulating large systems, and subject those models to perturbation-analysis to predict potential failure modes. Develop an analytical framework to understand relationships among pricing, admission control and scheduling for resource allocation in computing clusters. Develop interactive software for visualizing voluminous, multidimensional data sets generated from simulating large distributed systems. Characterize the limitations of existing fluid-approximation models of communications networks and construct improved analytical models of such networks.

Keywords: cluster analysis, correlation analysis, fluid-flow modeling, interactive multidiminesional data analysis, Markov modeling, mean-field approximation, mesoscopic modeling, orthogonal fractional factorial design, perturbation analysis, principal components analysis, sensitivity analysis, state-space reduction
