The Office of Naval Research (Computational
Decision Making Program)
has awarded Noel Cressie (OSU) a three-year grant (10/2001 to 9/2004)
in Spatial Statistics for
Command and Control.
With larger battlespaces, command and control (C2) systems are more
distributed. In particular, they have important multivariate, spatial,
and temporal components that makes dealing with uncertainty in these
settings particularly challenging. Moreover, (statistical) inference
is required at diverse resolutions (or apertures) that are often
different from those of the data. Statistical multi-resolution
analysis and geostatistics (both empirical Bayesian approaches) are
used to address the problem of decision making in C2. Dynamic
statistical updating of the battlespace is an important aspect of the
research, resulting in rapid-response maps of the battlespace
that are accurate and easily interpretable for a battle commander.
Understanding and quantifying the behavioral psychology of enemy
nations under conflict situations (or perceived conflict situations)
can potentially lead to improved tactical counter-measures. A variety
of important strategic questions can be answered that can provide
extremely useful intelligence. For example, when threatened, does the
enemy tend to retreat and defend, or aggressively counter-attack? Does
the enemy attack in isolated pockets, or in a more uniform style? An
example of interest is the situation where intelligence data is used to
examine the positions and readiness-states of hostile mobile launcher
systems.
The location and potential threat
of mobile launcher systems can vary significantly under different
readiness states. By smoothing the spatial point pattern of mobile
launchers (at a given snapshot in time), we obtain intensity maps that
quantify the potential threat the launchers imply. Changes in the
estimated intensity maps can be inferred using computer-intensive
Monte Carlo testing methodology.
