TechFinity develops innovative
algorithms for the BMC2 environment and provides a complete solution for integrated,
modular decision architecture based on the Joint Director's Laboratory (JDL) fusion
model. TechFinity's BMC2 application currently implements key functions such as
tracking, discrimination, kill assessment, battlespace analysis, threat evaluation,
and resource management. These generalized algorithms can accommodate threats and
shooters of all types (e.g. short/long range), and sensors of all ranges
(e.g. theater, strategic), and basings. They can also be applied to layered defense
to intercept threats during threat boost, midcourse and terminal phases. The key
innovative algorithmic components are Probabilistic Battle Space Analysis, Probabilistic
Engagement Planning and Scheduling, and Sensor Resource Management.

Battle Space Analysis:
While the many-on-many (many
interceptors on many threats) engagement problem is handled
by engagement planning and scheduling (EPS), the focus of
Battle Space analysis as a core building block is on the
probabilistic solution of the one-on-one problem factoring
in all significant sources of uncertainty. TechFinity's
Battle Space analysis algorithm corrects deficiencies of
conventional algorithms by calculating the probability
distribution of an unbiased estimate of the probability
of kill. The behavior models realistically represent the
ballistic missile battle space into Single Shot Probability
of Kill as a function of threat timeline with its 'mean' and
'distribution' in multi-dimensional space. This data enables
TechFinity's engagement planning and scheduling algorithm to
generate engagement plans that exhibit more effective use of
missile defense interceptors.

Probablistic Engagement Planning and Scheduling:
TechFinity's EPS algorithms support
full use of probabilistic data, and effectively plan engagements
with high probability of kill using fewer shots and against
threats that might otherwise leak through. TechFinity's multiple
rung planner looks ahead to the time horizon till the last ground
impact time of the threats in flight. It generates engagements
in two steps, a fast initial step followed by a stochastic
improvement step that adapts to the available computational
time and power. The initial step is a multiple-rung version
of MMR in which all feasible engagements (all rung shot
opportunities if more than one exists) compete for interceptors.
The stochastic improvement step searches a neighborhood of
the initial set of engagements in a way designed to compensate
for weaknesses of the MMR algorithm, and reports the best set
of engagements found. The algorithms are parallelizable,
anytime algorithms that generate better engagements than
any conventional MMR algorithm.

Sensors Resource Management:
The primary resources of a missile defense system
are its weapons and sensors. The battle manager must manage these resources in
order to defend assets. Typically, weapon resource management and sensor resource
management are loosely coupled. TechFinity's Battle manager pioneers the coupling
of track entropy and utility to achieve more effective and highly coordinated
weapon and sensor resource management. The utility can be formulated as the
objective of engagement planning, such as expected total threat value
destroyed or expected total surviving asset value, which the Weapon resource
manager provides to the sensor resource manager. The sensor resource manager
then uses this utility function to allocate sensor resources to improve tracks,
battle space analysis, etc. to achieve the common goal of optimizing overall
utility.
Missile Defense Planner:
TechFinity's defense planning approach provides
advanced capabilities for missile defense systems with mobile assets such as
THAAD, GMD, Aegis, ABL, SBL, and MEADS. For missile defense systems with
fixed assets (or to assess a given laydown), our approach can assess system
effectiveness for new attack scenarios and strategies to counter advanced
threats, in addition to positioning new sensors and interceptor launcher
sites. Thus, our Defense Planning approach will improve the system analysis
and architecture process. More significantly, our approach will increase
system effectiveness of current systems introducing minimal software breakage
at little cost.
