RECENT THESES WITH THE MOVES INSTITUTE - JUNE 2002
Captain Alistair Dickie, Australian Army

Research in cooperation with the MOVES Institute
MODELING ROBOT SWARMS USING AGENT-BASED SIMULATION
In the near future, advances in mechanical and electrical engineering will
enable the production of a wide variety of relatively low cost robotic
vehicles. This thesis investigates the behavior of swarms of military robot=
s
acting autonomously. The Multi-Agent Robot Swarm Simulation (MARSS) was
developed for modeling the behavior of swarms of military robots. MARSS
contains state, sensing, and behavioral model building tools that allow a
range of complex entities and interactions to be represented. It is a
model-building tool that draws theory and ideas from agent-based simulation=
,
discrete event simulation, traditional operations research, search theory,
swarm theory, and experimental design. MARSS enables analysts to explore th=
e
effect of individual behavioral factors on swarm performance. The
performance response surface can be explored using designed experiments. A
model was developed in MARSS to investigate the effects of increasing
behavioral complexity for a search scenario involving a swarm of Micro Air
Vehicles (MAV=92s) searching for mobile tanks in a region. Agreement between
theoretical and simulated search scenarios for simple searchers was found.
The effect of increased MAV sensory and behavioral capability was
demonstrated to be important. Little improvement was observed in swarm
performance with these capabilities, however agent performance was adversel=
y
affected by reacting to increased knowledge in the wrong way. The utility o=
f
MARSS for conducting this type of analysis was demonstrated.

Research in cooperation with the MOVES Institute
THE EFFECT OF SOUND SPATIALIZATION ON RESPONSES TO OVERLAPPING MESSAGES
The purpose of this research was to determine if a spatialized headphone
display would improve users=92 recognition accuracy when listening to more
than two overlapping messages. This type of task has numerous applications
in a variety of different military settings, such as aviation communication=
s
and combat information centers. Two experiments were conducted in the
Advanced Auditory Displays Laboratory at the Naval Postgraduate School. The
first experiment was a pilot study, which was designed to identify the
factors that contributed to changes in response accuracy rates. The
conclusion of this effort was a decision to use a chi-squared analysis and =
a
multivariate logit regression, which could examine the influence of several
factors in addition to spatialization. Results indicated that participants
accurately identified 43% of the messages in the spatialized condition, but
only 17% of the messages in the non-spatialized condition. Chi-squared test=
s
indicated a dependent relationship between accuracy and spatialization unde=
r
a variety of conditions. The logit regression model confirmed these
conclusions and indicated that the chance of a completely correct response
was improved by approximately 30% with the use of spatialization.
MAJ Michael VanPutte, USA
<http://movesinstitute.org/Theses/vanputtediss.pdf> Ph.D. in Computer
Science in cooperation with the MOVES Institute
A COMPUTATIONAL MODEL AND MULTI-AGENT SIMULATION FOR INFORMATION ASSURANCE
The field of information assurance (IA) is too complex for current modeling
tools. While security analysts may understand individual mechanisms at a
particular moment, the interactions among the mechanisms, combined with
evolving nature of the components, make understanding the entire system
nearly impossible. This dissertation introduces a computational model of IA
called the Social-Technical Information Assurance Model (STIAM). STIAM
models organizations, informationn infrastructures, and human actors as a
complex adaptive system. STIAM provides a structured approach to express
organizational IA issues and a graphical notation for depicting the element=
s
and interactions. The model can be implemented in a computational system to
discover possible adaptive behavior in an IA environment. A multi-agent
simulation is presented that introduces several innovations in multi-agent
systems including iconnectors, a biologically inspired visual language and
mechanism for inter-agent communications.The computational model and
simulation demonstrate how complex societies of autonomous entities
interact. STIAM can be implemented as a hypothesis generator for scenario
development in computer network defensive mechanisms.
