Sample of Active Projects:
1. Military Operations other than War
Sponsor: National Ground Intelligence Center
We are collaborating with the US Military Academy to develop and
test a principled methodology using risk modeling and assessment
techniques and criteria to create a sufficient information base
to support operations other than war (OOTW). The effort builds on
our combined experience in military operations and science,
systems engineering, and risk assessment and management. The team
is developing hierarchical holographic models (HHM) to
characterize the OOTW knowledge needs and a suite of maps and
visualization tools to provide access to the resulting databases.
2. Hurricane Preparedness and Recovery for a Highway Agency
Sponsor: Virginia Department of Transportation
The havoc inflicted by natural disasters, particularly
hurricanes, can debilitate a community, and impairment of road
transportation in particular diminishes our ability to transport
people, equipment, and resources needed for the restoration of
infrastructure. Our effort aids the highway agency to improve hurricane preparedness and recovery through the identification of planning and management options and the assessment and evaluation of the associated costs, benefits, and risks.
Furthermore, we help to identify and coordinate the needs of
recovery stakeholders within and outside of the highway agency.
3. Risk-Based Management of Guardrails
Sponsor: Virginia Department of Transportation
Public and ransportation-agency values concerning the location
and acceptable standards of roadway guardrails are in need of
clarification. The current practice in many states for site
selection for new guardrails and guardrail upgrades is often
driven by citizen complaints and accident history. Our goal is to
improve the allocation of resources for guardrails by developing
a process that utilizes knowledge of the costs, risks, and
benefits associated with new guardrail locations and upgrades of
existing equipment.
4. Incorporating Risk Management with Critical Infrastructure
Protection
Sponsor: Joint Program Office, US Department of Defense
The goal of this effort is to develop a risk modeling and
management framework to aid in improving the survivability of
selected defense infrastructures. We are evaluating existing risk
assessment and management methodologies of Fortune 500 companies
for use by their counterparts in defense infrastructures. We are
also performing the strategic development of risk management
methodology for eleven defense infrastructure sectors that
support both military operations and DoD business continuity.
5. Multiobjective Risk Analysis for Innovative Design of Lock
Walls
Sponsor: US Army Corps of Engineers
The Corps of Engineers has established criteria for lock wall
design that consider barge impact forces and earthquake loads for
three return period scenarios (e.g., usual (1 year return),
unusual (500 yr. return), extreme (1000 yr. return)). Depending
on the safety and economic context of the structure, the design
favors the larger return periods, leading to the highest
construction costs to meet high safety margin requirements. We
are developing a process to aid the US Army Corps of Engineers in
seeking an appropriate balance among the risks of multiple impact
hazards and present and future costs in the design of innovative
lock walls. The process is grounded in models of failure modes of
the lock walls, multiobjective decision making theory and
methodology, and assessment and management of risk of extreme
events.
6. Methodology for Performance Analysis of a Voice/Video/Data
Network
Sponsor: Comdial Corporation
Intra- and inter-office telephone networks are increasingly
pushed to capacity, in particular as the end users are demanding
higher bandwidths. For example, the digital switch of a 911 call
center or hospital performs differently depending on the mix of
basic telephones and full-screen computer and video applications.
Usage habits and peaks in traffic can also affect the users
perception of the quality of service. Losses of calls or other
data or delay in response cannot be tolerated, even as the rare
event, in many safety-critical applications. The goal of our
effort is to identify, model, and assess the tradeoffs (cost,
performance, reliability) in configuration of a digital phone
switch and network.
