Emergency Logistics in America
• In 1990s, America began to invest lots of money
to build and perfect their warning defense system
of public health emergency, aiming to defense the
potential terrorism attacks of biology, chemistry
and radioactivity material at the height of state
safety.
Emergency Logistics in America
• MMRS (Metropolitan Medical Response System)
is an important part, which played a crucial role in
the “9.11” tragedy and delivered 50 tons of
medical materials to New York in 7 hours.
Emergency Logistics in America
• In the bioterrorists’ attack of anthrax in October,
2001, the federal medicine reserve storage
delivered a great deal of medical materials to local
health departments.
• In 2002, America invested $1.1 billion to enlarge
the federal medicine reserve and added the reserve
storages from 8 to 12, which covered the whole
country.
Emergency Logistics in America
• Any domestic place can get the reserved vaccine,
antibiotics, medicine (including disinfection
facilities) and other emergency rescue materials in
12 hours.
• Besides, America invested $918 million to enlarge
the medicine reserve of state and local health
departments and developed the project titled
NEME (National Emergency Medical Extranet).
Emergency Logistics in Other Countries
• England, France, Italy and others have
made anti-bioterrorism plans and
established the anti-bioterrorism warning
defense systems after “9.11” .
Emergency Logistics in China
• How about China?
• In 2003, the outbreak of SARS (Severe Acute
Respiratory Syndrome) in China disclosed the
vulnerability of our system for emergency rescue
materials reserve and emergency distribution.
Emergency Logistics in China
• Till May 9th 2003, the State Department promulgated
“Regulations of Responding Public Health Emergency”,
and then, the system of emergency rescue materials
reserve and distribution in China is to be regulated.
What’s the problem?
• So, are we late?!
• Another question is: what should we do?
2. Analyze the problem from the
viewpoint of systems engineering
Covered by the
emergency logistics
• Keywords:
(1) Diffusion
(2) Coverage location
(3) Collaboration
Diffusion
of the
biological
virus
Covered by the
emergency logistics
Diffusion of biological virus
• Bioterrorist threats are real. They have a
huge influence on social stability, economic
development, and people’s physical and
mental health. Moreover, the influence is at
a global scale.
Diffusion of biological virus
• Some scholars have used smallpox as a case
and analyzed bio-terror response logistics.
Their results show that the diffusion of the
biological virus can be prevented in certain
degree with vaccination or contact isolation.
An example…
• Once a city is attacked by biological virus
(such as smallpox, anthrax, botulin toxin,
etc), it will construct a dangerous diffusion
network, in which each person can be
considered as a node. The disease will
diffuse to another city when the person who
has been infected moves from one place to
another.
An example…

Cover the emergency demand
• The flow of the emergency relief materials in
the emergency logistics network is driven by
the dangerous source diffusion network, which
has different structure from the general
logistics network.

Collaboration with the two networks
• So, the rule of the dangerous source
diffusion, and the collaboration between the
diffusion network and the emergency
logistics network should be available during
the construction of an anti-bioterrorism
warning defense system.
A Challenge
• However, the reality is that we don’t even know
what the virus will be and how to control it.
Additionally, we have no effective vaccine during
the initial response phase, for example, the case of
SRAS.
3. What can we do?
• Keywords:
Diffusion
Collaboration
Emergency logistics network
The rule of dangerous source
diffusion
• Although the rule of dangerous source
diffusion isn’t the major point in our research,
it is the necessary part when analyzing the
emergency demand.
• Models such as SEIR, SEIR-like, SEIRS,
SIS etc, will enlighten us during the research.
The collaboration between the two
networks
• The complex network models:
(1)The uniform network model
a> rule network model
b> random graph model
c> small-world network model
(2) scale-free network model.
The collaboration between the two
networks
• Formulate the dangerous source diffusion
network and the emergency logistics network
using the complex network models.
The collaboration between the two
networks
• Based on the characteristic that emergency
logistics network is driven by the dangerous
source diffusion network, we investigate the
collaborative relationship between the two
networks.
Optimization of the emergency
logistics network
• Study the national emergency material
storage model and optimize the distribution
system model.
Optimization of the emergency
logistics network
• Develop the emergency resource allocation
model in single city and urban
agglomeration.
Optimization of the emergency
logistics network
• Analyze the integrated and dynamic models
with both national emergency logistics
network and city emergency logistics
network.
Optimization of the emergency
logistics network
• Study the collaborative dynamic model of
the multi-level complex network
Simulation of the emergency
logistics network
• Dynamic changes of the models mentioned
above will be analyzed after the relative
parameters are identified, and MATLAB
will be used to obtain numerical simulation
results.

Research Significance
• First, it can increase our awareness of antibioterrorism, and provide examples for how to
enhance our ability to protect national security
and public safety.
Research Significance
• Second, our research results in optimization
and simulation of the network coordination
mechanisms will be disseminated widely
and provide potential applications in the
domain of systems engineering and
management.
We want to …
• 1)Analyze dynamic behavior of the
dangerous source diffusion process, discuss its
topology and marginal values, and establish
randomness and definite dangerous source
diffusion models.
• 2)Analyze both time and spatial complexity
of the dynamic multi-stage emergency logistics
network.
We want to …
• 3)Establish a multi-level complex,
coordinated network model to make sure
continuous supply and smooth operation.
• 4)Develop a multi-level dynamic simulation
algorithm for emergency logistics network.
