Information, Knowledge Management
& Coordination Systems:
Complex Systems Approach
By Professor Liaquat Hossain
Globally networked risks
• Societies and organisations need
better ways to respond to sudden risk
that may emerge from multiple sources
which are interconnected and
interdependent (Helbing, 2013:Globally networked risks and
how to respond, Nature, 2 May, 51-59)

Networks and Information Flow
• Observations of interaction networks in life, engineering,
and the physical sciences suggest that the key functional
properties of these networks are:
• the flow of information they can support,
• the robustness of the flow to node failure, and
• the efficiency of the network
• Studies have also shown that certain network designs
perform better than others in each of these respects.
3
Complex Network Science: New Educational and Research Paradigm
• The solution to complex issues requires a holistic educational and research
delivery, which would cross the boundaries of social, economical, physical,
agricultural, media and communications, environmental, engineering as well
as medical and mental health systems disciplines.
• My ambition goes beyond simply being transdisciplinary in the sense of e.g.
combining sociology, political science and computational social sciences, but I
actually combine social science and natural science approaches in a more
profound sense to explore information flow in different systems.
• The outcome of my research agenda will provide a fundamental theoretical
and empirical basis for cross fertilization of robust network models across the
physical, life, socio-economic and computational science.

Why do we need to use Complex Systems Approach?
• Complex systems advocate that real-world systems are
made up from a large number of interacting components.
• this leads to complex behavior, which is difficult to
understand, predict and manage;
• Show emergence (behavior that is more than a sum of the
parts of the system alone) and self-organisation (there is no
external controller).
• It contributes to improvements in areas such as the internet,
innovation and diffusion process, sustainability, air traffic and
transport control, power systems, robotics, disease outbreaks,
irrigation and land management, security, manufacturing and
finance, as well as ecology and biology.

But control or mechanistic view advocates
“One of the most basic problems of modern management is that
the mechanical way of thinking is so ingrained in our everyday
conceptions of organization that it is often difficult to organize in
any other way” (Source: Morgan, 1986, p. 14)

Questions guiding my research for the past 10 years
• Investigating whether there is a relationship between social networks, maintenance
of the networks through ICT and its impact on performance outcomes for innovation
process, oragnisational effectiveness in stable and adversarial situations;
• Understand the formation and adaptation of hierarchical, non hierarchical, emerging
and self organized structures to explore organizational learning, innovation and
diffusion so that we can begin to characterise the types of adaptation process as
learning through feedback;
• Investigating formation and adaptation of coordinated response network involving
multi-organisational and -jurisdictional structures leading to innovative way to design
multi agency crisis response system;
• Support, equip, and enabling the ad-hoc networks (or open and user based
innovation system) of affected communities and other supporting organizations to
function effectively in crisis situations;
• Role and implications of ad-hoc networks in sharing local knowledge about the
affected areas so that warnings and intervention processes for coordination can be
effective.

Predicting Links in Health Systems (Hossain, et al.,
2013)
› Using ICD codes related to obesity from
health insurance data suggest nearly
2500 obese people averaging $5k total
in treatments, peaking at 30-40k/patient
resulting in grand total of $12.7m of full
procedure cost.
› Interestingly majority (75%+) of the
patients are female. Median of the first
treatment was at the age of 42.
› Difference between the age of patient
and the age when they had the first
treatment is about 3-6 years.
› Extended the base data set to family
members under the same policy, we
included over 7400 members, covering
850+ postcodes and 100+ hospitals.
› The graph is about 4% of the data
visualized based on 30 postcodes from
the vicinity of Sydney central. It can be
seen how obese people are connected
to the hospitals, their family members
and location. The link weights are the
dollar values, the more thick and red
they are the larger. Obese nodes are in
red, the others are blue.

Emerging Networks
not only different organizations
(agencies) need to cooperate properly
internally (intra-team & inter-team)
but also they have to cooperate with
other organizations (interorganizational)

Dynamics of disease outbreaks coordination (Bedir,
Hossain & Crawford, 2011; 2012)
› The Absence of unified approach results in different
management and coordination approaches leading
to high variability of infection rates; hence mortality
and morbidity rates.
› H1N109 infection rates in Australia
by June 17- 2009
› H109 infection in NSW) indicates that even within
the same state there were large discrepancies within
the same states with sometimes similar
demographics (by June 17- 2009)

Dynamics of disease outbreaks coordination (Bedir,
Hossain & Crawford, 2011; 2012)
Modelling challenges of disease outbreak coordination
› Therefore, we need to coordinate
between
multiple
agencies
dynamically in order to intervene
and contain dynamic form of
disease outbreaks in an evolving
environment
26
Modelling challenges of disease outbreak coordination
› Informal coordination is an important
facet of emerging coordination which
is often ignored in coordination
research
› It capitalizes on the existing
coordination channels to circumvent
their complications, inefficiencies or
even their inaccuracies.
› It can be defined
as “ when
individuals or organisations establish
communication networks outside the
standard coordination structure to
“get things done” (Baker 1981; Han
1983)”

Possible Links with Education and Research
• In my research, I use methods and analytical techniques from mathematical sociology (i.e., social networks
analysis), social anthropology (i.e., interview and field studies) and computer science (i.e., information
visualization, graph theoretic approaches and data mining techniques such as clustering);
• Using this transdisciplinary approach, I explore innovation, knowledge management and coordination
systems in distributed and complex setting for understanding distributed work groups, organizational and
individual performance and knowledge sharing and management support process for innovation and learning
