Background
• The number of annual disasters have tripled since 1970
• We define disasters as natural or man-made
• Natural disasters include hurricanes, cyclones and typhoons,
floods, droughts, earthquakes, volcanic eruption, epidemics,
famine and food insecurity
• Man-made disasters include war, civil war, violent conflicts,
population mass movement, displaced people, pollution or
technological disasters

Background (continued)
•
The International Federation of Red Cross Societies defines Humanitarian
Security as “all those situations in which the survival, the welfare, the health, or the
fundamental rights and liberties of people, whether entire populations or particular
social groups, are threatened”
•
Includes all those situations mentioned on the previous slide
•
Also normalisation of a country after a violent conflict, environmental problems
with the related risks involved and security problems which arise in everyday life,
such as transportation security
•
The Fritz Institute define Humanitarian Logistics as “the processes and systems
involved in mobilizing people, resources, skills and knowledge to help vulnerable
people affected by natural disasters and complex emergencies. It encompasses a
range of activities, including procurement, transport, tracking, customs clearance,
local transportation, warehousing and last mile delivery”.

Methods in Use
• Altay and Green (European Journal of Operational Research,
2006) did a literature survey on the operations research work that
has already been done in the disaster operations management
arena.
• Mathematical programming, including heuristic methods, was used
most often.
• Probability theory and statistics was used second most frequently,
while simulation appeared third on their list.
• In addition the authors discovered articles relating to decision
theory, multi-attribute utility theory and queuing theory. The
authors found system dynamics, constraint programming and soft
OR techniques to be the techniques less frequently used.

Methods in Use (continued)
• G Gallo and C Sodini (Operations Research and Conflict
Prevention, 2004) conducted research on the use of operations
research in the area of conflict prevention
• Quantitative models used in conflict prevention can be classified
into analytical models and soft operations research
• The analytical models’ main goal is to model the effects of conflict,
for example where it originated and the behaviour related to it
• Soft operations research focuses more on a framework which can
be applied to any type of conflict situation

Methods in Use (continued)
•
Logistics and Supply Chain Management is used by The Fritz Institute, San Francisco,
USA. Quantitative methods are used in Humanitarian Logistics to analyse situations, data
and improve performance of the relief chain.
•
BM Beamon (proceedings from 34th International Conference on Computers and
Industrial Engineering, 2004) looks at Humanitarian Relief Chain, and defines the
following differences between this and ordinary supply chain management:
•
•
•
•
•
•
•
•
a) Zero lead time, due to the unpredictability of disasters;
b) High risk due to involvement of a usually large number of human lives and infrastructure;
c) Incomplete or non-existent information;
d) No effective performance measurement system in place;
e) Participating humanitarian relief organizations that do not coordinate activities; and
f) Differing availability of technology from situation to situation.
I would add g) Possibility of hostile groups interfering with supply chains
She also mentions local politics and influx of humanitarian staff as things that could further complicate
matters

Methods in Use (continued)
•
L Ozdamar et al. developed a network flow model to implement on logistics planning in
emergency situations. The model addresses the transportation problem that occurs in the
event of natural disasters. Problems occur due to the time-aspect involved in rescue efforts
as well as the fact that supply is available only in limited quantities.
•
The World Food Programme is the largest humanitarian agency committed to assist in the
struggle against global hunger and poverty. Due to the transport difficulties in some
instances, they have to transport food via air. De Angelis et al. developed a multi-period
routing and scheduling model for the cargo planes in Angola.
•
Choucri and North developed a system dynamics model that showed the effects of conflict
on sustainable development such as resources and technology. They made 2 functions to

•
W Fawcett and C S Oliveira published an article that presents a new suggestion on the
problem of casualty treatment following an earthquake. They developed simulation model for
the first 4 – 5 days after the earthquake. The model assigns untreated casualties to zones

A Akkihal did a study on inventory pre-positioning for humanitarian logistics. Four million
people are left homeless annually due to the effects of natural disasters. This leads to
decreased public health and an increase in mortality. Akkihal designed a model to determine
positions for facilities (assumed to be airports) where these goods could be stored and used
in the event of a disaster. The quantitative techniques used by Akkihal were mixed-integer

J B Sheu et al. presented a fuzzy-optimization (linear programming with fuzzy variables)
model to solve the problem of relief distribution and minimise the number of casualties.
The article also presents a fuzzy vehicle routing model.

Problems with Application
•
First of all an information infrastructure is required. This consists of computer
hardware, general-purpose software, networks and communication facilities
(including the internet and intranets), databases and information management
personnel.
•
The information system must provide all the necessary data to manage a disaster or
crisis. This implicates:
•
1) there has to be access to the right data needed specifically for that crisis;
•
2) the data must furthermore have been processed in order to be in the right format
at the right time; and
•
3) correctly disseminated to the right people involved with crises management.

Problems with Application (continued)
•
L Gustavsson wrote an article on this matter (Humanitarian Logistics: Context and
Challenges), in which he points out that some of the problems are:
•
NGO’s play an all-important role in disaster management, but the role of logistics, supply
chain management and integrated systems support are greatly underestimated by NGO’s
•
No global standard of data (from previous experiences), makes it difficult for NGO’s to
share information and learn from each other
•
Communications systems form a critical part of humanitarian operations, but are usually
regarded as unimportant by NGO’s
•
NGO’s often use antiquated recording systems due to lack of investment, because of
dependency on grants – some of them still keep paper records
•
This also means that NGO’s often lack the adequate equipment to introduce more modern
methods
•
Big labour turnover due to burnout, this is often caused by having too many people to
attend to and inadequate means to do so with

Problems with Application (continued)
•
•
•
•
•
•
•
NGO’s often see corporations as “opposition” and find it hard to accept training
from them, making a passing-on of expertise more difficult
There are no concerted evaluation systems in place and every NGO does things
in its own way, making cooperation and coordination between NGO’s difficult
Often, aid workers are not adequately trained
Because of the big volunteer turnover, skills gained “in the field” are frequently not
passed on, so the NGO must start almost from scratch every time
Monitoring and evaluating underestimated by many NGO’s
Corporations are often not interested in this kind of research because there isn’t a
lot of money to be made from it, though they might have the expertise and
equipment in place to gain important results
Finally, the area of humanitarian logistics is very new, and though the necessary
methods might exist, there’s very little research done into applying them to this
particular field

Conclusions
There are several suggestions in literature for further application of operations research
methods and quantitative models to the humanitarian assistance arena
•
Statistical analysis of data has been used most frequently in the past. Most new models
are developed in the arena of linear programming and network flow models
•
There is a definite lack of literature in this field! Areas for example, the “last mile” of a relief
chain, better coordination between the agencies involved and methods to overcome the
lack of technology and power in disaster situations, need attention
•
The use of heuristic methods, simulation and other quantitative techniques could also be
further explored
•
Furthermore, it might be useful to study more operations research models with regards to,
for example transport, location or vehicle routing, as many of these models are concerned
with the probability of a “breakdown” within the transport network and humanitarian work is
subject to much uncertainty on the transport routes

Thank you!
• More research is definitely needed!
• Disasters disrupt people’s lives and livelihoods, break down
infrastructure and set back development of countries
• All research shows improvements of up to 50 % in response time,
effectiveness of relief efforts and disaster management where
quantitative methods are applied
