Preface
Decision making in the dynamic and rapidly evolving world is a major
challenge.Decision making essentially involves the generation of a set of alterna-
tives and the choice ofthe most appropriate alternative for execution by answering
the following important questions:what decisions must be made,who will make
them,how and what resources will be allocated,and how will the situation will be
measured and revisited in the dynamic environment in which the system will be
operating.Also,in large organizations such as a multinational business group or a
modern nation state,it is imperative to decide what principles,style and guidelines
for decision-making are appropriate for the organization.It is essential to decide
what structure will govern the process ofdecision making.
Structured methods utilizing the theoretical and practical advances made in the
fields of mathematics,operations research,cybernetics,artificial intelligence,etc,
have become an important aid to decision making in all sectors.The theoretical
underpinnings ofsuch decision aids is the principle ofoptimization,which tries to
maximize or minimize certain combinations of conflicting variables representing
the matrix ofinterest for the decision maker under constraints imposed by the real
life situation.The empirical,common sense or subjective decision making of the
past graduated to the field of operations research based on the principle of opti-
mization and has resulted in enhanced decision aids at all levels ofan organization.
When the rules ofthe game are well laid out,when the environment in which one
operates is predictable,when the opponents are known,when the actors behave in
a deterministic manner,when variables vary within a small and narrow band,and,
when linear relations are the norm,one can try to make decisions using the stan-
dard optimization techniques.However,when the benefits of actions are unpre-
dictable, when relationships between variables may not only be non-linear and
stochastic, but actually unknown, the principle of optimization for decision
making will not help much. This is exactly the world that we are facing today.
Strategic, operational and tactical agility in quickly responding with maximum
concentration ofeffort is the absolute requirement.At the tactical and operational
level standard optimization techniques for decision making have helped to some
extent.However,at the strategic levels these techniques have not been able to make
a greater impact.
The problems in which stakes are extremely high,human perceptions and judg-
ments are involved and whose solutions have long term repercussions,fall in the
strategic level decision-making category.At this level problems are ill defined and
are usually in terms that are uncertain,fuzzy and confusing.However,the existing
problem-solving techniques based on sound mathematical principles require sys-
tematic and well-formed problems. This mismatch between problems and their
solution techniques leads to frustration and a lack ofconfidence by the top decision

makers.To solve such problems with limited amounts oftime and resources needs
the balancing of many variables. This book focuses on applying the Analytic
Hierarchy Process (AHP) for such strategic level decision-making problems.
The Analytic Hierarchy Process (AHP) is a systematic approach developed in
late 1970s to structure the experience, intuition, and heuristics-based decision
making into a well-defined methodology on the basis ofsound mathematical prin-
ciples.The AHP is suited to quantitatively arrive at the decision in the strategic
domain.It provides a formalized approach for creating solutions to decision-mak-
ing problems,where the economic justification of time invested in the decision-
making process is reflected in the better quality solutions of the complex
decision-making problems.
Strategic level decision making in the three main endeavors ofhuman existence,
i.e.,Business,Defense and Governance has been described in this book.The book
covers a variety of problems in the three domains – from vendor selection to
weapon system evaluation,from software projects management to disaster man-
agement,from factors affecting national security to factors affecting technology
proliferation.Practical case studies from the authors’experiences ofmany years in
applying the AHP in these three domains have been comprehensively dealt with.
The range ofproblems covered in the above three domains ofthe book gives a com-
prehensive exposure to the reader to the extent ofassistance that a formal method-
ology such as the Analytic Hierarchy Process (AHP) can provide to a decision
maker in evolving strategic decisions in such complex and varied domains in a
highly dynamic,uncertain,unknown,and unpredictable world.

Acknowledgements
This book has covered many years ofour practical experience in solving strategic
level decision-making problems in multiple domains. During the course of our
explorations of this field, a large number of individuals, institutions and
clients have influenced our thinking and assisted us in solving these problems
either directly or indirectly. We thank all of them. We would however like to
mention two names.Mr.Jagjeet Singh Sikka and Dr.S.V.Nagaraj have provided us
constant material and moral support during the course ofwriting this book.Their
contribution is acknowledged with gratitude.
I,Navneet Bhushan,would like to dedicate this book to my mother,Mrs.Urmil
Satya Bhushan.Over the years,she has been a remarkable source of inspiration
and a wonderful guide,besides being a solid pillar of strength.The late Dr.N.K.
Jaiswal,who introduced me to the field ofAHP,was a brilliant mathematician.This
book has been greatly influenced by his work and inputs.I would like to thank Mr.
S.C.Jethi,who helped me evolve into an analyst by his keen insights and unparal-
leled support. Dr. N.K. Jain’s support and morale-boosting doses are acknowl-
edged with gratitude. My sisters Kanupriya and Venu Kapoor have always
provided unacknowledged support to me.They deserve special mention in this
book.Encouragements by Mr.Eshu Jain during this project are acknowledged
gratefully.Above all,Ashi Bhushan,my wife,has been more than a co-author ofthis
work.Her love and sacrifices during the course ofwriting ofthis book have egged
me on and on.Our son Srijan and daughter Snigdha have missed their papa for
many hours due to the extra time that I worked to complete this project.I pledge
to compensate this loss by investing more time with them from now onwards.
I, Kanwal Rai, can vouch for the fact that writing a book is a journey and is
immensely more difficult (at the same time more enjoyable) than mere thinking or
planning about it! There have been a number ofinsights and learnings for me dur-
ing this journey.It is the immense and irrefutable support from my family that has
kept the vigor flowing till the very end.This book is dedicated to my parents who
have been a great source ofmotivation and support – they have always been there
to believe in my dreams and me.It is the buoyant energy and inspiration of my
wife, Kalpana Sindhu, that has kept me going forward for the seemingly insur-
mountable.Without her support, conviction and enthusiasm, it would not have
been possible to realize this dream.I would also like to extend my thanks to my
brother Naveen,sisters Anju and Sumeet,who stood solidly behind me and con-
tributed in their own sweet little ways to make this book a reality.
We owe our thanks to all our colleagues and friends who helped us by providing
their precious time to review and criticize the work constructively in order to
improve the output.There have been innumerable instances where the feedback
has not only helped to improve the quality ofcontent and presentation,but also the
authors and their thoughts in person.
