What is operations research?
Operations Research (OR): applies
analytical methods to help organizations
make better decisions when solving
complex problems.
Managers use Operations Research to
make their organizations more
productive and efficient.
According Robert Penn, Operations
Research is “the application of scientific
principles to business management,
providing a quantitative basis for
complex decisions”

Operational Research: is the application of
the methods of science to complex problems
arising in the direction and management of
large number of men, machines, materials and
money, in industry, business, government and
defense.
OR is the application of scientific methods,
techniques & tools to the problems involving
the operations of a system so as to provide
those in control of the system with optimum
solution to the problem.

History of Operations Research
Operations research was born during the 2nd
World War mainly to deal with the problem of
allocation of scarce military resources for
their
optimal utilization.
British and American military strategists
jointly
delegated the task of applying scientific
approach to military problems to a selected
team of eminent scientists.
The name operations research (OR) is taken
directly from the context in which it was
developed and applied. 6

OPERATIONAL RESEARCH IN INDIA
The Operational Research Society of India was founded in 1957 to provide a forum for the
Operational Research Scientists as well as an avenue to widen their horizon by exchange
of knowledge and application of techniques from outside the country. The Society is
affiliated to the International Federation of Operational Research Societies (IFORS).
The Headquarters of the Society is located in Kolkata at 39, Mahanirvan Road, Kolkata ,
India. At present the Society has 12 Operating Chapters located in Agra, Ahmedabad,
Ajmer, Bangalore, Chennai, Delhi, Durgapur, Jamshedpur, Kolkata, Madurai,
Mumbai and Tirupati. The Objectives of the Society comprise advancement of, conducting
of research in, study of, promotion and propagation of knowledge in Operational Research
and Allied Techniques through exchange of information, as well as establishment,
improvement and maintenance of professional and academic standards of work known as
Operational Research. Contribution to the Society towards attainment of these objectives
is eligible for exemption of income tax under Section 80(G)(5)(vi) of the Income Tax Act
1961. The Society Publishes a quarterly journal OPSEARCH, which brings out high quality
and state of the art papers in Operational Research. In order to provide opportunity to
professionals and students to equip themselves with the knowledge and usage of the
science of Operational Research, the Society is conducting an examination on Graduate
Diploma in Operational Research since 1973.

2. Analyze the problem and divide into smaller units
Operational problem is analyzed in
detail.
The problem is broken into
smaller
units.
This is presented graphically.

27. Phase -I, Problem Analysis
3. Establishing Research Priorities
 First look at the system as a
whole and then as a cluster of
major subsystems.
 Then ask where one should
expect modifications to produce
the greatest positive impact on
outputs.

28. Phase -II, Solution Development
1. Specify solution objectives
 Solution objectives are statements of the desired solutions to the
operational problem.
 These are usually stated in terms of system efficiency that is
conservation of inputs and maximization of outputs.
 Fixed inputs with maximum outputs.
 Minimum inputs with maximum outputs.

29. Phase -II, Solution Development
2. Specify decision variables and
stipulate constraints on the solution
 Decision variables are factors that both play a role
in determining how a system functions and are
also within the control of the system manager.
Amount of ORS packets
Training methods
 Factors that limit the the practical range of one or
more decision variables are called constraints.
Socio-economic, ethnicity, occupation,
educational level, weather, terrain
