5. Overview
It is a discipline that deals with application
of advanced analytical methods to
facilitate better decisions .
It represents the study of optimal resource
allocation.
7. Overview
Modern synonyms for Operational Research are
Management Science or Decision Science.
It is often considered to be a sub-field of
mathematics.
8. But now a days the principles and
techniques of Operational Research
are being applied in every field of
human research and development
including Health Care Sciences.
10. History
Operational Research has been existed as a
science since 1930‘s.
But as a formal discipline
Operational Research originated
by the efforts of military planner
during WorldWar II .
11. History
The analytical study of military
problems was undertaken to
provide scientific basis for
decisions to improve military
operations.
12. History
In the decade after WorldWar-II the
techniques began to be applied more
widely in problems of
business, industries and societies.
13. History
Since the time Operational Research
has expanded into a field widely used
in industries ranging from petro-
chemical to airlines, finances, logistics
and government.
Now it has become an area of active
academic and industrial research.
14. History
The techniques of Operational Research have
been applied and proven in many industries
under different names.
For instance :-
- ‘Lean’ in manufacturing.
- ‘Supply Chain’ in logistics and
- ‘Yield Management’ in airlines.
15. Origin of Operational Research
in Medicine and Public Heath
Operational Research has been
studied in Health Care settings
since 1952.
16. In England , Norman Bailey published
“Operational Research in Medicine” in the
June issue in Operational Research Quarterly.
(Bailey June 1952).
In the same year “Journal of the Operations
Research Society” was launched in America.
17. Many Operational Research papers on health care
subjects have been published in Operational
Research and Health CareJournals.
Including –
American Journal of Public Health.(1952)
Operational Research in Medicine.
(1952 by Norman Bailey , England).
Journals of Operational Research Society.
British Medical Journal.
Heath Care Management Science.

19. Despite the proliferation of papers in
the academic literature there are still
major issues around getting
Operational Research models widely
accepted as part of mainstream
decision making by health
managers, policy makers and
clinicians.
22. Definition by WHO (2003)
“The use of systematic research techniques
for program decision making to achieve a
specific outcome.”
23. A working meeting in Geneva on -
“Framework for Operation and Implementation Research in Health and
Diseases Control Program”
All participant were agreed on -
“Any research producing practically
usable knowledge ( evidence , finding ,
information) which can improve program
implementation (effectiveness , efficiency ,
quality , access , scale-up, sustainability)
regardless the type of research (design,
method, approach) falls within the
boundaries of Operational Research.”
25. Objectives
Decision making and improve its quality.
Identify optimum solution.
Integrating the systems.
Improve the objectivity of analysis.
Minimize the cost and maximize the profit.
Improve the productivity.
Success in competition and market
leadership.
26. Objectives
The intent of Operational Research is
to learn about management and
administration of socio-cultural behavior and
economic factors that exist as bottleneck to
effective implementation and
to develop more effective approaches to the
programming.
28. Scope of Operational Research
1. National plans and budget.
2. Health care services and National Health Programs.
3. Government development and public sector unit.
4. Industrial establishment and private sector unit.
5. National defense services.
6. Research and development in engineering.
7. Public works department.
8. Business management.
9. Agriculture and irrigation projects.
10. Education and training.
11. Transport and communication.
30. Methods
Despite the number of technical labels like-
- multi-criteria decision analysis,
- linear and non linear programming,
- discrete-event simulation,
- queuing and stochastic process modeling,
- conjoint analysis or
- neural networking.
31. METHODS
Most projects of Operational Research apply
one of three broad groups of methods :-
1.Simulation methods.
2.Optimization methods.
3.Data-analysis methods.
32. 1.Simulation method
It gives ability to conduct sensitive
study to -
(a). search for improvements and
(b). test the improvement ideas
that are being made.
33. 2.Optimization methods
Here goal is to enable the decision
makers to identify and locate the
very best choice, where innumerable
feasible choices are available and
comparing them is difficult.
34. 3.Data-analysis methods
The goal is to aid the decision-maker in
detecting actual patterns and inter-
connections in the data set and
Use of this analysis for making solutions.
This method is very useful in Public Health.
36. Process
1. Identification of program problem.
2. Identification of possible reasons and
solutions .
3. Testing of potential solution.
4. Results utilization.
5. Results dissemination.
37. 1.Identification of the program problem
Most critical step in the process.
Unless problem is clearly defined it is
impossible to develop good solutions.
38. 2.Identification of possible
reasons and solutions
Once the problem has been identified , it is
the job of the program implementer and
researcher to determine the reasons for the
problem and generate possible solutions.
39. 3.Testing of potential solution
A good solution must be measurable, easy to
implement and sustainable.
To determine effectiveness of proposed
solution two designs are used-
(a) quasi-experimental design.
- comparison of situations before and after the
solution.
(b) true experiment.
- comparison of outcome between experimental and
control groups.
40. 4.Result utilization
It is necessary to decide how its results are
meant to be used.
This determine to some extent that what
information should be collected.
44. “The mission of public health
is to assure the conditions in
which people can be healthy.”
45. This mission is accomplished
by the application of
Public Health Science in
operations of Public Health
Services.
46. Operational Research ( management
principles and techniques) can be applied in
both of these areas of the Public Health.
1. Public Health Science.
2. Public Heath Services.
47. Composition of O. R. team in Public
Health
1. A Public Health Administrator.
2. An epidemiologist.
3. A mathematician.
4. A statistical scientist and
5. A social scientist.
48. Process of O.R. in Public Health
1. Formulation of the problem,
2. Collection of data,
3. Analysis and hypothesis formulation,
4. Deriving solutions from the models,
5. Choosing the optimal solution and
forecasting results,
6. Test the results and
7. Recommending implementation.
49. Uses in Public Health
1. Identify and solve the problems of program
in timely manner.
2. Helps policy maker and program manager to
make evidence based program decisions.
3. Improve program quality and performance
by using scientifically valid methods.
50. Public Health Operations
1. Disease screening and surveillance.(e.g. HIV,
Influenza)
2. Outbreak investigations.( e.g. SARS)
3. Vaccination.
4. Quarantine and isolation.(e.g.T.B.)
5. Behavioral modification program.(e.g. STDs)
6. Inspection and standard enforcement at public
establishment.( e.g. restaurants )
7. Environmental monitoring.(e.g. bacterial level
at public swimming areas)
8. Vector control.(e.g. mosquito, ticks etc.)
52. IFORS

Center for Operations Research and Training
CORT established in 1991 is one of the
leading research and training organization in
India.
Its headquarter is inVarodara ,Gujarat.
Broadly it covers area of health , demography
and social and development issues.
58. CORT
CORT is responsible for running State
Training and Resource Center (STRC) in the
state of Gujarat.
CORT is actively involved in building research
capacity of NGOs by organizing training
workshops
61. Conclusions
Operational Research needs to be integrated
as an essential part of monitoring and
evaluation efforts in Public Heath.
Thus concept of M’OR’E could become a new
paradigm for enhancing the practice of
integrated monitoring and evaluation
dimensions as one common component into
program management system.
