Origin of operations research
Definition of operations research
Characteristics of operations research
Role of operations research in decision-making
Methods of solving operations research problem
Phases in solving operations research problems
Typical problems in operations research
Scope of operations research
Why to study operations research
The operation research book that involves all units including the lpp problems, integer programming problem, queuing theory, simulation Monte Carlo and more is covered in this digital material.
OR is defined as a scientific approach to optimal decision making through modelling of
deterministic and probabilistic systems that originate from real life.
Scientific approach: LPP, PERT/CPM, Queueing model, NLP, DP,MILP, Game
theory, heuristic programming.
Deterministic system: - a system which gives the same result for a particular set of
input, no matter how many times we recalculate it
Operation research and its application
• Operations • The activities carried out in an organization.
• Research • The process of observation and testing characterized by the scientific method. Situation, problem statement, model construction, validation, experimentation, candidate solutions.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2. INTRODUCTION
Operational Research is a systematic and analytical
approach to decision making and problem solving.
O.R. is an Branch of applied mathematics that uses
techniques and statistics to arrive at Optimal solutions to
solve complex problems.
It is typically concerned with determining the
maximum profit, sale, output, crops yield and efficiency
And minimum losses, risks, cost, and time of some objective
function.
Some of the PRIMARY TOOLS used by operation
researchers are-
STATISTICS
GAME THEORY
PROBABILITY THEORY, etc.
3. Define OR ?
Operations Research is the application of
analytical methods designed to help the
decision makers choose between
various courses of action available to
accomplish specified objectives
4. HISTORY OF
OPERATIONAL RESEARCH
There is no clear history that marks the Birth if O.R., it is
generally accepted that the field originated in England during the
World War II.
Some say that Charles Babbage (1791-1871) is the Father
of O.R because his research into the cost of transportation and
sorting of mail led to England’s University Penny Post in 1840.
Modern Operations Research originated at the Bowdsey
Research Station in U.K. in 1937 to analyse and improve the
working of the UK’s Early Warning Rador System.
During the Second World War about 1000 Men and Women
were engaged to work for British Army.
After World War II, Military Operational Research in U.K.
became Operational Analysis (OA) within the U.K. Ministry of
Defence with expanded techniques and graving awareness.
5. 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 700029,
India. At present the Society has 12 Operating
Chapters located in Agra, Ahmedabad, Ajmer,
Bangalore, Chennai, Delhi, Durgapur,
Jamshedpur, Kolkata, Madurai, Mumbai and Tirupati.
9. Constructing a Model
1 Problem must be translated
from verbal, qualitative terms
to logical, quantitative terms
2 A logical model is a series of
rules, usually embodied in a
computer program
3 A mathematical model is a
collection of functional
relationships by which
allowable actions are delimited
and evaluated
10. Solving the Mathematical Model
1 Many tools are
available as discussed
in this course
2 Some lead to
“optimal” solutions
3 Others only
evaluate candidates
to trial and error to
find “best” course of
action
17. Linear Programming
Problem
A Linear Programming model seeks
to maximize or minimize a linear function,
subject to a set of linear constraints.
The linear model consists of the
following components:
A set of decision variables.
An objective function.
A set of constraints.
22. Example 1 - Max
Consider a chocolate manufacturing company which produces
only two types of chocolate – A and B. Both the chocolates require
Milk and Choco only.
To manufacture each unit of A and B, following quantities are
required:
Each unit of A requires 1 unit of Milk and 3 units of Choco
Each unit of B requires 1 unit of Milk and 2 units of Choco
The company kitchen has a total of 5 units of Milk and 12 units of
Choco. On each sale, the company makes a profit of
Rs 6 per unit A sold
Rs 5 per unit B sold.
Now, the company wishes to maximize its profit. How many units of
A and B should it produce respectively?
