Introduction to Operations Research


Operations Research is considered to be a foundation subject for Production and Operations Management. Though that is the case the application of OR is wide ranging from Computer Science to Finance to Engineering to ...

As per wikipedia,  

operations research, is an interdisciplinary mathematical science that focuses on the effective use of technology by organizations. In contrast, many other science & engineering disciplines focus on technology giving secondary considerations to its use.

Linear Programming, Transportation & Assignment Problems, Network Flows and Non Linear Programming are some of the areas in Operations Research.

I found the subject to be interesting, but little tough and its hard to explain or have some notes in a single post. Hence I am providing some of the links to the most simple, helpful and preservable resources available in the net.


Video Lectures:


Fundamentals of Operations Research By Prof. G. Srinivasan, Department of Management Studies, IIT Madras

Advanced Operations Research By Prof. G. Srinivasan, Department of Management Studies, IIT Madras


Lecture Notes:

Practical Optimization: A Gentle Introduction By Prof. John W. Chinneck,
Systems and Computer Engineering, Carleton University


Linear Programming: Foundations and Extensions By Robert J. Vanderbei

Course Notes By Prof. Rudi Pendavingh, Eindhoven University of Technology

If you are inclined more towards geometrical interpretations, following resources will help:


Introduction to Convex Optimization, MIT Openware Course

Video Course on Convex Optimizations:

Convex Optimization I By Professor Stephen Boyd, Stanford University

Convex Optimization II By Professor Stephen Boyd, Stanford University

Book Review : An Introduction to Operations Research by Hillier & Lieberman


A classic book for an introduction to the subject. That is clearly evident from the 40+ years that have passed since this book was published first.

All the concepts are explained very lucidly with good examples. This book covers everything from the basics to the non linear programming and at an introductory level the topics on forecasting and decision making.

The CD is a very valuable resource and the OR tutor is really good. Though a lot of other animations and applets are easily available on the net.

The book covers in depth the simplex method and also introduces other topics like application of PERT, game theory etc. A book that can be used for more than a term!

The CD comes with some extra solved problems. But I expected a lot more considering this book exists for decades! Also this book lacks coverage of any of the geometrical interpretations of linear programming.

Overall, a book that can be preserved for life time!

Don't forget to go through the CD and the Student Resources @

2010: A year that was...


2010 was one of the important years in my life! It started with lots of frustration in work, fights with managers on various issues and a January that I eagerly waited for a good CAT result. Unfortunately, I didn't get any calls and that was the point when I felt totally helpless!

However, the month of March changed everything with IIMB giving an interview call, though I was still pinched in work. I was happy and the interview went well. But, the final result was again a 'too near, yet too far' with I ending up in the waiting list. The waiting list for PGSEM rarely changes and hence I started preparing again for CAT 2010!! However the good news came in the 3rd week of May(just a week to start the classes) that finally IIMB has opened gates for me!!

8 months have passed by now. I have learn t already 10 subjects, attended a couple of business festivals, helped organizing events and attended lots of so called 'industry talks'. I will be able to grasp some of the aspects in the annual reports of companies, discuss authoritatively on the fiscal & monetary policies :p and strategies of companies and do an industry analysis!

I can forecast roughly anything since everything follows a normal distribution(side effects of the subject on probability & statistics :) ) and mentor managers on the importance of organizational structure, culture & behavior!

Two more years of gyaan on management & business and hopefully by then I will become equipped to become a good business leader :)

I hope you all enjoy reading the posts in this blog. Please provide your valuable comments...

Wish you all a happy new year!
