Industrial Engineering: A Closer Look at Operations Research

Operations research (OR) is a field that aims to achieve more complete datasets, consider all available options, predict all possible outcomes, and estimate risk. It involves various tools and practices that can be tailored to specific business processes or use cases to determine the most appropriate techniques for solving problems. The ultimate aim of OR is to optimize.

Course Overview

In this course, we will explore various tools and practices of operations research with the ultimate aim of optimizing problems and increasing productivity. The course is divided into several sections:

Linear Programming Problems (LPP)

In this section, we will learn how to optimize problems using methods such as the graphical method, slope method, and simplex method. We will also cover topics such as binding constraints and certain special cases.

Transportation and Assignment Problems

In this section, we will focus on optimizing transportation-related problems. We will explore popular methods such as the N-W corner rule and Vogel's approximation method. Additionally, we will delve into the Hungarian method for solving assignment problems.

Sequencing

The sequencing section will cover topics such as optimizing n jobs in one machine using the Shortest Processing Timerule (SPT) or the Earliest Due Date rule (EDD). We will also discuss optimizing n jobs in two machines.

Queuing Theory

Queuing theory is the mathematical study of queues. In this section, we will explore queuing terminologies such as arrival rate, service rate, calling population, and more.

Network Analysis: PERT and CPM

Network analysis using the Program Evaluation and Review Technique (PERT) and the Critical Path Method (CPM) is essential for project planning and execution. We will cover these topics in detail.

1. With my mechanical engineering background I was eager to learn more about LPP. This course really delivers. Thank you! ~ Ray P
2. It's a great course. I took this to brush up before I went to my masters. So, I took lot of time to learn more deeper about things which are just briefed here. Go for it ~ Darshan M V
3. I've not seen such a good explanation of transportation & assignment problems anywhere. Really good numerical practice as well ~ Praksah J
4. Very good course for quick revision ~ Sai Krishna U
5. This was marvelous. Some lectures like simplex method are needed to be re-watch to understand clearly but that's understandable. You have not only taught optimization but also optimized the course time !! Superb !! ~ Prayag S
6. Its really amazing that someone can make this tough subject so easier to grasp ~ Pradeep R
7. Interesting insights about OR. Slides are also good ~ Arnab G
