How To Learn Operational Research? Full Guide to Understand the LP Problems of OR

Operational Research is a very difficult subject when it comes to its understanding and most of the problems are very difficult because, converting a daily life problem into mathematics is very difficult sometimes. In this Blog post i am going to tell you about the best methods and tips to understand Operational Research problem and to get an A's into your exam.

First, every operational Research has three things.
  1. The first things is "Objective Function".
  2. The second thing is "Decision Varibles"
  3. The third thing is "Constrains"


Every problem have the following sets of things. Let discuss them one by one.

1. Objective Function:
We study Operational Research to solve any problem and that may involve "The maximizing" or "the Minimizing" 
The maximizing is related to the
  1. Profit
  2. Absorption
  3. Production 
The minimization is related to the following things in Operational research:
  1. Cost
  2. Time
  3. Allocation of something
So, whenever their is something that is describe as the max. or the min. then the best thing is to write it on that section.

2. Decision Variables:
 Look at the following problem:
Problem 1:
Reddy Mikks produce both interior and exterior paints from two raw materials, M1 and M2. The following table provides the basic data o the problem.

Tons of raw material per ton of
Exterior Paints
Interior Paints

Profit
Raw Material M1
6
4
24
Raw Material M2
1
2
6
Profit per ton($1000)
5
4

Decision Variables are

X1= Tons produce daily of exterior paints.
X2= Tons produce daily of interior paints
The objective function is to Maximize the daily demand. So, we write it as. 
The Objective function is   Max. Z=5X1 + 4X2

3. The Constrains:
Constrains are the limitation that problem have, in the above operational research problem the constrains are that the production of both type of paints should not be exceeded from 24 from that of raw material 1 and the same is true for the constrains 2 with value change from 6 or less.


Here are the 12 tips to better understand the Operational Research course:
  1. Do better planning for studying the course
  2. First, you need is to learn about the inequalities. 
  3. Inequalities in real life is more common then equalities, so better understand every and in which condition they will used. We will use Inequalities in our Operational Research.
  4.  Solve every problem of Operational Research.
  5. Watch YouTube Videos.
  6. Solve your own real life problem with Operational Research techniques.
  7. Invent your own way of solving Operational research problems. If you do this great step then the next thing is for you to validate it with more then 20 different style problems.
  8. Your objective must me to better understand it not to get good grades. Good grades are the side effect of learnings.
  9. Solve the most difficult problems of operational research.
  10. If you don't understand a single point, go and search the every possible way that help you to solve that problem.
  11. Help people those things of operational research that you already know. This will help you to learned it for whole life and at the same time if he know something that you don't then you will probably learned something new too.
  12. Help people those things of operational research that you already know. This will help you to learned it for whole life and at the same time if he know something that you don't then you will probably learned something new too.


 Which Softwares that we use to solve Operational Research problems?
Following are some of the softwares that we use to solve complex Operational Research based problem. These softwares help you to determine the answers of the problems and later on you can compare it with your own Manuel solved answer.
  • TORA
  • Lingo
  • Microsoft Excel (We solve Microsoft Solver to solve complex problems) 
If you still faced any problem related to Micrrosoft Excel feel free to comment. At the same time if you like this article still your comment make me happy.
