Queuing Theory, also known as- Sequencing Problem; is a subject which is taught in engineering disciplines, management studies and in B.Sc Math Honours.

Did you know Queuing Theory is used all over the world in many industries to solve real-life everyday problem of job sequencing and resource allocation ? It's also used in computer algorithms. It's a very interesting subject and is quite easy too if you can understand it!

In this tutorial the tutor will explain the Queuing Theory concepts using lots of real-life problem solving. He'll start from the very basic; from the conceptual level and will make you able to solve the problems all by yourself! He will tell you how to use the concepts to solve Queuing Theory problem very easily!

He'll tell you the concepts and theories before solving the problem just when you need it. You will really enjoy the tutorial!

## Topics Covered

1. Queuing Theory #1: All Formulae and Applicaitons:

You'll learn all the formulas you may need for solving Queuing Theory problems. You'll learn how to calculate following things and all formulas related to that-

1. Finding Utilization Parameter (Traffic Intensity)

2. Probability that queuing system is idle

3. Average time the system is idle in an 8 hour working day

4. Probability that there is 4 customers in the system

5. Number of customers in the system

6. Expected number of customers in the system

7. Expected number of customers waiting for service

8. Expected length of non-empty queue

9. Expected time a customer spends in the queue

10. Expected time a customer spends in the system

11. Probability that customer will spend more than 10 minutes in the queue waiting for service.

2. Queuing Theory #2: Airlines Industry Problem:

In this video we'll solve a Queuing Theory word problem in Operations Research(OR), related to airplane landing in an airport.

3. Queuing Theory #3: Assistant Employment Problem:

In this video we'll solve a decision making word problem in Queuing Theory in Operations Research. Our question is- There is only one cashier in a movie theatre to handle all the show bookings. We have to decide whether they need employing an assistant to assist the cashier. Based on the given data,you need to do the calculation and make the decision.

4. Queuing Theory #4: Slow-Fast Repairmen Problem:

Today we'll solve a decision making word problem in Queuing Theory in Operations Research(OR). Our question is- A factory has two repairmen for repairing of faulty machines,one is fast-but-expensive and another is slow-but-cheap; both charge Rs 5 for repairing of one machine but their repairing capacity is different. There is breakdown charge or downtime charge associated with every non-productive machine hours. Now you've to decide by appropriate calculations which repairman to employ for minimum operational cost but fast repair service.

5. Queuing Theory #5: Medical Industry Problem:

Today we'll solve a Queuing Theory word problem which includes logical decision making. Our question is- A multispeciality clinic has only one MRI machine and due to increased patient inflow,many patients have to wait in queue to get serviced. Management wants to decrease the queue size and increase the patient handling capacity. But that comes with an increased treatment fees. Now you've to calculate what should be the fees if management wants to decrease the queue size to half or less.

6. Queuing Theory #6: Restaurant Problem:

Today we'll solve a simple problem in Queuing Theory for a restaurant.

======================================

7. Queuing Theory #7: Multiple Channel Problem:

Solving a multiple channel Queuing Theory problem in Operations Research with details explanation in very easy language.

You'll learn to find-

1. Probability that queuing system is idle

2. Expected number of customers in the system

3. Expected number of customers waiting for service

4. Expected time a customer spends in the queue

5. Probability that customer has to wait for the service

All these on Multiple Channel Queuing Model.

8. Queuing Theory #8: Outsourcing Problem:

In this video we'll solve an outsourcing related IT industry problem using Queuing Theory. Our question is- A bank want to outsource maintenance of its servers to an IT company. IT company agreed to provide onsite engineers at cost of Rs 50/hr whereas downtime of each server costs the bank Rs 100/hr. Now the bank want to know how many engineers should they hire for optimal cost saving?
