Lec-30 Queueing Models

[@prakritishrivastava6721]

This person is a true image of a brilliant teacher, simple, decent yet extraordinary in his teaching and explanation....... You are truly a gem sir

[@Ankitalala]

I have an exam in 2 hours and this lecture helped me understand things in 45 mins, that I couldn't understand in the last two days! Derivations helped in understanding the concept. Cheers Professor!

[@floris3682]

I dont know if you finished the exam yet, but how did it go?

[@kiruthikachandrasekaran523]

I am Ph.D research scholar .now I am currently doing queuing theory as my research area. This video helped me a lot to understand the concept. Thank you very much sir

This lecture is really, really good. Language barrier? What language barrier? Kudos Prof. Srinivasan, I wish more mathematicians were like you...

[@NicParsons]

incredible teacher, his english and grammar is incredible. It is so much easier to learn from someone who used full and complete sentences. I go to a quality american university and have many Teaching Assistants with english that make them very difficult to learn from(native and non native english speakers). Thank you

[@berhanumekonen5191]

Prof., your lecturing is very clear and really helpful to explore the subject matter very well. Thank you!

[@i_am_human_being5570]

Highly appreciable. Putting so many energy and efforts. You rock Sir. Felt like sitting in a real classroom.

[@ushakiranmayeegeddam3228]

Concepts are taught in a very clear way.. Thank you !

[@anupamasinha833]

Wonderfully explained.....

[@bish-jyag3371]

Bharat/India, Nepal and Himalayan civilization ( Sanatan/Vedic/Hindus culture) is such a wonderful culture, where knowledge were given to public without taking any penny and patent right. This is the teachings of hindu traditions. Lots of Hindus specially the learned Brhamins dissiminate the knowledge to illetrate people in Bharat without taking any penny in the history and also withouting claiming any authorships, lots of text were dissiminated among the population. Whereas you can see how the USA and Western countries making billions of dollars by putting patent right and hiding the new information extracted from our ancient knowledge. Great professor, without taking any penny you are dissiminating your knowledge to the public is the proof of DNA embedded to your heart by Santani tradition. God bless you!

[@hieunganlepham9655]

what a useful video!! I really like the teaching method and the way the Prof explained the theory. It has been 11 years, hope you are doing well, Prof. Thank you for this lecture.

[@CAneeravsethi]

Yes exactly

[@ShandukaniVhulondo-wn5eh]

Thank you so much Prof. for this excellent and exceptional video that makes mathematical derivation so easy to understand the concept. I appreciate the work you are doing.

[@manjunathbr1917]

Concepts are taught in simple manner.. Best explanation. Thank you very much sir..

Wonderful lecture video. Many critical concepts are excellently explained. Very good video for MCA students.

[@poornimamuthukuda6542]

You explain very well sir. We are under quarantine and universities are closed n you helped me alot in understanding this concept. Thank you.

[@iocaraballo]

Very nice video, is a good way to learn because you can rewind when you dont catch some idea. Teacher might get angry in class if you ask them more than once to repeat something and also when you want to think or digest something you can stop the video, the real teachers dont wait for you to get the idea, they just talk and ask you if you understood and we always say we did even we didnt.

[@wolesofttechnologiesltd9688]

Simply the best. Many thanks Prof. for sharing your expertise and breaking down Queueing Theory.

[@DataBeach]

Awesome Lecture from a great mind. Thanks, Professor, for this and several other amazing videos from you.

[@SAJIDALI-jp6xw]

v perfect, very cleared lecture sir,thank u v much, i clearly understand those points that me didn't got well understand in university, thanx once more........

[@rjicloudy]

Accidentally viewed this video..Priceless lecture. .I went back to my Engineering...Probability and queuing theory(PQT) screwed me..It din leave me In my MBA also...I wish i had found this in my second yr lol.....I used to write some crap on the paper but managed to clear... lol..Merci beaucoup

Thanks Professor, for your contribution to queueing analysis aspirants. I watched many videos on queueing modelling and I believe this is so far the best video on queueing modelling. Prof. I am wondering if your lectures can extended to advanced level of birth-death process then it will be more helpful to us. Thanks and Regards.

Please clear my doublt sir At a doctor's clinic patients arrive at an average rate of 10 per hour. The consultancy time per patient is exponentially distributed with an average of 6 minutes per patient. The doctor does not admit any patient if at any time 10 patients are waiting. Then at the steady state of this M|M|1|R queque the expected number of patients waiting is

Thank you sir..worth watching From assam, dibrugarh university , india🇮🇳

[@dagwould]

I'd like to see a model for multiple service points in optional sequence with different service times. This represents the queueing for tea and coffee after a conference session. Customers have varying needs: tea - black, tea-white, either with or without sugar/sweetener, some want a snack also on offer. Most conferences I've attended (only few exceptions) put everyone through the maximum service time wait: this occurs when a customer wants tea (and sometimes has to dip and dispose of their own tea-bag), then milk, then sugar, then a snack. All served from the one point. Very few break the service into three separate queues: 1. get not drink. 2 go to queue for milk if desired, or the one for sugar/sweetener, if desired, then the separate one for food. There really only needs to be three stations: hot drink, additive (sugar and milk), food. Everyone goes to 'hot drink' and is served quickly. Any waste disposed of away from the service point, then those who want an additive move to that service station. Food? Go to the separate food service station, placed some distance away. This breaks up the bottleneck activity (milk, sugar) from the high throughput activities: hot drink, and usually food, unless a person seeks to juggle hot drink and food.

[@phreaker01]

Really understandable lecture. Thank you professor.One question though: Why did you leave the higher order terms out in the probability formulae? Regards

[@phreaker01]

***** thank you kind sir. Regards.

[@sanaamin869]

As we are dealing with the single server and two events can not take place at once.therfore he ignored the higher order terms.

[@rsfx2856]

if lambda = 5 per hour and Mu = 4 per hour, it is not true that someone who joins the queue will never be seen (as stated at ~12:50 ) . This person will be seen as will all people who join the queue. What is true is that the queue will grow to infinity.

[@abdelbassetkabou3442]

Sorry, but in 45:51 why you replaced "(1-landa *h)Uh" by "Uh" ??!!

[@TheRockkers]

since h is very small instant of time ,and h*h is negligible (eg: 0.03 sec*0.03 sec= 0.0009 sec)

[@Manipalkarnataka]

this is because that the product of second order terms will be very less...so we can neglect that...(as the value of h is ends to ZERO)

Sir, Sorry to bother, but I fail to understand how does expected value (lambda*h & mu*h) act as a probability. Kindly explain. To me they are just incoming or outgoing rates.
