| PART -1 | Queuing Model 1( M/M/1): ( infinity(∞)/ FCFS) [ Formulae and Numericals]

In this video we will learn queuing theory model 1 single server infinite queue model in hindi in easy way.
( M/M/1): ( infinity(∞)/ FCFS)
Properties of Model 1
_________________________
Arrival follow Poisson Distribution
Service time follow exponential Distribution
Single server
infinite capacity of the system
service on first come and first serve basis
mean arrival rate is less than mean service rate

Answer is as follows for the last question :
Ls=6
Lq=5.14
Ws=0.5
Wq=0.41
P3=0.089
Ln=7

[AnujKinge]

Perfect explanation. This was the best playlist I have ever found on YouTube. Thank you!

[vishalkumarme-broll]

best lecture ever watched on youtube .Thank you sir

[aakashr]

hello sir, first of all each every lecture series regarding Operational research is very good and up-to the mark thank you for this sir. Pls make a video series on Inventory Control as it will will be beneficial for us to learn it easily from you.

[GAURAVKUMAR-jhoq]

Thank u so much sir, saver for the exam.

[mdnooralam]

Thank you so much sir for making video in series

[its.allaboutme]

respected sir,
your each and every video is too good . I really appreciate YOUR teaching, communicating style and have one suggestion your video brightness is fluctuating, which is little bit distractive.

[suvamsuvam]

Sir....why sometimes the service rate is calculated as 1/u ?

[yogeshalone]

Perfect explanation sir, Thanku so much!

[nikitadas]

Shouldn't for the queue to be non-empty, n>=1 and not just greater than 1?

[mahithakur]

Sir aapne last question ka ans. Kon si link me btaya hua h....pls btaiye mujhe match krna h

[sangavianu]

Sir, I have one doubt, for M/M/1 queue model, what is the variance of queue length?

[bhartigupta]

Sir, please make a video on derivation of waiting time distribution of Model(M/M/1):(infinity/FIFO)

[vishalmishra]

Sir please reply kijiye ... Probablity that system is idle and probabilty that there is no customer waiting to be served ... In dono me kya difference hai .... Please reply sir ji

[alenveigas]

Can u make vedios on forced vibrations?

[gulzarahmad]

probability that a queue is non empty means probability is greater or equal one ۔ is it true please explain

[YCB-insf]

sir can you plz make lecturers on inventory control, simulation model

[dharinijain]

If the question asks : What proportion of customers will have to wait before their service begins?
Will it be the same as Utilisation Factor ?

[anjaneyamishra]

Sir please MARKOV CHAINS samjha dijiye🙏🏻

[GullipalliNagabhushan]

Average length of non empty queue prove that it is required for me please
