Quiz 1_MScIII

As per queue discipline the following is not a negative behaviour of a customer:

• Balking

• Reneging

• Boarding

• Collussion

The dead bodies coming to a burial ground is an example of:

• Pure Birth Process

• Pure death Process

• Birth and Death Process

• Constant rate of arrival

A steady state exist in a queue if:

•  $\lambda>\mu$  

•  $\lambda<\mu$  

•  $\lambda\le\mu$  

•  $\lambda\ge\mu$  

If the operating characteristics of a queue are dependent on time, then is said to be:

• Transient State

• Busy State

• Steady State

• Explosive State

The queue discipline in stack of plates is:

• SIRO

• FIFO

• LIFO

• Non Pre-emptive

For a simple queue (M / M / 1) what is the name for
 $\rho=\frac{\lambda}{\mu}$  

• Poisson busy period

• Random factor

•  Traffic intensity

• Exponential service factor

With respect to simple queuing model which one of the given below is wrong:

•  $L_q=\lambda W_q$  

•  $\lambda=\rho\mu$  

•  $W_s=W_q+\mu$  

•  $L_s=L_q+\rho$  

If the number of arrivals during a given time period is independent of the number of arrivals that have already occurred prior to the beginning of time interval, then the new arrivals follow -----------distribution.

• Erlang

• Poisson

• Exponential

• Normal

In queue designation A/B/S : (d/f), what does S represents:

• Arrival Pattern

• Service Pattern

• Number of service channels

• Capacity of the system

Queuing models measure the effect of:

• Random arrivals

• Random service

• Effect of uncertainty on the behaviour of the queuing system

• Length of queue.
