In Queuing Theory, statistical pattern by which customers arrive over a period of time, follows

Queuing Theory:

• The complete system of waiting in line is examined by queuing theory in operations research, encompassing elements like customer arrival rate, server count, customer count, waiting room capacity, average service completion time, and queuing discipline.
• Queuing discipline refers to the guidelines of the queue, such as whether it follows a first-in, first-out, prioritized, or serve-in-random-order system.

Important Points

• In Queuing Theory, statistical pattern by which customers arrive over a period of time follows Poisson distribution
• The number of customer arrivals in a specific time period is expressed as follows

where X=The total number of arrivals during the period
λ =the mean number of customer arrivals per unit of the time period.

Thus, in Queuing Theory, statistical pattern by which customers arrive over a period of time, follows Poisson distribution
