Question

describe the three versions of Little's Law in words ..

Answer 1

1st Version ::

In queueing theory, a discipline within the mathematical theory of probability, Little's result, theorem, lemma, law, or formula is a theorem by John Little which states that the long-term average number L of customers in a stationary system is equal to the long-term average effective arrival rate λ multiplied by the average time W that a customer spends in the system. Expressed algebraically the law is

L =(λ) * (W)

2nd Version ::

The average effective arrival rate if the long term process is the division of Total number of customers to average time of customer spent

λ = L/W

3rd Version ::

The Average customer spent time is equal to the division of total number of customers to average effective arrival rate

W = L/λ
