Little's law is the relationship between

• A. Stock level and lead time in an inventory system
• B. Waiting time and length of the queue in a queuing system
• C. Number of machines and job due dates in a scheduling problem
• D. Uncertainty in the activity time and project completion time

Answer 1

Answer:

B. Waiting time and length of the queue in a queuing system

Little's Law conveys a relationship between the average number of customers (or items) in a system (L), the average arrival rate of customers (or items) to the system (λ), and the average time a customer (or item) spends in the system (W). Therefore, it is most accurately described as waiting time and length of the queue in a queuing system.
