Queuing
Definition: Queuing is the management of waiting lines or queues. It involves scheduling and directing customers or items through a series of stages in a planned sequence.
Types of Queues:
First-in, first-out (FIFO): Customers or items enter the queue in the order they arrive and are processed in the order they entered.
Last-in, first-out (LIFO): Customers or items enter the queue in the order they arrive and are processed in the order they enter, with the most recently arrived items being processed first.
Priority queue: Customers or items are processed based on their priority, with higher-priority items being processed first.
Round-robin queue: Customers or items rotate through the queue in a circular fashion, with each customer or item completing a stage before moving on to the next.
Queueing Systems:
Single queue: Customers or items move through a single queue, with a single server processing them.
Multi-queue: Customers or items move through multiple queues, with multiple servers managing the queue.
Round-robin queue: Customers or items rotate through a queue, with each server processing all customers in the queue.
Characteristics of Queuing Systems:
Arrival rate: The number of customers or items entering the queue per unit of time.
Service rate: The number of servers available to process customers or items per unit of time.
Queue length: The average number of customers or items waiting in the queue.
Waiting time: The average amount of time a customer or item spends waiting in the queue.
Throughput: The number of customers or items processed per unit of time.
