(i) Queue Discipline: Queue discipline refers to the set of rules and procedures that govern how customers are served in a queue. This can include rules such as first-come, first-served, priority service for certain customers, or appointments for specific times. Queue discipline can also include procedures for handling disputes or complaints, or for managing the flow of customers through the queue.

(ii) Queueing System: A queueing system is a mathematical model that describes the behavior of a queue, including the arrival and departure of customers, the number of customers in the queue, and the time customers spend waiting in the queue. Queueing systems can be used to analyze and optimize the performance of a queue, and to make predictions about the number of customers in the queue and the time they spend waiting.

(iii) Multi-channel Service Facility: A multi-channel service facility is a type of queuing system that allows customers to receive service through multiple channels, such as in-person, over the phone, or online. This can help organizations increase efficiency and reduce wait times by allowing customers to choose the channel that is most convenient for them.

(iv) Waiting Time: Waiting time refers to the amount of time a customer spends waiting in a queue before they are served. This can include the time spent waiting in line, as well as the time spent waiting for service once they reach the front of the queue. Waiting time is a key metric in queueing systems, and can be used to analyze and optimize the performance of a queue.
