0. In Queuing Theory, statistical pattern by which customers arrive over a period of time, follows:
- Option : C
- Explanation : The basic process assumed by most queuing models is that “customers” requiring service are generated over a period of time by an “input source”.
These customers enter the queuing system and join a queue. At certain times, a member of the queue is selected for service by some rule known as “service discipline”. The required service is then performed for the customer by the “service mechanism”, after which the customer leaves the system. This process is shown in Fig.
One characteristic of the input source or calling population is its “size”. The size is the total number of customers that might require service from time to time. It may be assumed to be either finite or infinite. Since the calculations are far easier for the infinite case, this assumption is always made while developing a queuing model. However, the finite assumption must be made if the rate at which the input source generates new customers is significantly affected by the number of customers in the system.
