(a) Discuss briefly the four basic components of any queueing system.
(b) Explain what you understand by the following models:
(i) (M| M | 1 : N | FCFS)
(ii) (M| M | S : ∞| SIRO)
(iii) (M| Ek | 1 : ∞ | FCFS)
(c) A supermarket has two ladies at the sales counters. Given that the service for each customer is exponential with mean 6 minutes and customers arrive in a Poisson fashion at the counter at the rate of 15 per hour, Determine
