Case Study: Pantry Shop (modified)

Customers arrive at the Pantry Shop store at a rate of 3 per minute and the Poisson distribution accurately defines this rate. A single cashier works at the store, and the average time to serve a customer is 15 seconds, and the exponential distribution may be used to describe the distribution of service times.

  1. What are λ and μ in this situation?
  2. Using Kendall notation, what type of queuing system is this?
  3. How many minutes does the average customer spend waiting in line?

Customers arrive to a single server system in accordance with a Poisson pro- cess with rate λ. Arrivals only enter if the server is free. Each customer is either a type 1 customer with probability p or a type 2 customer with probabil- ity 1 − p. The time it takes to serve a type i customer is exponential with rate μi , i = 1, 2. Find the average amount of time an entering customer spends in the system.

A large bank branch employs 5 tellers to serve its customers. Customers arrive according to a Poisson process at a mean rate of 3 per minute. The transaction time between the teller and customer has an exponential distribution with a mean of 1 minute. The management has established the following guidelines for the satisfactory level of service to customers: The average number of customers waiting in line to begin service should not exceed 1. At least 95% of the time,...

(4) In a shop there are two cashiers (A and B) with a single queue for them. Customers arrive at the queue as a Poisson process with rate λ, and wait for the first available cashier. If both cashiers are available, they pick one equally likely. Each cashier finishes with a customer after an exponential waiting time, with parameters µa and µb for cashier A and B, respectively. Assume that λ < µa+µb. (a) Formulate a Markov chain model with...
