Problem 1. Consider a fast food restaurant where customers arrive and get in line according to a Poisson process with an average rate of 120 customers per hour. The restaurant has one line and the amount of time it takes the cashier to serve a customer is exponentially distributed with a mean of 2 minutes. Let X_t denote the number of customers in line at time t.
1. Give the state space of the chain (X_t)t≥0.
2. For each state i,
a) find the hold time parameter i,
(b) find the embedded chain jump probabilities P_ij , (c) find the transition rates q_ij .
3. Make a transition rate diagram for the chain.
4. Assume that there are initially no customers in the system. Find the probability that there are 2 customers after 5.5 minutes

7.4 During lunch hour, customers arrive at a fast-food restaurant at the rate of T20 customers per hour. The restaurant has one line, with three workers taking food orders at independent service stations. Each worker takes an exponentially dis- tributed amount of time-on average 1 minute-to service a customer. Let X, denote the number of customers in the restaurant (in line and being serviced) at time t. The process (Xt)PO Is a continuous-time Markov chain. Exhibit the generator matrix

The number of customers arriving at a fast food restaurant are modelled on a Poisson random variable X with parameter A = 1. The total time that it takes to serve k customers, k> 1, is modelled on a continuous random variable T that is uniform in 0,k+ 1].

2. Customers arrive to a coffee cart according to a Poisson process with constant rate 12 per hour. Each customer is served by a single server and this takes an exponentially-distributed amount of time with mean 2 minutes irrespective of ev- erything else. When the coffee cart opens for service, there are already 7 people waiting. Denote by X = (X+,t> 0) the number of people waiting or in service at the coffee cart t hours...

3. A fast food restaurant has a drive-thru window. On average 40 customers arrive at the window every hour. It takes 1 minute on average to serve a customer. a. What is the average number of customers that will be in line and in service at any time? b. On average, how long will a customer spend in the system?

A Fast Food drive-through Restaurant with a single check-out counter opens six days a week, but its heaviest day of business is on Saturdays. Customers arrive at an average rate of 20 per hour on Saturdays. Customers can be provided service at the rate of one every two minutes. Assuming Poisson arrivals and exponential service times, find: The average number of customers in line The average time a car waits before being served The average time a customer spends in...

customers arrive according to a Poisson process at rate λ > 0. Assume that service crew start serving a service and it takes a fixed amount of time τ to serve. For t ≧ 0, let X(t) denote the number of customers being served at time t. What is the distribution of X(t)? What is E[X(t)]?

Customers arrive at a bank that has 1 teller and they wait in line on a first-come, first-sorved basis. Customers arrive according to a Poisson process with a rate of 14.5 per hour. It takes on average 4 minutes for a customer to be served by the tellor. No customer leaves without going through service with the teller. The standard deviation of the service time is 2 minutes. What is the average time a customer spends waiting in line? (Enter...

Customers arrive at a suburban ticket outlet at the rate of 4 per hour on Monday mornings. This can be described by a Poisson distribution. Selling the tickets and providing general information takes an average of 12 minutes per customer, and varies exponentially. There is 1 ticket agent on duty on Mondays.
