Consider a two-server queue with Exponential arrival rate λ. Suppose servers 1 and 2 have exponential rates μ1 and μ2, with μ1 > μ2. If server 1 becomes idle, then the customer being served by server 2 switches to server 1. condition on λ,μ1,μ2 for this system to be stable is λ< μ1+μ2

question. Under that condition, and the long-run proportion of time that server 2 is busy.

Consider a two-server queue with Exponential arrival rate λ. Suppose servers 1 and 2 have exponential rates μ1 and μ2, with μ1 > μ2. If server 1 becomes idle, then the customer being served by server 2 switches to server 1. a) Identify a condition on λ,μ1,μ2 for this system to be stable, i.e., the queue does not grow indefinitely long. b) Under that condition, and the long-run proportion of time that server 2 is busy.

Customers arrive at a two-server system according to a Poisson process having rate λ = 5. An arrival finding server 1 free will begin service with that server. An arrival finding server 1 busy and server 2 free will enter service with server 2. An arrival finding both servers busy goes away. Once a customer is served by either server, he departs the system. The service times at server i are exponential with rates µi, where µ1 = 4, µ2...

6. Consider a queueing system having two servers and no queue. There are two types of customers. Type 1 customers arrive according to a Poisson process having rate ??, and will enter the system if either server is free. The service time of a type 1 customer is exponential with rate ??. Type 2 customers arrive according to a Poisson process having rate ??. A type 2 customer requires the simultaneous use of both servers; hence, a type 2 arrival...

An entrepreneur offers services that can be modeled as an s-server Erlang loss (Erlang-B) system. Suppose the arrival rate is 4 customers per hour; the average service time is 1 hour; the entrepreneur earns $ 2.50 for each customer served; and the entrepreneur’s operating cost is $1.00 per server per hour (whether the server is busy or idle). a) The optimal number of servers, from the entrepreneur's point of view is: ?? b) If the entrepreneur deploys the optimal number...

Consider a waiting line system with the following parameters: number of servers = 4 customer arrival rate = 7 per minute customer service rate (per server) = 2 per minute coefficient of variation of interarrival times = 0.8 coefficient of variation of service times = 0.6 Find the expected length of the waiting line. (Do not assume Poisson arrivals and exponential service times). (Provide two significant digits to the right of the decimal point)

Consider an M / M / 1 queueing system with capacity N = 2. Suppose that customers arrive at the rate of λ per hour and are served at the rate of 8 per hour. a. What should the arrival rate be so that an arriving potential customer has a 50% chance of joining the queue? b. With λ chosen to satisfy the requirement of part a, what percentage of the customers who actually enter the system get served immediately?

(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...

Suppose that the customers arrive at a hamburger stand at an average rate of 49 per hour, and the arrivals follow a Poisson distribution. Joe, the stand owner, works alone and takes an average of 0.857 minutes to serve one customer.

(2 points) b) What is the average time that a customer spends waiting in the queue...
