1) A fast-food franchise is considering opening a drive-up window food service operation. Assume that customer arrivals follow a Poisson distribution ( interarrival times follow an exponential distribution), with a mean arrival rate of 24 cars per hour, and that service times follow an exponential probability distribution. Arriving customers place orders at an intercom station at the back of the parking lot and then drive up to the service window to pay for and receive their order. The following four...
Question 1 Simulate the operation of a first-in-first-out queuing system until time TE = 30 minutes, using the interarrival and service-times given below (in minutes) in the given order. Interarrival times: 4, 3, 1, 1, 5, 7, 10 Service times: 4, 4, 6, 9, 8, 7, 4, 6 Given that the first arrival occurs at time t = 0, create a record of hand simulation (on the table given in the last page) using the event-scheduling algorithm and compute the...
A fast food franchise is considering a drive-up window food-service operation. Assume that customer arrivals follow a Poisson probability distribution with a mean arrival rate of 24 cars per hour, and that service times follow an exponential probability distribution. Arriving customers place orders at an intercom station at the back of the parking lot and then drive up to the service window to pay for and receive their order. The following three service alternatives are being considered: a) A single-channel...
Question 2 A fast-food franchise is considering operating a drive-up window food-service operation. Assume that customer arrivals follow a Poisson probability distribution, with an arrival rate of 24 cars per hour, and that service times follow an exponential probability distribution. Arriving customers place orders at an intercom station at the back of the parking lot and then drive to the service window to pay for and receive their orders. The following three service alternatives are being considered: A single-channel operation...
The Burger Dome waiting line model studies the waiting time of customers at its fast-food restaurant. Burger Dome's single-server waiting line system has an arrival rate of 0.75 customers per minute and a service rate of 1 customer per minute. Adapt the Black Sheep Scarves spreadsheet shown below to simulate the operation of this waiting line. Make sure to use the random values for both interarrival and service times generated in the worksheet_12-23. Assuming that customer arrivals follow a Poisson...
Question 2 Customers arrive at the checkout counter (shown in the figure below) at random from 1 to 8 minutes apart. Each possible value of inter-arrival time has the same probability of occurrence, as shown in Table 2.6. The service times vary from 1 to 6 minutes with the probabilities shown in Table 2.7.

Joey works at a interarrival times (in minutes) .chocolate store. Starting at time 0, we have the following 4 customer Bill Angie Ursula Tom 2 2 Customers are served in alphabetical order (though get displaced by a higher-priority customer). The 4 customers order the following numbers of chocolate products, respectively once you start service, you don't 6 2 3 1 Suppose it takes Joey 3 minutes to prepare each chocolate product. Further suppose that he charges $2/chocolate. Unfortunately, the customers...
**LOOKING FOR FORMULAS, ANSWERS PROVIDED. Problem-1: At a single-phase, multiple-channel service facility, customers arrive randomly. Statistical analysis of past data shows that the interarrival time has a mean of 20 minutes and a standard deviation of 4 minutes. The service time per customer has a mean of 15 minutes and a standard deviation of 5 minutes. The waiting cost is $200 per customer per hour. The server cost is $25 per server per hour. Assume general probability distribution and no...
Consider a single-server queueing system with arrival and service details as: Interarrival times: 3, 2, 6, 2, 4, 5 Service times: 2, 5, 5, 8, 4, 5 Prepare a table show below for the given data. Stop simulation when the clock reaches 20. Write a Java program, to implement this single-server queueing system, print out the table shown below: You should create a future event list in your Java code, and print out the contents of FE list in each...
In Java, complete the following: During the lunch hour, the ATM machine in a large office complex is in heavy demand. Customers complain that the waiting time is much too long. The local bank considering the addition of a second ATM machine. But first, the bank needs a few statistics to justify the cost of adding a second ATM machine. Using a Queue, simulate a waiting line at the ATM machine for a period of one hour. Make the following...
