Each student will spend 2 minutes at the registrationdesk before going to one of three cashiers to pay a fee for the ID card. After that, he/she will visit one of four ID processingstations to have his/her picture taken and ID card printed. Visits to the cashier and ID processing station take 10 and 20minutes respectively. If the demand rate is 0.5 student per minute, how long does it take to process 20 students, assumingthe system is full?Multiple Choice100 minutes127 minutes

n a manufacturing process, a molded part spends 7 hours in inventory before being placed in a deburring machine, where the part is processed for 2 minutes. After deburring, the part spends 4 hours in inventory waiting for its turn on the polishing machine. The part then spends 7 minutes in polishing before waiting 6 hours in line to be painted. The part goes through a painting process that takes 7 minutes, then spends 11 hours in inventory before being shipped to the customer. What is the percentage of value-added time for the part?
Consider the following tasks that must be assigned to four workers on a conveyor-paced assembly line (i.e., a machine-paced line flow). Each worker must perform at least one task. There exists unlimited demand unless stated otherwise. Time to Complete Task (seconds): Task 1: 30 Task 2: 25 Task 3: 15 Task 4: 20 Task 5: 15 Task 6: 20 Task 7: 50 Task 8: 15 Task 9: 20 Task 10: 25 Task 11: 15 Task 12: 20 The current conveyor-paced assembly-line configuration assigns the workers in the following way: • Worker 1: Tasks 1, 2, 3 • Worker 2: Tasks 4, 5, 6 • Worker 3: Tasks 7, 8, 9 • Worker 4: Tasks 10, 11, 12 What is the direct labor content (in seconds per unit)?
The following build-up diagram tracks the number of customers for a single-server queueing system (e.g., an ATM machine) from 10:00am to 10:15am on a certain day. The number of customers shown in the chart includes both those in service and waiting in line. Build-up diagram # of Customers in system (in service + waiting) 3 2 1 0 10:00 10:01 10:02 10:03 10:04 10:07 10:09 We will call the customer who arrived the earliest during this time span the first customer, the customer who arrived the second earliest the second customer, etc.. The service discipline is first-come-first-served (FCFS). According to the diagram, how long did the second customer have to wait (in minutes) before he can enter service?
Eat Well is a tiny drive-through quick food restaurant in a shopping malltown, manned by an efficient employee named John. Customers arrive at the counter at a rate of one per 15 minutes on average, with a Poisson delivery for customer entry. Each food order takes John no more than ten minutes to process. a) How many customers are handled on average at any given time? b) The anticipated amount of clients that would be represented. c) Determine the average consumer wait time in the scheme. d) How much of the day is John Idle idle?
What is flow processing, and what are its advantages and disadvantages?
state whether or not each situation would be considered “compensable time” (and why or why not). An employee of a fast food chain has to arrive at work 15 minutes early to change into the“mascot” costume and it typically takes another 15 minutes at the end of the shift to change outof the costume and properly store it. Due to the cost of the costume, employees are notallowed to take the costume home. The “mascots” typically work from 10am – 2pm, to coverthe lunch rush periods. How much time would be “compensable” for the mascots, assumingthe conditions/schedule listed above?2) George is a Radiology Technician at a local hospital and when on call, is required to be nofurther than 30 minutes away from the facility. Is the “on call” time, compensable?
Four employees at a fast-food restaurant each perform one of the four activities in serving a customer: greet customer, take order, process order, and deliver order. The processing time for each activity is given as follows: Greet customer Take order Process order Deliver order A) 50% Assume demand is unlimited. What is the average labor utilization? B) 68% C) 40% Activity D) 162% Processing time per customer 2 seconds 30 seconds 60 seconds 5 seconds
. In the welding operations of a bicycle manufacturer, a bike frame has a flow time of about 11.5 hours. The time in the welding operation is spent as follows: 2 hours waiting in front of the cutting machine for the batch to start, 2 hours waiting for the setupof the machine, 1 hour waiting for the other pieces of the batch to go through cutting, 1 minute at the cutting machine, and 3 hours waiting for the transfer to the welding machine. Then, at the welding machine, the unit spends 1 hour waiting in front of the welding machine for the batch to start, 1 hour waiting for the setup of the welding machine, 0.5 hour waiting for the other pieces of the batch to go through welding, 0.5 minute at the welding machine, and 1 hour waiting for the transfer to the next department. Determine the exact flow time. What is the value-added percentage of the flow time?
The process for renewing a driver's license at the Archer County Courthouse is as follows. First, the clerk fills out the application; then the clerk takes the driver's picture; and finally, a typist enters the information into the computer system and processes the new license. It takes an average of eight minutes to fill out an application, two minutes to take a picture, and seven minutes to process the new license. Due to county and state budget cuts, Archer County Courthouse now has only four clerks and two typists and expects to process 38 drivers/hour. What is the current labor utilization of each labor type? Do not round intermediate calculations. Round your answers to the nearest whole number. Labor utilization of clerks: Labor utilization of typists: Where is the bottleneck in this three-stage process? The ability of the system is limited to -Select- How might the job and process design be improved? The best way to help alleviate this bottleneck is by using -Select- work…

Consider the flow in Figure 7–1 but assume that no patients require follow-upappointments. All patients first check in with the single receptionist, which takesan average of 6 minutes. They are then seen by one of two nurses who take weight,blood pressure, etc., which takes an average of 10 minutes. Finally, they are seenby a GP in an examination room, which takes an average of 16 minutes. There arethree GPs. The table below summarizes this data. Assume the clinic has no waitingroom or examination room constraints.Assume that there are eight patients arriving an hour during working hours.Resource Minutes per patient Number of resourcesReceptionist 6 1Nurse 10 2Doctor 16 3a. What is the capacity of each resource?b. Which resource is the bottleneck and hence what is the capacity of the system?
