The Judy Gray Income Tax Service is analyzing its customer service operations during the month prior to the April filing deadline. On the basis of past data it has been estimated that customers arrive according to a Poisson process at a rate of 5 customers per hour. The time for Judy to complete a customer interview averages 10 minutes. (Actual resturns are completed by part-time interns hired by Judy.) Based on this information, answer the following questions:
If you went to Judy, how much time would you allow for getting your return done?
On average, how much room should be allowed for the waiting area?
If Judy stayed in the offce 12 hours per day, how many hourg on average, per day, would she be busy?
What is the probability that Judy is idle?
True or false?
Qualitative flow measurement can be represented by the amount moved between departments.

Because of its excellent product and excellent location, demand has increased by 25% in the last year. On far too many occasions, customers have not been able to purchase the bread of their choice. Because of this size of the store, no new ovens can be added. At a staff meeting, one employee suggested ways to load the ovens differently so that more loaves of bread can be baked at one time. This new process will requrie that the ovens be, loaded by hand, requiring additional manpower. This is the only production change that will be made in order to meet the increased demand. The bakery currently makes 1,600 loaves per month. Employees are paid $8 per hour. In addition to the labor cost, Charles also has a constant utility cost per month of $700 and a per loaf ingredient cost of $0.50. Current multifactor productivity for 640 work hours per month= .242 loaves/dollar (round your response to three decimal places). After increasing…arrow_forward

The pay will be $ per hour for employees and each employee works 160 hours per month.Charles Lackey can also improve the yield by purchasing a new blender. The new blender will mean an increase in his investment. This new blender will mean an increase in his costs of $ per month, but he will achieve the same new output (an increase to ) as the change in labor…arrow_forwardCubway, the sandwich shop, is run by Jim, Tim and Kim. When a customer arrives, Jim spends 5 minutes taking order from the customer. After this, Tim prepares bread and Kim prepares filling for the order. These activities are performed in parallel, and take 6 and 12 minutes respectively. Jim then assembles the bread and filling, which takes 4 minutes of his time. Finally, Tim spends 1 minutes in delivering the order and taking payment. What is maximum number of sandwiches Cubway can make per hour?
