Problem 4
A bakery needs to evaluate two oven solutions for its renovations. It is currently considering two
possible ovens, a small one for $1,250 and a large one for $2,500. Its operating requirements are
as follows

According to operating instructions, both the small and large ovens must be cleaned after each
batch and properly heated before each batch can be processed. The bakery estimates the demand
for the next few years to remain steady at 300,000 units per year. Currently, the company operates
8 hours a day (with no overtime allowed) and 300 days a year.
a. Calculate the daily production capacity of each oven (small and large).
b. How many of the small ovens are needed to meet the production demand? What is the total
cost?
c. How many of the large ovens are needed to meet the production demand? What is the total
cost?
d. Calculate the rate of…

Bill’s Barbershop has two barbers available to cut customers’hair. Both barbers provide roughly the same experience andskill, but one is just a little bit slower than the other. The pro-cess flow in Figure 5.9 shows that all customers go throughsteps B1 and B2 and then can be served at either of the twobarbers at step B3. The process ends for all customers atstep B4. The numbers in parentheses indicate the minutes ittakes that activity to process a customer.
a. How long does it take the average customer to completethis process?b. What single activity is the bottleneck for the entireprocess?c. How many customers can this process serve in an hour?

(Centralized System With Distributed Terminals) The following describes the conversion cycle processes for AJAX Manufacturing Inc., which employs a centralized computer system with distributed terminals in the departments. The current batch production process at AJAX is initiated from a marketing forecast of expected sales for the quarter. The production planning and control clerk uses this to create a digital production schedule of the various batches to be produced during the quarter. From this schedule, the system automatically produces digital work orders. The production department supervisor accesses the work orders from his terminal and prints the necessary hard-copy move tickets and materials requisitions. The move tickets and two copies of the purchase requisitions are distributed to each work center in the production process. Employees submit the material requisitions to storekeeping in exchange for materials and subassemblies. If additional raw…arrow_forwardA: Which station is the bottleneck?
