A manufacturing process consists of three processes. Step 1 requires 4 minutes per unit, step 2 requires 6 minutes per unit, and step 3 requires 7 minutes per unit. 20% of units that complete the third step require rework, which means those units must start the process over at step 2 (processing times are the same for units being reworked) and rework is always successful. Demand at the shop is 0.4 units per minute.
What is the capacity of the shop (in units per minute)?
A lathe is used to process an automobile part. The processing time per part is 4 minutes. After producing 140 units of the part, the lathe requires a 46 minute maintenance process. Demand for the part is 11 units per hour.
What is the maximum inventory of a part (in units)?
A local bakery is renowned for its elaborately cecorated sheet cakes. Consider the following process information: One baker is ivailable to prepare the cake batter (measuring and mixing ingredients and then adding it to baking pans). On average, this takes 10 minutes to prepare two cakes, ie. to make enough batter for 2 cakes and to add the batter to 2 cake pans. Move time to add and remove them from the oven is neglig bile, it takes 32 minutes to bake cakes - the bakery has two ovens, each able to hold 2 cakes. The one pastry chef on staff puts on an amazing show that draws a crowd all day-each cake is decorated in 6 minutes. The bakery operates 8 hours per day.
Answer each of the following questions:
a. What is the cycle time (in minutes per cake) of each stage - preparing, baking, and decorating?
b. What is the dally process capacity? Explain.
c. If orders arrive at a rate of 3 cakes every 20 minutes, can the bakery meet the caily demand Explain,
Note: Be clear about how you…

- Charles Lackey operates a bakery in Idaho Falls, Idaho. 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).
