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,

- . Aquatica makes underwater camera housings for divers. The process begins with a solid rectangular block of aluminum that is used to make a single housing. A computer numerically controlled (CNC) machine drills into the block to make the metal “frame” of the housing. Each block requires 15 minutes of drilling. The frame is then chemically treated in a series of baths. There is ample capacity in the treating stage. Finally, a worker must manually attach the various buttons and components to the metal housing. This assembly takes 120 minutes per housing per worker and Aquatica has 6 workers trained to do this task. The CNC machine requires a 30-minute setup time before the production of a batch can begin. a. If the CNC machine produces 14 housings between setups, what would be its capacity (in housings per hour)? b. Assuming the process is supply-constrained, what is the utilization (as a number between 0 and 1) of the CNC machine if it operates in batches of 14 housings? c.

What is the capacity of the process given the following information? Batch size = 50 parts Step 1 - Processing Time = 1 minute/part; Setup time = 20 minutes Step 2 - Processing Time = 2 minute/part; Setup time = no setup Step 3 - Processing Time = 1.5 minute/part; Setup time = no setup Your answer provided to me was 1.881 parts per minute (which also equals 112.8 parts per hour). I understand how you arrived at such answer. However, per my professor's answer key, states an answer of 30 units per hours (which could be wrong and I want to confirm), but my question is - is there any way the answer could be 30 units per hour?

- The magnetic resonance imaging (MRI) unit of St Francis hospital has 2 MRI machines and sees two kinds of patients, "regular" patients and "contrast" patients. The regular patients don't need any special preparation before imaging but the contrast patients receive an injection of "dye" that enables the physicians to see the images more clearly. Regular patients require 15 minutes in an MRI machine whereas contrast patients take on average 25 minutes in an MRI machine. Over an 8-hour day, the MRI unit receives an average of 25 regular patients and 5 contrast patients.

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?
