d)
Explanation of Solution
Given information:
Calculation of profit per hour:
The bottleneck time is 60 seconds. Therefore, 60 units are produced every hour. Therefore, the flow rate is 60 units per hour.
The profit per hour is $45.
e)
To determine: The profit per hour of the company if the bottleneck time is reduced by 5 seconds per unit.
e)
Explanation of Solution
Given information:

OPERATION MANAGEMENT
- Rocky’s Pre-Cast Shop is considering two different processes for completing Pre-Cast jobs. Process A uses one person to setup the job and do the pre-casting. If this approach is used, an experienced person can complete an average of 20 jobs per day. Process B uses two people. One person does the setup and the second person does the actual pre-casting. Setup on one job can be done while pre-casting is being completed on another but pre-casting must be completed on a job before the pre-cast machine can start processing the next. After some practice, this second process can be completed with a standard time of 10 minutes for setup and 15 minutes for actual pre-casting. In either case, assume an 8-hour day, 5 days per week, 250 days per year. 3. Assuming ideal conditions, what is the maximum capacity of process B? 4. How long would it take to process 200 jobs using process A (assume only one worker and one machine)? 5.

This involves getting haircuts, uniforms, room assignments, and a mountain of paperwork. At the Uniform Fitting station, the worker takes the measurements on the cadet (which takes about 2 minutes), then retrieves shirts, pants and hats in his/her size (which takes about 2 minutes), waits for the cadet to try on the pants (which takes about 1 minute) and then marks the pants for hemming (which takes about 1 minute). The in-processing takes place from 8 AM to 5 PM with an hour off for lunch (8 hours). __________2a. How many cadets can a single worker fit for uniforms on that hectic day? __________2b. How many workers would be needed to fit 1601 cadets in one day, if everyone works at full capacity?arrow_forwardConsider a four-step serial process with processing times given in the list below. There is one machine at each step of the process, and this is a machine-paced process. Step 1: 15 minutes per unit Step 2: 23 minutes per unit Step 3: 23 minutes per unit Step 4: 27 minutes per unit Assuming that the process starts out empty, how long will it take (in hours) to complete a batch of 123 units?

- Atlas Inc. is a toy bicycle manufacturing company producing a five-inch small versionof the bike that Lance Armstrong rode to win his first Tour de France. The assemblyline at Atlas Inc. consists of seven work stations, each performing a single step. Stationsand processing times are summarized here:• Step 1 (30 sec.): The plastic tube for the frame is cut to size.• Step 2 (20 sec.): The tube is put together.• Step 3 (35 sec.): The frame is glued together.• Step 4 (25 sec.): The frame is cleaned.• Step 5 (30 sec.): Paint is sprayed onto the frame.• Step 6 (45 sec.): Wheels are assembled.• Step 7 (40 sec.): All other parts are assembled to the frame.Under the current process layout, workers are allocated to the stations as shown here:• Worker 1: Steps 1 and 2• Worker 2: Steps 3 and 4• Worker 3: Step 5• Worker 4: Step 6• Worker 5: Step 7Assume the workers are paid $15 per hour.

The operator must follow specified safety instructions. After mixing, a sample is drawn and taken to a laboratory, where it is tested to ensure conformance to customer requirements a and specifications. Next, the mixing tank is taken to a filling station and verified to be the correct one prior to filling individual cans of paint. The filled cans go to the packing department where labels are printed and applied to the cans. They are inspected to ensure that the labels are correct and the proper quantity was produced for the customers’ order. The cans are packed in boxes and moved to shipping. a.

- Heizer and Render advises that when analyzing and designing processes to transform resources into goods, the followingquestions should be asked:- Is the process designed to achieve competitive advantage in terms of differentiation, response or low cost?- Does the process eliminate steps that do not add value?- Does the process maximize customer value as perceived by the customer?- Will the process win orders?A Time-Function Map is similar to a flow process chart, but with time added to the horizontal axis.
