You are developing a standard data system in the form of a database for making gaskets from various materials on different machines. You had enough time to observe 2 types of machines, A and B, for 3 materials, rubber, plastic, and cork, for 3 cycles per machine-material combination. After collecting the times, you used advanced statistics to develop a prediction equation. The table below shows the predicted times, the average time from your observations, and the percentage difference between the predicted and observed times. Show all of your work for full credit. Answers only will receive a maximum of 1 point. Material-Machine Predicted Time (h) Observed Time (h) % difference Combination Cork, A 0.239 0.231 3.43% Cork, B 0.248 0.256 3.10% Rubber, A 0.272 0.292 7.10% Rubber, B 0.280 0.260 8.00% Plastic, A 0.266 0.253 5.06% Plastic, B 0.275 0.288 4.46% 1. (3 points) If you had the chance to collect more observations on only one combination to verify data in your time study, which combination would you choose, and why? 2. You only observed the machine portion of the process for the data in the table above. In addition, you know that it takes an additional 4 minutes to load the material into the machine, and 3 minutes to unload the finished gasket and put it in the inspection tray. If the performance rating of your observed operators was 103%, and the company's PFD is set to 17%, find the following times: a. (5 points) Normal time to create one rubber gasket on machine A b. (6 points) Standard time to create one plastic gasket on machine B 3. An order comes in for 55 cork gaskets, which needs to be completed in one 8-h workday. a. (8 points) How many hours of work are needed to create this order? (You may choose the best machine type.) b. (3 points) How many machines need to be available (assuming there is one person at each machine) to meet the deadline
