An airline company wishes to reduce the customer waiting time at the gates at a major airport using Taguchi Design of Experiments. The management decides to use Taguchi design of experiments for this project.

Since there are 3 control factors with 2 levels in each, a total of 8 “runs” are possible. However, since performing the experiment with all possible runs is time-consuming, the management decides to consider only 4 runs.
The noise factors are four different gates assigned to the airline. The experiment data is shown in the following table:

- QUESTION 41 the z-test calculation in a run test were-2.2 and the z limits were set at +- 2 you would conclude? The process is in control The process is not in control None of the choices in this question The process is capable The process is not capablearrow_forwardThe two types of control charts for attributes are (1) x-bar chart for sample means and (2) R chart for ranges. Question 27 options: True Falsearrow_forwardQ7. A rigid vessel having a volume of 0.05 m³ initially contains carbon dioxide gas at temperature 25°C and pressure p. Ethylene gas is allowed to flow into the tank until a mixture consisting of 20% carbon dioxide and 80% ethylene (molar basis) exits within the tank at a temperature of 25°C and a pressure of 100 bar. Determine the pressure p, in bar, using Kay's rule together with the generalized compressibility chart. Answer: 46.6 bararrow_forward
- Garcia's Garage desires to create some colorful charts and graphs to illustrate how reliably its mechanics "get under the hood and fix the problem." The historic average for the proportion of customers that return for the same repair within the 30-day warranty period is 0.09. Each month, Garcia tracks 130 customers to see whether they return for warranty repairs. The results are plotted as a proportion to report progress toward the goal. If the control limits are to be set at three standard deviations on either side of the goal, determine the control limits for this chart. In March, 4 of the 130 customers in the sample group returned for warranty repairs. Is the repair process in control? The UCL equals and the LCL, equals (Enter your responses rounded to three decimal places.)arrow_forwardPlease do not give solution in image format thanku Canine Gourmet Super Breath dog treats are sold in boxes labeled with a net weight of 9 ounces (255 grams) per box. Each box contains 6 individual 1.5-ounce packets. To reduce the chances of shorting the customer, product design specifications call for the packet-filling process average to be set at 43.5 grams so that the average net weight per box of 6 packets will be 261 grams. Tolerances are set for the box to weigh 261±15 grams. The standard deviation for the packet-filling process is 1.01 grams. The target process capability ratio is 1.67. One day, the packet-filling process average weight drifts down to 43.0 grams. Is the packaging process capable? Is an adjustment needed? Since the process capability index, Cpk, is (____), the process is (_____) . (Enter your response rounded to three decimal places.)
