Operations Management

1) At Quickie Car Wash, the wash process is advertised to take less than 6 minutes. Consequently, management has set a target average of 340 seconds for the wash process. Suppose the average range for a sample of 9 cars is 9 seconds.

2) Webster Chemical Company produces mastics and caulking for the construction industry. The product is blended in large mixers and then pumped into tubes and capped. Management is concerned about whether the filling process for tubes of caulking is in statistical control.

The process should be centered on 8 ounces per tube. Several samples of eight tubes were taken, each tube was weighed, and the weights in Table 5.3 were obtained.

1. Assume that only six samples are sufficient and develop the control charts for the mean and the range.
2. Plot the observations on the control chart and comment on your findings.

3) The Big Black Bird Company produces fiberglass camper tops. The process for producing the tops must be controlled so as to keep the number of dimples low. When the process was in control, the following defects were found in 10 randomly selected camper tops over an extended period of time:

1. Assuming 10 observations are adequate for this purpose, determine the three-sigma control limits for dimples per camper top.
2. Suppose that the next camper top has 15 dimples. What can you say about the process now?

4) Janice Sanders, CEO of Pine Crest Medical Clinic, is concerned over the number of times patients must wait more than 30 minutes beyond their scheduled appointments. She asked her assistant to take random samples of 64 patients to see how many in each sample had to wait more than 30 minutes. Each instance is considered a defect in the clinic process. The table below contains the data for 15 samples.

1. Assuming Janice Sanders is willing to use three-sigma control limits, construct a p-chart.
2. Based on your p-chart and the data in the table, what can you conclude about the waiting time of the patients?
