Question

Explain why a process can be in statistical control but not capable of meeting specifications.

**B. give an example of how the situation described in (a)
could occur in a shoe store!**

Answer #1

A process is in statistical control with x ̅ = 39.7 and R ̅ =
2.5. The control chart uses a sample size of n = 2. Specifications
are at 40 ± 5. The quality characteristic is normally
distributed.
Estimate the potential capability of the process.
Estimate the actual process capability.
How much improvement could be made in process performance if the
mean could be centered at the nominal value?

Explain the benefits of adding Statistical Process Control to an
industrial process control system.

A new process is being evaluated. After getting the
process into a state of statistical control, a sample of size 100
was taken yielding the following results: =
42.23, sample standard deviation = 1.86. The
specifications for this process are USL = 48, LSL =
36. Assuming the population is normally distributed,
compute the following:
a. Pp
b. Ppk
c. PPM

Aspen Plastics produces plastic bottles to customer order. To
monitor the
process, statistical process control charts are used. The central
line of the chart for
the sample means is set at 8.50 and the range at 0.31in. Assume
that the sample
size is 6 and the specification for the bottle neck diameter is
8.50 ± 0.25.
a. Calculate the control limits for the mean and range charts. (3
points)
b. Suppose that the standard deviation of the process distribution
is...

Honda uses statistical process control to monitor and improve a
variety of processes. Employees collect data, and then analyze it
using statistical process control charts. They can make adjustments
if needed. The statistical process control charts enable workers to
understand precisely how processes are working and anticipate
problems before they occur. One interesting use is in monitoring
the effort required to close a door. Honda monitors the speed of
the door required to make it latch by using a special...

Broody Plastics produces plastic bottles for the customer
orders. Statistical process control charts is being used to monitor
all the process. assume that the sample size is 4 and the
specification for the bottle neck diameter is 6.00+-0.35.
(Note that the central line of chart for the sample means is set
at 6.00 and the range at 0.4 in.)
(a) Calculate control limits for the mean and range charts.
(b) If the firm is looking for the three-sigma performance, is...
