In Release 4.0A, the
Customizing
application contains the following new control chart types for
qualitative characteristics and quantitative characteristics with
small sample sizes (see Quality Management ->
Quality Planning -> Basic Data ->
Sample, SPC -> Control Chart -> Define
control chart type):

np-chart for the number of nonconforming units (175, 176)

p-chart for the number of nonconforming units (165, 166)

c-chart for the number of nonconformities (195, 196)

u-chart for the number of nonconformities for each unit (185,
186)

Moving-average chart (520-526)

EWMA moving-range chart for mean values with exponential
smoothing (530, 531)

Moving range chart for mean values (515, 516)

The c-chart and u-chart are provided for characteristics whose
control indicators specify the confirmation of defects. The
moving-range chart is a control chart with two tracks that is
especially suited for characteristics with a sample size of n=1. In
this case, track 1 displays the actual measured value and track 2
displays the distance between the actual measured value and the
preceding measured value.

The control limits for the moving-average chart, EWMA
moving-average chart, and the R-track of the moving range chart do
not only reference the current sample and you cannot use them to
valuate the samples.

New programs

The algorithms for the new control chart types are contained in
the following function modules:
