Six Sigma Configuration Dialog

Disabled Click and place a checkmark in the box in the Disabled column for items to be temporarily removed from the analysis. This does not delete the items but rather disables them from being included in the Six Sigma analysis while preserving all the information about the item.

Name Name of the analysis item selected in the Add Analysis Item dialog. This name can be modified by double-clicking in the cell. This name will be used in the title of the graph generated in Minitab.

Type Type of analysis item selected in the Add Analysis Item dialog.

Stat Collection Choose a method of statistical summarization for Six Sigma Analysis of a particular item.

• Total/Final Value For each replication run, a single value is reported which represents either a total or final value of the item being analyzed.

• Observation Over a simulation run, multiple values for an analysis item may be logged. Choose this option if analyzing each individual value in the order they were logged. When multiple replications are run, the corresponding logged values in each replication will be averaged. For example, the first value logged in each replication will be averaged, the second value in each replication will be averaged, the third values will be averaged, and so forth. The replication with the fewest number of observations will determine how many observations will be compared across replications.

• Periodic Average Allows the user to define a specific period of time over which the values logged within that period will be averaged and reported. A simulation that runs for 8 hours with a period defined as 2 hours will result in 4 averaged data points. When multiple replications are run, the replication with the fewest number of periods reported will determine how many periods to compare across replications.

Periodic Time Applies only when Periodic Average is selected for the Stat Collection. It represents a range of time that all values logged within that range will be averaged. The total number of periods depends upon the length of the simulation. For example, if a simulation runs for 8 hours and a period is defined as 2 hours, then a total of 4 periods will be the result.

Periodic Unit Applies only when Periodic Average is selected for the Stat Collection. It is the unit of time, be it seconds, minutes, hours, days, weeks, quarters, or years, for the value specified for Periodic Time.

LSL (Lower Spec Limit) – A user-defined limit that can be specified on its own or with an Upper Spec Limit. However, both the LSL and USL cannot remain blank.

USL (Upper Spec Limit) – A user-defined limit that can be specified on its own or with a Lower Spec Limit selected. However, both the USL and LSL cannot remain blank.

CI (Confidence Interval) – This value is used in generating the Capability Analysis graph in Minitab. By default, a confidence interval of 95 is automatically entered when a new Analysis Item is added to the Six Sigma Configuration table but can be modified if desired.

Launch Minitab Button – Clicking on this button will launch Minitab. If a simulation has already been run and the statistical data has been generated, the analysis items in the Six Sigma Configuration table will be summarized and graphed in Minitab.

OK Button – Click the OK button to close the Six Sigma Configuration dialog and save any changes that were made.

Cancel Button – Click the Cancel button to close the Six Sigma Configuration dialog and discard any changes that were made.
