Creating a Sampling Procedure 
Creating a Sampling Procedure
You can use an existing sampling procedure as a copy model. To do this, choose Sampling procedure ® Copy. Then enter the name of the sampling procedure you want to copy and choose Copy. The system displays the assignments screen with the copied data, which you can change, if necessary.
The assignments screen appears, on which you can assign a sampling type and a valuation mode to the sampling procedure, select an inspection point and set the blocking indicator.
A screen appears, on which you can determine the following special conditions for the sampling procedure.
You must enter a sampling scheme if you specified a sampling type on the assignments screen that requires a sampling scheme.
You need to enter a control chart type if you specified a fixed sample and a valuation mode that specifies a valuation on the basis of action limits.
By setting the indicator No stage change you can prevent an inspection stage change from taking place. This means that the sample size will not be dynamically modified.
If you want to use a sampling procedure without independent or dependent multiple samples, set the corresponding indicator.
If you want to work with independent or dependent multiple samples, you enter an additional valuation rule that combines the characteristic valuations for individual samples as a collective valuation, and the required number of samples (only for independent multiple samples).
If only one valid valuation rule was defined in
Customizing, the system proposes this valuation rule automatically.
Dependent multiple samples are only possible if you specified the sampling type Use sampling scheme.
If you use a sampling scheme, enter the inspection severity or the inspection severity and the AQL value.
If you chose a fixed sample and an attributive inspection for the valuation mode, enter the sample size and the acceptance number.
If you chose a fixed sample and a variable inspection for the valuation mode, enter the sample size and the k-factor.
If you chose a fixed sample without valuation parameters, enter the sample size.
If you chose a fixed sample and an attributive inspection for the valuation mode, enter the sample size and the acceptance number.
If you chose a fixed sample without valuation parameters, enter the sample size.
If you set the Free inspection points indicator on the assignments screen, you must also enter the inspection frequency.
For example, you have activated quantity- based inspection points and want to inspect after each 300 pieces. If you enter the inspection frequency 2 in the sampling procedure for a characteristic, you must carry out an inspection after every second inspection point. The sampling procedure for the next characteristic may require an inspection for each inspection point.
Once you have saved the data, if you want to create a
sampling procedure with sampling scheme, you can switch directly between the function for
maintaining allowed relationships and sampling procedures and
dynamic modification rules. Using this function, you define which combinations of sampling procedures and dynamic modification rules are compatible and can be used together in an inspection plan or for an inspection type (for sample determination and/or dynamic modification without a task list).
If you do not include the sampling procedure in the allowed relationships table, the system returns you to the initial screen and confirms that the sampling procedure was created.
