Step 4. Add Historical Evaluation to the RSA Module

Historical evaluation compares current data in the context of a historical record of selections.

The exact type of comparison/calculation/evaluation depends on the block that is being used.

Each historical evaluation requires two blocks.

They are:

Historical Evaluation Block		Record Block
	Eliminate Sources Based on Attribute Spacing		Record Attribute Spacing.
	Eliminate Sources Based on Rule		Record Attribute Rule.
	Eliminate Source By Percentages		Record Attribute Percentages.
	Eliminate Source By Ratio		Record Attribute Ratios.
	Eliminate Source By Pattern		Record Attribute Pattern.

Most frequently the:

Historical evaluation blocks are added to a Routing Logic Module.

Record blocks are added to an Output Logic Module.

Examples

The example computer factory adds three historical evaluations to the Routing Logic Moduls and corresponding record blocks to an Output Logic Module.

Example 4.1	Define an Eliminate Sources Based on Rule evaluation.
Example 4.2	Define an Eliminate Source By Percentages evaluation.
Example 4.3	Define an Eliminate Source By Ratio evaluation.
