Example 4.3. Define an Eliminate Source By Ratio Evaluation

The computer factory has three monitor part numbers: MONO15, MONO17 and MONO19.

MONO17 has a unique stand that requires more packing time than the other two.

The number of MONO17 units that can go on line need to be limited to 1 out 5.

Eliminate Source by Ratio provides a rule that will limit selection of purchase orders that include MON17 to a 1:5 ratio.

Attribute Name	Attribute Value	BlocK Size	Block Limit	Attribute: History
MONITOR	15	30	20	TBD

Configuring this rule is done in three segments.

Example 4.3.1	Create an Eliminate Source By Ratio function block.
Example 4.3.2	Enter values for the ratio arrays.
Example 4.3.3	Add a Record Attribute Ratios function block.
