Validating set against set

[irfanrizwi]

Can someone suggest, how i should implement rule for ARA region based on following rule condition -
If image type is car/partial car AND if Dent is detected in ARA regions 1,2,5 or 6 AND
-IF Dent area to part area ratio is less than 0.03 then REPAIR
Else if Dent area to part area ratio is larger than 0.1 then REPLACE

Here the requirement is that for a specific part i will get multiple ARA regions identified by Model - For example for hood lets say i am getting ARA region 2,3,6 and 7.
Now based on the given rule condition the rule engine should evaluate to TRUE if any of the predicted value (i.e. 2,3,6 or 7) is falling under the required ARA regions (i.e. 1,2,5 or 6).

Please let me know what should be type of rule variable and how to write rule condition.
