[rules-users] Drools Rule Engine - Tiered Rates

[Greg Barton]

You can also try a data driven approach:

declare Rate
    minUnits : int
    maxUnits : int 
    revenuePercent : int
end

declare Sale
    units : int
end

rule "FindRate"
    when
        r : Rate( ) 
        s : Sale( units > r.minUnits, units < r.maxUnits )
    then
        System.out.println( "revenuePercent for " + s + " is " + r.getRevenuePercent());
end

Sample code attached.

Hi All,



   I have the following question regarding Drools. The possibility to

implement tiered rates and that is I have the following example.

   If the total units sold is between 0 - 1000 item a revenue return is 10%

while if the total units sold is between 1001- 2000 items the return is 20%.



   I want to use 1 dynamic rule to implement the above example rather than

having 2 static rules defined? is this possible through drools?





Regards

Ram
