[rules-users] incremental modification of dataset based on accumulate

I would like to use drools in following scenario.

Say, I have a goal of producing 200 vehicles (each vehicle also has a random
priority). My factory can only produce 50 vehicles a day.. Thus, with this
constraint.. my 200 vehicles will get produced over next 4 days. I would
like to notify people as to when will each vehicle get produced.

First (topmost priority) 50 vehicles will get produced tomorrow. Next 50 day
after .. and so on.

So.. in drools, I am planning to insert the entire collection of 200
vehicles into ksession. Also, planning to insert the constraint of the
factory capacity of 50 and expect the date of production to be calculated.

I think I should use accumulate function for this.. but am not getting a
clear picture as to how to do this.

Can someone help?
