<DIV><FONT face=Arial size=2>Dear all,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Does Drools support "what-if"
analysis?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>For example, I have the data for the sales done
by a salesman for the past one year. There is a commission available to the
salesman for the same he is doing. I use the data to plot a graph showing the
efficiency of all salesmen in my company.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Assume that the comany wants a profit of , say,
10% more than what currently is, I mean "what if the comany wants more
revenue", what should be the values for sales. It is a trivial example, but
just enough for understanding my query - can we use Drools for this? Is it
being used in financial inductry where derivatives etc are used
widely?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks and regards,</FONT></DIV>
