I don't think it'd be too hard to model a decision tree in a .drl file. You'd need a rule for each node/transition in your graph. Something like: WHEN $cn : CurrentNode( Node(name == "Is the dispute related to Unauthorised") ) $d : Decision ( answer = "Yes" ) $nextNode : Node (name == "CM disputes the charge..") THEN retract $cn retract $d insert new CurrentNode($nextNode) END Then create rules that halt at nodes that have no transitions leading out of them (end nodes). You could then start it as a statefull session, and input the decisions one by one until an end node is reached. I've done that kind of thing before and it's not been too cumbersome. But then I don't know the context of what you are doing.. -- View this message in context: http://drools.46999.n3.nabble.com/Decision-tree-Is-this-scenario-possible...

okay,thanks for the reply.So, Drl files would be out of picture, i mean it would be very cumbersome to try to design a flow using insertLogical() (Truth maintenance systems).The screenshot i provided is just one fourth part of the whole scenario and i have to work on more scenarios. And in decision table it is very difficult to include drools expert language constructs. Two more queries,would be great if you can answer them 1)What would you suggest should i try to build my own logic? 2)Is there anything in Drools 6.0.0 beta version which would support decision trees? ( i saw something about neural networks in drools 6 features presentation). Thanks Atif -- View this message in context: http://drools.46999.n3.nabble.com/Decision-tree-Is-this-scenario-possible...
