I have 2 boxes, lets say each size of 5x5 and I have 3 items two size 4x4 and one item size is 3x3. planner initially planner assigning as follows... I - When I use 3 items 2 boxes....(this produce wrong planning) item1 (4x4) --> box1 (5x5) item2 (4x4) --> box2 (5x5) item3 (4x4) --> box1 (5x5) II - When I use 2 item, result as follows...(this is correct planning) item1 (4x4) --> box1 (5x5) item2 (4x4) --> box2 (5x5) III - When I increase one more box....(this is correct too) item1 (4x4) --> box1 item2 (4x4) --> box2 item3 (4x4) --> box3 you can see the test I - it is over writing the first assignment and assign the new item there in the box 1, I unable to figure it out how to solve this problem, I suspect this can be done in the score calculation rules, the problem is I do not know how to implement to avoid the overwriting assignments. thanks, ----- with kind regards, -- View this message in context: http://drools.46999.n3.nabble.com/how-to-avaide-overwrinting-results-in-d...
