It looks like it's very similar to the cloud balance example.<br /><br />I've been contacted for a couple of cases, and I am currently waiting for the data of 1 vehicle routing case, which seems to be a perfect fit to what I am looking for: complex, understandable and a direct score result in cost reduction and CO² reduction. So an example I can use to prove that the ROI on improving your planning with Drools Planner is high.Geoffrey De Smethttps://www.blogger.com/profile/14668727421421215806noreply@blogger.comtag:blogger.com,1999:blog-5869426.post-34007442733903316332011-01-25T17:49:44.244+00:002011-01-25T17:49:44.244+00:00Hi,
