CorrOpti descriptions CorrOpti is a corrugator scheduling tool that generates optimal schedules. It provides various optimization criteria for the user to select from including: minimum trim ratio maximum profit maximum profit rate maximum utilization & minimum time. When maximizing the profit CorrOpti not only accounts for the cost but also for the revenue. Furthermore CorrOpti takes advantage of the allowed overruns & underruns to decide on the exact quantities that will optimize the schedule on the selected criterion. Despite performing absolute optimization CorrOpti is amazingly efficient. On a typical desktop PC it generates a schedule for tens of orders in unnoticeable time. The efficiency & responsiveness of CorrOpti make it usable in various what-if scenarios related to corrugator scheduling. For order-split control CorrOpti provides a tool that lets the user interactively maneuver through different sequencings of the schedule steps & visualize the effects on order splits along the way.
