Abstract
A dynamic insulated glass unit (IGU) assembly line scheduler is provided for production control of an IGU assembly line. When calculating the IGU assembly line order and controls, the scheduler evaluates at least i) a changeable set of uniquely identifiable glass lite storage loading locations adjacent a loading station, ii) a changeable set of uniquely identifiable IGU storage locations adjacent a unloading station, iii) a changeable identifiable subset of the set of uniquely identifiable IGU storage locations, and iv) a assembly line change outs to be performed at least in the production of the IGUs for the next in line set of IGUs to be shipped from the IGU assembly line. The scheduler is configured to re-evaluate the IGU assembly order at least with the filling of each next in line set of IGUs to be shipped.
