Abstract
Raw rolls and/or sheets of flat sheet stock are charted by a processing system that generates charting patterns using constraint logic programming, that matches the charting patterns and available raw rolls and/or sheets of flat sheet stock, and that selects the optimal patterns from those matching charting patterns and available raw rolls and/or sheets using mixed integer linear programming.
Claims43
A method of producing optimal charting patterns for raw rolls and/or sheets of flat sheet stock, the method implemented by a processing system, the method comprising:
- generating charting patterns using constraint logic programming;
- matching the generated charting patterns and available raw rolls and/or sheets of flat sheet stock;
- and,
- selecting the optimal patterns from those matching generated charting patterns and available raw rolls and/or sheets using mixed integer linear programming.
A method of producing optimal charting patterns for raw rolls and/or sheets of flat sheet stock, the method implemented by a processing system, the method comprising:
- generating charting patterns relative to raw rolls and/or sheets of flat sheet stock, wherein the generating of charting patterns is based on customer order information;
- matching the generated charting patterns and available raw rolls and/or sheets of flat sheet stock;
- and,
- selecting optimally matching generated charting patterns and available raw rolls and/or sheets of flat sheet stock, wherein the selecting of optimally matching generated charting patterns and available raw rolls and/or sheets of flat sheet stock comprises minimizing an objective function, wherein the minimizing of an objective function includes minimizing trim loss when the raw rolls and/or sheets of flat sheet stock are trimmed to fill a customer order, and wherein the objective function includes at least a first term based on matching generated charting patterns to available raw rolls and a second term based on aging raw rolls.
A computer readable memory having program code stored thereon which, when executed, performs the following functions:
- generating charting patterns based on customer order information;
- matching the generated charting patterns and available good and defective raw rolls and/or sheets of flat sheet stock;
- and,
- selecting optimally matching generated charting patterns and available good and defective raw rolls and/or sheets, wherein the selecting of optimally matching generated charting patterns and good and defective raw rolls and/or sheets comprises minimizing an objective function, and wherein the minimizing of an objective function comprises minimizing waste of the available good and defective raw rolls and/or sheets.
