Many metal manufacturing industríes use continuous operations for processing (e.g., galvanizing and annealing) while the handling unit is a discrete coil. The ends of coils are "stitched" or welded together to enable continuous processing, and the joint is later sheared off to obtain the processed coils. Processing constraints impose restrictions on the compatibility between a pair of coils that are overcome by introducing a dummy coil called stringer. This paper deals with modeling the sequencing/scheduling problem of coils to minimize stringer utilization. Heuristic and mathematical programming solution approaches are developed.
