Abstract
This paper investigates the skiving and cutting stock problem (SCSP) encountered in the paper and plastic film industries, in which a set of non-standard reels generated from previous cutting processes are used to produce finished rolls through the skiving and cutting process. First, reels are skived together length-wise to form a reel-pyramid (a polygon) and then, the reel-pyramid is cut into finished rolls of small widths. Depending on if a reel can be divided length-wise into sub-reels to form the reel-pyramid, the problem can be classified into divisible SCSP (DSCSP) and indivisible SCSP (ISCSP). In this paper, two integer programming (IP) models are proposed for DSCSP and ISCSP respectively. A sequential value correction procedure combined with the two IP models (SVCTIP) is developed to solve the two SCSPs. The effectiveness of the SVCTIP is demonstrated though extensive computational tests.
