Classification: CPC G  B | IPC G

Claim 0:
1. A method for defining a guide comprised of one or more defined sets of ordered ply orientations, the method comprising:
receiving a plurality of stacking sequence rules; and
defining the guide comprised of the one or more defined sets of ordered ply orientations in accordance with a constrained, linear integer optimization formulation, wherein defining the guide comprises:
dividing the guide into a plurality of blocks;
determining a plurality of sublaminate stacks that satisfy the plurality of stacking sequence rules and that have a size limited by a size of the plurality of blocks;
for each of the plurality of blocks, determining in accordance with the constrained, linear integer optimization formulation a sublaminate stack from among the plurality of sublaminate stacks that is compatible with a respective block; and
defining a matrix Rkbs of ply counts of plies of sublaminate stacks of the plurality of sublaminate stacks that is compatible with candidate blocks b that have an orientation angle k;
storing the guide in a memory, wherein the guide is used to define sequences of ply orientations that satisfy predetermined stacking sequence rules for a composite structure; and
guiding assembly of the composite structure according to the guide.
