Claim:
1. A method for cutting out a plurality of pieces of glass from at least one glass sheet, comprising, in sequence: automatically generating a first optimum cutting plan, by a computer with a storage unit containing programs adapted to calculate the first optimum cutting plan for guillotine cutting at a number of hierarchical levels of different pieces from each of said at least one glass sheet, as a function of information concerning the pieces to be cut out; reading information relating to defects in said at least one glass sheet, wherein the method comprises, additionally and subsequently: automatically generating a second optimum cutting plan, by a computer with a storage unit containing programs adapted to calculate the second optimum cutting plan for guillotine cutting at a plurality of hierarchical levels from said at least one glass sheet, on the basis of said first optimum cutting plan and as a function of at least some of the information relating to the defects, including permutations of cross cut sections at the same hierarchical level within said at least one glass sheet; cutting pieces of glass in accordance with said second optimum cutting plan generated.
