Abstract: This paper presents an improved genetic algorithm based on niche strategy to solve the irregular nesting problem, which exists widely in modern manufacturing industry. For the niche strategy ...
In shipbuilding, steel plates are cut into hundreds of uniquely shaped parts per vessel. Poor part arrangement on stock plates leads to 15–25% material waste. For a single vessel consuming 500+ tons ...
ABSTRACT: Two-Dimensional Irregular Strip Packing Problem is a classical cutting/packing problem. The problem is to assign, a set of 2-D irregular-shaped items to a rectangular sheet. The width of the ...
ABSTRACT: In design science, these two kinds of problems are mutually nested, however, the nesting could not blind us for the fact that their problem-solving and solution justification methods are ...
In industrial environments, nesting consists in cutting or extracting pieces from a material sheet, with the purpose of minimizing the surface of the sheet used. This problem is present in different ...
