In the textile and clothing industry, marker planning is a critical operation in the fabric-
cutting room, in which pattern pieces of different sizes and styles of a garment are laid out
on a sheet of paper with fixed width and arbitrary length in order to achieve the highest
fabric utilization (marker efficiency). The layout always contains areas of unusable fabric
due to the irregular shapes of garment pattern pieces. The minimization of fabric wastage is
crucial to the reduction of production costs. In this study, a methodology that hybridizes a
heuristic packing (HP) approach based on grid approximation with an integer
representation-based (µ + λ) evolutionary strategy (ES) is proposed in order to obtain an
efficient layout of garment patterns so as to optimize the fabric utilization. The performance
of the proposed methodology is validated by the experiments and the results demonstrate
that the proposed method provides an effective means by which to increase the marker
efficiency.
