This work presents a tailored branch‐and‐cut algorithm for the two‐dimensional irregular
strip packing problem with uncertain demand for the items to be cut. A two‐stage stochastic …

Simulated annealing (SA) is an optimization technique that can process cost functions
possessing degrees of nonlinearities, discontinuities and stochasticity. It can process …

Sawmills are a key element for the forest industry. It is not a simple task to plan correctly their
production, taking into account that there are many criteria that are appropriate for their …

In the present paper, the platform layout optimization problem for the simultaneous
fabrication of different parts, which is addressed in the batch planning of Stereolithography …

In this paper, the two-dimensional cutting/packing problem with items that correspond to
simple polygons that may contain holes are studied in which we propose algorithms based …

With the rapid development of Additive Manufacturing (AM) technology, the demand for
batch printing is increasing, whose central issue is the printing layout. In order to solve the …

Cutting raw-material into smaller parts is a fundamental phase of many production
processes. These operations originate raw-material waste that can be minimised. These …

We investigate the orthogonal packing of rectangular objects into a circular container of fixed
radius. We propose a new constructive heuristic called pack which builds a feasible packing …

Additive manufacturing (AM) technology uses the layer-by-layer stacking method to print
parts, which simplifies the process of complex parts. The requirements for batch printing in …

The irregular shape packing problem is approached. The container has a fixed width and an
open dimension to be minimized. The proposed algorithm constructively creates the solution …
