This work presents a hybrid approach based on the use of genetic algorithms to solve efficiently the problem of cutting structural beams arising in a local metalwork company. The problem belongs to the class of onedimensional multiple stock sizes cutting stock problem, namely 1dimensional multiple stock sizes cutting stock problem. The proposed approach handles overproduction and underproductio...

Selection of feasible cutting patterns in order to minimize the raw material wastage which is known as cutting stock problem has become a key factor of the success in today’s competitive manufacturing industries. In this paper, solving a rectangular shape medium size two-dimensional cutting stock problem is discussed. Our study is restricted to raw materials (main sheets) in a rectangular shape...

One of the main issues in the glass industry is the minimization of the trim loss generated when cutting large parts (stocks) into small items. In our application stocks are produced in the plant. Many distinct stock sizes are feasible, and technical constraints limit the variety of cutting patterns to those producing a single type of item per stock. Consequently, the focus is not on seeking an...

In this work we consider the 3-staged 2-dimensional cutting stock problem, which appears in many real-world applications such as glass and wood cutting and various scheduling tasks. We suggest a variable neighborhood search (VNS) employing “ruin-and-recreate”based very large neighborhood searches (VLNS). We further present a polynomial-sized integer linear programming model (ILP) for solving th...

In this paper the authors present a case study from the woodprocessing industry. It focuses on a cutting process in which material from stock is cut down in order to provide the items required by the customers in the desired qualities, sizes, and quantities. In particular, two aspects make this cutting process special. Firstly, the cutting process is strongly interdependent with a preceding han...

Techniques for leaf-cutting ant control have been investigated in literature due to the importance of damage they cause agriculture. Plantations with large territorial extensions, which can be contiguous or not, are usually subdivided into local administration collect data determine frequencies and area occupied by nests. The objective this work was build a relationship similarities among diffe...

This paper deals with the classical two-dimensional cutting stock problem, which consists of generating cutting patterns to produce bi rectangular items of sizes (li,wi), i=1,..,m, from rectangular objects of sizes (L,W), so that an objective is optimized, for example, the cost or trim loss. However, to cut the patterns they should be sequenced in such a way as to optimize another objective, fo...
