An Algorithm for Two Dimensional Cutting Stock Problems with Demand
In this paper, two-dimensional cutting stock problem with demand has been studied.In this problem, cutting of large rectangular sheets into specific small pieces should be carried out hence, the waste will be minimized. Solving this problem is important to decrease waste materials in any industry that requires cutting of sheets. In most previus studies, the demand of pieces has not been usually...

متن کاملThe Number of Setups (Different Patterns) in One-Dimensional Stock Cutting
The primary objective in cutting and packing problems is trim loss or material input minimization (in stock cutting) or value maximization (when packing into a knapsack). However, in real-life production we usually have many other objectives (costs) and constraints, for example, the number of different patterns. We propose a new simple model for setup minimization (in fact, an extension of the ...
متن کاملIntegrated approaches for generating and sequencing cutting patterns in two-dimensional cutting stock problems
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...
متن کاملA simple approach to the two-dimensional guillotine cutting stock problem
Cutting stock problems are within knapsack optimization problems and are considered as a non-deterministic polynomial-time (NP)-hard problem. In this paper, two-dimensional cutting stock problems were presented in which items and stocks were rectangular and cuttings were guillotine. First, a new, practical, rapid, and heuristic method was proposed for such problems. Then, the ...
