A decomposition problem of a natural number for a rectangular cutting-covering model

چکیده
We study in this paper a cutting-covering problem, defined by us in [2] and [3], the problem of covering a rectangular support with rectangular pieces cut from a roll. We first prove that the algorithm used in [2] and [3] for the rectangular cutting-covering problem without losses is not optimal. Starting from a decomposition of a natural number in sums of naturals we develop an algorithm for a better solution for the rectangular cuttingcovering problem. Some examples and also the estimation of this algorithm’s complexity are presented. Key–Words: rectangular cutting, covering, optimization

Mathematical Model for Bi-objective Maximal Hub Covering Problem with Periodic Variations of Parameters
The problem of maximal hub covering as a challenging problem in operation research. Transportation programming seeks to find an optimal location of a set of hubs to reach maximum flow in a network. Since the main structure's parameters of the problem such as origin-destination flows, costs and travel time, change periodically in the real world applications, new issues arise in handling it. In t...
متن کاملA Fast Algorithm for Covering Rectangular Orthogonal Polygons with a Minimum Number of r-Stars
Introduction This paper presents an algorithm for covering orthogonal polygons with minimal number of guards. This idea examines the minimum number of guards for orthogonal simple polygons (without holes) for all scenarios and can also find a rectangular area for each guards. We consider the problem of covering orthogonal polygons with a minimum number of r-stars. In each orthogonal polygon P,...

متن کاملA New Heuristic Solution Method for Maximal Covering Location-Allocation Problem with M/M/1 Queueing System
We consider the queueing maximal covering location-allocation problem (QM-CLAP) with an M/M/1 queueing system. We propose a new solution procedure based on decomposition of the problem into smaller sub-problems. We solve the resulting sub-problems both with a branch and bound algorithm and with the meta-heuristic GRASP. We also solve the entire model with GRASP. Computational results for these ...
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 ...
