Optimización de corte de varillas de acero de construcción

Abstract

The present research work uses mathematical modeling tools to improve the cutting building steel rods supported by Methodology of Operations Research. Also, this paper exposes the theoretical foundations described by several authors about operation research, functions, systems, formulations, etc., which have been applied during the development of this research to get the enough academic support to prepare this work correctly. Subsequently, a mathematical model to optimized Pure Integer Linear Programming type will be built in order to make cuts on standard size bars through defended parts, such that the smallest number of standard bars will be used, which impacts on waste reduction and helps save money. Furthermore, this model is based on the principle of One-Dimensional Cutting Patterns. After the modeling has been completed, the implementation of the model will be performed through the MATLAB software. The computer tool called LCO will allow to the optimization model of cutting steel rods to fit in many cases, helping not only to define what kind of standard size rod will be needed to purchase but also to indicate the optimal schemes or patterns for cutting the bars. Finally, due to the need to validate the model developed, the LCO program will be applied to a real case
