RESUMO

The main area of an industrial layout is without no doubt the company, defining and integrating the productive elements. The main question is related to the right the place and arrangement of departments, cells or machines in a plant or clerical soil. Because of the geometrical and combinatorid aspects of the problem, it is a kind of question that solution can reach high levels of complexity, in accordance with the incremented in variables of the system. Moreover, the industrial layout embodies quantitative and qualitative factors that in association, can become difficult to analyze and model . The optimization is the process to find the best solution (or excellent solution) amon a set of solutions for a problem. The application of a optimization procedure exists . There is a particular set problems in which is decisive. They are complex problems, many times of difficult solution, and that they involve significant reductions of costs, improvements of times of processes, or one better allocation of resources in atividades.Os mathematical models they can be used to get the layout of more economic process, subject to restrictions that make possible the operation, maintenance and security. Therefore, all the models objectify to minimize the total cost, since that they around satisfy the restrictions of free space of the components. This category encloses the toillet papers, that answer for 80% of the production, the towels (16%) and nippes (4%), beyond the call "institucional line" for attendance the consumers biggest, as nets of fast-food, hospitals, offices, industries, etc. Brazil contributes with 3.1% of the world-wide production and is 8º producing world-wide of tissue paper. This work has as objective the use of the mathematical modeling for optimizing the position equipment in the manufacture paper of Tissue paper. The model used was based of (GUIRARDELLO, 1993) and the programming was made in Entire Mixing MILP, the software used for the modeling was the GAMS (General Algebraic Modeling System), which is assigned to the great construction and solution of and complex models of mathematical programming, offering powerful resources for programmers and being more understandable for users of models of others you discipline.
