The main objective of this work was to evaluate, through Integer Programming, the consequences of using Linear Programming with post rounding out of the responses, with emphasis on even-aged forest regulation. Thus, a simplified forest regulation problem was proposed out and solved by model I by means of Linear Programming, Linear Programming with post rounding out, and Integer Programming. It was concluded that the rounding out of responses obtained by the model solved by Linear Programming led to an unviable solution for the proposed regulation problem. The same did not occur with the Integer Programming model, which presented a viable, optimal regulation plan, showing that, from a mathematical viewpoint, responses with rounding out of solution using Linear Programming models should not be adopted.
