Aplicação de Goal programming em um problema florestal

Abstract

The objective of this paper is to apply one of the techniques of multi -objective programming (goal programming) in a Brazilian forest problem, through of a case study accomplished in the Sant a Câ ndida Farm, in General Carneiro, Paraná, Brazil. The areas of this farm can be managed for timber (pine and native species), harvesting of erva-mate leaves, pasture, and tourism. There is also a concern of the farm managers with increasing the diversity of flora and fauna, increasing environmental protection conditions and maintaining employees in the farm. Goal programming was used to develop a project of land allocation, in which all the goals would be reached as closest as possible of the ideal, in a way to attend all the operational restrictions considered. In goal programming, the concept of optimum solution of LP problems is substituted by a satisfactory solution (nondominated). Several solutions can be obtained, and the best solution will depend on the priority associated to each goal.
