Este estudo foi realizado na Indústria Pedro N. Pizzatto, municÃpio de General Carneiro, Paraná e objetivou-se
modelar o planejamento florestal através da programação em metas (Goal Programming), considerando o estoque de carbono
existente nas florestas. Utilizou-se o Software SISPINUS para prognosticar o volume, a altura e o diâmetro de 11 projetos
submetidos a 5 diferentes regimes de manejo, considerando 21 anos e a quantidade de carbono remanescente e retirado. De posse
dos resultados encontrados pelo SISPINUS estabeleceram-se metas para a variável carbono, metas econômicas (baseada no
faturamento anual da empresa) e metas de demanda para cada sortimento. As metas de carbono e de demanda foram definidas a
partir dos valores encontrados para o melhor resultado do horizonte de planejamento. As metas estabelecidas não foram atingidas,
indicando que as mesmas foram muito ambiciosas para a situação encontrada nesse estudo e não que os modelos não sejam
considerados indicados para o caso.
This study was carried out in the Pedro N. Pizzatto industry, located at General Carneiro county, in the State of Paraná.
The objective was to develop a planning model using goal programming, taking into consideration carbon stock in the forests under
different management regimes. The data were obtained from 11 stands and the SISPINUS growth and yield simulator was used to
predict volume, mean tree height and dbh of these stands managed under five different options for a planning horizon of 21 years and
the removed and remaining carbon stocks. From the results provided by SISPINUS, carbon stock goals, economic goals (based upon
the annual income of the company) and demand goals for each log use (assortment) were established. The carbon and demand goals
were defined for the best previously selected scenario. The established goals were not attained. This result indicated that the defined
goals were too ambitious to be accomplished, however, the models are considered suitable to be used in such case.
