Resumo: | The main objective of this work was to evaluate the consequences of the use of yield and growth estimates from different prediction yield and growth models in a Linear Programming model applied to forest regulation. Thus, using data of continuous forest inventory, the yield estimation in future volume was obtained using a yield model based on age, another one based on age and site index, and a third model that used age and site index besides density, which was represented by the basal area per hectare. Also a model based on data of continuous forest inventory which uses data of volume on a period of time to make linear projections of yield for the next period was tested. Next, a simplified forest regulation problem was proposed and solved by the model I by means of Linear Programming, using data from the four volume prediction models. At the end, the conclusion was: a) that models of forest regulation, supplied with estimates from different yield models, when solved by Linear Programming, result in different ways of treating the forests; b) that the matrix of technological coefficients, supplied with different yield data and for a same objective function affects in a significant way the decision making process. |

Assim, utilizando dados de um inventário florestal contínuo, obtiveram-se diferentes estimativas da produção futura em volume, pelo ajuste de um modelo de produção em função da idade, outro em função da idade e do índice de local e por um terceiro modelo que incluiu, além da idade e do índice de local, a densidade, representada pela área basal por hectare. Testou-se também um modelo baseado nos dados de inventário florestal contínuo que utiliza os dados de volume de um período para fazer projeções lineares da produção para o período seguinte. Em seguida, um problema de regulação florestal simplificado foi idealizado e resolvido pelo modelo I por meio de Programação Linear, utilizando dados oriundos dos quatro modelos de predição do volume. Ao final, concluiu-se: a) que modelos de regulação florestal, alimentados por estimativas provenientes de diferentes modelos de produção, quando resolvidos por Programação Linear, resultam em diferentes maneiras de se conduzir a floresta; b) que a matriz de coeficientes tecnológicos, alimentada por diferentes dados de produção e para uma mesma função objetivo, afeta, de maneira significativa, o processo de tomada de decisão.Universidade Federal de Santa Maria2005-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/172410.5902/198050981724Ciência Florestal; Vol. 13 No. 1 (2003); 57-72Ciência Florestal; v. 13 n. 1 (2003); 57-721980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1724/993Silva, Gilson Fernandes daLeite, Helio GarciaSoares, Carlos Pedro BoechatSilva, Márcio Lopes dainfo:eu-repo/semantics/openAccess2017-05-19T17:07:10Zoai:ojs.pkp.sfu.ca:article/1724Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-19T17:07:10Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
