Summary : A linear programming model was developed to solve simultaneously the cut scheduling problems in forest plantations and was applied to a hypothetical forest (using cost information from Paper Industries Corporation of the Philippines (PICOP) and Nasipit Lumber Company, Inc. (NALCO) in which the objective of management is to maximize the net worth of the existing and proposed Albizia falcataria plantations. Using a planning horizon of 46 years, the model included 2,325 decision variables and 480 constraining equations. For a given demand level, the model was run in the National Computer Center (NCC) and the optimal solution was obtained after 277 iterations. The model was also run using different levels of demand.
