Résumé : | The Lagrange multiplier method was applied for estimating the forest volume at minimum cost by plot-double sampling. A composite cost function was used which has also included the walking cost of the second-phase sample. Compared to the plot sampling the error was increased per 10,45 percent and the cost decreased per 7,35 percent. When the volume measurement cost is increased a significant decrease of the total cost of the plot-double against plot sampling is observed |
