Kyushu Electric Power Co., Inc. is carrying on a project that handles from silviculture and harvesting to house building in order to make more profit in this severe situation for foresters. In this paper, as a basic research suggesting the optimal stand management plan to produce timber agreeing the buyers’ intention, we produced an optimal stand management model producing woodbased materials in the forest of Kyushu Electric Power Co., Inc. as an example. The method is generally similar to a forest stand optimization model called DP-KYSS within the dynamic programming framework. We improved it that we could consider more detail about the purpose of this research. In the result, the profit (as SEV: soil expectation value) increased about 1.2 times compared with the present plan. However we have some problems, for example, the impracticality in the plan and the algorithmic instability.
