We estimate the management plan of a government-owned forest. Using goal programming method and dynamic linear programming method, we solve the dynamic problem that involves conflicting aims of profitability and protection among different periods. In sections 2 and 3, we briefly consider ‘sustainable development’ for forest. In section 4, 5, 6 and 7, programming model for forest management is proposed. In section 8, we estimate the possibility of improvement for government-owned forest management.
