| Research Abstract |
As one of the environmental requirements in European nations, we have formulated strip shelterwood management for natural regeneration in terms of spatially constrained harvest scheduling, and constructed the 0-1 integer programming model to resolve it. Our experiments showed that by reallocating harvesting strips over space and time subject to spatial requirements, we could reduce an impact of introducing the strip shelterwood management scheme. We have also constructed an optimization model to deal with aggregating individual forest stands spread over by different ownership, then applied the proposed model for an optimization problem subject to windstorm protection requirements, which demands harvesting toward the direction against wind.
