Timber Management Planning with Timber RAM and Goal Programming
By using goal programming to enhance the linear programming of Timber RAM, multiple decision criteria were incorporated in the timber management planning of a National Forest in the southeastern United States. Combining linear and goal programming capitalizes on the advantages of the two techniques and produces operationally feasible solutions. This enhancement may also be applicable to linear ...
متن کاملTimber Cycles *
We construct an intertemporal model of rent-maximizing behaviour on the part of a timber harvester under potentially multi-dimensional risk as well as geographical heterogeneity. Subsequently, we use recursive methods (in particular, the method of dynamic programming) to characterize the optimal policy function, the rent-maximizing timber-harvesting profile. One noteworthy feature of our applic...
متن کاملThe Semantic Layers of Timber
We present a three-layered semantics of Timber, a language designed for programming real-time systems in a reactive, object-oriented style. The innermost layer amounts to a traditional deterministic, pure, functional language, around which we formulate a middle layer of concurrent objects, in terms of a monadic transition semantics. The outermost layer, where the language is married to deadline...
متن کاملAppropriateness of probit-9 in the development of quarantine treatments for timber and timber commodities.
Following the increasing international phasing out of methyl bromide for quarantine purposes, the development of alternative treatments for timber pests becomes imperative. The international accreditation of new quarantine treatments requires verification standards that give confidence in the effectiveness of a treatment. Probit-9 mortality is a standard for treatment effectiveness that has its...
متن کاملTimber Regulation and Value Chain in Community-Based Timber Enterprise and Smallholder Forestry in the Philippines
Forest tenure reform has no doubt attained significant gains in promoting social justice and equity in the forest sector, through legal recognition of the communities’ property rights over forest lands in many developing countries. This includes the right to harvest and market trees that the communities planted. Along these lines, the Philippines’ community-based forest management (CBFM) and sm...
