DFSIM (Douglas-Fir Simulator) with Economics: A Financial Analysis Option for the DFSIM Douglas-Fir Simulator

摘要

A modified version of the DFSIM Douglas-fir (Pseudotsuga menziesii) growth and yield simulator FDSIM with economics, now has an economics option that allows the user to estimate present net worth at the same time a silvicultral regime is simulated. If desired, the economics option will apply a volume adjustment multiplier in yields used in the analysis to reflect application of small-plot research results to average operating conditions or to account for genetics or other local conditions. It can also account for salvage of mortality. Prices can be entered as a table of values or as an equation that can vary with diameter. Logging costs can be entered as a table or can be generated internally for a short-span cable system.
