Graduation date: The Timber Resource Analysis System (TRAS) was the\ud timber supply projection model used in conjunction with\ud the Timber Assessment Market Model (TAMM) to predict\ud future U.S. softwood timber harvests, inventories and\ud product prices in the RPA Timber . Updates and adds instructions for volume estimators, adds reference to FSH a, Timber Volume Estimators Handbook. Adds definitions of statistical terms. Adds example calculations of cruise statistics.

The model derived to explain historical timber sale prices, and to predict future sale revenue is as follows: (1) Revenue i = exp b 0 + b 1 ln T S V i + b 2 ln T P V i + b 3 ln S V P A i + b 4 ln S V P T i + b 5 ln P P I R i where Revenue i. is revenue, in thousands of dollars, from timber sale i; TSV i. is total pine sawtimber volume Cited by: 2. The text provides literature surveys on relevant modeling issues and policy concerns, and demonstrates the application of the modeling system using a "base case" 50 year projection . Types of yield prediction models. A yield prediction model uses the quantitative relationships between measured growth variables to predict yields of forest types, and is a tool that helps to schedule and regulate harvests at sustainable levels. Two basic methods are available for their construction, diameter class (or stand table) projection . Books at Amazon.

  Model structure. Out of the 27 plots, 5 plots, on which illegal logging had been detected, were excluded from the analysis. The dynamic growth model developed from these data is based on the state-space approach and it is similar to those of García (), García et al. and García ().In this model Cited by: CHAPTER 2 QUANTITY TAKE-OFF The quantity “takeoff” is an important part of the cost estimate. It must be as accurate as possible and should be based on all available engineering File Size: 1MB.
