AbstractFIDME-PC was developed to aid forest managers to evaluate arid screen out investment alternatives with relative ease and great precision. Up to four investment alternatives may be compared using any one of the four economic criteria: 1) cost effectiveness, 2) benefit-cost ratio, 3) present net worth, and 4) internal rate of return. The input estimates for the model may be expressed in the form of either point of subjective probability estimates. Simulated results will provide the probability that one investment might differ from others. Therefore, the forest manager will be able to choose, with a known degree of confidence, between investment alternatives. Model applications are demonstrated by examples.
