Time-and-motion studies were conducted on four contract logging operations in north Louisiana to develop input parameters for the felling, skidding, loading, and transportation simulator (FSLAT). FSLAT was then used to simulate the harvest of 16 stands of various haul distances for four different contractors. A data base of 320 observations was constructed from the projected logging costs, stand variables, and haul distances. A step-wise variable selection package was used to select the best combination of variables for an equation to predict logging costs. The best equation, based on 1982 equipment and fuel costs, exclusive of profit, is: [equation] A fifth operation was studied for verification purposes. The equation predicted within 0.3 percent of the actual cost.
