Abstract

The Weak Link hand-held calculator program (HP-41C) quickly analyzes a system for logging production and costs. The production equations model conventional chain saw, skidder, loader, and tandemaxle truck operations in eastern mountain areas. Production of each function of the logging system may be determined so that the system may be balanced for minimum cost. The user supplies input data, and the program calculates cost rates for the various functions of logging. The final output is logging costs in dollars per M bf (thousand board feet).
