Abstract

Programs for a programable calculator and a desk-top computer are provided for quickly determining yarding cost and comparing the economics of alternative yarding systems. The programs emphasize the importance of the relationship between production rate and machine rate, which is the hourly cost of owning and operating yarding equipment. In addition to generating the data required for analyzing the cost of a yarding operation, the desk top program plots the yarding cost versus production rate curve. Examples and simple step-by-step operating procedures are included.
