One of the basic questions facing transportation planners and road managers is how to provide and maintain a road system that provides efficient access to the forest while limiting adverse effects roads can have on water and soil resources. The purpose of this study is to develop decision support models...

Ignoring or delaying necessary maintenance can lead to damage that is more costly to repair than the original road construction. Good maintenance also helps ensure safety and necessary access, and it enhances the efficiency of vehicle and equipment travel over your property.
This research addresses the large-scale group fleet replacement problem with multiple vehicle types of multiple units, under budget and demand constraints. Past research in group fleet replacement is limited and has focused on one vehicle type, with multiples units and constraints. Many studies in fleet replacement have also dealt with...
This thesis is an attempt to develop a theoretical microeconomic
model which can be used to examine the short-run demand for the
timeliness of farm machinery repairs. This analysis focuses on
the timing of the repair after a breakdown has occurred.
The nonstochastic model developed allows the incorporation of
the...
The behavior of stirrups engaged by diagonal cracks and under service loads is
largely unknown. Full-size laboratory specimens were loaded to induce diagonal
cracks and subjected to high-cycle fatigue loading to represent a service life of 50
years. Tests indicated little change in the average stirrup stress range and mean...
