Road network optimization using heuristic and linear programming
cable yarding mixed integer programming network analysis optimum road density production
2015/3/20
To minimize the cost of logging, it is necessary to optimize the road density. The aim of this study was to determine optimal road spacing (ORS) in Northern Austria. The stepwise regression method was...
A mathematical programming approach to crop mix problem
Crop mix single-harvest linear programming
2011/2/22
Problems normally faced by farmers include what to plant, how much to plant and when to plant. In this study, a linear programming crop mix model for a finite-time planning horizon was proposed. Given...
