Abstract

This paper presents a model for rural road network design that involves two objectives: maximize all season

road connectivity among villages in a region and maximize route efficiency, while allocating a fix budget among

a number of possible road projects. The problem is modeled as a bicriterion optimization problem and solved

heuristically through a greedy randomized adaptive search procedure (GRASP) in conjunction with a path relinking

procedure. The implementation of GRASP and path relinking includes two novel modifications, a new form of

reactive GRASP and a new form of path relinking. Overall, the heuristic approach is streamlined through the

incorporation of advanced network flow reoptimization techniques. Results indicate that this implementation

outperforms both GRASP as well as a straightforward form of GRASP with path relinking. For small problem

instances, for which optimality could be verified, this new, modified form of GRASP with path relinking solved

all but one known instance optimally.
