Transmission expansion planning with re-design has been recently proposed in the literature to improve on the classical transmission expansion planning by allowing to cut-off circuits while expanding the network. Although the reductions in the solution costs are significant, the resulting mixed-integer linear programming formulations are very difficult to(More)
This paper presents an iterated local search for the fixed-charge uncapacitated network design problem with user-optimal flow (FCNDP-UOF), which concerns routing multiple commodities from its origin to its destination by designing a network through selecting arcs, with an objective of minimizing the sum of the fixed costs of the selected arcs plus the sum(More)
We study a multivehicle inventory routing problem (MIRP) in which supplier delivers one type of product along a finite planning horizon, using a homogeneous fleet of vehicles. The main objective is to minimize the total cost of storage and transportation. In order to solve MIRP, we propose an algorithm based on iterated local search (ILS) metaheuristic,(More)
