Fixed-Charge Network Design Problemse distinguish whether the demand can be represented as a single commodity or as multiple commodities, whether or not there are capacities, and whether or not there are variable transportation costs in the objective function, in addition to the fixed design costs. These characteristics yield differen

Exact Methods for Fixed-Charge Network Designicult, since they are in general strongly .-hard. In addition, their objective function includes both fixed design costs and variable transportation costs, which results in complex tradeoffs that complicate the task of finding optimal solutions. Multicommodity capacitated fixed-charge problems are p

Heuristics and Metaheuristics for Fixed-Charge Network Designf heuristic approaches, such as search spaces, neighborhoods, and populations of solutions. The main heuristic and metaheuristic solution methods are then introduced: constructive and Local Search heuristics, neighborhood-based metaheuristics, population-based methods, matheuristics, parallel meta-

Topology-Constrained Network Designjective is to build a network at minimum cost, considering only the fixed cost associated with opening a link. Capacity and routing costs are therefore ignored. Nevertheless, the network is subject to topological constraints to ensure its connectivity and survivability. We cover the design of connec

Network Design with Routing Requirementsto meet all demand at total fixed and flow costs, subject to additional constraints on routing decisions to ensure good end-to-end service performance. For instance, in settings such as package delivery, rail freight operations, vehicle routing, and crew scheduling, these service requirements includ
