Capacitated Multi-Layer Network Design with Unsplittable Demands: Polyhedra
We consider the Capacitated Multi-Layer Network Design with Unsplittable demands (CMLND-U) problem. Given a two-layer network and a set of traffic demands, this problem consists in installing minimum cost capacities on the upper layer so that each demand is routed along a unique ”virtual” path (even using a unique capacity on each link) in this layer, and each installed capacity is in turn asso...
متن کاملA Simulated Annealing Algorithm for Unsplittable Capacitated Network Design
The Network Design Problem (NDP) is one of the important problems in combinatorial optimization. Among the network design problems, the Multicommodity Capacitated Network Design (MCND) problem has numerous applications in transportation, logistics, telecommunication, and production systems. The MCND problems with splittable flow variables are NP-hard, which means they require exponential time t...

متن کاملACO-Based Neighborhoods for Fixed-charge Capacitated Multi-commodity Network Design Problem
The fixed-charge Capacitated Multi-commodity Network Design (CMND) is a well-known problem of both practical and theoretical significance. Network design models represent a wide variety of planning and operation management issues in transportation telecommunication, logistics, production and distribution. In this paper, Ant Colony Optimization (ACO) based neighborhoods are proposed for CMND pro...
