Abstract The Capacitated m-ring-star Problem is a variant of the classical one-depot capaci-tated vehicle routing problem in which a customer is either on a route or is connected to another customer or to some(More)
In this work we introduce profit-oriented capacitated ring ar-borescence problems and present exact and heuristic algorithms. These combinatorial network design problems ask for optimized bi-level networks taking into account arc costs and node profits. Solutions combine circuits on the inner level with arborescences on the outer level of the networks. We(More)
