In this paper we propose a heuristic method to solve the Capacitated m-Ring-Star Problem which has many practical applications in communication networks. The problem consists of finding m rings (simple cycles) visiting a central depot, a subset of customers and a subset of potential (Steiner)...

This volume offers a survey of the most important current research in mathematical modelling for transportation analysis with particular emphasis on transportation planning, transportation management and vehicle management. In particular, the reader will find models, solution algorithms and...
