Description

capacity assignment problem

given:

  • assigned flow value of each link
  • traffic demand between each pair of nodes

objective:

  • determine the optimal capacities of each link

flow assignment problem

given:

  • capacities of each link
  • traffic demand between each pair of nodes

objective:

  • determine the optimal assignment of flow on each link

combined capacity and flow assignment problem

given:

  • traffic demand between each pair of nodes

objective:

  • determine the optimal capacities of each link
  • determine the optimal assignment of flow on each link

Heuristic Algorithms For Capacity and/or Flow Assignment

  • branch exchange algorithm
  • cut saturation algorithm
  • routing with economies of scale
