Query: Disaggregated Benders decomposition and lazy constraints for solving the
  budget-constrained dynamic uncapacitated facility location and network design
  problem   We present an approach for solving to optimality the budget-constrained
Dynamic Uncapacitated Facility Location and Network Design problem (DUFLNDP).
This is a problem where a network must be constructed or expanded and
facilities placed in the network, subject to a budget, in order to satisfy a
number of demands. With the demands satisfied, the objective is to minimise the
running cost of the network and the cost of moving demands to facilities. The
problem can be disaggregated over two different sets simultaneously, leading to
many smaller models which can be solved more easily. Using disaggregated
Benders decomposition and lazy constraints, we solve many instances to
optimality that have not previously been solved. We use an analytic procedure
to generate Benders optimality cuts which are provably Pareto-optimal.
