We consider the node clustering problem that arises in designing a survivable two-level telecommunication network. The problem simultaneously determines an optimal partitioning of the whole network into clusters (local networks) and hub locations in each cluster. Intercluster traffic...

This paper provides a proof of the symmetrical allocation property (SAP), conjectured in an earlier work on the workload allocation problem for a manufacturing flow line system. The system consists of N single-Erlang servers in series having a common interstation buffer capacity. SAP says a...

We consider the bandwidth packing problem arising from telecommunication networks. The problem is to determine the set of calls and an assignment of them to the paths in an arc-capacitated network to maximize profit. We propose an algorithm to solve the integer programming formulation of the...
