Designing low-cost networks that survive certain failure situations is one of the prime tasks in the telecommunication industry. In this paper we survey the development of models for network survivability used in practice in the last ten years. We show how algorithms integrating polyhedral combinatorics, linear programming, and various heuristic ideas can… (More)

Given a communication demand between each pair of nodes of a network, we consider the problem of deciding what capacity to install on each edge of the network in order to minimize the building cost of the network and to satisfy a given demand between each pair of nodes. The feasible capacities that can be leased from a network provider are of a particu lar… (More)

Designing low cost networks that survive certain failure situations belongs to one of the prime tasks in the telecommunications industry. In this paper we describe a mathematical model integrating several aspects of survivability that are elsewhere treated in a hierarchical fashion. We present mathematical investigations of this model, a cutting plane… (More)

This paper discusses the creation of an Agent-Based Simulation that modeled the introduction of care coordination capabilities into a complex system of care for patients with Serious and Persistent Mental Illness. The model describes the engagement between patients and the medical, social and criminal justice services they interact with in a complex… (More)
