We use a decomposition approach to solve two types of realistic problems: block-angular linear programs arising in energy planning, and multicommodity network problems arising in capacity planning for survvable telecommunication netwroks. Decomposition is an algorithmic device that breaks down...

This paper presents a new primal-dual algorithm for solving a class of monotropic programming problems. This class involves many problems arising in a number of important applications in telecommunications networks, transportation and water distribution. The proposed algorithm is inspired by...

Un choix ECI s'appuie encore aujourd'hui sur des analyses d'opportunites considerant l'entreprise comme une entite isolee. Or, l'EDI interesse des reseaux de "partenaires" dont certaines societes pourraient avoir des specificites communes. L'objet de notre etude est de determiner ces criteres...

In this paper, we discuss the optimal design of telecommunications networks prone to failure. The problem concerns mid-range planning objectives. The purpose of the model is to give insight on the cost of protecting the network against failures by balancing the choice of a base routing of the...

Participation in a strategic network constitutes a radical departure from formerly prevalent modes of organizing which requires a change of 'theories-in-use' associated with independent operations. The transition process between these cognitive constructs associated with 'old' organizational...

This paper deals with the sizing of telecommunications networks offering private line service to a few clients. The clients ask for some transfer capacity between some pair of nodes, but their demand is uncertain. In case of high demand and insufficient capacity, some clients may be denied the...
