- W2623401489 abstract "Frequent upgrades of equipments in the telecommunications industry occur due to the emergence of new services or technologic breakthroughs. In this work, we consider a network where each client is linked to a site and handled by a card located on that site. A technological migration has to be operated and it consists in replacing all the existing cards by cards of new generation within a fixed number of years. For practical considerations, all the cards of a site must be replaced on the same year. Furthermore, because of new offers, the number of clients per site is decreasing during the period. This enables us to reuse the new cards that are not used anymore once some clients have left. The optimization problem consists in deciding for each year, which sites are migrated and how many cards are bought or reused, in order to minimize the total cost. We present a formulation by integer linear programming and an exact solution for this problem." @default.
