Abstract

This paper focuses on optimizing multi-period investment strategies for Fiber deployment. The main objective is to provide guidelines to improve the cost-effectiveness of Fiber investment strategies employed by telecommunication operators. To achieve this objective, an optimization framework is developed, providing a systematic approach to multi-period investment planning for Fiber deployment. It combines mathematical modeling and data analysis. For this, we introduce two mixed-integer linear programs to formulate the problem, taking into account demands, budget constraints and market conditions. Additionally, we propose several valid inequalities for the associated polytopes to enhance the linear relaxation and achieve tighter bounds. Relying on this modeling framework, we devise an exact optimization approach based on a Branch-and-Cut algorithm to solve the problem. Furthermore, we present a computational study that considers various instances and scenarios to assess the performance of the proposed models and algorithms.
