Abstract
The work arises upon a long-lasting relationship between Tim S.p.A. and the Politecnico di Torino, aimed at developing an intelligent alarm management system capable to handle all network failures rising along the national territory and cluster them based on causal correlation. Indeed, the company is currently detecting all failures at a single-device granularity, lacking therefore an high-level partitioning linking causally-correlated alarms which would help TIM S.p.A. in quickly identifying the problem and operating accordingly. As of now, clustering is performed following ad hoc heuristics which, while presenting comforting results, are still only slightly validated by TIM S.p.A. domain experts due to the time-consuming process required.
This thesis is intended as a parallel approach to the one currently adopted – based on a sounder mathematical foundations – with the goal of not only providing a promising new method, but also a possible validation of the heuristics in use
