Abstract: In this paper, we present a new method based on Network Analysis for implementing what we called Sensorless Predictive Maintenance (PdM) on production lines of coffee machines of an Italian manufacturing company, Nuova Simonelli S.p.A.. To the best of our knowledge, such an approach is an innovative one in the field of PdM; its final goal is to implement a way for performing PdM without installing sensors on machines or production lines. The results are very promising and allow us to gain knowledge about the assembly process after it took place. Then, such knowledge can be used for improving the process and putting into practice the Sensorless PdM on the new coffee machines.
