The operations and maintenance of a wind farm constitutes a considerable source of expenditures therefore a holistic framework is herein presented aiming at optimising their management. The principles upon which the framework was developed belongs to the asset management discipline oriented towards the wind energy sector. Besides, it is understood from a cross functional perspective which also embraces information management and business aspects. The framework comprehends different modules conceived with the following purposes: (i) creation of an integral and comprehensive failure database, (ii) modelling of the wind turbines’ reliability taking into account their operational context and (iii) defining of maintenance strategy within a life-cycle perspective. The practical aspects of the framework are demonstrated through a case study based on real-field data from the sector. Furthermore, the present research sets the foundation to consider all the proposed algorithms, processes and techniques within a Product-Service System approach, which entails important benefits for the OEMs an for the operators.

In recent years, the concept of Industry 4.0 has been significantly advanced in industrial circles as an aspect that provides a competitive differential. Through the technologies involved, machines can now monitor and relay information on their operating conditions for analysis and decision-making, as well as for prompting action. These new functions generally involve the development of technological projects and significant investments. This renders it expedient to explain why certain systems should be monitored, but not others, as well as the use to be given to the data gathered as a way of generating income for a firm. This approach is especially important in certain corporate operations, such as after-sales maintenance. This article introduces a reference framework that permits the effective and efficient management of after-sales maintenance services. This framework relates after-sales service technologies with product technologies (Industry 4.0), and therefore covers the reasons and purposes of Industry 4.0 within the ambit of after-sales service.
