Incorporating Energy Efficiency in the Definition of Maintenance Strategy: Bibliometric Analysis and Road Mapping

Ever-evolving energy market landscape together with higher attention towards environmental sustainability, is leading manufacturing companies to reshape and re-evaluate their internal processes so to favour a more energy-efficient management of productions systems. In light of this, being maintenance one of the main contributors to this goal, the introduction of energy within the maintenance strategy definition process may change the final outcome by balancing costs and production lost with energy-related performance. Therefore, this research aims at investigating how energy is currently incorporated into the maintenance strategy definition by carrying out a bibliometric study. Grounded on the results, the process for energy-efficient maintenance strategy definition can be decomposed into data input, energy-related indicators modelling and finally the maintenance strategy definition. Scientific literature confirmed that barriers and challenges are still present to exploit envisioned benefits of introducing energy while defining maintenance strategies. For this reason, this work identifies a roadmap to embed energy into maintenance strategy definition by increasing the complexity in terms of asset behavioural modelling, energy indicators modelling and achievable benefits.
