Maintenance Practice Performance Assessment of Hydraulic Machinery: West Balkan Meta-Statistics and Energy-Based Maintenance Paradigm

As a consequence of accepting the Green Deal initiative, sustainable maintenance attracted significant attention. However, observation of low market intelligence and lack of sustainable goal-oriented practice has been reported. The article proposes the Energy-Based Maintenance (EBM) paradigm to fulfil the needs of sustainable manufacturing philosophy. The EBM implicitly consists of two concepts: Functional Productiveness (FPC) and Comparative Functional Dynamics (CFD). Namely, the core of FPC is to propose a new view in understanding the nature of functionality by delineating static (maintenance) events (e.g., total failure, stoppage, etc.) from dynamic (process) events (e.g., quasi-faults, leakage, degradation). The CFD uses FPC and dynamic (process) events and acts as a catalyst in reducing noise in feature extraction by comparing system dynamics and energy consumption. Demonstration on a case study of proposed EBM practice is conducted and used as a measure of comparison with traditional maintenance practices (policies). However, the results show a reduction in oil waste and energy consumption at the cost of increasing inspection and stoppages. © 2021 IEEE.
