From preventive maintenance programs to predictive condition monitoring solutions based on the latest technologies – cogeneration plants and windfarms. The corresponding bivariate optimization problem is considered and illustrated by detailed numerical examples.

More recently, ‘predictive maintenance’ is being employed, which uses sensor data to monitor a system, then continuously evaluates it against historical trends to predict failure before it occurs. Over time, the terminology of MRO has begun to become standardized. OEM includes any activity related to the direct manufacture of goods, where MRO refers to any maintenance, repair or overhaul activity to keep a manufacturing plant or facility running. Maintenance is strictly connected to the stage of ideation, in which the concept of maintainability must be included. In this scenario, maintainability is considered as the ability of an item, under stated conditions of use, to be retained in or restored to a state in which it can perform its required functions, using prescribed procedures and resources. Over time corrective maintenance gained the support of preventative maintenance.
New technologies are continuing to expand the scope of the field. Predictive maintenance, which uses sensor data to monitor a system, then continuously evaluates it against historical trends to predict failure before it occurs. MRO to preserve, rehabilitate, restore, or reconstruct historical structures with stone, brick, glass, metal, and wood which match the original constituent materials where possible, or with suitable polymer technologies when not. Preventive maintenance is maintenance performed with the intent of avoiding failures, safety violations, unnecessary production costs and losses, and to conserve original materials of fabrication. More recently, advances in sensing and computing technology have given rise to ‘predictive maintenance’. This maintenance strategy uses sensors to monitor key parameters within a machine or system, and uses this data in conjunction with analysed historical trends to continuously evaluate the system health and predict a breakdown before it happens.
This strategy allows maintenance to be performed more efficiently, since more up-to-date data is obtained about how close the product is to failure. All actions which have the objective of retaining or restoring an item in or to a state in which it can perform its required function. The actions include the combination of all technical and corresponding administrative, managerial, and supervision actions. AAP-6 – Glossary of terms and definitions”.

It is a software application addressed to the diagnosis in real-time of industrial processes. It takes into account the information coming in real-time from different sensors and other information sources and tries to detect possible anomalies in the normal behaviour expected of the industrial components. The incipient detection of anomalies allows for an early diagnosis and the possibility to plan effective maintenance actions.
Also, the continuous monitoring performed allows for an estimation in a qualitative form of the health condition of the components. SIMAP is a general tool oriented to the diagnosis and maintenance of industrial processes, however the first experience of its application has been at a windfarm. In this real case, SIMAP is able to optimize and to dynamically adapt a maintenance calendar for a monitored windturbine according to the real needs and operating life of it as well as other technical and economical criteria. In particular this paper presents the application of SIMAP to the health condition monitoring of a windturbine gearbox as an example of its capabilities and main features.

He divides his time between teaching and research in the artificial intelligence field applied to diagnosis and maintenance of industrial processes. He has been the main researcher in more than 35 industrial projects over the last 20 years related to the diagnosis in real-time of industrial processes, incipient detection of anomalies based on models, knowledge acquisition and representation, reliability and predictive maintenance. All these projects have been based on a combination of artificial intelligence, new information technologies and data mining techniques. PhD in industrial engineering at University Pontificia Comillas, Spain. She worked at National Grid Company, UK, in 1997, developing a real-time monitoring and analysis system of the electrical network stability and robustness.
Her PhD thesis was related to the planning and effectiveness assessment of predictive maintenance applied to industrial processes, using for that purpose dynamic modelling techniques as well as artificial intelligence. In 2004, she joined the Spanish Savings Bank Caja Madrid, working in a research project for developing real-time automatic trading systems for fixed income futures, equity and forex products. These trading systems use neural networks, quantitative and technical analysis techniques. Currently, she is a quantitative credit analyst at BSCH. Her areas of interest are: artificial intelligence, data mining, quantitative techniques applied to financial markets, process modelling and signal processing techniques. University of Zaragoza in Spain. During his years of engineering studies, he worked at various different power plants.
At present, he is the Director of the energy area of SAMCA, a Spanish company working in different industrial sectors including energy generation. He has participated in the development of several projects concerning the optimization of processes, cogeneration plants and windfarms. Un article de Wikipédia, l’encyclopédie libre.
