Predictive maintenance based on smart monitoring and data analytics

This paper discusses recent world progresses in smart monitoring and data analytics that have enabled predictive maintenance (PdM) of infrastructures; however currently the industry is slow in employing new smart monitoring sensors, information technologies, and data analytics for achieving PdM. PdM is data-driven and relies on smart monitoring and data analytics insights for maintenance, protection and repairs ahead of disruptions in operation. PdM is considered to be a new industry trend and has progressed rapidly in the industrial world since the 1990s; however our recent survey of the industry has shown that its application in infrastructure maintenance is very limited. This paper also discusses briefly recent progresses in PdM enabling technologies including corrosion monitoring probes, information technology platforms, data analytics and internet-of-things.
