Predictive maintenance: spend a little to save a lot
Paolo Carnovale, Head of Industrial Product Marketing, RS Components Spending money to save money doesn’t come easy to some. But in the case of predictive and preventative maintenance regimes – especially for high-capital assets – a relatively modest spend could potentially offset repair or lost-production costs that run into millions. The problem with maintenance spend is that it is very hard to quantify its benefits if nothing actually goes wrong – accountants tend to like tangible figures as opposed to those generated by “what-if” scenarios. Couple this to budget competition from other disciplines and the job of justifying the expenditure becomes even harder. As it is tough to define an “opportunity cost/loss” in terms of maintenance statistically, it is far easier to look at the issues simplistically by determining, for example, the cost of maintenance vs. the cost of repair/replacement and the expected life of a machine or asset vs. its extended service life. In all cases, the cost of lost production, goodwill and customer confidence must also be factored in to this equation. Even with these simple analyses, the need to have maintenance as a strategic element of an operational plan, becomes very clear, but what is the next logical step? For those with complex operations, the obvious route is the deployment of a computerised maintenance management system (CMMS), which will help remove much of the guesswork and workload by defining a strategy and timetable as well as the actual work to be undertaken on individual machines and assets. More often than not, this type of proactive approach is combined with technological solutions that offer a real-time snapshot of machine health. These solutions range from simple temperature sensors and vibration probes all the way up to bespoke, fully featured condition monitoring (CMS) software solutions. How they are selected, […]
