Hello, I am looking for someone to write an essay on System Health Prognostics. It needs to be at least 4750 words.This kind of analytical finding or system health prognostics are motivated by the requirement for manufacturers and other operators of complex systems for improving performance of equipment and reducing costs of maintenance and surprise failure of equipment. Health system prognostics are difficult tasks requiring accurate, adaptive and instinctive models to forecast future machine health states. A number of modelling procedures have been suggested in the literature and put into practice. This paper will discuss how to apply available methods to a practical problem. The paper will also review the ideas and procedures that focus on improving dependability and reducing sudden failure by monitoring and forecasting machine health. The Introduction of the paper will give general view of maintenance strategies. The other sections will discuss tools and techniques of maintenance strategies. A vital part of the examination is analyzing effective ways of assessing the output of system health prognostics because at present there are no unanimously accepted techniques. It is explained that the model outputs can be used to forecast effectively whether the system health prognostics was employed within a given implementation of the simulation model. ‘Fix it when it is broken’ is an old and most common maintenance and repair strategy. This approach is prevalent among firms, costing them potentially millions of dollar every year. According to this approach, no analysis or planning is required for the maintenance.
