Proceedings of the Institution of Mechanical Engineers, Part O: Journal of Risk and Reliability 0 … WebBy using events which can be observed on a process, like maintenance events, the authors can predict failures before they occur and it is shown that Hidden Markov Models can be used according to a good choice of parameters. This paper deals with a tool which may help maintenance manager to schedule maintenance activities. To help him, we show that by …

WebThis synthetic model is intended to produce real industrial maintenance observations (or “symbols”), with a corresponding degradation indicator. These time series events are shown as Markov chains, also called “signatures”. The production of symbols is generated by using a uniform and a normal distribution. WebIn this paper, we wish to evaluate three Hidden Markov Models topologies of Vrignat et al. (2010), based on upstream industrial synthetic Hidden Markov Model. Our synthetic model gives us simulation such as real industrial Computerized Maintenance Management System. Evaluation is made by two statistical tests. green mountain wallpaper iphone
