Abstract
A method and system for merging health indicators of a device. During the method, health indicators Indi are firstly distributed in at least one indicator group G, each health indicator Indi being associated with a respective detection threshold Sdi, it being possible to determine a characteristic operating point of the device by using the health indicators Indi of an indicator group G. An alarm threshold Sa is determined using training health indicators. Then, a merged health indicator MHI is determined by taking into account both of the alarm threshold Sa and also of the detection thresholds Sdi of the health indicators Indi of the group G. Finally, the merged health indicator MHI is compared to the alarm threshold Sa and it is deduced whether or not the device presents a fault or a risk of such a fault appearing.
