PHM (Prognostics and Health Management) is an engineering technology focusing on failure prognostics and so it has critical effects on the performance of the task system. In this paper, the qualitative analysis method of FMEA (Failure Mode and Effects Analysis) is proposed to analyze the prognostics' performance of PHM system and five corresponding evaluation parameters are derived. Based on some...
In this article, we proposed a MARI&A model for single-unit and two-unit system maintenance. The model is combinations of arithmetic reduction of failure intensity and virtual age, which can be apply to continuous operating system with corrective maintenance and preventive maintenance during its maintenance process. Failure interactions and maintenance interactions among units are also taken into...
Support equipment is indispensable in the maintenance support process. Its allocation including what kind of support equipment and how many for each of them to be equipped determines whether relevant maintenance support tasks can be started and finished timely and effectively at maintenance support stations, and has a huge influence on the support system's cost, footprint and versatility. So far,...
