Products arranged in the same zone usually have some spatial correlation, function relation and the impact of environmental stress, which usually causes coupling effect with other products in the same zone. This kind of coupling effect affects products' quality, and may influence the veracity and comprehensiveness of the quality analysis. To solve this issue, starting from changing the traditional...
With the increase of equipment complexity, the probability of equipment failure is greatly increased. A wide range of engineering practice shows that the equipment investment in the different stages had a profound impact on the later maintenance costs. Therefore, it is very necessary maintainability to do maintenance optimal designing. But most of the existing maintainability design is a qualitative...
The real-time interaction between the user and virtual environment is now possible thanks to immersive virtual maintenance system, which greatly facilitates the maintainability design. At present, the methods to drive objects in virtual environment are mostly based on pose recognition, multi sensor or force, whose accuracy is not high enough, efficiency low and interaction unnatural. The development...
In this paper, a combined shock maintenance model is proposed for the deteriorating system, and the imperfect maintenance decision based on the replacement policy N is studied. This approach assumes that the system has two kinds of failure conditions, and the combined shock model is established by combining with the δ-shock model and accumulative shock model. The optimal replacement policy N is determined...
