A gamma distribution is used to model the material degradation. The degrading decrement after the imperfect maintenance action is assumed as a random variable normal distribution. This model aims to ob- tain the optimal maintenance policy and spare ordering point with the expected cost rate within system lifecycle as the optimization objective. The rationality and feasibility of the model are proved through a numerical example.展开更多

Firstly, the significance of talent training in marine cultural industry for the construction of China as a maritime power was analyzed. Secondly, the current situation of talent training in China＇s marine cultural industry and the existing problems were analyzed. Finally, how to integrate the collaborative innovation of governments, enterprises, colleges, scientific institutions and us-ers into the talent training system of marine cultural industry was explored to help talent training to break through the bottleneck and promote the vig-orous development of marine cultural industry.展开更多
