车险费率市场化改革近在眼前 或带来车险行业三大变革

我国车险市场长期存在着销售误导、骗保等机构违规行为。车险条款也存在着无责不赔、高保低赔、不合理免责条款等霸王条款。同时,车险行业还存在理赔流程复杂、理赔速度慢等行业痼疾。这些都侵犯了车主的合法权益,并给车主的投保、理赔等带来诸多不便。车险费率的两轮改革相对于其它险种,我国车险的费率市场化改革起步较早。但始

Bayesian reliability assessment and degradation modeling with calibrations and random failure threshold

A degradation model with a random failure threshold is presented for the assessment of reliability by the Bayesian approach. This model is different from others in that the degradation process is proceeding under pre-specified periodical calibrations. And here a random threshold distribution instead of a constant threshold which is difficult to determine in practice is used. The system reliability is defined as the probability that the degradation signals do not exceed the random threshold. Based on the posterior distribution estimates of degradation performance, two models for Bayesian reliability assessments are presented in terms of the degradation performance and the distribution of random failure threshold. The methods proposed in this paper are very useful and practical for multi-stage system with uncertain failure threshold. This study perfects the degradation modeling approaches and plays an important role in the remaining useful life estimation and maintenance decision making.
