摘要

在系统可靠性预测方法中,通常假设各部件的故障过程是独立的、不相关的,不受其他部件的影响。然而,在产品的实际工作过程中,由于产品各部件之间的动态影响而造成的寿命变化不容忽视。提出了一种基于模糊认知图的可靠性预测方法,并以系统级封装(SiP)为例,研究了系统级封装各部件在动态相互影响状态下的寿命预测问题。

Research on a Reliability Prediction Method Based on Fuzzy Cognitive Map
Generally in a method on reliability prediction for a system, there is an assumption that the process of each component failure is independent, irrelevant and not affected by other components. However, in the actual working process of a product, the life change caused by dynamic influences among the components of the product should not be negligible. In this paper, a method on reliability prediction based on fuzzy cognitive map is proposed, and a case study using system in package (SiP) is given to determine the life of each component of the SiP under the state of dynamic mutual influences.
