Information Quantity Simulation on Life Distribution

  • The comprehensive evaluation mode of life distribution is prensented under limited data. The mode of the life distribution takes into account the total fit, the consistency with fatigue physics and the safety of the tail regions. The total fit is assessed by correlation coefficient. The consistency with fatigue physics is analyzed by the hazard rate curve of distribution. The safety of design is predicted by examining the change of predicted errors in the tail regions of distribution. The quantitative comprehensive evaluation mode is con-structed based on information theory when life statistical distribution satisfies the total fit, the consistency with fatigue physics and the safety of the tail regions. The utility of the associated methodology is demonstrated by applications to example.
