Reliability Problems and Longevity Analysis

The article describes problems of mathematical description of longevity and ageing processes in living organisms. These problems are similar to the problems considered in reliability theory but need development of additional methods to account for the living organisms specificity. The article describes methods for assessment of heterogeneity phenomenon in population, for analysis of stress experiments, for modeling of survival in changing environment. Results of analysis for longevity experiments with warms C.elegans and mediterranean fruitflies Ceratitis capitata are presented. Application of the new methods and results, obtained in biodemography, can be profitable in investigation of technical systems under nonstandard conditions and extreme conditions.
