These models must be connected with information configuration structure to ensure data processing and decision support by Russian competent authorities. In this respect, thetask of this article to make a stratified description based on results of complex pre-model analysis ofRussia's pension system.Stratification of economic and social system proposes to determine its different strata (levels of representation) which unveil each of its specific aspects. The study outlines the following strata of Russia's pension system: semantic, flow, structural-functional, algorithmic and information strata. Thereupon, a unified information display format was proposed, allowing to describeeconomic and social system in terms of semantic, flow, structural-functional, algorithmic and information strata using appropriate ideographic tools of computer modeling. The stratified descriptionlogic is based on key indicators relating to target values of average retirement pension and wage replacement rate taking into account government budget restrictions. Principle used in description is a tree of options allowing to determine best combinations of scenario parameters. The main feature of proposed approach is joint use of dynamic system and agent methods of simulation modeling. Brief conceptualized description of data processing procedures was made based on stratification method taking into consideration information system configuration being able to ensure decision support in Russia's pension system.
