To analyse and forecast the society evolution on each organization level. It is based on study the mathematical models and testing the computer models.
We consider the society as a system. It has the following subsystems levels: biosphere, ethnosphere, sociosphere, psychosphere, anthroposphere. This system has the hierarchical structure. The biosphere is the living base of system. The next level is built on previous one by hierarchical rule. To construct and analyse the mathematical models of society subsystems. They are the separate parts of general system. We make the forecast of society evolution by means of merging the models in whole model.
