Abstract
For computable models and numerical methods on the basis of the reactive distributed systems with a graphic interface the concept and the architecture of network object-oriented information libraries are discussed. Calculation of modelling situations is driven by the events and workflow constructed by the user using components saved in library and their data.
The library is intended for saving, easy access and the calculation of wide range set of models solved by iterations, including complex models on the basis of systems of equations of private and ordinary derivatives.
The example of calculation of complex system of mass transfer model and population dynamic model by means of working system Niva is shown.
