Software architecture for the investigation of controllable models with complex data sets

Investigation of a large control system needs rather sophisticated applications, which would satisfy such users' requirements as necessity of unprescribed modifying all elements of model and data set under consideration depending on the current results of calculations; opportunities for use of different methods to solve the same problem or the same part of problem most effectively; typically experimental character of computations defined by contentual task (comparisons, generating of versions to analyse these ore those dependencies, etc); adaptation to the user as an object expert, not as a programmer. There are proposed basic principles of regional modeling and software architecture for creation and proceeding of such models. Socio-ecologo-economical modeling of region with optimization of its development strategy is considered. The main topics are related to software supporting of modeling, model proceeding and representation, usage of optimizing algorithms and creation of optimization procedures for regional development. A sample software application and results of numerical experiments, based on the model of Pereslavl region are also described.
