The article considers the architecture and implementation features of the data exchange subsystem as part of the decision support system based on fuzzy cognitive models "IGLA", developed with the participation of the authors. The subsystem supports importing data about the structure and parameters of the cognitive model from external applications, as well as exporting data about the cognitive model and the results of its structural-target and scenario analysis. In addition, the subsystem implements a report building module that accumulates the results of building and analysing a cognitive model in a single document, which can serve as a technical template for the corresponding publication, if necessary.
