Transformations of linguistic and numerical data in computerised decision support system

The article discussed the issue of the bi-directional data transformation (from the linguistic form into numerical, and vice versa) in the computerised decision support system (DSS). The system uses multi-methodical research approach, which is to provide a simple and useful form of functionality of different, complementary decision support methods. Data transformations are based on the use of fuzzy set logic and specially developed for thus purpose scoring and linguistic scales of the ordinal nature.
