[en] A program complex designed for analysis of transport processs in a tokamak is described. The given system differs from the programs which are currently used by the fact that the user can do without programming languages. Transport phenomena are written in the form maximally closed to the form of equation writting in articles. To record transport coefficients, various elementary and other processes one can use library formulas describing a wide set of physical processes. Creation of a program of numeric solution on the base of assigned equations of analysis or calculation of transport processes is realized in TRANSITOR system automatically
