tions. A series of ministries and departments have accumulated experience In elaborating long-term prognoses. AI I the prognoses elaborated in the country are registered at the AI 1-Unlon scientific-technical Information centre. Beside registration, the Centre performs acquisition of prognostic developments. This work has been started In 1969. A substantial col lectlon has been accumulated of prognoses on the development of enterprises• ~ranches, and regions. By 1977 the col lectlon comprised of about 3000 prognoses, reports on prognostic scientific-research work. Analysis of the col lectlon Indicates that the researchers pay maximum attention In the prognoses to Investigating the prospects of development In the next 15-20 years (up to 1990-1995). About 10-121 of the col lectlon deals with the elaboration of methods·or correction of those elaborated earl ler. The extensive attention given to the problem of methods Is due to the fact that the qual tty of the prognoses, elaborated for the national economic plan and the development of science and technology depends decisively on the level of theoretical­ methodological developments. Institutes of the USSR Academy of Science, the Academy of Sciences of the Ukrainian SSR, also the Committee on scientific-technical prognostication of the All­ Union Council of Scientific-Technical Societies and the lnstlt~tes of the USSR Ministry of Higher and Secondary Special Education deal with the elaboration of methods of prognostication In our country. The wide scope of research In this area has made It possible to provide alI the prognoses, elaborated In the country, with the required methodological materials. Rasaorcb potentials A considerable number of prognostication methods exists currently, as well as a great number of their classifications. The latter depend on the basis or feature laid down In the base of the classification. The methods, ·used In our country for prognostic research, may be ·divided Into 3 big groups tn
