When planning and managing scientific and technological progress It Is necessary to pay due attention not only to each Index but also to the whole system of Indices, In this process an Important role Is played by the •through• Indices~ While going further In perspective (from annual to five-year and then to 10 or 15-year planning) certain details and nuances of scientific and technological progress become less clear. In some cases there may be no need for great details. and In others It may be difficult to forecast them. This poses some dlfflcultues In aggregating the Indices characterizing a certain area of scientific and technolgolcal progress In ~arlous planning documents. such as the Principal Guldel lnes and Five-Year Plan. There are three approaches to this problem. The first approach aggregation consists In existing technology which period. In solving the problem of Index using the Index characterizing the will be also used In the perspective 292 The second epproech Is reelted to the case when the perspective direction of scientific and technological progress ts already Identified and Its prospects are more or less clear, even If It has not yet material lzed In lridustrles. The third approach Is applied when e new phenomena Is not clear but the area of Its possible appearance Is known. In this case among the aggregated Indices they Introduce a future Index without the title, I Ike other new processes or products. While elaborating the planning documents of different orders and time horizons It Is necessary to ensure aggregation and detailing of their targe·ts and Indices. Without this the 
analysis: The text appears to be discussing the planning and management of scientific and technological progress, with a focus on aggregating indices to assess its influence on progress. The language used is technical and formal, suggesting a context of policy-making or strategic planning. The text does not mention specific industries or sectors, but rather refers to "scientific and technological progress" in a broad sense.
