| Abstract: | Conclusions Theoretical and practical results indicate that the SAA method can be efficiently applied for the solution of road construction optimization problems with allowance for construction dynamics.We have experimentally established the possibility of replacing the traditional  static designs, based only on average initial data, with dynamic designs relying on accurate information about the current conditions. The dynamic designs can be used to develop the best managerial decisions for roadbed construction.Our results again emphasize the need for the development of a qualitatively new scientific-technical base of construction controls relying on integrated application of efficient mathematical methods and computing tools for the analysis and optimal revision of design, technological, and organizational solutions. Our research has led to the development (jointly with Glavbamstroi design office) of a proposal for a program of radical improvement of preparation in the construction industry by establishing an interactive link between CAD systems and MIS. The proposal has been approved by the college of the Ministry of Transportation Construction.This research is merely the first step toward the development of optimization algorithms for an integrated computerized management system for road construction, which should substantially accelerate the search for best design and managerial solutions by allowing sequential optimal revision of earlier alternatives in different stages of the life cycle of the project, strengthening the currently weak feedback from construction to design, and encouraging the experts to assume an active role in on-line search for the best man-machine solutions. Our results to a certain extent have stimulated the organization of design and construction associations, approved by the Resolution of the Central Communist Party of the USSR and the Council of Ministers of the USSR, whose function is to improve the economics of construction and in particular to accelerate large-scale adoption of research results in practice.In addition to the authors, many other researchers took part in this project: V.
