Компьютерные технологии в проектировании трасс линейных сооружений

Under study are two approaches to creating computer programs for computer-aided design of linear structures trails. The first approach, which realised in the existing CAD of linear structures, is not focused on the optimization of the design decisions, as the computer in these systems is used only for the decision support tasks, but all design solutions are appointed by man. The second approach involves the use of a computer to generate design solutions based on mathematical models and optimization algorithms. In this paper is shown how in the framework of this approach solved the problem of the joint design of longitudinal and transverse profiles of the roadbed of railways and roads. The algorithm of nonlinear programming using particular constraints of the system. It is recommended to use an integrated approach to solving problems of design and creation of CAD with feedback.
