FORMULATION OF THE OPTIMIZATION PROBLEM FOR UNDERGROUND ENGINEERING NETWORK ROUTES

Abstract

The article considers the implementation of methods for optimizing underground external engineering networks in order to reduce construction costs. For this purpose, the problem of optimizing the route of such networks is set in the form of a nonlinear programming problem. The route is modeled by a spatial polyline with rectilinear segments, and the coordinates of its vertices are considered design variables. The ground surface in the designated area is modeled as a continuous function of two coordinates in the plan using BIM technologies, which ensures the automated use of topographic information when calculating the volume of earthworks and checking compliance with constraints specified by standards requirements. The main result of the study is the formulation of the problem of optimizing the route of the engineering network taking into account the terrain.
