Анализ основных аспектов задачи оптимизации стержневых конструкций с учётом общей и локальной коррозии. Часть 1. Постановка задачи и проблемы, вызванные наличием двух расчётных схем

Abstract

An integrated formulation of the objective for rod-shaped construction optimization in a form of a mathematical programming problem including two analytical models isproposed. It allows to model a corrosion process in a construction intergrally as well as in rod junctions. We analysed problem aspects of the objective caused, first of all, by the appearance of the second analytical model determined by the conditions of afixment. The conclusion about the utility of conversion to a two-stage model of optimization is drawn.
