РОЗРОБКА І ЗАСТОСУВАННЯ МЕТОДІВ МАТЕМАТИЧНОГО МОДЕЛЮВАННЯ ДЛЯ ВИРІШЕННЯ ЗАВДАНЬ ОПТИМІЗАЦІЇ СТРУКТУРИ ТРУБОПРОВІДНИХ СИСТЕМ ПРИ ДІЇ ЕКСТРЕМАЛЬНИХ ФАКТОРІВ ЗОВНІШНЬОГО СЕРЕДОВИЩА
In last decennial events, in connection with development new composite materials with broad variety physics-mechanical and chemical characteristics appears the problem of the development physical and geometrical structure pipe systems, providing the most efficient mode of the transport in condition extreme factor external medium. It is shown that in conditions of the extreme factors external medium, the physics-mechanical and geometrical structure of the inhomogeneous composite covering pipe systems renders the essential influence on the modes of the transportation. In accordance with this in condition of the action extreme factors external medium the development structurally inhomogeneous covering from the composite materials can allow to create to compositions, that simultaneous combine high chemical and physics-mechanical characteristic, not attainable for uniform covering. For the formulated of the multicriterion problems of the optimum design of the physical and geometric structure pipe systems, providing the most effective mode of the transport, were worded efficient methods of the decision, offer the efficient ways information the given problem to problem of the optimization with one criterion, are considered the most important statement of the multicriterion problems of the optimum design of the physical and geometrical structure pipe systems TS, in which can be chosen main, fundamental criterion. The most efficient methods of the decision of such class of the problems are offered.
