Metodę prostych można rozpatrywać jako graniczny przypadek metod analitycznych i numerycznych. Od metod opartych na różnicach skończonych różni ją to, że jeden z wymiarów siatki prostokątnej dąży do zera. Oznacza to, że metoda prostych wymaga dyskretyzacji tylko względem jednej zmiennej, podczas gdy druga pozostaje ciągła. W artykule przedstawiono zastosowanie metody prostych w zagadnieniu symulacji...
The algorithm for steady-state optimisation of large gas networks, based upon. The Generalised Reduced Gradient method (GRG) is described. The networks can be of any configuration. The optimisation is treated as a non-linear problem with non-linear constraints. It is assumed that the structure of the network is known, and such a network consists of compressor stations, valves and regulators, all of...
