| Abstract: | An optimal model is set up for urban gas pipeline network, taking the minimum fee of construction and operation as object function, and taking as constraint condition the stable state analysis, flowing capacity, pressure on every node point, and the pressure restriction, etc. According to the features of the pipeline structure, the solution can be obtained by the Method of Genetic Algorithm, the important fitness function of which can be established, thus to give out a method of pipeline coding. Through calculation on the programming examples, it is shown that the Method of Genetic Algorithm is advisable one in the field of the optimization of gas network. |
