摘要

In order to improve the arrangement of the gathering and transferring of oil-gas pipernnetwork, the mathematic model for solving the multi-objective optimization problemrnwere established. NSGA-II (Non-dominated Sorting Genetic Algorithm-II) programrnwhich has a good global optimization has been compiled to improve the gatheringrnand transferring of oil-gas pipe network performance. Positions of middle stationsrnwere selected as the design variables with investment cost and hydraulic loss ofrnpipelines as optimization objectives. Many techniques in optimization program, suchrnas the real number encoding technique, the random sampling based on expanding thernresearch space, single-point crossover and uniform mutation had been used. Thernsystem of optimization method is formed to be utilized for optimization of gatheringrnand transferring of oil-gas pipe network. Lastly, through one engineering project ofrnthe gathering and transferring of oil-gas pipe network, it is shown that economy andrnthe hydraulic performance of the optimized gathering and transferring of oil-gas pipernnetwork has got improvement to some extent.
