摘　　要：将天然气管道输送理论、灰色系统理论、最优化理论和决策支持系统理论相结合 ,开发研究出“天然气长输管道设计方案优选系统”(简称GPDOS) ,实现了沿线地形起伏 ,沿线有若干进、分气点的长距离输气管道设计方案优选。文章详细介绍了GPDOS设计的基本过程 :概念设计、功能设计和结构设计。算例在GPDOS上的运行表明 ,该系统的独到之处在于 :实现了天然气长输管道工艺计算和方案优选的自动化 ,实现了多方案计算的任意组合 ;对优化投资费和运营管理费 ,缩短管道设计方案优选周期 ,快速获取输气管道沿线各段直径、壁厚和沿线压气站位置、数目、压气机型号及其组合方式以及输送压力等一系列最优参数 ,提高设计质量取得了明显的效果 ;对更新设计观念 。With the theory of decision supporting system combining the gas transmission theory, the gray system theory, and the optimization theory, 'Gas Pipeline Design Optimization System (GPDOS)' has been developed. Using the system, although rugged topography and several gas entering and distributing points along the line, the optimization of design project of the long gas pipeline is realized. The article introduces the basic process of GPDOS design, i.e. conceptual design, functional design, and structural design. Real cases operated in GPDOS show that advantages of the system are; the process calculation and project optimization of long gas pipeline is automated; and the random combination of different project calculation can be conducted. Also, the system, is very useful to optimize the investment and operation cost, shorten the optimization cycle pf pipeline design project, speedily achieve a lot of optimum parameters of the gas pipeline, such as pipe diameters and wall thickness of different sections, positions and quantity of gas compression stations, types and patterns of compressors, and pressure of gas transmission, etc., and improve the design quality. Also, the system promotes to renew design idea, and have engineering design considered by the thinking method of system theory.
