方案比较法在输气管道设计中的应用

Application of project comparing approach in the design of gas pipelines

以输气管道设计为研究对象,用每年管网造价和管网运行费用构成输气管道的年当量费用,并以此为目标函数,建立了输气管道优化设计方案比较法的数学模型.运用方案比较法在进行管道设计时可为设计者提供有价值的决策依据,选择合理的方案.

With the study of the gas pipeline design, the annual cost of the network and network operating costs forming valent weight cost of the gas pipeline, as well as the objective function, the mathematical model of project comparing approach in gas pipeline optimization design is established. With the use of project comparing approach in gas pipeline design, designers can provide valuable basis for decision-making and select the reasonable option.
