摘要:

长输油气管道选线是复杂的多目标决策问题,控制事故风险、降低建设成本是选线的两个主要目标。应用多目标决策理论,以选择风险可接受且建设成本较低的路线为优化目标,提出了长输油气管道选线优化方法。通过研究优化目标的计算方法,分析选线的约束条件,确定网格划分的精度及范围,建立了选线优化模型,运用动态规划算法求解该模型并进行了实例应用。结果表明,基于风险的选线优化方法是可行的,长输油气管道个人风险标准和村庄或建(构)筑物的搬迁情况可作为选线的约束条件,定义特殊区域周边局部范围的地形地貌类型有助于控制个人风险,两个优化目标的权重分配需要根据实际情况进行调整。

Abstract:

Selection of the route of long-distance oil and gas transmission pipeline is a complicated multi-target problem. Accident risk control and construction cost reduction are two major targets for such selection. By applying multi-target decision theoretical approach and with the route of acceptable risk and lower construction cost as optimization target, this paper puts forward an optimization method for selection of the route of long-distance oil and gas pipeline. By investigating the computation method for the optimized target, the paper analyzes the constraint conditions of such selection, determines the precision and range of grid division, and establishes the route selection optimization model. Subsequently, the model is solved by dynamic programming algorithm and a case study is demonstrated. The results show that, the risk-based route selection optimization method is feasible, individual risk criteria of long-distance oil and gas transmission pipeline and relocation of villages or buildings (structures) can serve as the constraint conditions for the selection. Defining the local topography and landform around special region helps to control individual risk. The weighting distribution of the two optimized targets needs adjustment according to actual conditions.

Key words: long-distance oil and gas transmission pipeline, risk analysis, safety planning, multi-objective optimization, route selection method
