群组层次分析法在海底管道工艺设计中的应用研究

Study on Application of GD-AHP(Group decision-Analytic hierarchy process) in Marine Pipeline

海底管道工艺设计是海底管道总体设计中的重要组成部分,工艺设计方案的优劣将对海底管道设计、施工安全、维护产生重大影响。由于决定工艺方案的因素涉及到技术、经济、环境等诸多领域,问题较复杂,到目前还没有形成一套量化优选工艺方案的科学模式。文章提出了一种基于工程实践及群组层次分析法(GD-AHP)的海底管道工艺方案半定量评价模型,建立了相应的评价指标体系,并应用专家群组决策理论进行科学优选。将该模型应用于实际工程项目论证,结果表明本评估体系合理有效。

This paper presents a semi-quantitative assessment model of marine pipeline process scenario based on engineering practice, establishes the relevant assessment system, and carries through scientific optimum selection using the specialist group decision-making theory. This model is applied in a practical project evaluation, and the conclusion shows that the assessment system is reasonable and effective.
