模糊层次分析法在管道穿越方案优选中的应用

Applications of improved fuzzy AHP in program optimization of pipeline crossing project

介绍了当前管道穿越的主要备选方案,包括沟埋敷设、隧道施工和定向钻施工等。针对层次分析法(Analytical Hierarchy Process,AHP)用于方案优选时存在的不足,引进模糊一致矩阵的概念,利用模糊数学的研究成果,将AHP扩展到模糊环境中,提出了改进模糊层次分析法,解决了层次分析法一般标度繁琐、判断矩阵一致性困难等问题。介绍了该方法的原理和实施步骤,并结合某工程实例,确定了最优穿越方案,验证了该方法的可行性和优越性。该方法操作简单,易于编程,可以推广应用。

Main alternatives of current pipeline crossing project are described, including buried laying, tunnel construction and directional drilling construction, etc. In view of shortcomings of the Analytic Hierarchy Process (AHP) used for program optimization, the concept of fuzzy consistent matrix is introduced and research results of fuzzy mathematics are used to extend AHP to a fuzzy environment, and the improved fuzzy analytic hierarchy process is proposed so as to solve cumbersome general scale, difficult judgment of matrix consistency and other problems of the AHP. The principle and implementation steps of the method are described. Based on a project case, the optimal crossing program is determined and the feasibility and advantages of this method are verified. Due to simple operations and easy programming, this method can be applied and promoted.
