为了克服施工方案优选中多目标之间的不可公度性和矛盾性,在模糊理论分析的基础上,运用格序决策方法,并且结合Kaufmann距离或贴近度的概念,建立了施工方案优选模型,对可行的备选施工方案进行优选。结果表明,运用三角模糊数可以将施工方案中的定性指标量化,而应用格序结构可以将定量指标的预测结果和定量指标的模糊概念进行统一的公度,实现基于不同目标下的施工方案的综合评价,最终通过Kaufmann距离计算方法,得出各方案之间的先后顺序。最后通过具体算例验证了该方法在施工优选过程中的实用性以及有效性。
In order to overcome the incommensurability and contradiction between the multi-objectives in the construction scheme optimization, based on the fuzzy theory analysis, using the lattice decision method and combining with the concept of Kaufmann distance or closeness, a construction optimization model is established, The feasible alternative construction scheme is optimized. The results show that the use of triangular fuzzy numbers can quantify the qualitative indicators in the construction scheme, and the use of the structure of the sequence can be used to unify the predicted results of quantitative indicators and the fuzzy concepts of quantitative indicators to achieve the goal of construction based on different objectives Comprehensive evaluation, and finally through the Kaufmann distance calculation method, draw the order between the various programs. Finally, a practical example is given to verify the practicability and effectiveness of this method in construction optimization.
