| 摘 要： | 在分析影响桩基础选型的各种因素的基础上,根据模糊积分的有关理论,对基于模糊测度的模糊积分加以改进,给出了基于多层模糊积分多元决策的桩基础选型优化模型,应用该模型进行了某工程桩基础的选型优化分析。分析结果表明,在充分考虑影响桩基础选型的各种因素的基础上,基于模糊积分多元决策模型的桩基础选型优化,可以全面合理地刻画影响桩基础选型的各种定性与定量指标,按影响桩基础选型的整体指标优劣进行取舍是合理的。 |

Optimal choice for pile foundation design proposal based on fuzzy integral multi-index decision |
|
| Abstract: | Based on the analysis of effect factors about pile foundation design proposal,the multiple-stage and multi-objective fuzzy integral decision model about definitive set is presented by improving the fuzzy integral on the basis of fuzzy measure.The computer program for applying the model to solve multi decision–making problem is given.The feasibility of its model is verified through the optimal choice for the pile foundation design proposal in practical engineering.The given example shows that this model can be successfully used to optimize the pile foundation design proposal.At the same time,we can easily evaluate the other complicated systems by using the decisional model above. |
| Keywords: | pile foundation fuzzy measure fuzzy integral fuzzy-multi-index decision optimum |
