基于熵权的TOPSIS法地基处理方案优选研究

TOPSIS Method Based on Entropy in Schemes Choosing of Foundation Treatment

地基处理方案优选是工程建设的重要问题。将地基处理方案优选问题归结为多属性决策问题(MADM),建立了基于熵权法的TOPSIS评价模型。运用熵理论确定目标属性的权重,充分利用客观信息,有效避免了赋权的随意性。通过地基处理方案优选的实际应用,表明基于熵权的TOPSIS法结论符合工程实际,且概念清晰,易于掌握。

How to choose the treatment schemes of foundation is an important step in engineering projects. The schemes choosing of foundation treatment is attributed to a multiple decision making problem. An improved TOPSIS based on entropy is applied to the schemes choosing of foundation treatment problems with weights unknown. The weights of scheme attribute are gained by the method of entropy. The making full use of objective information can effectively avoid the casualness in weight determining. The application results show that this method has a good accordance with the reality; it is clear in conception and easy to put into practice.
