灰色关联模型在投标前期决策中的应用——基于层次熵值组合赋权的研究

Application of grey relational model in pre-bid decision-making:based on hierarchy-entropy combined weight-assigning

面对建设市场上的多个项目,承包商采用科学、合理、易于实施的投标决策方法是建设承包市场的现实要求。基于此,介绍改进的层次分析法、熵值法、灰色关联原理及其在建设工程项目投标决策中的运用。根据工程实际,建立投标前期决策指标体系,并用层次熵值组合赋权法确定权重,在此基础上利用改进后的灰色关联分析模型对多个项目进行评价,并通过工程算例验证该方法,证明其能够很好地克服单一方法的局限性,选择出最优的项目,使投标决策更加公正、科学。

In the face of multiple projects in construction market,it is the practical requirement of the construction contracting market that scientific,rational and easily-implementing bidding decision-making methods are applied by the contractors.Based on it,the improved analytic hierarchy process（IAHP）,entropy method and gray relational theory and their application are introduced in bidding decision-making of construction engineering project.According to the actual situation of engineering,the pre-bid decision-making indicator system is established,the weights are determined by hierarchy-entropy combined assigning method,and multiple projects are evaluated by improved grey relational model based on it.This method is validated by engineering examples,which proves that it can better overcome the limitation of single method,choose the best project,and make the bidding decision-making more fair and scientific.
