Application of hierarchical grey analysis in quality assessment of highway engineering

This paper considers the quality of highway engineering. First, the index system for highway engineering quality evaluation is established. Then, according to the difficult of the quality of highway engineering evaluation, analytical hierarchy model (AHM) and grey mathematic are introduced in the quality of highway engineering. AHM is easy to implement and hierarchical grey analysis theory are good at dealing with the merits of the poor information systems. This method combines the merits of AHM with grey mathematic to evaluate quality of highway engineering. Finally, combining with a example, specific algorithm of AHM with grey mathematic for quality evaluation of highway engineering are given. The results show that the method is applicable and realistic with regard to the core of a highway quality management.
