Application of AHP to the comprehensive later evaluation of petrochemical project

Since the comprehensive later evaluation of petrochemical project involves many quantitative indicators and the dimensionality of theses indicators is different, this text adopts AHP to evaluate the comprehensive later evaluation of petrochemical project. The comprehensive later evaluation is divided into four steps: the first step is to design the index system of the comprehensive later evaluation. The second step is to give the evaluation value for every indicator and process the normalization of evaluation value. The third step is to apply AHP to define the weight of every level indicator. The forth step is to arrive at the result of the comprehensive later evaluation based on counting destination layer´s score. The text gives an example of the evaluation last.
