Application of Weighted Grey Target theory on informatizational assessment of ports

According to the incomplete information due to the imperfect index of port informatizational evaluation and instability of the relevant data, the Weighted Grey Target theory is introduced to assess the informatization status of ports. This paper constructed the evaluation index, evaluated the index´s attributes combining the Analytic Hierarchy Process (AHP), and selected 11 ports to rank order by using the Weighted Grey Target model. It concludes that Port of Shanghai has won the highest score belonging to the assessment Class I area, while Port of Lianyungang, Yantian, Jinzhou, Jiaxing and Wenzhou have got low scores belonging to the assessment Class IV area. The result shows that the Weighted Grey Target theory is a simple and effective method to assess the port informatizational performance.
