An Approach for Evaluating Securities Companies Based on Cloud Model

Abstract:

This paper aims to construct the evaluation framework of securities companies， analyze the comprehensive competitiveness of listed securities companies in China， and provide reference for the ratings of securities companies. Therefore， a comprehensive competitiveness evaluation model for securities companies is proposed based on cloud model and grey relation analysis-technique for order preference by similarity to an ideal solution（GRA-TOPSIS） method. Besides， the cloud model is used to reflect the fuzziness and randomness of decision-makers’ evaluation information. The GRA-TOPSIS method is conducive to determining the weights of evaluation criteria of securities companies and the ranking of the candidate securities companies by combining the advantages of GRA and TOPSIS. Moreover， 30 securities companies listed in China are utilized to verify the validity of the model. Furthermore， some suggestions are proposed for securities companies to improve their competence.
