Evaluation of security investment based on blind number theory

In order to solve security investment evaluation with multi-factor, multi-variable and multi-level attributes, the blind number theory is applied to this paper. By introducing comprehensive faith degree and unascertained measure, multi-agent system based on the blind number theory can efficiently solve the problems such as uncertainty, fuzziness and randomness. The analysis of CNPC shows that the uncertain conclusion synthesis of multi-agent system based on blind number is effective and credible in security investment evaluation. The blind number theory is a reliable method for security investment evaluation both in theory and in practice.
