Abstract:In this paper, an approach is proposed to solve the problem of influencing factors analysis. Firstly, a system of information technology innovation’s influencing factors is constructed. Secondly, the error relation schema is given. Then, the method of computing initial-error value is presented. And the initial-error value, the final-error value computing methods of influencing factors which are in the error-transfer-rode, error-transfer-ring and error-transfer-point are built. Furthermore, the method for computing the error-loss value is proposed, and results are analyzed by using the error-loss values and error relation. Finally, an example is used to show the application of the proposed method.
