Invest project risk assessment based on joint entropy model

In recent years, the study of sensitivity analysis most lay emphasis on linear analysis methods, without taking into account the nonlinear characteristics of the various uncertainties factors, and only consider sensitivity entropy is not enough, that the probability is another side. this paper makes a comprehensive analysis of the investment projects risk factors sensitive entropy and risk occurrence probability entropy to determine the joint entropy of the right for the investment project evaluation index, it builds up a sensitivity analyze model and probability analyze model to get the joint entropy in random environments. In the end, it also supplies a multi-scheme evaluation decision- making model.
