Abstract
In this paper, our aim is to resolve the problem that is security returns are influence by random uncertainty and fuzzy uncertainty in portfolio selection. First, the continuous fuzzy random entropy is defined for the first time to measure the portfolio risk. Then a mean-continuous fuzzy random entropy model is proposed in a more complex market. As an ending, we use a numerical example to illustrate this approach. The results show that the obtained efficient frontier of the portfolio is effective and the continuous fuzzy random entropy can present well the security uncertainty in the more complex market environment.
