( 3 ) based on the var model, the raroc performance valuation approach can reflect the real performance of the portfolio manager and provide the coherent standard for the allocation of risk limitation and the construction of the incentive compatibility constraint mechanism in the financial instiutions

  18. We investigate the decision - making problem with a finite set of alternatives, in which the decision information takes the form of a fuzzy preference relation. we develop a simple and practical approach to obtaining the priority vector of a fuzzy preference relation. the prominent characteristic of the developed approach is that the priority vector can generally be obtained by a simple formula, which is derived from a quadratic programming model. we utilize the consistency ratio to check the consistency of fuzzy preference relation. if the fuzzy preference relation is of unacceptable consistency, then we can return it to the decision maker to reconsider structuring a new fuzzy preference relation until the fuzzy preference relation with acceptable consistency is obtained. we finally illustrate the priority approach by two numerical examples. the numerical results show that the developed approach is straightforward, effective, and can easily be performed on a computer
