Abstract:

On the basis of the concept of fuzzy subordination and measure, a new method of determining function coefficient is presented and a calculating formula for function coefficient is also derived in this paper. The characters of this method lie in that the effect of function costs on function coefficient is considered apart from the importance of every function. This method is more objective and practical than traditional methods (FD and DAER Methods).

Key words: Subordination, Function costs, Function coefficient
