Study on enterprise's life cycle based on fuzzy set theory

There are many methods to judge enterprise's life cycle. This paper unifies the related method of fuzzy mathematics, and carries on the new division method of enterprise's life cycle. First, this paper bases on flexibility and controllability, and takes fuzzy mathematics as study tool. Through analyzing subordination functions and their mathematical expressions of P, A, E, I four factors, it has carried on the fuzzy recognition to each stage of enterprise's life cycle, and established the method based on the fuzzy set theory. Through analysis, we discover this method has been operational and has the important research value in the determination of enterprise's life cycle.
