Abstract
This paper presents a theoretical approach for identifying the dimensi onless mean coefficient of participating fuzzy mass which is the main unknown parameter of the type I or II fuzzy law previously introduced by the author. This method is based on the use of the associated power flow equation, each power term being identified by using a global sta tistical energy analysis of the fuzzy structure (master structure with its fuzzy substructures). Identification is then carried out by solvi ng a nonlinear constrained optimization problem. An example is given t o illustrate the theoretical results.
