As there is a priority in multiple design transaction and multiple design roles in the distributed design traction, this paper studies the distribution hierarchy of collaborative design roles and proposes a membership degree algorithm based on grey related analysis. In this algorithm, design constraint degree about the design roles is acquired through grey related analysis. Under different design constraint degree, design roles and incidence coefficient are acquired together with corresponding matrix. Then the membership degree can be available by the constraint degree and the matrix. Empirical test proves the efficacy and practicability of this algorithm.
