Multi-granular resource access control is a key issue of Cloud Manufacturing (CM). On basis of the attribute of CM access control, multi-granular resource access control model (MGAC) was proposed and conversion method of MGAC directed graph was analyzed in this paper. Generation method of the simplest authority overlay graphic was put forward based on vertex overlay matrix. The authority migration path confirmation method was deeply studied under capacity constraint. Vertex access repeated matrix was presented and the confirmation method was established. By the verification of experiment, relationship between objective number, vertex number and average available capacity ratio and CPU running time was analyzed under unconstrained and capacity constraint. At the same time it was compared with related algorithm performance. The method was proved to be more efficient and can adapt the requirement of CM multi-granular resource access control based on unconstrained and capacity constraint.
