In this paper we propose a deadlock prevention method for a class of FMS called System of Simple Sequential Processes with Resources (S 3PR). This method is based on structural theory of Petri nets and it is composed by two phases. The first phase adds local control places to the S3PR net such that all uncontrolled siphons of the S3PR net become controlled. We then obtain the augmented S3PR net. When deadlock-freeness of the augmented S3 PR net is not guaranteed, we modify initial markings of local control places. Thus, we obtain the controlled S3PR net. We demonstrate that the controlled net cannot reach a dead-marking and by exploiting its structure, we state its liveness
