The basic theory of the Petri net model is introduced and the characteristics of alternative process planning are analyzed. Then, the modeling of alternative process planning based on Petri nets is discussed in detail. The modeling process is partitioned into three stages: the modeling of feature operation chains and grouped feature operation chains, the modeling of a feature group's setup determination and the modeling of part setups and related machine function. This paper focuses on the first and the third stages. Furthermore, a case study and implementation of system are described.
