Research on the Modeling Method of Production Process of General Assembly of Civil Aircraft based on Petri Network

摘要

The paper describes the Petri Network basic theory and the characteristics of production process of general assembly of current civil aircrafts; and applies the Petri network theory to the modeling study of production process of general assembly of civil aircrafts, puts forward the Petri network based layer decomposition and Top-Down combined modeling method; describes the logic and steps of this method and applies ExSpect software to carry out modeling simulation through cases to demonstrate the feasibility of this method in the modeling of civil aircraft assembly process.
