Abstract: To solve low agility in production scheduling problem of the manufacturing enterprises, an agile production scheduling modeling (APSM) method was proposed to maximize the capacity of whole production system, based on Petri net, object-oriented technology and agile manufacturing ideas. By developing APSM scheduling model and extending the traditional production capacity function, a new extended capacity function was obtained. An agile production scheduling model was established. In the model, capacity bottleneck stations were taken as the core of dispatching, then other stations were satisfied with pulling or pushing ways. The agile production scheduling model could directly reflect real-time production circumstances. Through the example of agile scheduling, bottleneck station capacity was enhanced, production cycle was shortened and the entire manufacturing system profit was increased.
