With the proliferation and aggregation of advanced production technology and information technology, several regional intelligent manufacturing clusters have taken shape in China. The development of intelligent manufacturing, which is highly technical, innovative, and informatized, needs the support of more professional producer services. Considering the broad scope of producer service supply-demand in regional intelligent manufacturing, this paper takes the intelligent manufacturing cluster in the Yangtze River Delta as the object, analyzes the limited access to producer services required for production operations, and proposes to integrate and supply the resources of multiple service agents in the region in a dynamic and collaborative manner. Then, the Multi-Agent model was constructed for the producer service supply chain, and the relevant factor libraries and decision libraries were designed. Finally, an empirical analysis was carried out to evaluate the stability of the collaborative operation of the producer service supply chain under the effect of some collaboration factors. The results show that the model has a certain theoretical reference value.
