Study of Multi-Agent Task Model Based on Product Structure Breakdown

From the view of task modeling of project process in product data management (PDM) system, a user-task allocation model is put forward based-on product breakdown structure for distributed collaborative product design. The constraints model of function mapping was established between product structure and task breakdown structure. The colored Petri net was introduced into PDM system as the modeling tool to realize product structure model-driven project task management mode and to execute dynamic visible design task scheduling. It is explored to apply multi-agent system to carry out intelligent task management and dispatching. The agent communication and task dispatching framework were implemented.
