Abstract: In order to reflect the initiative, autonomous and collaborative characteristics of the designer in collaborative product development process simulation, an integrated simulation model is formulated centered on the designer’s intelligent agent model. Sub-models of designer, task, product information, resource and organization are defined and described. The designer’s behavior protocols of the intelligent agent model are studies systematically. Thereafter, a product development process simulation platform is developed based on the agent model, which realizes visual designer-oriented modeling and simulation functions. A series of simulation experiments are carried out to validate the integrated simulation model. Finally, the model is applied to a motorcycle collaborative design project to optimize the organization factors. Designer-oriented simulation provides a quantitative and dynamic method to analyze human and organization factors in collaborative product development process.
