Model of Product Development Complex System and Analysis of Its Dynamics Mechanism

Take system dynamics as main frame of study,and use SVM to get the non-linear mapping relationship among units,and then put forth a new method of modeling product development complex system(PDCS) to construct the model of PDCS;Second,use rough set method to analysis the feedback loop of flow-chart of the system,so as to look for the non-linear dynamics correcting mechanism of pro-duct development.At last,use factual projects of product development to simulate and verify the model of PDCS found with the new modeling method.The model and its simulation system can illuminate factually the essentiality of the evolution process of new product development,and put forward the structure for the steady of PDCS,so as to resolve the problems such as low success rate of new product development and being hard to forecast and control the evolution process of PDCS,and so on.
