Abstract: Aiming at the auto parts industry chain supplier enterprise group orders integration problem,this paper put forward technical scheme oriented to the cloud services platform order integration．In order to integrate multiple mapping between abstract based on the established order,multi level mapping tree model was built.Flexible dynamic confi-gurable interface was used to construct acts to the auto parts industry chain cloud services platform mapping rules,and the complex mapping was converted to a direct mapping ．Through order mapping tree hierarchy and mapping integration algorithm,different vehicle plant of large quantities of orders were integrated in heterogeneous components production plan set required for suppliers enterprise group．Results show that the use of multi level order mapping tree model can support for automobile parts industry chain integration of cloud services platform order extended application.
