This modeling method is discussed from three aspects as follows. Firstly, on enterprise model framework, enterprise model expressed by this modeling method is more particular than other, since there are the views of product process and relation in it. Secondly, in this modeling method, the modeling process that the process model of products is created first of all and other models are created according as it is presented. Using this method, enterprise model is clear and consistent. Thirdly, on the representation of views, the traditional method of IDEF is appreciably improved.

论文从三个方面对此建模方法进行了阐述：1，企业模型框架方面，基于产品过程模型的集成化企业建模方法中的模型框架包含了产品过程视图和联系视图，因而它表达的企业模型更为丰富、详细；2，企业建模过程方面，提出了首先建立企业产品过程模型、再以此为核心建立其它模型的建模过程，这样建立的企业模型主次分明，各视图之间有机统一、协调一致：3，模型视图的描述方法方面，对传统的IDEFIntegrated Computer—Aided Manufacturing(ICAM DEFinition模型表达方法提出了一些改进建议。

Until recently, the convergence of the Rosen"s arithmetic has been proved. The projection gradient method is the generalization of Steepest decent method to constraint problem. So it does have a faster convergence speed that the fastest decent method .
