%X The existent ill-structured architecture and the low efficiency of analysis and design methods during the implementation of enterprises information systems are the main factors, in regard to the continuous changes of the business processes , which disable the quick response capability of enterprises and are apt to resu lt in potential errors, delays and extra costs. On the basis of the componentwar e and distributed object technology, a hierarchical model of knowledge-based bu siness objects is proposed in this paper, within which the medium-grained proce ss-components mask the intricate interactions between fine-grained basic busin ess objects by means of the special dataports mapping and built-in rulebase con trol. Also, four kinds of reconstruction strateqies are available under this mod el. Finally a kind of Petri net-based approach to model the business objects' b ehaviors in the business processes is given. Through this approach, the unambigu ous relationship between the model constructs and the distributed object servers can be explicitly established so as to facilitate the rapid development of ente rprises applications.
