Abstract: Computer cannot identify enterprise model expressed by graphics so that the information-integrations among models are affected. Thus the method using EXPRESS language of STandards for the Exchange of Product (STEP) Model Data was proposed to express enterprise model. The feasibility and advantages of applying EXPRESS language in enterprise modeling were described. The methods using ENTITY nesting to express enterprise model were expatiated on, and an instance using EXPRESS language to describe reference-model of automobile-industry was given. Hence information in enterprise model expressed by that can directly be transferred through computer, the integration among models can effectively be realized, and the information integration between enterprise model and production-process can be easily treated.

Key words: enterprise model, standard for the exchange of product model data, modeling
