Abstract: In consideration of information development situation of the petroleum equipment manufacturing enterprises, after carefully studying the EPA industry ethernet agree- ment,the topological structure of the petroleum equip- ment EPA manufacturing network is constructed and the performance of the EPA manufacture network is analyze by OPNET simulation software in this paper.The results indicate that it is feasible to use the EPA industry ethernet to construct the petroleum equipment manufacturing net- work,and the OPNET simulation software may be used to confirm the performance of the EPA manufacture net- work.At present,it is an important method to study the performance of the petroleum equipment manufacturing network planning and design.
