基于STEP和CORBA的汽车产品协同设计体系结构

在深入分析STEP标准和CORBA技术的基础上，提出了基于二者的汽车产品协同设计体系结构．该结构可分为四个层次：数据层、通信层、协调管理层、应用层．数据层基于STEP标准，为应用程序提供统一的数据存取环境；通信层的目的是在分布式、异构环境下提供一种透明的数据操作机制；协调管理层主要用于协同设计的过程管理，由工作流管理、协同设计的冲突管理、工程数据事务管理三个模块组成；应用层包括CAX应用软件及其专用的数据读写器．

The Architecture of Collaborative Automobile Design Based on STEP Standard and CORBA Technique

Based on the STEP standard and CORBA technique, the architecture of collaborative automobile design is proposed. The architecture contains four layers: data layer, communication layer, negotiation and management layer, and application layer. The data layer provides an uniform data access environment based on the STEP standard;The communication layer offers a transparent data operation mechanism in the distributed and inhomogeneous environment; The negotiation and management layer aims at process management ,including three modules : working flow management, design conflict management, and session management; The application layer comprises the CAX software and its private read-write software.
