摘要
并行工程的实现要求多个应用特征空间在保持信息完整性、一致性的前提下实行双向映射。以产品全局特征模型为中心的映射模型将映射过程分解成，从全局特征到领域抽象特征再到领域具体特征的三个层次进行。映射知识以特征为对象按面向对象技术表达和组织，由系统知识库和过程知识库共同驱动双向特征映射的实现。
Feature mapping is in particular needed to support the concept of Concurrent Engineering with multiple feature views. Two-way feature mapping centers on product general model. The mapping process is from general feature to abstract application feature and to concrete application feature . Mapping knowledge is represented and organized by means of Object-Oriented technique. System KB and procedure KB drive the two-way feature mapping.
