虚拟产品开发是现实产品开发在计算机环境中的数字化映射，它将极大地缩短产品上市时间。本文提出了虚拟产品开发的定义和基于总线结构的虚拟产品开发体系结构，详细分析了虚拟产品开发的特点和核心内容，以层次结构描述了虚拟产品开发系统，并详细描述了其组成及运行机制。虚拟产品开发的特征表现为开放性、系统性、协同性、沉浸性和智能性。
Virtual product development is a digital mapping of real product development in a computer environment, which will dramatically reduce time-to-market. In this paper, the definition of virtual product development and the virtual product development architecture based on bus structure are proposed. The characteristics and core content of virtual product development are analyzed in detail. The hierarchy of the product development system is described, and its composition and operation mechanism . Virtual product development is characterized by openness, systematicness, synergy, immersion and intelligence.
