复杂产品虚拟样机描述中的多粒度建模方法

Multi-Granularity Modeling in Virtual Prototype Description of Complex Product

多粒度建模是支持虚拟样机可扩展、可演化建模的一种新方法。为支持从不同层次、不同粒度上进行复杂产品虚拟样机模型的描述,提出了多粒度建模框架,研究了多粒度建模的通用方法,多粒度模型的形式化表示及数据描述格式,在此基础上,给出了多粒度模型的建立过程及关键技术。

Multi-Granularity Modeling （MGM） is a new approach to supporting extensible and evolutional modeling for Virtual Prototype （VP）. To describe VP of Complex Product in different levels and granularities, MGM framework was proposed. General Method of MGM was researched, and formal definition and data description format of Multi-Granularity Model were proposed. Finally, modeling flow and key technologies of MGM were given.
