通过定义 Petri 网变迁的指标函数,给出一种基于变迁指标的 Petri 网分解方法,通过分解得到子网系统均为结构简单的 T-网。分析了原网系统与子系统在结构性质和动态性质方面的对应关系,并且证明了通过子网之间的共享合成可以得到原先的网系统,这为 Petri 网用于复杂的物理系统分析提供了可靠的理论依据和技术手段。
Networked agile manufacturing (NAM) is a new manufacturing paradigm for the 21st century. Manufacturing businesses based on NAM are characterized by virtual organization, innovation, global sourcing of materials and production centered on the workforce. Therefore, NAM requires a knowledgeable, motivated workforce. This paper reviews the literature related to developing an NAM curriculum to: (1) review the progress for organizing manufacturing information, (2) study the fundamental technologies impacting NAM, including product data management (RDM), enterprise resource planning (ERP), and component/supplier management (CSM), (3) present a definition of NAM and its conceptual framework, and (4) generalize the basic NAM curriculum. The NAM curriculum can be used for developing a manufacturing course.
