广义C^nP集成系统多层状态空间及其递阶控制体系结构研究

Study of Multi-Layers State Spaces and Its Hierarchical Control Structure in Generalized C^nP Integrated System

针对产品全生命周期中不同阶段的状态变化，提出了广义CnP集成系统的概念；根据大系统论中的多层状态空间理论，对该系统中的状态空间组成和变化进行了分析；根据理论分析，对该集成系统的控制部分提出了一种递阶控制模式，并对其运行机理作了探讨。

According to the variety of state spaces in different phases during the product life cycle,the authors propose a new concept of generalized C-P (the cooperative technoIogies of CAD, CAE, CAPP, CAM, CAQ and others integrated with PDM system) integrated system in this paper.The component of this system and its variety is analyzed based on the theory of Large Scale System Cybernetics. On the basis of theoretical analysis a kind of hierarchical control model in the integrated system is given,at the same time the background of the control system is explored.
