CIM环境下PPC及其实现

PPC and Its Realization in a CIM Environment

讨论了在CIM(Computer Integrated Manufacturing)环境下PPC(Production Planning andControl)基本结构及其主要功能,分析了利用在线立体库进行物流控制的重要性.同时对PPC与CAD/CAM的集成模式进行了详细的分析,并提出和分析了PPC在生产基层单位的实现功能模型框架.

This paper deals with the basic structure and major functions of PPC (Production Planning and Control) in a CIM environment. An analysis is made of the importance of controlling the production rhythm by on-line part warehouse. The integrated model of information between the inner function modules is also discussed and the Y-model is used to represent the PPC's position in CIMS. The integration model of PPC and CAD/CAM is treated at some length. The PPC function model frame,that is,loading-oriented production control and self-adjustment in certain areas as well as the control center of workshop using leitstand,is proposed.
