ＣＩＭＳ工程的重要思想是将企业全部生产经营活动视为有机整体，可以集成与优化。但是，目前我国ＣＩＭＳ工程中ＰＤＭ与ＭＲＰⅡ分系统并未真正实现紧密结合与集成，甚至是彼此分离，无直接衔接。在实践经验的基础上，作者探讨了基于二维模式的ＰＤＭ与ＭＲＰⅡ紧密衔接可行性，提出了实现这一衔接的初步设想 The important idea of ​​CIMS engineering is to regard all the production and business activities of an enterprise as an organic whole, which can be integrated and optimized. However, at present, China’s CIMS project PDM and MRP Ⅱ subsystem did not really achieve close integration and integration, or even separate from each other, no direct link. On the basis of practical experience, the author discusses the feasibility of close connection between PDM and MRPII based on two-dimensional model and puts forward the tentative idea of ​​this connection
