This paper introduces the concepts of CSCW, describes the present state and discusses the problems to be solved, primarily focusing on human computer interaction, concurrency control and collaboration management. According to the research on cooperative characteristics of user actions in CSCW systems, this paper proposes a software architecture model of cooperative systems, Arbor. Its main contents include: Layered structure The Arbor model divides a cooperative system into five layers according to functional decomposition: device layer, concept layer, intention layer, cooperation layer, and computation layer. It deifies user actions and reifies the results of the actions to implement multi-level collaboration among multiple users. Multi-level collaboration obtains finegrained collaboration of the cooperative system and improves its collaboration efficiency.

本文首先介绍了计算机辅助协同工作的基本概念，着重从人机接口，并发控制和协同管理等功能方面介绍了协同系统的现状及其软件结构存在的问题，然后，基于对协同系统中用户动作的协同需求和协同特性的研究，针对目前协同软件系统存在的问题，提出了一种协同系统软件结构模型Arbor，它的主要内容包括：层次结构 Arbor模型从功能上将协同软件系统分为五层：设备层、概念层、意图层、协同层和计算层，它通过对用户动作的多层抽象和对动作结果的多层例化，实现多用户之间的多层次协同及感知，层次结构增强了系统的灵活性和适应性，方便了系统的开发，同时，多层次协同的方法获得了细粒度的协同感知，提高了协同效率。

The system overall goal is that : On the computer network, the database and developing platform, using existing software, dispossessing the corresponding hardware equipment, developing a simply, practical, to be easy to maintain, to have the good man-machine interactive contact surface the auction off system.
