摘　　要：针对制造企业产品协同设计过程中团队成员间的协商和交互的需要,设计了一个支持产品协同设计的即时消息(instantmessageI,M)系统模型。提出将成员角色和消息等级结合起来优选TCP/UDP协议的方法,从而提高了系统性能。同时设计了一种即时消息格式来规范消息的解析和封装。接着分别对IM服务器和客户端的主要模块的设计进行了说明。并采用Microsoft.NET平台的C#进行了具体的实现。In order to solve the problem of collaboration and exchange between design teams during product collaboration design in manufacturing enterprise, an instant message model for supporting product collaboration design is put forward, and a method to select TCP/ UDP is presented by combining member role in enterprise with the level of messages, which could improve the performance ofthe system. At the same time, an instant message formation is designed to standard parse and encapsulation of message. The main modules ofserver and client ofthe IM are introduced respectively. Atlast, the system is implemented by utilizing C# programming langnage on the Microsoftlnet platform.
