摘　　要：研究和分析现有的发言权控制策略,介绍了基于JAVA和VRML技术的分布式产品协同评估系统,针对本三维图形实时协同评估系统的特点,采用特定的发言权控制策略,进行并发控制。在借鉴已有的发言权控制策略的基础上,提出将请求和时间周期相结合的控制策略,即平等发言权和多重队列轮换法的协同发言权控制策略,对不同的参与人员数量,采用不同的策略,并对其在该系统中的实时性、公平性进行分析。Current floor control strategies are analyzed and a distributed collaborative assessment system is introduced, which is based on JAVA and VRML technology to realize synchronous collaborative assessment. According to this synchronous collaborative assessment system based on 3D graphic, special floor control strategies are adopted for concurrent control. On basis of researching the usual concurrent strategies, strategies that combine request and time cycle methods are proposed, that is equal right for floor control and a multiple queues rotation mechanism. These two strategies are applied according to the amount of participators. And the real time ability and equity of these two strateqies applied in this system is analyzed.
