| 摘 要： | 提出了一种计算机支持协同工作（CSCW）应用程序共享机制模型－混合式应用程序共享机制模型，解决了分布、异构协同工作环境中集中和复制式应用程序共享在网络流量和分布异构支持方面难以兼得的问题。在应用共享的统一协调控制下，混合式共享机制允许集中和复制式共享机制共存于同一共亨过程中。利用着色Petri技术，建立了混合式应用程序共享机制的分层模型，并对各部分的运行机制进行了分析。分析结果表明，该模型能够有效地描述共享过程中的动态行为，便于系统的分析、验证。

| Abstract: | An application sharing model in computer supported coopenative work (CSCW) systems-named hybrid application sharing (HAS)-is proposed to solve the problem that the centered application sharing (CAS) and the duplicated application sharing(DAS) can't have less data flux and support more application environment at the same time. Under the control and management of the HAS, CAS and DAS can exist in an application sharing process. The hierarchical model of HAS is established by using colored Petri net, and the running mechanism of the hierarchical model is analyzed simultaneity. The results show that the model of HAS based on colored Petri nets (CPN) can describe the dynamic behavior of the application sharing process, and is contributed to the analysis and verification of system. |
