【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.更多还原
