摘要：With the real-time group editing system, a group of users can view and edit the shared document by communication networks anytime and anywhere. Under the circumstance, it is surely inevitable that many operations from different users are going to conflict. Thus, two issues, the conflict resolution and the consistency maintenance, are the most important for designing and completing the system. In the past, the address space transformation algorithm, invented from the research about the real-time text editing system, could maintain consistency among more sites. The Multi Version conflict resolution approach could preserve users' intentions but not all when conflicts occur. This paper proposes a new solution of conflict resolution, named Intention Combination Conflict Resolution strategy with the document model of AST based on the idea of Multi Version approach. This solution can not only preserve all users' editing consistency by intention combination, but also keep all versions of operational objects including conflict operations' combination effects. In addition, the effectiveness of related algorithms is analyzed, and the availability of the strategy is described by a case and proved by our experiment.
