First, this article discusses three kinds of inconsistency that may result from operating system conflict; then briefly introduces some control methods of concurrency in CSCW system and describes two models which are based on different distribution structure-integrated consistency model and local consistency model; and, finally, the article presents a tree structure for achieving local.

The multi-versioning technique based on object replication strategy can meet consistency model while the conflict operations occur in the cooperative graphics editing systems(CGES),but it does not efficiently solve conflict between non-geometry attribute operations and complex graphics objects.

The paper proposes a set of model consistency checkout rules.

Model consistency is one of the main sectors that affects UML multi-view modeling in the larger complicated software system.

However, UML is at last a semi-formal language, so it’s difficult to maintain model consistency.

Beginning with Analyzing the customer satisfaction (CS) and summarizing sevral factors which affect the CS, this paper puts forward a sevice enterprise customer requirement response inconsistent analysis model (inconsistent model in short).
