Abstract: With the increasing scale of software and the increasing complexity of software,the design and development of large-scale systems such as aircrafts and ships are often completed by teams with different professional fields and functions.Aiming at the problem of incomplete model caused by missing information between local models and model inconsistency caused by conflict between update operations,this paper proposes a method of modelcombination and update (MCAU) based on the meta-model.This method defines the collaborative relationship and update operation on the meta model,which can ensure the integrity and consistency of the model in the process of collaborative modeling.An example is given to illustrate the application and analysis of the proposed method.Secondly,this paper proposes a model driven software collaborative modeling framework(SCMF),which can effectively support the extension of multiple modeling languages.Finally,this paper develops a software collaborative mode-ling prototype system(CorModel) based on eclipse framework,and further verifies the effectiveness of MCAU through related experiments.

Key words: Collaborative modeling, Conflict detection, Meta-mode, Model consistency, Model integrity
