中文摘要：

分析企业业务过程的特点，提出一种基于角色权限控制的业务过程协同建模方法，通过过程模型的拆分来分解复杂建模任务，确定自顶向下的协同建模步骤，利用基于角色权限控制机制实现业务过程建模人员与访问权限的逻辑分离，在协同建模机制中引入修改锁、冻结锁以及4条加锁规则。仿真实验结果表骐，该方法是有效可行的。

英文摘要：

The characteristics of business process are analyzed, and a collaborative modeling method based on role privilege controlling is provided. Top-down collaborative modeling procedure is built via process model decomposition. A controlling mechanism based on role privilege is also applied to achieve logical separation between modeling user and access privilege. Update lock, freeze lock and four locking principles are introduced into the collaborative modeling mechanism. Simulation experimental results show this method is effective and feasible.
