Solution for implementation constraints of workflow patterns
针对工作流模式执行约束的解决方案

After analyzing new workflow patterns in depth, it is found that the present extended Xinpai-driven model can support most of them, but the implementation constraints of some patterns can not be supported yet, as the 8 patterns listed. In response to this problem, this paper proposed the formal solutions so as to achieve better support to workflow patterns by Xinpai-driven model. Firstly it was necessary to define formally the specific region corresponding to every pattern and provided the algorithm to identify the region. Secondly it put forward a strategy which could ensure corresponding region to run safely by ensuring every Xinpai box's safety in corresponding region.
