Automatic Building Process of Self-Closed Modified N-tree

Abstract

Some features of prevailed workflow like Petri net and Grid workflow make them cannot adapt to the dynamic operation. So, we proposed a modified N-tree model to control a workflow. Modified N-tree model can remedy some problems exist in these prevailed workflow models. Firstly, we approve the proposed modified N-tree model is self-closed. This feature makes sure that this workflow can accomplish its tasks, when we change nodes of a well-running modified N-tree workflow before or while its execution. It is the prerequisite of dynamic characteristics of modified N-tree model. And, then we give a method to change this tree dynamically based on the self-closed merit. Finally, based on the dynamic characteristics of this model, we give a method to build on this N-tree workflow model automatically by using left root (LR) analysis method proposed by Mr. D.Knuth. This is the most important performance of this model. DOI : http://dx.doi.org/10.11591/telkomnika.v12i1.3901
