工作流管理系統(tǒng)通常對工作流模型進行嚴格的定義。然而，現(xiàn)實情況卻是工作流實例在
運行過程中常常由于信息不足或者需要的資源不可用等諸多原因，而偏離預(yù)先的定義。因此，如何解決工作流實例運行過程中的路徑選擇問題成為當前研究的熱點。本文以前人的研究成果為基礎(chǔ)，提出了一個基于Ontology 的柔性工作流執(zhí)行框架。

Abstract: Workflow Management Systems usually carry on the rigid definition to the workflow models. However, in real life situations, users should be permitted to deviate from the prescribed static workflow definition for various reasons. These reasons include the lack of information and the unavailability of the required resources, etc. So how to solve the question of router-selection in the real life execution of workflow instance becomes the hot issue in the current researches. The paper proposes an ontology-based framework for flexible workflow execution, on the base of former researches.
