  3. Although uml activity diagram is magnitude component in uml, which agrees with modeling system dynamic process and describing workflow, it is immature in itself with the characteristic of non - oriented - object and essentially different from other uml diagram, and need to be ameliorated especially when applicated in workflow, own to the following limitation : firstly, activity diagram describes the behaviors of object class that response the inner action, so uml activity diagram is generally on the assumption of that there is no interruption caused by outer events during the process and no time defer, which limits the ability of uml activity diagram discribing complicated process ; secondly, user cannot obtain enough information of object data, and cannot make sure the character of mutual objects because of actually complicated object and relatively simple object expression in uml activity diagram ; lastly, owe to lacking rigorous mathematical basis and strict, effective methods of validation and analysis, uml activity diagram cannot support the simulation and optimization of workflow, let alone optimizating the model based on the result

    Uml活動圖是uml的重要組成部分,適用於系統動態行為建模和描述工作流,與uml的其他圖形工具不同,它本質上是非面向對象的,而且其本身並不成熟,仍在改進之中,特別是在工作流應用方面。首先, uml活動圖描述的是響應內部處理的對象類的行為, uml活動圖通常假定在整個計算處理的過程中沒有外部事件引起的中斷,也沒有時間的延遲,這就限制了uml活動圖對一些復雜過程描述能力。第二,現實世界業務過程涉及的對象數據十分復雜,但是uml活動圖的對象語義卻非常簡略,用戶基本上無法從uml活動圖中獲取關于對象數據的信息,也不能確定參與交互的對象的特徵。
