办公自动化系统中动态工作流研究

Research on Dynamic Workflow in Office Automation System

传统的工作流系统规定只能够在流程设计阶段对流程进行编辑和修改,在流程开始运行之后就不能再对其进行任何操作。但随着应用的不断深入和企业自身不断发展,业务流程变得更加复杂,控制步骤和流转规则的不可预知性越来越大;业务种类变得更加多样,设计阶段并不能将所有业务都包含进去;业务发生环境和外部条件的变更变得更加频繁,极其容易发生流转失败,进而导致流转的停滞或回退。因此,需要使用动态工作流思想指导工作流模型的设计,在确保不影响工作流正常流转的情况下,允许用户进行动态修改,提高系统的适应性和柔性。

Provisions of the traditional workflow system can only in the process design stage of the process of editing and revising,after the process begins operation cannot be carried on any operation.But with the deepening of applications and enterprise development,business processes become more complex,the control procedure and process rules unpredictability is more and more big;service become more diverse,the design phase will not include all business;the external environment and the condition of business change become more frequent,extremely easy the transfer occurs failure,resulting in circulation stagnation or regression.Therefore we need to design the use of dynamic workflow guidance of workflow model,workflow can ensure that does not affect the normal exchange situation,allowing the user to dynamically modify,improve system adaptability and flexibility.
