【摘要】 作为近年来发展最为迅速的几项新技术之一,工作流技术是实现企业业务过程建模、仿真分析、优化、管理与集成,从而最终实现其自动化的核心技术。采用工作流管理将使企业按照要实现的主要业务流程而不是传统的按照功能来配置人员的组织结构,从而大大缩短主要业务过程的处理时间,提高对市场的响应能力。 但是,工作流系统建立在不同的开发环境上,其实现方式会有很大的区别。我们在实践的过程中发现,如果基础环境很好,工作流可以利用已有环境上的机制简化系统的实现。 本文首先对工作流技术起源及其定义和工作流管理系统WfMS做了简单介绍,然后介绍了工作流异常处理的概念、范围、分类,以及异常的探测和处理方法。随后给出了我们开发的职业技能鉴定管理信息系统的设计和实现。与通常的异常处理机制不同,本文所讨论的工作流异常处理机制在规则库的基础上引入了事务模型,保证了处理之后数据的一致性和完整性。最后以系统中的流程为例说明了这种异常处理方法。

【Abstract】 As one of the new technologies that develop most rapidly recent years, Workflow technology is the key technology that assists enterprise business process realize modeling, simulation, analysis, optimization, management and integration, and finally automation. Adopting workflow management facilitates enterprise configure personnel organization according to main business process instead of functions traditionally, sequentially shorten main business process time greatly and improve response capability to market change.However, the realization solution of workflow system will be quite different according to diverse developing environment. In practice, we discover that utilizing exiting mechanism realize workflow can simplify whole system if the infrastructure is good enough.This paper first introduces the origin and definition of workflow technology and Workflow Management System (WfMS). Then it comes to the definition, types, monitoring and handling of workflow exceptions. Later this paper describes the design and implementation application of vocational skill auditing management information system . Unlike other WfMS exception handling methods, the exception handling mechanism of workflow discussed in this paper introduces transaction model. In the last part of this paper, an instance of the workflow exception handling process is demonstrated by a flow in our system.
