Although many workflow models have been proposed, analyses on artifacts are seldom discussed. A workflow application with well structured and adequate resources may still fail or yield unexpected results in execution due to inaccurate artifact manipulation, for example, inconsistency between data flow and control flow, or contradictions between artifact operations. Thus, artifact analysis is very important since activities cannot be executed properly without accurate information. This paper presents a three-layer workflow model for designing a workflow and characterises the behaviour of an artifact by its state transition diagram. By abstracting common usages of artifacts, six types of inaccurate artifact usage affecting workflow execution are identified and a set of algorithms to detect these inaccurate usages in workflow specifications is presented. An example is demonstrated and then related works are compared. 相似文献

基于对面向服务的体系结构(SOA)下服务角色划分以及对当前分布式应用特征的分析,通过引入抽象资源和抽象服务的概念,提出了一个面向服务的将工作流划分为业务工作流(BWF) 、抽象工作流(AWF)和执行工作流(EWF)的工作流映射模型.它将业务工作流的部署、执行转换成两个映射--业务工作流到抽象服务工作流的映射和抽象服务工作流到执行服务工作流的映射 .这一模型为当前Internet上基于Web服务和Grid服务的分布式应用提供了一种动态的组织、部署和执行方案.此外重点探讨了实现该模型下多层次工作流计算机辅助映射的应用模板技术,应用模板定义了各个抽象资源和抽象服务在特定应用任务中必须遵从的约束及必须提供的相关元数据. 相似文献

Workflow management technologies have been dramatically improving their deployment architectures and systems along with the evolution and proliferation of cloud distributed computing environments. Especially, such cloud computing environments ought to be providing a suitable distributed computing paradigm to deploy very large-scale workflow processes and applications with scalable on-demand services. In this paper, we focus on the distribution paradigm and its deployment formalism for such very large-scale workflow applications being deployed and enacted across the multiple and heterogeneous cloud computing environments. We propose a formal approach to vertically as well as horizontally fragment very large-scale workflow processes and their applications and to deploy the workflow process and application fragments over three types of cloud deployment models and architectures. To concretize the formal approach, we firstly devise a series of operational situations fragmenting into cloud workflow process and application components and deploying onto three different types of cloud deployment models and architectures. These concrete approaches are called the deployment-driven fragmentation mechanism to be applied to such very large-scale workflow process and applications as an implementing component for cloud workflow management systems. Finally, we strongly believe that our approach with the fragmentation formalisms becomes a theoretical basis of designing and implementing very large-scale and maximally distributed workflow processes and applications to be deployed on cloud deployment models and architectural computing environments as well. 相似文献
