【摘要】 随着信息技术的发展,企业对资源的管理以及对业务流程的控制要求越来越高。现有的信息管理技术不能满足人们对资源的更大范围的共享,这些资源除了包括信息资源外,还包括计算资源、带宽资源、存储资源等等。由于传统工作流产品存在许多不足,比如:缺乏互操作性、缺乏对并发访问和出错控制等方面的支持,在解决对企业内部复杂业务过程的管理以及跨企业的业务过程的管理方面,传统工作流产品遇到了很多困难。网格作为建立在互联网之上的新一代基础设施,希望将高速互联网、高性能计算机、大型数据库、传感器、远程设备等融为一体,使人们可以透明地使用各种资源,在其提出之后的短短几年,得到国内外研究人员的广泛关注。基于Web Service的工作流产品,旨在规范工作流产品的接口,使企业间无阻碍的交互信息,得到了包括IBM、微软等有实力厂商的支持,发展异常迅速。如何将现有的网格技术和工作流技术相结合,实现对资源、业务的合理管理,成为近几年的研究热点。WSRF作为新一代的网格体系资源管理框架,实现了标准Web Service规范;WS-BPEL作为一种业务过程执行语言得到许多厂商的支持。本论文在分析现有网格工作流产品的基础上,基于WSRF以及WS-BPEL这两种技术,设计了一种网格工作流系统的框架结构,实现了将网格技术与工作流技术的结合,并在该结构的基础上,对网格工作流引擎的核心组件加以实现。更多还原

【Abstract】 With the development of information technology,enterprises get more and more exigent on the management of resources and the control of business process.The existing information management technologies can not satisfy people of sharing the rescourses in a large scale.Besides information resource,it should also include computing resource,bandwidth resource,and storage resource and so on.Traditional workflow products have many insufficiencies,for instance,lack of the interoperability,lack of the support for concurrent access and error control.They encounter many difficulties in managing complex business processes inside the enterprise and those of cross-enterprise.As a new generation infrastructure built upon Internet,grid attempts to combine the high-speed Internet,high-performance computer,large database,sensor,and long-distance equipment together so that people can make use of diverse resources pellucidly.Several years after it’s presented,grid has aroused widespread attention from the researchers at home and abroad.Based on Web Service,the workflow products aim at standardizing the interface and making the enterprises exchange information without any obstacles.It has gained support from some giant manufacturers like IBM and Micro Soft and it develops rapidly. It has become a hot study topic recently how to have the grid technology and the workflow technology integrated and achieve rational management for the resource and the business.As a new generation managerial framework of grid system resources,WSRF implements a standard Web Service criterion.WS-BPEL,as a language of the execution of business process,gets support from many manufacturers. Having carried out" analysis on the existing grid workflow products,this paper designs a framework of grid workflow system based on WSRF and WS-BPEL technologies.It makes the combination of the grid technology and the workflow technology come true and has realized the grid workflow engine’s core components.更多还原
