基于网格服务的电子商务自适应工作流模型

网格服务是分布式应用的新技术，能够为电子商务的工作流框架设计和工作流管理提供更为先进的技术支持。基于网格服务的工作流管理系统具有较好的自适应性、分布性和动态性。自适应工作流框架（AWFF）是一个分层结构，将工作流模型分为功能层和实例层。功能层定义了整个工作流的基础功能模型，实例层以事件触发机制为支撑，可根据动态的网格环境和多变的客户需求，通过网格服务实现进行自适应。将自适应工作流框架应用到网络电子商务系统中，能够更好地适应分布的、动态环境，提高整个流程的可控性和管理效率。

E- commerce Auto- adaptive Workflow Model Based on Grid Service

Grid service is a new technology for distributed application,it provides an advanced technical support for e-commerce workflow frame design and workflow management.The workflow management system based on Grid service has preferable auto-adaptability and can be more distributed and dynamic.The auto-adaptive workflow frame(AWFF)is a multi-layer structure,which divides the workflow model into two layers,namely,the functional workflow layer and the instance workflow layer.In the functional workflow layer,the fundamental function model of entire workflow is defined,while in the instance workflow layer which is in the support of Event-Trigger-Mechanism can adjust itself in response to the dynamic Grid environment and the variable client demands.The AWFF applied into e-commence can better adapt the distributed and dynamic environment,and improve the flexibility and efficiency of whole workflow.
