应用服务提供商模式下应用服务定制的机理研究

提出了"功能选配 流程定制"的思路,以实现应用服务提供商模式下的服务定制,满足应用服务提供商用户对应用服务的个性化需求.首先,定义了业务颗粒及其元模型,建立了描述特定应用的三层业务细分模型;分析了业务处理单元之间的多种耦合关系,基于功能树,定义了多种操作算子,进行了业务处理单元之间的解耦操作,实现了功能模块的灵活配置.其次,研究了应用服务提供商系统与第三方工作流系统的集成方式,探讨了应用服务提供商模式下的流程建模和流程实例管理方式,提出域标签技术进行流程实例的逻辑区分;建立了流程模型与业务颗粒的接口机制和调用机制,实现了业务流程的柔性定制.最后,以应用服务提供商模式下的制造协作平台为应用实例,对理论研究进行了说明.

Mechanism of customization for application service based on ASP mode

To satisfy the individualized requirements of application service from the user of Application Service Provider(ASP) mode,a new approach including two-steps was put forward.The first step was selection of function modules.To achieve the goal of flexible functional modules configuration,a Business Granule(BG) was defined and its meta-model was also designed.A three-tier Business Customization Model(BCM) based on the defined BGs was constructed.The different coupling relationships among business process units were analysed.Based on functional tree,some operational operators were defined,and the decoupling among business process units were completed,so that the flexible functional modules configuration was realized.The second step was customization of business processes.Based on the third-party workflow platform,an integration scheme was devised to realize the flexible customization of business process.The common management mode was used to manage those ASP workflow instances identified by a new method named domain label.Also,the interface between the BGs and the workflow process was defined,and the mechanism of employing was designed to achieve the reuse of BGs.Finally,a collaborative manufacturing platform was provided to demonstrate the application of the study result.
